Mouth Breathing

It is perfectly natural to breathe through your mouth at certain times, such as when lifting a heavy load or exercising. Breathing through the mouth most of the time, however, can cause health problems. These problems can be especially severe for children because it can affect the long-term development of the face.

Most of us bring air into our body through our nose. The nose is designed to act as a natural humidifier and filtering system for the air we breathe. When we can’t get enough air through our nose, however, the mouth takes over. Breathing through the mouth most of the time was not nature’s intent. When this happens, problems can occur.

Why Would Someone Mouth Breathe?

Mouth breathing is a postural habit that can develop for numerous reasons. Below are the most common:

  1. Allergies
  2. Thumb or finger sucking habit
  3. Enlarged tonsils or adenoids
  4. Chronic nasal congestion
  5. Respiratory infection

Each of these five factors make it physically impossible for a person to nasal breathe. If nasal breathing is not possible, the body’s only choice is to mouth breathe.

Mouth breathing changes the way the tongue works—it develops a “tongue thrust.” A tongue thrust affects speech, swallowing, breathing, and chewing in problematic ways.

Facial Growth and Development

Mouth Breathing and How it Affects Your HealthBelieve it or not, breathing through your mouth can actually change the shape of your face and alter your appearance. This is especially true for children because they are still growing. Children whose mouth breathing goes untreated may suffer from abnormal facial and dental development. Symptoms include long, narrow faces and mouths, less defined cheek bones, small lower jaws, and “weak” chins. Other facial symptoms include gummy smiles and crooked teeth. A “mouth breather” facial expression is typically not viewed as an attractive or desirable appearance to have.

Other Effects on the Body

Using the mouth for breathing disrupts our natural body mechanics. It can affect a number of bodily functions and lead to symptoms such as:

  • Headaches
  • Gingivitis and gum disease
  • Sore throat and cold symptoms
  • Bad breath and higher risk for cavities
  • Poor sleep—leading to chronic fatigue
  • Digestive disturbances—gas, upset stomach, acid reflux, etc.

The stem of the problem in many cases is oxygen deprivation. When we take in air through the mouth, less oxygen is able to be absorbed into the bloodstream. Poor sleeping habits often result from lower oxygen levels. In children, this can adversely affect growth and academic performance. It has even been connected to ADD and ADHD symptoms.

In adults, poor oxygen concentration in the bloodstream has been associated with high blood pressure, heart problems, sleep apnea and other medical issues.

Mouth breathing causes posture changes as well. In order to open the airway, the head rests in a forward position and the shoulders slump. This in unhealthy for the spine.

Mouth breathing can also affect the position of your teeth and your bite. The resting posture of the lips and position of the tongue have also been shown to cause problems with the orthodontic treatment—time spent in braces can be longer, and the chance for relapse after the braces are removed is higher.

What Can Be Done to Treat Mouth Breathing

Mouth breathing may seem like an easy habit to change. Just close your mouth, right?

Unfortunately, for the people who struggle with mouth breathing, it is not that easy. This is because all of the muscles of the face and mouth have been programmed to help them breathe in a dysfunctional manner. Their body does not know how to breathe normally.

In order to stop mouth breathing, the muscles must be “re-trained” to function in new ways.

A myofunctional therapist such as myself can be an instrumental figure in helping you learn to breathe in a healthy way. Myofunctional therapists are skilled at helping children and adults gain control over muscle patterning habits, including those involved in mouth breathing.

A consultation with a myofunctional therapist can be very valuable. If the muscles are not re-trained, problems with general health, speech, orthodontic treatment, dental health, swallowing and breathing may persist throughout life. Myofunctional therapy is needed to make the muscular changes associated with mouth breathing.

