As a dentist, I’m interested in trying options that may help my patients. There is some evidence that mouth taping may support healthier sleep and nasal breathing.
I’ve been trying an inexpensive mouth tape (informational- not an ad!) option that checks a few important boxes for me:
✨ Less claustrophobia-inducing than other options I’ve tried
✨ Stays in place well, even with lip balm or facial serums
✨ Removes comfortably, without pain
✨ Costs less than $0.02 per use!
Why are people interested in mouth taping?
- Nasal breathing: Encouraging nasal rather than oral breathing may be helpful for people who habitually sleep with their mouths open.
- Snoring: Small preliminary studies suggest mouth taping may reduce snoring in some people.
- Sleep apnea: One small study in people with mild obstructive sleep apnea (OSA) found a reduction in the apnea-hypopnea index (AHI), while another reported fewer oxygen desaturation events.
- Dry mouth: Keeping the mouth closed may reduce overnight oral dryness in some mouth breathers, although direct evidence for mouth taping as a treatment is limited.
But here’s the important caveat: The evidence is still limited. Studies have been small and short, and mouth taping has NOT been shown to reliably improve overnight oxygen saturation or provide broad health benefits in otherwise healthy people. It is not a substitute for proper evaluation or treatment of sleep apnea.
⚠️ Mouth taping is not appropriate for everyone. Do not tape your mouth if you have nasal obstruction or congestion that prevents comfortable nasal breathing. If you snore heavily, gasp during sleep, or experience excessive daytime sleepiness, talk with your healthcare professional about possible sleep apnea rather than trying to manage it with tape.
My take? I’m interested in the potential, and the evidence.
