How Do You Prevent Your Mouth From Drying Out While You Sleep?

Brushing the teeth before bed with fluoride toothpaste, using a vaporizer in the bedroom and breathing through the nose instead of the mouth are all ways to prevent a dry mouth when sleeping, according to WebMD. Buying an over-the-counter saliva substitute may also help.

There are a number of causes of dry mouth, many of which can be prevented, states WebMD. For instance, switching toothpaste may help to ease the symptoms. Another option is to change sleeping habits. Those who sleep with their mouth closed have fewer complaints about dry mouth than those who sleep with their mouth open. Chewing sugar-free gum and sucking on sugar-free candy may also help to ease dry mouth before bed.

If simple changes at home don't work for dry mouth at night, patients should speak with a dentist or doctor about other solutions, advises WebMD. A medical professional may be able to prescribe special mouthwash or medications that can help clear up dry mouth. If dry mouth is caused by other medications, the doctor may adjust the dose or switch the patient to medications that do not cause dry mouth. Dry mouth may also be treated by following proper dental hygiene, including regular visits to a dentist.
