Your saliva takes care of acids in the mouth that erode your teeth. It also helps restore tooth enamel. However, if you have a dry mouth caused by a side effect of a drug or a health condition, the acids stick around longer, causing more damage to your teeth.

Dry mouth can be an uncomfortable and even harmful condition. Here are some tips to help you treat it at home:

1. Drink plenty of water throughout the day to keep your mouth hydrated.
2. Chew sugar-free gum or suck on sugar-free candies to stimulate saliva production.
3. Avoid drinks that can cause dehydration, such as alcohol, coffee, and tea.
4. Use a humidifier at night to keep the air in your bedroom moist.
5. Avoid tobacco products, which can worsen dry mouth symptoms.
6. Brush and floss your teeth regularly to prevent tooth decay.
7. Consider using over-the-counter saliva substitutes or mouthwashes.

Remember, if your dry mouth persists or is caused by a medication, be sure to talk to your doctor or dentist for further treatment options.