  2. I am a 50+, female, (mostly) former mouth-breather myself, who was a blue-baby (meconium aspiration), fingersucker, tongue-thruster with allergies, severe asthma, etc. I have the classic face with the recessed chin. I had to have 8 teeth removed from my mouth before getting braces because my mouth was so overcrowded from not growing correctly. I had sinus surgery to open up my severely compromised sinus system (I had only 20% of the normal sinus space and that was filled with yeast) almost 10 years ago. It was very painful but also very successful. To anyone considering that surgery, I would warn you that recovery is tough but I would so it all again for the outcome of being able to breathe with my mouth closed! My issue is retraining: after so many years of mouth-breathing it is difficult to retrain myself, especially when breathing heavily (as when climbing a hill), and while sleeping. I just wonder what my face would have looked like if it had developed correctly, and whether or not I would have had less physical ailments over the years if this had been corrected early. No sense wasting the time, I know, but I still wonder…

    • Thank you very much for your comment and for sharing about your history. You sound very similar to many of my patients. You are correct, it takes a lot of practice to retrain your breathing, and tongue position can play a large role in making it an easier process. This is where myofunctional therapy would be helpful for someone like you. Retraining your breathing, tongue posture, swallowing pattern, and general posture would have been ideal for your recovery 10 years ago. My hope is that someday myofunctional therapy can be done in conjunction with many types of nasal/airway surgeries. I am glad you are able to breath better now 🙂 All my best to you! Sarah

  3. I was unable to breathe throgh my nose throughout childhood and had an operation at 11 to correct this (not sure what it was). However u was given no training on how to actually breathe through my nose and have never done so since – I am now aged 22. My teeth are over crowed and my jaw has not formed properly being narrow at the bottom and too far back, too narrow at the top and teeth do not meet when I bite together. I suffer from sore throats, ulcers and stomach upsets alot. What are he first steps of getting to see a therapist as I woukd really like to try and breathe through my nose.

  4. This is all very interesting for me to read. I am 25 and have breathed through my mouth my whole life; I don’t know why, although I did used to suck my thumb a lot as a child. My lower jaw is further back from my top, giving me the (apparently classic) overbite which I have always been very insecure about. As a teenager my orthodontist suggested an operation to move my lower jaw forward, but I felt that this would make me look very square jawed and unnatural. I have recently tried to correct my mouth breathing and ensure I breath only through my nose but I often feel as though I am not getting enough breath and after a few hours my jaw starts to ache. What can you suggest as I am starting to feel a bit hopeless! : (

  5. I have long face syndrome and I been a mouth breather all my life and now I’m 17. And for a month I started to breath through my nose. Will breathing through my nose now, make my face smaller? Or atleast make it normal a little bit? PLEASE ANSWER.

  6. I breathe through my mouth all the time. I don’t find it difficult to breathe through my nose, I just find that I get more oxygen when breathing on through the mouth. I have never had any allergies or dental problems?

  7. My husband is always telling me “do you realize how heavy you are breathinh” I never notice this. I have a habit of breathing through my mouth as I feel like I get more oxygen into my lungs by mouth breathing. I do have asthma attacks maybe every 6 months. I know when I lend down to pick up something that drop off bed that I have to breath hard thru my mouth to get enough air into my lungs to breath. I

    • Look into Buteyko for nose breathing exercises. It was fantastic for my daughter who was also on medication for asthma since then (now a decade on) she hasn’t needed anything…hope this helps

  8. I have always wondered why my face shape is so different now than when I was a child. I have a receding jaw, overcrowded teeth, super long slim face (was short and wide as a young child), have a different shaped nose, receding small top lip, forward slanting neck position, sunken cheeks and crowded teeth . I also have super chronic gas and reflux which I developed at around 14/15 (for seemingly no reason) I also started snoring and ceasing breathing during sleep during puberty. All for apparently no reason apart from ‘reaching puberty’ or ‘getting older.’ I was a very cute child with perfect facial feature, people always told my parent to watch out because I was going to be an absolute stunner and would probably become a model later in life. The from around 13 year onwards everything switched. I was teased mercilessly for my looks and not only did my physical features transform, but my health just started going down hill for no apparent reason. I used to beg my parents as a teenager to tell me why I changed so much and begged them to pay for all sorts of plastic surgery because it was their fault. How come the negative cosmetic, physical health and even mental health problems that can never be reversed from constantly mouth breathing are not something that are made warnings to parents? Why were many doctors aware that I always mouth-breathed basically from infancy, but never told my parents that it would affect me in any way? It took me several years of research and searching to discover what had caused so many changes in me and my parents had never even known that it was a problem to breath through your mouth! It really upsets me that a lot of my problems could have been prevented, but now it’s too late unless I undergo serious, painful and expensive surgery

