Why is sleeping with your mouth open harmful?
Sleeping with your mouth open can cause several health issues:
- Snoring: When you sleep with your mouth open, the air you breathe in is forced through the narrow space between the soft palate and the tongue, which causes vibration and snoring.
- Sleep apnoea: Sleeping with your mouth open can worsen sleep apnoea by causing pauses in breathing during sleep.
- Dry mouth: Sleeping with your mouth open dries out the mouth, which can lead to bad breath and a higher risk of dental problems.
- Poor sleep quality: Mouth breathing can disrupt sleep quality and cause frequent awakenings and daytime fatigue.
What is mouth tape and how does it work?
Mouth tape is a simple, non-invasive method for keeping the mouth closed during sleep. It’s a type of tape designed specifically to be applied to the lips, gently keeping the mouth closed and encouraging nasal breathing instead. Nasal breathing is healthier than mouth breathing — and supports better sleep quality.
How to use mouth tape
Using mouth tape is simple and quick. Follow these steps to apply it correctly:
- Clean and dry your lips thoroughly.
- Cut a suitable piece of mouth tape.
- Place the tape gently over your closed lips and make sure it sits firmly.
Benefits of using mouth tape
Using mouth tape has several benefits:
- Improved sleep quality: keeping your mouth closed and breathing through your nose improves sleep quality.
- Less snoring: by encouraging nasal breathing, mouth tape can reduce or even prevent snoring.
- Reduced dry mouth: keeping your mouth closed reduces dry mouth and the risk of bad breath and dental problems.
- Better oral health: nasal breathing helps maintain a healthy oral environment by reducing the chance of dry mouth and tooth decay.
Find the right mouth tape
To find the right mouth tape for your needs, consider the following:
- Material: choose a tape made from a gentle, hypoallergenic material.
- Size: find a tape that suits the size and shape of your lips.
- Strength: choose a tape with the right level of adhesion, so it stays in place all night without damaging your lips.

Is mouth tape safe to use?
For most healthy adults, mouth tape is safe to use. However, some groups should avoid using it — including people with breathing issues, severe allergies or congestion, or other conditions that prevent comfortable nasal breathing. If you’re unsure whether mouth tape is right for you, consult your doctor before using it.
Alternatives to mouth tape
If mouth tape isn’t right for you, there are other ways to prevent sleeping with your mouth open:
- Nasal strips: These can help open the nasal passages and make it easier to breathe through your nose.
- Change sleep position: Sleeping on your side or stomach can help keep your mouth closed.
- Breathing exercises: Try breathing exercises before bed to train yourself to breathe through your nose.
Conclusion
Sleeping with your mouth open can lead to a range of health issues and worse sleep quality. Mouth tape is an effective and simple solution that helps you keep your mouth closed and breathe through your nose during sleep. By choosing the right mouth tape and following good practice, you can improve your sleep quality and overall well-being.
