Swish it
If you’re looking for a way to prevent dry mouth while sleeping, add mouthwash to your pre-bedtime routine. But be sure to look for the mouthwashes that are specially designed for dry mouth. These will contain xylitol, a sweet-tasting alcohol derived from some plant tissues. Examples of xylitol-containing mouthwashes include ACT Total Care Dry Mouth Rinse and Biotene Dry Mouth Oral Rinse, the first product to earn the ADA Seal of Acceptance for dry mouth. Don’t reach for ones with alcohol or peroxide though, as they can be drying.
Breathe through your nose
Train yourself to breathe through your nose, at least during the day when you have more control over it. Breathing through your mouth can dry out your mouth and nasal passages. If you are breathing through your mouth because of allergies or a cold, be sure to avoid antihistamines, which can make dry mouth worse because of their dehydrating properties. These are natural ways you can treat allergy symptoms.
Rethink your diet
Spicy or salty foods won’t necessarily make dry mouth worse, but they can cause pain in the mouth. Dry foods can also be tough to eat because of the lack of saliva in your mouth. “If you eat dry foods like crackers or potato chips, make sure you’re drinking water with them,” says Dr. Messina. If you’re experiencing pain or discomfort from these types of foods, stop eating them. Sticking to bland, moist foods at room temperature or cooler will be best for your mouth.