    • i was also bothered by huge change on my look since i was like 13. i was once a cute kid when i was below 12,everybody said that to me. Now that i just look exactly the “chronic mouth-breather profile”, i am shocked when i found out this picture, as it matches my humpback problems. All these things now finally have an answer that it’s due to the fact that i used to be a chronic mouth-breather….sigh

  9. I was surprised not to see deviated septum listed as a common cause of mouth-breathing. People can be born with a deviated septum, or it can develop following a nasal fracture or after surgery, including rhinoplasty (cosmetic surgery for the nose). The Indian practice of Ayurvedic medicine has emphasized the importance of breathing through the nose for thousands of years, and I believe it’s part of the traditional yogic practice. It’s interesting to see ourselves returning to the teachings of an earlier times, and to consider what wisdom ancient people may have known that is now lost, and must be rediscovered.

  11. Hi, thanks for this update, i have a 5 yr old chronic mouth breather who has developed the typical face of a mouther breath, he has dental cavities and has had 2 teeth removed already. He also ha GIT problems of gas and abdominal pain. My ENT surgeon plans to have him operated for enlarged adenoids. What is the likelihood that his current complications will correct?

    I will appreciate your response because i need to make this decision for surgery.

    • Hi Dennis,

      I think adenoids can shrink as you grow. Our son had large adenoids when he was small (he is now 14). Warm milk with turmeric, black pepper, cardmon powder (mostly for flavour) helped him as well. He didn’t require any surgery. You can google more on this. Hope this helps!

  12. I am 17 years old and I am mouth breather.But I started too breath through my nose.Will my face change to the better if I continue to breathe through the nose?

    • Sorry, but probably not. You’ve stopped growing by now. It would be hard to change back. It’s the reason why people try to get braces while they’re still kids—once you’re an adult, your bone structure really doesn’t change much.

    • Actually, a lot of people experience improvement in their facial structure when they change to holding their tongue on the roof of their mouth and eating a tough diet that exercises the facial muscles, it does take two or three years to notice a significant difference once you’re fully grown though. Look up the orthothropics channel on youtube. At the very least changing your breathing and tongue posture will stop your facial features from worsening as you get older, for example if you hold your tongue on the bottom of your mouth you may find your jaw widening as you age. it’s the same as never working out other parts of your body, it may be easier to get in shape when you’re young, but it’s not impossible as adult, it just takes more dedication.

  13. I really appreciate this article but can you provide some scientific citations? I am studying this in yoga teacher training class but don’t want to provide unsubstantiated data to my colleagues.

  14. Sarah;

    I am so glad you are out there doing this types of therapies.
    When we do orthopedic development of the jaw,(note) not orthodontic,
    the nasal airway improves, facial features improve, chronic pains improve.
    Many times one cannot do just orthopedic development of the jaws, if the patient is a mouth breather, they will fight the movements we make with our appliances.
    That is exactly why so many people that has had braces, have crooked teeth again in adulthood. Because the change to nasal breathing and the training of the muscles (myofunctional therapy) did not happen.

    We have crooked teeth because there is an underlying breathing disorder.
    So those of us who are involved in the orthopedic/ airway dental world need more of you to help things happen. The combination of therapies is what makes big improvements.
    TMD, chronic pain,sleep disorders and headaches are all interconnected

    After all is all about breathing!!!!

  15. It all makes sense to me now… FML!

  16. I’m 28 now and my face didn’t really develop the way I wanted it to. My voice trails off and isn’t very loud and I find myself having to repeat things to people because they can’t hear me. I can breathe through my nose but I don’t really want to go through surgery to fix it is there another way around it? I try to practice when I can to breathe through my nose if I try to do it more regularly in my calm periods of time throughout my day will it start to approve?

Ive had a lot of health problems that I didnt understand as a young teen, i always felt tired couldnt do well in school, i found it very hard to focus, socialising problems, id always be suffocating myself to keep my mouth closed in public places because it just looked so bad having my mouth open infront of people, over bite i cant keep my mouth closed naturally and recently receding gums

  19. I forgot to add that I havent been able to breath through my nose recently found out that I have a deviated septum and swollen turbinates, my parents didnt really support me i had to find answers to my health issues myself. Im 23 now and this issue has really affected my life i wish people were aware especially doctors all they seem to know is what books tell them they dont care about anything else.

