Home / My Blog / Mouth Taping At Night

Mouth taping at night has become a very popular topic lately, but it’s also still controversial. A lot of people wonder why anyone would tape their mouth while they sleep, or if it’s even a safe thing to do.

Mouth taping is actually something that I suggest to a lot of my patients but it’s not necessarily for everyone, and it’s certainly not a panacea for every oral myofunctional symptom or condition. If there’s an underlying structural issue or a deeply entrenched habit, then that needs to be correctly dealt with, but mouth taping is one of the tools that I use in my practice to achieve my Four Goals of Myofunctional Therapy. And it’s a very effective tool, helping to address oral myofunctional issues and related conditions including sleep disordered breathing and sleep apnea, dry mouth and more.

In this video, I’ll go into some detail to explain what I know about taping your mouth – how to do it, why I use it myself, and why use it for the patients in my myofunctional therapy practice.

If you’d like to find out more about myofunctional therapy in general or my practice, please check out the rest of the videos on my YouTube channel.



  1. Excellent discussion on how to use a very powerful tool for testing someone’s ability to breathe through the nose vs mouth, and then to train this skill. We mention the importance of nasal breathing to all of our sleep apnea and myofunctional patients. We advise testing during the day while doing something. Only attempting at night when one can comfortably tape for at least an hour in the daytime. Unless of course one is an overachiever like yours truly and starts with the nighttime first method!

    If one is unable to achieve daytime mouth taping, then we start thinking of the possibility of a nasal obstruction and refer to an ENT for evaluation.

    Btw, we order 3M micropore tape in 12 pack boxes all the time from the Big A. It is amazing how much interest this generates. Especially when we explain how research shows that mouth taping and resulting nasal breathing at night can reduce sleep apnea events. So we have included this as part of our protocol for sleep apnea therapy using oral appliances.

    Dr. Christian Guilleminault at Stanford has discussed in detail the importance of nasal breathing as the key marker of successful treatment of airway problems in children.

    Thanks, Sarah, for bringing up this incredibly important topic.

  2. Sarah, you say in this video that you know that your tongue is at the roof of your mouth when you do mouth taping. How do you it is on the roof and not at the bottom? My daughter’s lips sometimes are closed and sometimes are apart during the night and I so through the lips and her open bit that the tongue was down. I suspect it is down when the lips are together too.
