It may be one of the great nuisances of trying to use a nasal mask with continuous positive airway pressure (CPAP) therapy: mouth leak causing dry mouth in the night. What if there was an effective solution to this problem? Learn how Chin-Up strips may help to reduce oral leak with CPAP.

What Causes Dry Mouth with CPAP?

First, it is important to understand that dry mouth often occurs when using CPAP due to the mouth coming open.

This may be due to various causes. If your nose is congested due to allergies or a cold, or if you have a deviated septum, you are likely to open your mouth to breathe adequately. Treatments targeting these issues may improve dry mouth. Dryness can also occur due to lack of humidification. It is recommended that most people use a heated humidifier with heated tubing, especially if dryness in the nose or mouth is occurring. The use of saline sprays or rinses in the nose may provide additional moisture without side effects.

If air escapes from a gaping mouth or even parted lips during the night, it will lead to dryness and feeling parched. This can sometimes be quite profound: your mouth may feel as dry as a bone. This loss of air pressure may compromise the effectiveness of your CPAP therapy. If this dryness occurs repeatedly (especially on a nightly basis), it could cause other problems, such as theoretical damage to your gums or even loss of teeth.

Most people will try a chinstrap to keep the mouth closed or switch to a full-face mask. What if you need another option?

Chin-Up Strips May Improve Mouth Leak with CPAP

Chin-Up strips are used to support the chin and lower jaw to keep the mouth from coming open during sleep. They are applied much like a large, U-shaped band-aid with an adhesive surface and flexible material.

Chin-Up strips may promote nasal breathing and reduce the annoying leak of CPAP pressure from the mouth.

The U.S. Food and Drug Administration (FDA) has not approved Chin-Up strips to be used alone to treat obstructive sleep apnea. In fact, it would be dangerous to force the mouth closed if, due to nasal obstruction, you needed to be breathing through your mouth to obtain adequate oxygen and to expel carbon dioxide.

At a cost of about $16 for 30 strips, Chin-Up strips are a relatively inexpensive option if you are experiencing dry mouth with the use of your CPAP and you need another option to reduce mouth leak.

If you continue to have problems with dry mouth, consider speaking with your sleep specialist about some additional options to optimize your therapy, including exploring other mask styles.