  20. I am 22 now and just decided to research all this. I have really bad environmental allergies and chronic nasal congestion which had caused me to mouth breathe since I was little. Now my posture is extremely bad and I have feelings of fatigue all the time. I also wish someone would have told me about mouth breathing as a child. 🙁 I am going to school for speech pathology and the last thing I need is to be mouth breathing in front of clients. HELP!

  21. I am a mouthbreather since i was little, not sure of the cause, but im fatigued,i always talk nasally, my face is long, high smile line, bad bite, always sick, hate the appearance of my face, poor concentration, & most of all im worried about my children esp 1 who looks similar to me he is 5, im taking him to the pediatric dentist on Monday. i would really like to take action to treat my condition would love your professional opinion on where to start. i have 3 young children under 5 & havent made time to help myself. I am actually a dental hygienist myself but only work casually.
    thankyou your help would be appreciated
    God bless

  22. I have had this problem since I was baby, I’m 44 years old now, when I was young I would be upset minded with my mouth open, I was bullied at school I never performed well in school because of this, when I turned adult this behaviour continued I have slow speech and feels tired all the time, when I close my mouth I seems to be like smiling and people think I’m smiling at them that makes me open my mouth again when in public, I feel uncomfortable with my mouth open I glad to find people with this condition and for sharing their experience I hope I get over it because I did not know it is a medical condition, I thought it was just a bad habit, thanks for the help and advice.

  23. Hi hoping you can help, I am definitely a mouth breather and cannot breath at all through my right nostril (maybe about 10%) it seams to be too small to breath through. I’ve been experiencing pain in my palate for a while now. Which is getting worse and more regular. I have two lumps (checked out by many and guaranteed by all that they aren’t cancer) I am wondering if this could be caused by overcrowding. I was told 10 years ago I needed 4 teeth out b4 braces (never happened) and now at 24yrs I have all 4 wisdom teeth too.. so not a lot of room. My third main top tooth is pushed back quite far and the pain is mostly located behind it. A dentist and a doctor thought the lump could be the bone? Do you think it could? The doc was reluctant to do a ct scan to confirm.. so now I am too. My tongue tingles right under the larger bump behind the main problem tooth. And I seam to be biting my tongue which causes pain. Talking has become problematic. Can’t rest tongue. As it rests against my teeth and palate which hurts. Do you have any idea whats going on. Oh I also have a tonsil on the right side that’s about 2~3 x larger. I now brush my teeth 2 to 3 sonetimes 4 times a day as it helps. Eating help. Milk helps. I have post nasal drip heartburn and fatigue. Any advice would be great. Doc has said to make am apointment if things get worse. No follow up. Should I see a dentist. Do I need braces now? (Not want)

  24. OMG, I can’t believe I’ve never connected my “chronic pack, neck, and jaw pain” to mouth breathing!!! I don’t think I was a mouth breather as a child, but I sucked my thumb until I was about 12 years old, at which time I was put in braces by my orthodontist. I wore braces for about 3 years. When I would talk to my mom about plastic surgery (I wanted to get my bridge bump fixed, just because I hated how it looked in profile view), she would always say, “You don’t need that, you need a chin implant because you have a weak chin.” That comment always bothered me and so I began push my chin forward so I didn’t have this ugly weak chin (which I still don’t see…..I see the nose bump). Eventually it changed the position of my tongue and how my jaw closed. I’m a very self conscious person, have been told by a friend that she hates listening to me eat (even though I eat with my mouth closed) she always says I make too much noise when eating, like I guess she hears my tongue smacking/clicking inside. It really hurt my feelings because I really try to be considerate of others. After years of altering my normal patterns, I began having back pain, then neck pain, and jaw pain…..I even noticed that it has affected my vision!!! I wish I could afford to see a Myofunctional therapist to help me get my life back because it has affected my life SO horribly that I haven’t been able to work in about 7 years because of the “chronic pain” and severe fatigue from being a mouth breather! What I’ve learned from this article is not to force yourself to chnage your face to please others because I also just realized that I hated having a round, plump looking face and that I wanted it to look slimmer, which caused me to try to change how my face looked, but I just want to get my health back!!! I feel like this would be worth SO MUCH to me……like I could actually be happy and a productive citizen of the world again! I hope I can try to re-train myself so I can get my life back, but I know that sleeping is the hardest time to keep up those re-trained facial muscles. I swear, I just want to cry because I feel like I have finally found the answer to ALL my physical ailments!!! Thank you SO MUCH for this wonderful and informative article! 🙂

  25. I had been mouth breathing for some time now, not knowing there was anything wrong with it. I never noticed everyone else breathing through their noses during rest. Id wake up multiple times a night to drink water and would still wake up with a terrible taste in my mouth. I’m still re-training myself but my condition has gotten much better.

