Should You Tape Your Mouth Shut While Sleeping?

Apr 21, 2025

In recent years, the practice of mouth taping during sleep has gained attention as a potential method to improve breathing and overall sleep quality. But what does taping your mouth actually do, and is it a safe solution for everyone?

Learn what mouth taping is, examine the potential risks and explore alternatives for enhancing your sleep and oral health.

What is mouth taping?

“Mouth taping involves placing a piece of specialized tape over your mouth before sleep,” said Scott Rosenberg, M.D., a sleep specialist and pulmonologist at Inspira Medical Group Pulmonary. “The idea behind this practice is to encourage breathing through the nose rather than the mouth.” Proponents argue that nasal breathing can improve oxygen intake, reduce snoring and help with conditions such as sleep apnea. However, this method is not recommended for most people and may pose significant risks.

Benefits of nasal breathing

One of the primary reasons people consider mouth taping is the shift from mouth breathing to nasal breathing. Here are a few potential benefits:

  • Improved breathing efficiency: Breathing through your nose helps filter, humidify and warm the air before it reaches your lungs. This practice leads to less irritation for those who suffer from allergies or live in dry climates.
  • Enhanced sleep quality: For some, nasal breathing may reduce snoring and promote a deeper, more restful sleep. Improving your sleep quality leads to feeling more refreshed in the morning.
  • Better oral health: Mouth breathing can lead to dryness in the oral cavity, which creates an environment that may foster bacterial growth and lead to issues like bad breath or gum disease. Encouraging nasal breathing could help maintain a healthier balance in the mouth.

Possible risks and considerations

While the benefits of mouth taping might seem appealing, there are risks and precautions to consider before trying it. For people with nasal obstructions due to a deviated septum, allergies or other conditions, forced nasal breathing can lead to discomfort or even panic. If you have any known respiratory issues, you should avoid mouth taping and talk to your doctor about improving your sleep quality.

The tape itself can also cause skin irritation or an allergic reaction around the mouth, and repeated use can lead to chafing or redness. Safety is another concern, especially for people with sleep disorders or those who move frequently during sleep. The tape could become a choking hazard if it comes loose or obstructs breathing.

“Scientific evidence supporting the effectiveness of mouth taping remains limited,” said Dr. Rosenberg. “Mouth taping is not recommended as a widespread solution for improving sleep or breathing.”

Alternatives to consider

There are several alternatives to mouth taping that can promote better nasal breathing and improve sleep quality. Adhesive nasal strips are a simple, non-invasive option that gently lift the sides of the nose to open nasal passages.

A humidifier can also help by adding moisture to the air to ease nasal breathing—especially in dry climates or during winter months—when indoor heating reduces humidity levels. For those struggling with nasal congestion, managing allergies through medication or natural remedies, such as saline nasal sprays, may relieve symptoms and encourage better airflow.

“Sleep position plays a crucial role in breathing,” said Dr. Rosenberg. “Adjusting your sleep posture or using specially designed pillows can help maintain an open airway, reduce snoring and improve overall sleep quality.” People with underlying conditions such as sleep apnea may benefit from talking to a sleep specialist who can offer personalized solutions and lifestyle modifications.

A good night’s sleep is a cornerstone of overall wellness, and multiple strategies can ensure you wake up feeling your best. “While mouth taping may benefit some, it also carries risks that should not be overlooked,” said Dr. Rosenberg. “Evaluating the potential pros and cons and considering safer alternatives is key to finding the right approach for better sleep.” If you’re curious about trying mouth taping, talk to a sleep specialist about safer, more effective options tailored to your needs.
