How Is Dry Mouth Treated?

- The doctor may also prescribe an oral rinse to restore mouth moisture. If that doesn’t help, he or she may prescribe a medication that boosts saliva production called Salagen
You can also try these other steps, which may help improve saliva flow:
- Suck on sugar-free candy or chew sugar-free gum
- Drink plenty of water to help keep your mouth moist
- Brush with a fluoride toothpaste, use a fluoride rinse, and visit your dentist regularly
- Breathe through your nose, not your mouth, as much as possible
- Use a room vaporizer to add moisture to the bedroom air
- Use an over-the-counter artificial saliva substitute
