Dry Mouth

Xerostomia (dry mouth) is the sensation you may feel when you don’t have enough saliva (spit). The salivary glands in your mouth produce saliva to lubricate your mouth and help keep it clean.

Occasional dry mouth is normal. For instance, your mouth gets dry when you’re dehydrated. But chronic dry mouth (when your mouth is dry all the time) could point to an underlying health condition. Most often, xerostomia is a side effect of certain medications, including antihistamines, decongestants and some antidepressants.

How common is xerostomia (dry mouth)?

Dry mouth is common, affecting about 1 in 5 people. Your risk for dry mouth increases with age.
