Obstructive sleep apnea patients are often treated with CPAP devices or oral appliances. Both oral appliance and CPAP patients may experience dry mouth for various reasons. The condition of dry mouth, lack of saliva, is also known as xerostomia.

Today, we will review tips and products that may help in coping with dry mouth  experienced not only during sleep time, but also residual dry mouth symptoms that occur during the day.

Man Drinking WaterMask leaks and sleeping with open mouths can contribute to dry mouth conditions in CPAP users.

Adjusting masks, changing mask types, adding chin straps or CPAP humidifiers are some of the most common solutions for relieving dry mouth in CPAP users.

Other obstructive sleep apnea patients choose to treat apnea with oral appliances. Oral appliances are professional dental sleep mouthguards that prevent the jaw and associated tissues from drifting back and blocking the airway.

Oral appliance patients may also experience dry mouth if their device allows the freedom for the lower jaw to drop open.

Some device designs have features to allow small elastics to be added that keep the mouth closed during use. Some types of oral appliances include designs that restricts any mouth openings at all.

Ask your CPAP supplier or sleep apnea dentist for guidance if the causes listed above are suspected.

In addition to the causes listed above, other reasons for dry mouth in both CPAP and oral appliance users may involve medication side effects, Sjögren’s syndrome and other medical conditions.

Your physician or dentist may evaluate your symptoms and suggest best treatment options.
