Dry Mouth and Excessive Thirst

Thanks for using this guide -- we hope it was helpful and that your mouth dryness or thirst improves soon.

Just remember:

- Dryness of the mouth is common, especially among persons as they age; however, age alone is frequently not the only reason and other causes are often quite treatable or reversible

- Consider medications as a potential cause of dry mouth or excessive thirst; check with your doctor or pharmacist about this possibility

- Treatment for dry mouth usually starts with simple things: searching for a reversible cause (such as certain medications), taking frequent sips of water or ice, using a humidifier where you live or work, and using a fluoride toothpaste and rinse to prevent cavities (which are more common in people with significantly reduced saliva)
