Mouth tape for sleep
We research products from makers' specs and health sources; we do not run hands-on tests. Links to Amazon may earn us a commission at no cost to you. How this works.
- Vented mouth strips. Best for: Adults cleared by a doctor who want a backup airway. See options on Amazon
- Hypoallergenic mouth tape strips. Best for: CPAP users whose doctor suggests mouth tape. See options on Amazon
- Nasal strips. Best for: Opening a stuffy or narrow nose instead of taping. See options on Amazon
Why people try mouth tape
Mouth taping has spread on social media with claims ranging from more energy and immunity to dental health. A 2025 scoping review in the American Journal of Otolaryngology looked at those claims and found only nine relevant studies. Two found improvements in sleep apnea measures, one with tape alone and one with tape plus a jaw-advancing mouthpiece; one found no benefit in asthma.
Makers such as SomniFix say their strips promote nose breathing and reduce open-mouth snoring. Treat those as marketing claims until better studies exist.
What the research shows
| Study | What it looked at | Key finding |
|---|---|---|
| PLOS One 2025 systematic review | 10 studies, 213 patients | 2 showed improvement; potentially serious risk of harm when done without guidance |
| JCSM 2025 randomized crossover trial | 62 CPAP users who breathe through the mouth | CPAP use rose by 51.8 minutes per day with mouth tape |
| OTO Open 2026 review | Nasal blockage and 2 mouth taping studies | Nasal blockage raised apnea events by 13.78 per hour |
The reviews describe the evidence as limited and mixed, and call for more research before mouth taping is recommended.
In the 2026 OTO Open review, nasal blockage also raised the oxygen desaturation index by 7.45 events per hour. Only two mouth taping studies were available to review there; they found taping reduced apnea events in people with mild sleep apnea, but the authors said differences between studies limit how far those results can be applied. The 2025 PLOS One review screened 86 articles to find the 10 that qualified.
Who should not use mouth tape
- Anyone with a blocked or stuffy nose. The 2025 review notes asphyxiation as a potential risk when the nose is obstructed, and the 2026 review found nasal blockage itself worsens sleep apnea measures.
- People with suspected or untreated sleep apnea. Loud snoring, gasping or daytime sleepiness need a sleep evaluation, not tape. See our sleep apnea without snoring guide.
- Children. Do not tape a child's mouth.
- After alcohol or sedatives, or if you could not easily remove the tape.
- Sensitive or broken skin around the mouth.
With CPAP: the strongest evidence
The clearest benefit so far is for people on CPAP who lose air through an open mouth. In the 2025 Journal of Clinical Sleep Medicine trial, 62 patients with obstructive sleep apnea used CPAP for 30 days with silicone hypoallergenic mouth tape and 30 days without. With tape, CPAP use rose by 51.8 minutes per day, 17.6% more days reached at least 4 hours a night, and good adherence improved with an odds ratio of 4.5.
If you use CPAP and wake with a dry mouth or mask leaks, ask your sleep doctor whether mouth tape or a chin strap fits your setup.
If your doctor says it is okay
- Choose a strip made for the purpose. SomniFix describes a small breathing vent as a safety backup and a hypoallergenic medical-grade adhesive.
- Single use. SomniFix says each strip is designed for one night.
- Make sure your nose is clear before you apply it, and skip it on nights you are congested.
- Test while awake first, so you know you can breathe comfortably through your nose with your lips closed.
- Stop if you wake short of breath, anxious or with skin irritation.
Safer steps to try first
Before taping, look at why you snore or breathe through your mouth. Our anti snoring device guide matches nasal strips, nasal dilators, chin straps and mouthpieces to the cause, and our how to stop snoring naturally guide covers sleep position and other habits. A stuffy nose may need its own treatment; ask a doctor if nose breathing is hard most nights.
