If you’ve scrolled through TikTok lately, you’ve probably seen people applying a small strip of tape over their lips before bed. The idea is simple: force yourself to breathe through your nose at night. But is it safe, and does it actually work? With millions of views and a growing list of products on the market, the mouth taping trend has outpaced the science. Here’s what the evidence—and the experts—actually say.

Is it good to tape your mouth while sleeping?

What is the purpose of mouth taping?

  • Mouth taping is the practice of placing adhesive tape over the lips before sleep to encourage nasal breathing (Sleep Foundation)
  • Proponents claim it reduces snoring, prevents dry mouth, and improves sleep quality (WebMD)

The goal is simple: close the mouth, force the nose to take over. Nasal breathing is preferred because it filters, warms, and humidifies air, and may help regulate nitric oxide levels (Cleveland Clinic). But the leap from “nasal breathing is good” to “mouth taping is safe for everyone” is where the science gets shaky.

The paradox

Mouth taping forces a behavior that is beneficial in theory, but the method introduces risks that can outweigh the benefits for many people.

Does mouth taping improve sleep quality?

The evidence is mixed. A handful of small studies suggest that nasal breathing during sleep may reduce snoring intensity, but no large randomized trials have confirmed that mouth taping improves sleep quality for the general population (Sleep Foundation). The PLOS One systematic review found that most studies on oral occlusion devices lacked rigorous controls (PLOS One).

The pattern: what works for mild snorers with clear nasal passages may not apply to the broader population. For anyone with undiagnosed sleep apnea or chronic nasal congestion, the risks climb sharply.

Do dentists recommend mouth taping?

What does the American Dental Association say?

  • The American Dental Association released a statement in 2023 saying it does not recommend mouth taping due to safety concerns (CNN)
  • Dental professionals warn that mouth taping can interfere with normal jaw position and may worsen temporomandibular joint (TMJ) issues (HealthCentral)

Mouth taping is not a dental treatment. The ADA’s position aligns with the broader medical consensus: the potential harms—skin irritation, anxiety, breathing difficulty—outweigh any unproven benefits.

Are there any dental risks?

Yes. Medical News Today notes that mouth taping can restrict airflow, cause nighttime awakenings, and in extreme cases contribute to asphyxiation (Medical News Today). For people with acid reflux, the tape can increase the risk of aspiration if vomiting occurs (Houston Methodist).

What to watch

Anyone with a history of nasal obstruction, sleep apnea, GERD, or claustrophobia should avoid mouth taping entirely. The catch is that many people don’t know they have these conditions.

The implication: mouth taping carries unknown risks for undiagnosed conditions.

Why do athletes sleep with mouth tape?

Does mouth taping improve athletic performance?

Some athletes, particularly those in endurance sports, have adopted mouth taping to promote nasal breathing during sleep, believing it improves oxygen uptake and recovery (WebMD). The theory: nasal breathing increases nitric oxide, which can improve blood flow and lung function.

But the evidence is thin. No peer-reviewed studies have directly linked nighttime mouth taping to measurable improvements in athletic performance (Medical News Today). The few testimonials are anecdotal. For elite athletes, the small potential benefit may be worth the risk, but for the average person, the trade-off is less clear.

Is there evidence for better recovery?

Not yet. The PLOS One review noted that studies on oral occlusion devices (including mouth tape) have not isolated recovery as a primary outcome (PLOS One). The implication: the buzz around athletes is more marketing than medicine.

What are the negative effects of mouth taping?

Can mouth taping cause breathing problems?

  • Yes, especially if the nose is blocked by allergies, a cold, or a deviated septum (Sleep Foundation)
  • Houston Methodist warns that mouth taping may lead to asphyxiation in people with sleep apnea, nasal obstruction, or acid reflux (Houston Methodist)
  • The PLOS One systematic review found that 4 out of 10 studies explicitly discussed the risk of serious asphyxiation when oral occlusion is combined with nasal blockage or regurgitation (PLOS One)

What are the skin reactions?

