In short
- Mouth tape only makes sense if you can breathe comfortably through your nose. If you can't, the nose comes first.
- Signs of sleep apnea, such as loud snoring, gasping or breathing that stops and starts, mean seeing a doctor before taping.
- Sleep Foundation says people with asthma or COPD should only tape if a doctor advises it, and that children shouldn't try it.
- Panic under the tape, a risk of vomiting in your sleep, or a skin reaction are all reasons to stop, at least for now.
- Many of these signs are temporary. Once a cold clears or a doctor gives the all-clear, you can come back to it.
Mouth tape suits plenty of adults, but it isn't the right move for everyone right now. If you can't breathe easily through your nose, have signs of sleep apnea, or panic with the tape on, it's better to wait and sort that out first. Most of these signs aren't permanent, and the list below says what to do about each one.
Why is it worth checking first?
Research: limited (what this means)Checking first matters because the research on mouth taping is promising but small. In a 2022 study in Healthcare, 13 of 20 adults who breathed through their mouths at night and had mild sleep apnea cut their snoring by at least half after a week of taping. But a 2025 review in PLOS One found just 10 studies with 213 patients in total, and noted that many of them excluded anyone with nasal obstruction. The authors warned of a potentially serious risk of harm for people who tape without thinking about whether it suits them.
Sleep Foundation also points out that there are no official guidelines for mouth taping yet, and suggests talking to your doctor before you try it. So the people who did well in studies were mostly people who had already passed some checks. These eight signs are the main ones to look for, grouped by what's behind them.
Your nose isn't ready
You can't breathe comfortably through your nose
Not being able to breathe comfortably through your nose is the biggest sign mouth tape isn't for you. With tape on, your nose is your only airway, so it needs to be up to the job. A clinical trial of silicone mouth tape (NCT06587256) only accepts people who can breathe through their nose with the tape in place for at least 3 minutes. Try it yourself with our nose test.
If it feels like hard work, that's not the end of the road. A nasal strip helps some people, and a doctor can look for causes such as allergies or a deviated septum.
Your nose is blocked right now
A cold, hay fever or a sinus infection can block a nose that's usually fine. Sleep Foundation advises against taping when your nose is blocked by allergies, a cold or structural issues, and Cleveland Clinic lists nasal congestion and sinus infections among the reasons never to use it. This one really is temporary. Skip the tape, and pick it up again once you can breathe freely.
Something in your airway is in the way
Cleveland Clinic says you should never use mouth tape if you have enlarged tonsils or a deviated septum, along with nasal obstruction and chronic allergies. The NCT06587256 trial also excludes people with large tonsils and people who've had surgery on the palate or tongue. If you've been told your tonsils are big, or one side of your nose is always blocked, ask a doctor before trying tape.
Your health needs a doctor's view first
You have signs of sleep apnea
The National Heart, Lung, and Blood Institute lists breathing that starts and stops, frequent loud snoring and gasping for air as symptoms of sleep apnea during sleep, and daytime sleepiness, headaches and dry mouth as ones you might notice yourself. Sleep Foundation says people with sleep apnea who aren't using CPAP shouldn't use mouth tape, and that trying it instead of seeing a doctor could delay important treatment.
One more thing to watch for if you already tape. In a 2022 study in Sleep and Breathing, researchers filmed people sleeping with their mouths taped and found that patients with sleep apnea showed "mouth puffing", and that this puffing was linked to measures of apnea. If a partner sees you puffing your cheeks under the tape, mention it to a doctor. Mouth tape isn't a treatment for sleep apnea. Our guide to sleep apnea warning signs explains more.
You have a lung or heart condition
Sleep Foundation says people with asthma or COPD shouldn't tape unless a doctor advises it, and Cleveland Clinic lists heart issues among the reasons not to. The NCT06587256 trial excludes people with chronic lung disease. In a 2009 study of 50 adults with asthma, taping at night didn't change asthma control either way, so there's no particular reason to rush.
