How should I protect my teeth and gums if I have dry mouth (xerostomia)?

Saliva helps wash away food and balance acids in your mouth. When saliva is low, teeth have less natural protection. Cavities can develop even if you did not have many before. Dry mouth can also make dentures uncomfortable and increase the risk of mouth irritation or yeast infection.

Brush twice daily with fluoride toothpaste and a soft toothbrush. Clean between your teeth each day with floss or another tool your dentist recommends. Limit frequent sugary snacks, sweet drinks, and acidic drinks. Sipping soda or sucking on sour candy throughout the day can expose teeth to repeated sugar or acid.

Tell your dentist about your dry mouth, medicines, and any trouble keeping up with oral care. Based on your cavity risk, the dentist may suggest prescription-strength fluoride, fluoride treatments, or more frequent checks. These steps may lower cavity risk. Results vary. If you wear dentures, clean them as directed and ask about sore spots. Report tooth pain, white patches, bleeding, or mouth sores rather than waiting for your next routine visit.