    Thanks so much for the article Sarah, it was very informative. Lol I guess I look like the chronic mouth breather picture most of the time; anyways, thanks for the article; Jesus Christ Bless you! 🙂

  27. I am an opera singer, so I was trained to breathe through my mouth as well, as you get more oxygen through the mouth. Singers usually breathe through their mouth so they can get the extra breathe needed. I’ve never suffered from allergies and never get sick. I feel that my body get a lot more oxygen if I also breathe through my mouth. Two music teachers have lived many years into their old age as healthy. Singing is very healthy and they always taught to breathe through their mouths. I think mouth breathing is bad if as a child, but as an adult I have not had any problems in many years of breathing through my mouth. I know that taking in a lot of air actually gets more air into your organs which is wonderful. All singers who take their practice seriously, are very healthy. Thanks for the post, good info.

  28. I’ve been breathing trough my mouth since a kind. Today, i jus realized i’m a mouth breather. I want to go to a doctor, but I don’t know if im too late. I only see things about children on the internet. I will turn 17 this month.. so am I too late for learning how to breath trough my nose? I hope somebody could help me

    • It’s never too late. I get great results with adult patients including middle aged and older 🙂

  29. Hi,
    when looking up info for another orthodontic issue (crowding/wisdom teeth) I came across info about breathing through the mouth. I don’t know if I did this as a kid but around the time I got braces, (14 ish). I am 22 now, so I am not sure what kind of facial and bone development changes might have occurred or how I should go about fixing them. I am trying to simply breathe with a closed mouth but it feels “weird”. :/

    • Edit: hit send before I was finished, oops! I also definitely relate to the person above who said they started breathing with their mouth slightly open because they had a “round plump face”. Same boat, and another reason I remember my manner of breathing changed around 12 or 14 years ago.

  30. Anonymous says:

    Thanks for this very helpful and enlightening post! This made me realize the reason why I look different (like the one in the picture above) from my peers. Now, I’m 17 years old. I know it might be too late but my question is, is there still a chance that my facial bone structure would be corrected after training myself to breathe through my nose again? 2 months after doing this I noticed that there are improvements on my face such as my eyes are not as droopy as before, however I really want to know if there ia still hope for me to improve my other facial characteristic such as having weak chin, etc.

