Xerostomia is a common occurrence at the end of life. The goal of treatment is to lessen the severity of symptoms. Proper hydration can help improve saliva creation and release. Sugar-free chewing gum and mucosal lubricants can also reduce symptoms. A non-alcohol-based mouthwash can stimulate saliva production and maintain good oral hygiene, but an alcohol-based mouthwash such as Listerine should not be used. While petroleum jelly can be used externally for dry eye symptoms at night, it should not be used orally or for dry mouth.
