Is mouth taping safe for me?

If you're a healthy adult and air moves easily through your nose with your lips closed, mouth tape is a reasonable thing to try. The serious risks that researchers have written about mostly come down to one situation: taping the mouth when the nose can't do the work. A 2025 systematic review found that several mouth taping studies left out anyone with a blocked nose, and its authors reasoned that the people who were included would be able to keep breathing comfortably through the nose while asleep. The danger they describe is for people whose open mouth at night is caused by a blocked nose.

So the safety question is mostly about your nose and a few warning signs. If both check out, you can start slowly and see how it feels. If not, the list below explains who should talk to a doctor first.

Talk to a doctor first if you:

Never use mouth tape on children

Mouth tape is for adults only.

The two-minute nose test

Sit quietly with your lips closed and breathe only through your nose for two minutes, or use our guided nose test. If that feels easy, you're a good candidate to try. If you feel short of breath, start with a nasal strip and try the test again, or see a doctor about what's blocking your nose.

How to try it safely

1. Use tape made for skin and for the mouth, not office or duct tape.
2. Practice while awake for 15 to 20 minutes first.
3. Make sure you can easily open your mouth or peel it off.
4. Stop if you wake up short of breath, anxious, or with irritated skin.

Who mouth tape suits best

Mouth tape is the best fit for adults whose noses are clear most nights and who can pass the two-minute nose test without effort. If you often wake up with a dry mouth or bad breath, or find drool on your pillow, you may be breathing through your mouth at night, and that's the habit tape is meant to nudge. Cleveland Clinic notes that most people breathe through the mouth because air can't get through the nose, so it's worth ruling that out before you reach for tape.

It also suits people who are happy to build up slowly. In the 2022 mouth taping study, researchers used a silicone hypoallergenic tape and only enrolled people who tolerated having their mouth sealed. You can follow the same idea by practicing awake first and moving to full nights only when it feels normal. Our first-week guide lays out the steps.

Keep your expectations honest. A 2025 scoping review found little agreement in the research so far and called for more high-quality studies, though one study it covered, in people without sleep apnea, reported less snoring when mouth taping was combined with other measures.

What to do if you have a cold or allergies

Take a break from tape on any night your nose is blocked. Taping your mouth when you can't breathe well through your nose makes breathing harder, and the risks in the research center on exactly that situation. The good news is that congestion from a cold typically goes away by itself within a week, according to MedlinePlus.

While you wait, MedlinePlus suggests drinking plenty of fluids, using a humidifier or steam, rinsing with a gentle saline spray and keeping your head raised at night, since congestion is often worse lying down. If you use a decongestant nasal spray bought without a prescription, don't use it for more than three days in a row, because longer use can make stuffiness worse. For allergies, a doctor may suggest antihistamines or a steroid nasal spray. In the 2022 study, people with a blocked nose were given medication and a nasal spray by the research team before they used tape.

When your nose feels clear again, retake the nose test. If two minutes feels easy, you can go back to taping. If your nose stays blocked for weeks, or MedlinePlus's warning signs appear, such as symptoms lasting more than three weeks or discharge with a fever, see a provider.

Mouth tape and nasal strips together

Pairing the two is a sensible option if your nose feels a little tight. A nasal strip sits on the outside of your nose and helps widen the nostrils so breathing is easier, while the tape keeps your lips together. A review of nasal dilator research found they improve nasal breathing, and in a placebo-controlled trial of people with long-term nasal congestion, strips improved some measures of sleep and were well tolerated.

We haven't found a study that tested strips and mouth tape together, so treat the combination as a comfort aid rather than a proven method. Neither one treats sleep apnea. The same review found nasal dilators did not improve sleep apnea outcomes, and the sleep apnea warning signs above still mean seeing a doctor first.

Signs to stop and what they mean

Waking up short of breath or panicky usually means your nose isn't keeping up. Take the tape off and retake the nose test before trying again, perhaps with a nasal strip. If it keeps happening, talk to a doctor about what's blocking your nose.

Red or sore skin around your lips points to the adhesive. Switch to a gentler tape made for skin, or stop. The 2022 study excluded anyone allergic to mouth tape.

Nausea, vomiting or reflux in the night are reasons to skip tape. Researchers have warned that with the mouth sealed, someone who brings up stomach contents may not be able to clear them. Wait until you're well.

Tape that keeps coming off by morning is a sign to slow down. In the 2022 study, researchers treated tape that had come loose by morning as a sign the person wasn't tolerating it.

A partner noticing gasping, choking or pauses in your breathing, or feeling exhausted during the day, means it's time to see a doctor. The American Academy of Sleep Medicine lists these as warning signs of obstructive sleep apnea.