  31. Michael Keating says:

    Hello my name is Michael Keating and I am 26 years old living in Ottawa, Ontario. I grew up with severe allergies that were never addressed by a physician. I sucked my two fingers since I was 5 years old and breathed through my mouth throughout all of childhood. It led me to have long face syndrome and a disfigured body. I would get bullied in high school all day long. I went in 2005 at the age of 15 to see an orthodontist who recognized I needed braces and/or surgery to fix the bite and be able to look somewhat normal again. However my mom didn’t have the money for braces so the Dentist used a retainer to make my bite normal but not address the jaw and corresponding unattractive facial features. So after about a year and a half my teeth had been moved by the retainer but I still had an open mouth with mouthbreathing and a disfigured jaw. This led me to continue to be bullied at school. I didn’t understand I had a problem with my jaw because I was only a child and my parents didn’t see the problem with my face because they loved me so much. I figured that the orthodontist fixed my problem but I still looked the same and continued to be bullied at school. I found a way to use the muscles of my head and jaw to force my jaw closed and stand up straight so that I wouldn’t be mouthbreathing and I would look normal (I did this in grade 11, 2006). I did this so well that people forgot that I used to look a different way. I continued to force jaw closed and stand up straight instead of leaning forward in a mouthbreatging posture. This led me to feeling better about myself, I went to university and graduated with a degree in biology from Carleton University for which I recieved the President’s Medal (2012). However at this point in my life because of changing my body posture and closing my jaw unnaturally for so many years I developed extreme amounts of pain in my jaw and my whole body. At this point I wanted to go back to my regular mouthbreathing posture to relieve the pain that I felt. However I had been out of the mouthbreathing posture for so long that my body had forgotten it’s proper natural position. I tried to convinvce my family and friends that I actually used to look different when I was 16 and that I needed to get back to my proper body position to relieve all of the muscle tension and pain that I felt. However nobody believed me that I actually looked different before and needed to get back to that position. I have seen countless physiotherapists who can’t quite understand why I have no bend in my neck or bend in my knees anymore. The physiotherapists mainly conclude that I must have been in a terrible car accident, however I never was. Since then I have developed glaucoma in my eyes from the pressure caused by the tension in my forcibly shut jaw. I then for the first time in my life saw an allergist who said I had sever allergies to almost everything and that I needed allergy shots. Now at the age of 26 I have found my regular body position again and feel comfortable to walk around at home looking like a mouth breather with an open mouth, however I can’t bring myself to do it when I am out in the world and not alone in my house. At the present moment I am trying to convince my father of all of this and I need to contact someone who can explain to him that I DID grow up to be disfigured only to find my own way to mask my mouthbreathing posture for the past 10 years (since 2006). I am hoping that you can help me reveal the truth to my family and friends. I can send pictures of my body both in the mouth breathing posture and in the posture that I have created to mask my disfigurement. I have also been to several dentists who see that I have a proper bite but so far no one has been able to recognize the problem with my jaw. As of now I am in a limbo forced to live and work in an unnatural body position that only causes me more pain and an array of other physical problems. Can you help?

    • Michael, have you checked your lingual frenum? Are you perhaps tongue tied? There is research now that the tongue tie can be the cause of everything you’re describing. A orofacial myofunctional therapist can help you with everything, tongue tie or not.

  34. Thank you for the information. For the person who has a child with large aidnoids, please have them removed if you have the chance. I know people who had theirs removed in their late teens because they don’t always shrink. Even if they do shrink the time wasted isn’t worth it. My daughter had hers removed when she was 2 and it was the best choice we could have made. She was literally a different child. She couldn’t sleep and when she did she’d wake covered in sweat and irritable. She was tired all day. Honestly, our ENT changed her life.

  35. I saw an article on line about nasal breathing and thought I would give it a try, I took it seriously and after looking at other information, this is what happened,

    1. I have been a nose picker all my life, within two days of nasal breathing I stopped, why? Their was nothing to pick, my nasal cavity was clear.

    2. My posture changed, I was always pushing my shoulders back to look better, I don’t do that anymore because I am naturally upright.

    3. My back is so much better, I’m 75 and getting up and down to pick things up was difficult, I had to get on my knees and struggle to get up, not now I can pick things off the floor with no trouble, also getting in and our of the car is now done without difficulty.

    4. I’m a jazz musician, I play clarinet and nasal breathing has some benefits, my tonguing has improved, I put this down to my new tongue position in the roof of my mouth where it is now, muscles can learn.

    5. If I want to sustain a long note I take a deep breath through my nose to fill my lungs, I can play much longer sustained notes than I could before, it’s normal for a wind player to breath through the mouth but I’m trying to change this old way of playing, it’s not easy but I’m convinced it will work if I continue to play that way on gigs, I think this is not known to wind players.

    That’s it, I could go on apart from two other things, my well being is better and I seem to be much calmer.

    The sad thing is when I tell other people about the benefits of nasal breathing they show little interest, my brother who has health problems completely dismissed it saying to me don’t be stupid everybody breaths through their mouth.


  36. A small addition to my previous post, I am now nasal breathing at night, much better sleep and this is true, when I wake up I’m in the same position I was when I went to sleep, I don’t seem to have moved through the night.

  40. i am a mouth breather, now only I came to know that mouth breathing causes various effects in our body and now I am experiencing everything… its very difficult for me to breath through nose…I am trining up slowly to breath from nose…lets see what happens…

  41. Hi,
    I am a 17 year old mouth breather since as long as i can remember and i have had numerous complications with my oral health. I first was diagnosed with an overbite which was eventually corrected by my orthodontist when i was around 7 years old and then had 5 years of orthodontia until age 14 . I also had enlarged tonsils and adenoids when i was younger and got both of them removed. i have also had surgery on my front lower gums to correct gum recession. Most Importantly, in addition to all these hellish health problems i developed asymmetry in my jaw (one side is 3 mm longer than the other) at a young age and my doctors have all said i must have surgery to correct this problem. I also have allergies.

