Sleep mouth tape, often called mouth taping or sleep tape, works by supporting a gentle lip seal during sleep. This encourages nasal breathing instead of mouth breathing, helping breathing feel calmer and reducing dry mouth linked to open mouth sleep.
Start with clean, dry lips and remove the backing.
Close your lips and place the tape across the centre of the lips on the outside.
Press firmly for 10 to 15 seconds to activate the adhesive.
Mouth tape works externally by supporting a gentle lip seal during sleep. This helps reduce open mouth breathing, which is a common reason airflow bypasses the nose at night.
When the mouth opens during sleep, airflow can become drier and less stable. By supporting closed mouth sleeping, mouth tape encourages air to move through the nose instead.
Sleep mouth tape is placed across closed lips before bed, providing light external support that helps keep the lips together during sleep.
When the lips remain closed, you are less likely to mouth breathe during sleep. This can help reduce waking with dry mouth and may reduce snoring linked to open mouth sleeping.
Mouth tape works through simple mechanical support and does not contain medication or alter natural sleep cycles.
Mouth breathing at night is more common than you think, and it can quietly affect sleep quality and morning energy.
Around 61% of adults mouth breathe during sleep, particularly when nasal breathing feels restricted. This is commonly associated with snoring, dry mouth, and disrupted sleep.
During nasal breathing, around 60–70% of inhaled nitric oxide is produced in the nose.
Nasal breathing can be up to 20% more efficient than mouth breathing under resting conditions, such as sleep.

Mouth breathing during sleep can increase airway dryness and airflow turbulence, which are commonly linked to snoring and broken sleep. Nasal breathing encourages airflow through a narrower, more stable pathway, helping breathing feel smoother and sleep feel more continuous.
Nasal congestion often becomes more noticeable when lying down. Allergies, inflammation, or structural narrowing of the nose can restrict airflow during sleep. Supporting nasal breathing helps airflow move through the nasal passages with less resistance overnight.
Breathing through the nose naturally slows and regulates airflow during rest. More stable breathing rhythms during sleep are associated with fewer disruptions and can influence how rested and focused you feel the next day.
Nasal breathing promotes a natural tongue position and balanced engagement of facial muscles during sleep. Over time, consistent nasal breathing is often discussed in relation to overall airway comfort and sleep quality.
A quick step by step guide showing how to apply ProActive Sleep Mouth Tape correctly.
Mouth tape is designed to be worn during sleep. It should only be used when you can breathe comfortably through your nose and when applied as directed.
No. Mouth tape is designed for single use only. For consistent hold and comfort, a new tape should be used each night.
Mouth tape is designed to last for one continuous period of use, typically overnight, often up to 12 hours.
Start with clean, dry lips. Close your lips, place the tape across the lips externally, and press firmly for several seconds to activate the adhesive.
Peel the tape off slowly from each side. Using warm water can help loosen the adhesive and make removal more comfortable.
Mouth taping is not suitable for everyone. It should not be used if you have untreated sleep apnoea, chronic nasal congestion, nasal obstruction, or difficulty breathing through your nose. If you are unsure, speak with a clinician first.
Mouth tape is not a treatment for sleep apnoea. If you suspect sleep apnoea, seek medical assessment and evidence based treatment.
If mouth breathing is driven by nasal congestion, addressing nasal airflow, for example with nasal breathing support tools, may be more appropriate than sealing the mouth. A clinician can help identify the best approach for you.