WebMD advises against using common adhesive tape because it is not breathable and can irritate skin or cause an allergic reaction (WebMD). Cleveland Clinic reports that skin redness, irritation, and blistering are common complaints (Cleveland Clinic). UHS Hospitals recommends using only a narrow piece of hypoallergenic elastic tape applied vertically to reduce skin contact (UHS Hospitals).

Are there psychological effects?

Anxiety and panic are reported side effects, especially for people who feel claustrophobic or have a fear of suffocation (Cleveland Clinic). HealthCentral notes that mouth taping can increase nighttime awakenings and reduce sleep quality for those who are anxious about the tape (HealthCentral).

How to apply mouth tape for sleeping

What type of tape is safe?

  • Use medical-grade, hypoallergenic micropore tape designed for skin (Houston Methodist)
  • Never use duct tape, packaging tape, or any non-breathable adhesive (WebMD)

How to position the tape correctly

  1. Brush your teeth and moisturize the skin around your lips with lip balm or petroleum jelly (WebMD)
  2. Cut a small strip of hypoallergenic tape, about 1–2 inches long
  3. Place the strip vertically over the center of your closed lips, not horizontally across the entire mouth (Houston Methodist)
  4. Test the tape during the day or during a nap for a few hours before overnight use (Sleep Foundation)
  5. If you can’t breathe easily through your nose, remove the tape immediately (WebMD)

How to remove tape safely

Gently peel the tape off. If it sticks, use a little water or oil to loosen the adhesive. Never yank it off, as this can damage the delicate skin around the lips (UHS Hospitals).

  • Skin irritation, allergic reactions, and blistering (Cleveland Clinic)
  • Anxiety and claustrophobia (HealthCentral)
  • Not recommended for people with sleep apnea, nasal obstruction, or GERD (Medical News Today)

Expert perspectives

Mouth taping can cause difficulty breathing, skin redness or allergic reactions, increased anxiety, and difficulty falling or staying asleep.

— Cleveland Clinic (Cleveland Clinic Health)

Mouth taping may lead to asphyxiation in people with nasal obstruction, sleep apnea, regurgitation, or acid reflux.

— Houston Methodist (Houston Methodist Blog)

If you have any form of nasal obstruction, obstructive sleep apnea, or respiratory conditions, you should not try mouth tape at night.

— HealthCentral (HealthCentral Sleep)

For the average person who breathes easily through their nose and has no underlying sleep or respiratory issues, mouth taping might offer a small reduction in snoring. But the trade-off is clear: the safety risks are real, and the evidence for broad benefit is missing. For anyone with sleep apnea, nasal congestion, acid reflux, or anxiety, the choice is straightforward—don’t do it.

Dentists have raised concerns about mouth tape safety risks, highlighting risks such as choking and breathing difficulties.

Frequently asked questions

Can mouth taping help with snoring?

It may reduce snoring in people with mild, positional snoring by encouraging nasal breathing, but it is not a treatment for sleep apnea or chronic snoring. (Sleep Foundation)

Is mouth tape safe for people with sleep apnea?

No. Medical experts warn that mouth taping can be dangerous for people with sleep apnea because it can obstruct breathing further. (Houston Methodist)

What type of mouth tape is best?

Use medical-grade, hypoallergenic micropore tape. Avoid household tape, duct tape, or any non-breathable adhesive. (WebMD)

How long does it take to get used to mouth taping?

Some people adapt within a few nights, but if you experience anxiety or difficulty breathing, stop immediately. A daytime test run is recommended first. (Sleep Foundation)

Does mouth taping improve sleep quality?

The evidence is insufficient. Small studies show mixed results, and no large trials confirm a benefit for the general population. (Medical News Today)

Can children use mouth tape?

No. Mouth taping is not recommended for children due to the risk of suffocation and the difficulty of ensuring they can breathe through their nose. (Cleveland Clinic)

Is mouth taping approved by the FDA?

Mouth tape is not FDA-approved for sleep or medical use. The FDA has not evaluated its safety or effectiveness for these purposes. (CNN)
