For most people, there is no good evidence that taping your mouth shut improves sleep. A 2025 systematic review found only small gains in a few people with mild sleep apnea, and a real risk of harm if your nose is blocked.1
The review pooled 10 small studies with about 213 people.1 Only two found lower apnea or oxygen-dip scores, both in people with mild sleep apnea who habitually breathe through their mouths. A 2024 JAMA Otolaryngology study found that closing the mouth reduced airflow in some people with sleep apnea.2
Our take: If you snore loudly, gasp at night or feel sleepy during the day, get a sleep test before you tape anything. If you are a healthy adult with a clear nose and want to try it, use porous, vented or around-the-lip tape, test it while awake first, and stop if it does not clearly help within two weeks. Never tape a child's mouth.
Evidence grade: C for snoring and mild sleep apnea. D for sleep quality, dental and performance claims. Evidence reviewed November 2026.

| What it is | Porous tape or strips worn over or around the lips at night to encourage nose breathing |
|---|---|
| Best evidence | A 2025 systematic review of 10 small studies, only one randomized. Results were weak and mixed.1 |
| Might help | Snoring in habitual mouth-breathers with a clear nose (grade C) |

| Cost | Under $0.05 a night (3M Micropore) to about $0.87 a night (branded strips) |
| Try first | Treating nasal congestion, side sleeping, nasal strips or a dilator, and a sleep test if you snore |
| Official position | We found no AASM guideline. An AASM spokesperson called mouth taping potentially "extremely dangerous."4 |
Who should not tape their mouth
Do not tape your mouth if any of these apply to you.
- Children and teens. Mouth taping in children has not been studied.5 The 2025 review included no pediatric data.1 Some brands sell kids' sizes.6 We do not recommend them.
- Any nasal blockage. This includes a cold, allergies, sinus infection, a deviated septum, nasal polyps, or enlarged tonsils or adenoids. Four studies in the 2025 review raised concerns about suffocation or regurgitation, mostly in people with nasal obstruction.1, 3
- Known or suspected sleep apnea, unless a sleep clinician directs it. Warning signs include loud snoring with gasping or choking, pauses in breathing that someone else notices, and daytime sleepiness. Taping can delay a diagnosis.7, 8
- Moderate or severe sleep apnea. Closing the mouth cut airflow by about 40% in some people with more severe obstruction.2 Use CPAP or an oral appliance instead.3
- Alcohol, sedatives or sleeping pills that night, or nausea, reflux or any risk of vomiting. The review flagged regurgitation as a concern.1 Avoiding tape after alcohol or sedatives is our own precaution, not a tested finding.
- Heart problems3, or uncontrolled asthma, COPD or other lung disease. Ask your doctor first.
- Anxiety or panic when your breathing feels restricted.
- Anyone who cannot remove the tape quickly without help.
Where to get mouth tape
Before you buy, do the nose check in how to try it safely. If you cannot breathe comfortably through your nose for 15 minutes, do not buy tape. Look at the alternatives instead.
- Cheapest way to test it: 3M Micropore paper tape. Porous and latex-free. Cut a small vertical strip rather than sealing the lips.
- Most cautious design: Myotape. It sits around the lips and leaves the center open, so your mouth can still open.9
- Vented strip: SomniFix. Woven-mesh vent and the most adhesive safety documentation of the strips we looked at.10
- Beards: Hostage Tape. Fabric strip with a mesh section and a beard-specific version.11

Evidence map: what mouth tape does and does not do
Grades: A means consistent randomized trials or meta-analysis. B means at least one adequate controlled trial. C means small pilot or uncontrolled studies with mixed or narrow results. D means mechanism, association, self-report or brand data only. X means evidence of harm, or not suitable for that group.