    All of this mouth breathing information is very new to me and I am just now starting to connect the dots on how many of these problems may be related. However, my physicians seem to have failed to do this and it makes me really anxious to think about since i am supposed to be undergoing a very painful and expensive procedure to correct my jaw asymmetry sometime in the future.

    Please let me know which of my health problems can be attributed to mouth breathing (or causing it) and what type of doctor i can go to to discover some more comprehensive health care to correct this issue.

  42. I’m a girl and and I just turned 14. I started breathing through my mouth one month ago. Is there still hope for me, or is it too late?

  44. I have been a mouth breather all my life and I’m 35 now just starting the process of breathing through the nose instead. Believe me, breathing through the mouth as a child will eventually cause the chin and jaw line to recede and not develop or expand properly. I don’t know the exact science behind it but do suffer from the affects of just such a problem. I really hope parents out there teach their children to breathe appropriately because they don’t want to be like me and stuck with the stigma of a flattened recessed chin/jaw. Thanks.

      My child is almost 3 years old and my wife and I noticed that she breathes through her mouth about 2 months ago and we’ve asked doctors but here in Canada (BC) they all pretty much suck in terms of not caring at all for the little ones (they’d care so much more if it was their relative I’m sure). We’ve been given an appointment with a specialist but it’s nearly 2 months away and I’m afraid that by that time she will be used to this and it would be too late to get her to change that habit.

      She doesn’t sleep well and it might’ve affected her sleep since birth because she never slept more than 3 continues hours in the first 18 months. Always woke up every hour or 2 and that affected us as well but after she’s slept better (longer) without waking up a lot. She snored (still sort of does some nights) for weeks and again doctors tell us it’s normal and all the stupid things that we already know or have tried so I’m really not sure what to do at this point. I would love to know how I can help fix this issue for my beautiful daughter (everyone who sees her says she’ll be a heart breaker because she’s so beautiful and I really don’t want to have something like this change her facial features later on).

      • Hi Eddie,
        If you’d like to book a free assessment, I’d be happy to meet with you to go over the options. I have programs for younger children, so there definitely is hope. Drop me a note using the contact form on this site and we can set something up.

      • By the way she doesn’t/didn’t suck her thumb and we used the pacifier for a short period of time and she breathes ok during the day but it’s a problem when she sleeps only (night and nap times when she takes the naps which isn’t much because she’s always hyper).

  45. I m suffering from deviated septum and dust allergies from years ago…do there used to be nose blockages often…..bt as days passed things gone worse I’m berating through mouth than nose….nd from few days suffering from heart pain…so do mouth breathing effects heart too.

  46. Hi my son is mouth breather from his birth but it gets better if he has no cold or cold. If it is winter time it gets worse and he breaths almost the whole time with his mouth. We took him to our GP but the response was he will get better after he reaches age 5 or to see if something is blocking his nose a surgery.I don’t know what to do but he needs help.

  47. I’m 19 years old and suffer from “long face syndrome”- I have a recessed chin so my jaw grows downward rather than more angular. I also have quite a long nose so altogether it makes me have a very unflattering side profile. I had blocked signisis when I was young which affected my speech production and hearing- also means I was a heavy mouth breather. I had my gromits and adenoids removed to help me breath through my nose easier but out of habit I still breathe through my mouth, more in my sleep. I have the classic symptoms- I have dark circles under my eyes, chronic fatigue and numerous ear infections and dry mouth etc. I’m afraid it’s too late and my face deformations are irreversible; I had incredibly crooked and crowded teeth which I got fixed when I had braces 2 years ago but I lost my retainer and they’ve fully relapsed- as a result I have to pay 3 grand to get Invisalign. Even then my face structure will always look like this simply from not breathing through my nose. I have very low self esteem and it’s made me very introverted and anxious when around people and I’m scared I’m never going to find a partner because of my low confidence in the way I look.