The tape doesn't suit you yet
The tape makes you panic
Feeling a little odd on the first night is normal. Real panic is different. Sleep Foundation lists anxious awakenings as a side effect, especially for people prone to claustrophobia, and says people with anxiety or panic disorders shouldn't use mouth tape. If you try short daytime sessions and still feel panicky, it's fine to stop. Our guide to mouth taping anxiety has gentler ways in, and some people simply prefer a nasal strip on its own.
You could be sick in the night
Sleep Foundation lists anyone at risk of vomiting during sleep, because tape could get in the way of clearing your mouth. Think of a stomach bug, or a night when you feel queasy. Skip the tape until you're well. If reflux is a regular issue for you, read mouth tape and acid reflux first.
Your skin reacts to the tape
Cleveland Clinic lists redness, irritation and allergic reactions on the lips and skin among the risks. The 2022 Healthcare study left out anyone with an allergy to mouth tape. If your skin gets sore, give it a few nights off. 3M notes that what looks like a tape allergy is sometimes irritation, so a different tape or gentler removal may solve it. If a reaction keeps coming back, the AAD says a dermatologist may suggest patch testing to find the cause. Our guide to mouth tape skin irritation explains the difference.
Can children use mouth tape?
No, mouth tape is for adults. Sleep Foundation says mouth taping in children hasn't been studied and shouldn't be tried, and suggests a doctor's visit for any child who mostly breathes through their mouth, noting that mouth breathing may slow growth in children.
Pregnancy is another time to ask first. The NCT06587256 trial doesn't enroll pregnant people, so if you're pregnant, check with your midwife or doctor before you start. See mouth breathing in children for more.
What should you do if you're not ready yet?
If you're not ready for mouth tape yet, waiting isn't failing. Most of the signs above have a clear next step:
- A blocked or narrow nose: treat the cause, try a nasal strip, and retest with the nose test.
- Signs of sleep apnea, or a lung or heart condition: see a doctor, and ask directly whether mouth tape is OK for you.
- Panic: go back to short daytime sessions, or set tape aside for now.
- A skin reaction: give your skin a rest, then try a gentler tape or removal method.
If you already use CPAP, Sleep Foundation notes that mouth taping may help reduce mask leaks caused by mouth breathing, which is a good question for your sleep doctor rather than something to try alone.
Sleep Foundation suggests side sleeping and treating allergies as alternatives for snoring and nasal breathing, and notes that some studies of nasal strips found less snoring. Clear the thing in the way, whether that's a cold, a doctor's appointment or a few more weeks of daytime practice, and then come back to tape if you still want to.
Check this first. Skip mouth tape and see a doctor if you snore loudly, wake up gasping, have been told you stop breathing in your sleep, or can't breathe comfortably through your nose. More on safety

Common questions
Who should not use mouth tape?
Sleep Foundation lists people with untreated sleep apnea, anyone with a blocked nose, people with asthma or COPD unless a doctor advises it, children, people with anxiety or panic disorders, and anyone at risk of vomiting during sleep. Cleveland Clinic adds enlarged tonsils, a deviated septum, sinus infections and heart issues.
Can I mouth tape if I have sleep apnea?
Talk to your doctor first. Sleep Foundation says people with sleep apnea who aren't using CPAP shouldn't use mouth tape, and mouth tape isn't a treatment for sleep apnea. Some people on CPAP use tape for mouth leaks, but that's a conversation to have with your sleep doctor.
Can I use mouth tape with a stuffy nose?
No. Sleep Foundation advises against taping when your nose is blocked by allergies, a cold or structural issues. Wait until you can breathe comfortably through your nose with your mouth closed.
Is it OK to stop mouth taping if I don't like it?
Yes. Some people never feel comfortable with tape, and that's fine. A nasal strip, side sleeping or treating allergies may suit you better, and you can always try tape again later.
What if my skin reacts to mouth tape?
Stop and let your skin settle. 3M notes that what looks like a tape allergy is sometimes irritation instead. If a reaction keeps coming back, a dermatologist can help work out the cause, sometimes with patch testing.
Can children use mouth tape?
No. Sleep Foundation says mouth taping in children hasn't been studied and shouldn't be tried. A child who mostly breathes through their mouth should see a doctor.