| Claim | What the research shows | Grade |
|---|---|---|
| Better sleep quality | No independent studies. Only brand surveys.1, 12 | D |
| Less snoring | Two small uncontrolled studies in mild sleep apnea mouth-breathers found less snoring. No randomized trial.13, 14 | C |
| Treats mild sleep apnea | Apnea scores fell in two small studies but not in others. A sedated-sleep trial found airflow got worse in some people.1, 13, 2 | Cmixed |
| Treats moderate or severe sleep apnea | Not supported. It may worsen airflow. Use CPAP or an oral appliance.2, 3 | X |
| Reduces mouth leak with CPAP | Small studies show less leak, but only as a clinician-supervised add-on.1 | C |
| Higher blood oxygen | Average oxygen did not change with taping. The lowest dips improved slightly in one study.13 | D |
| Less dry mouth or bad breath | Mouth breathing made the mouth more acidic during sleep in a 10-person study. Taping itself was not tested.15 | D |
| Fewer cavities or less gum disease | No taping studies.12, 15 | D |
| Jawline or face shape | No evidence. Never in children.8, 5 | DX for children |
| Athletic performance or recovery | No studies of overnight taping. Brief awake studies show a small blood pressure effect of nose breathing.16 | D |
| Nitric oxide boost | Nose breathing does carry nitric oxide from the sinuses (small 1996 study). No proof it improves outcomes when you tape at night.17 | Mechanism B, outcome D |
| Nasal strips for snoring or sleep apnea | A meta-analysis found no improvement in apnea or snoring scores in sleep apnea. Internal dilators did slightly better.18 | Cno effect on sleep apnea |
Key studies
The 2025 PLOS One systematic review
Researchers searched medical databases from February 1999 to February 2024. They screened 120 records and included 10 studies with 213 patients.1* Only one study was randomized. Participants were aged 38 to 64, and no children were included.
Two studies found lower apnea or oxygen-dip scores, both in people with mild sleep apnea. The others found no difference. Four studies raised concerns about suffocation or regurgitation, especially with a blocked nose. The authors concluded: "The existing data does not support mouth taping or oral occlusion as a sound clinical intervention." They also warned of "a potentially serious risk of harm for individuals indiscriminately practicing this trend."1
A separate 2025 scoping review of 9 studies reached a similar view. It found most social media claims about mouth tape, such as better oral health and sleep quality, were not supported. Only 20% of the 50 TikTok videos it reviewed mentioned any risks.12
The 2024 JAMA Otolaryngology airflow study
This nonrandomized trial measured airflow in 54 people with sleep apnea (median apnea score 26.9) while they were sedated with propofol. Closing the mouth improved airflow in mild mouth-breathers. But in people who relied heavily on mouth breathing because their soft palate was blocked, closing the mouth cut ventilation by about 40%.2 In other words, the people most likely to want tape may be the ones it helps least.
The small mild sleep apnea studies
- Lee 2022 (20 people, no control group). Mouth-breathers with mild sleep apnea wore silicone tape. The median apnea score fell from 8.3 to 4.7, and the snoring index fell from 303.8 to 121.1. The lowest oxygen level rose from 82.5% to 87%, but average oxygen did not change. Thirteen of 20 people responded.13
- Huang and Young 2015 (pilot, reported as 30 people). People with mild sleep apnea and mouth breathing used a porous oral patch. The apnea score fell from 12 to 7.8 per hour, and snoring dropped.1, 14
- Null results. In other studies in the review, tape alone did not change apnea scores, and a randomized, blinded trial of nasal spray plus tape found no difference in apnea scores.1
Brand-run studies count as grade D at most. Hostage Tape cites a 3-week study it ran with a sleep app, based on self-reported results.11 SomniFix cites a "Harvard Medical School study," but we could not find a published, peer-reviewed version.10 A trial of silicone mouth tape for snoring and mild sleep apnea is registered (NCT06587256), but its status and results are unknown to us.19
How to try mouth taping safely
Only try this if nothing in the who should not tape list applies to you.
- Do the nose check. Close your mouth and breathe only through your nose for 5 minutes sitting up, then 10 minutes lying down. If you feel any air hunger, stop. Tape is not for you.
- Patch-test the adhesive. Put a small piece on your skin for a few hours before using it on your lips.
- Try it awake first. Wear it for 20 to 30 minutes during the day.
- Use the right tape. Choose porous, skin-safe tape or an around-the-lip design. Never use duct, masking or plastic tape.
- Do not seal your mouth fully. Use a small vertical strip, a vented strip or an around-the-lip design. Fold over a tab so you can pull it off fast.
- Help a borderline nose. If your nose is only partly clear, add a nasal strip or dilator, or skip taping that night.
- Track it for two weeks. Use a snoring app or ask a partner. If nothing changes, stop.
- Know the red flags. Gasping, morning headaches, daytime sleepiness or worse sleep mean you should stop and see a doctor.
Alternatives to mouth tape
Chronic mouth breathing is usually a sign of something else, such as a blocked nose or sleep apnea.8 These options deal with the cause.
Nasal strips and dilators
External strips such as Breathe Right are drug-free and open the nasal valve.20 Reusable dilators such as Intake use a magnetic band with adhesive tabs.21 They can help a stuffy nose and can be used alongside tape. A meta-analysis found that nasal dilators do not treat sleep apnea, though internal dilators did slightly better than strips.18
Treat nasal congestion
Saline rinses can help clear your nose. If congestion is ongoing, ask a clinician about a steroid nasal spray. Side sleeping, not drinking alcohol close to bedtime, and losing weight if you need to are other low-risk steps.
See a sleep doctor for snoring or apnea
Loud snoring can be a symptom of sleep apnea, and taping can delay a diagnosis.7, 8 A sleep doctor can arrange a home sleep test. If you have sleep apnea, CPAP or an oral appliance is the treatment to discuss, not tape.3

Myths vs evidence
| Myth | What the evidence says |
|---|---|
| "Mouth breathing is always bad." | It is usually a symptom of something else, such as congestion or sleep apnea. Fix the cause first.8 |
| "Tape fixes sleep apnea." | Not supported. It may worsen airflow in some people.1, 2 |
| "Nose breathing raises your oxygen 10%." | That figure comes from a 1996 study of 8 people who were awake.17 Taping did not change average overnight oxygen.13 |
| "Mouth tape improves sleep for everyone." | Only brand surveys say so. Independent reviews do not support it.1, 12 |
| "It will reshape your jaw." | There is no evidence for this in adults. Never try it on children.8, 5 |
| "Celebrities use it, so it's safe." | Endorsements are not evidence.1, 8 |
| "Any tape works." | Duct, masking and plastic tape are unsafe. Use porous medical tape or a product made for this. |
Frequently asked questions
Is mouth taping safe?
It can be risky. The 2025 systematic review warned of a potentially serious risk of harm, especially if your nose is blocked.1 Physicians at the Cleveland Clinic, OHSU, Emory and Duke have warned that the benefits are modest and the risks are real.3, 7, 8 If you are a healthy adult with a clear nose, follow the steps in how to try it safely.
Can mouth tape stop snoring?
It might reduce snoring in people who habitually breathe through their mouths and have a clear nose. The evidence comes from two small studies without control groups.13, 14 Loud snoring can also be a sign of sleep apnea, so get checked if you also gasp at night or feel sleepy during the day.
Can I tape my mouth if I have sleep apnea or use CPAP?
Not on your own. Tape is not a substitute for CPAP or an oral appliance.3 Some CPAP users have used mouth closure to reduce air leaks, but only under a clinician's supervision.1
Is mouth taping safe for kids?
No. It has not been studied in children and should not be tried.5 We do not recommend any kids' mouth tape.
What tape should I use? Can I use 3M tape or duct tape?
Use porous, skin-safe tape such as 3M Micropore, a vented strip, or an around-the-lip design. Never use duct tape, masking tape or plastic tape.
What if my nose gets blocked at night?
Do not tape on any night your nose feels blocked, including during a cold or allergy flare.1, 3 Use a design that leaves your mouth able to open, and fold a tab so you can pull the tape off fast.
Does the FDA regulate mouth tape?
We could not find any FDA clearance for mouth tape. Some breathing products say they are "FDA registered," which is not the same as being cleared.21 There are also no official clinical guidelines for mouth taping.5
