What causes dry mouth?
People get dry mouth when the glands in the mouth that make saliva are not working properly. Because of this, there might not be enough saliva to keep your mouth wet. There are several reasons why these glands (called salivary glands) might not work right.
- Side effects of some medicines. More than 400 medicines can cause the salivary glands to make less saliva. Medicines for high blood pressure and depression often cause dry mouth.
- Disease. Some diseases affect the salivary glands. Sjögren's Syndrome, HIV/AIDS, diabetes, and Parkinson's disease can all cause dry mouth.
- Radiation therapy. The salivary glands can be damaged if they are exposed to radiation during cancer treatment.
- Chemotherapy. Drugs used to treat cancer can make saliva thicker, causing the mouth to feel dry.
- Nerve damage. Injury to the head or neck can damage the nerves that tell salivary glands to make saliva.
What can I do?
- Sip water or sugarless drinks often.
- Avoid drinks with caffeine, such as coffee, tea, and some sodas. Caffeine can dry out the mouth.
- Sip water or a sugarless drink during meals. This will make chewing and swallowing easier. It may also improve the taste of food.
- Chew sugarless gum or suck on sugarless hard candy to stimulate saliva flow; citrus, cinnamon or mint-flavored candies are good choices.
- Don't use tobacco or alcohol. They dry out the mouth.
- Be aware that spicy or salty foods may cause pain in a dry mouth.
- Use a humidifier at night.
Tips for keeping your teeth healthy
Remember, if you have dry mouth, you need to be extra careful to keep your teeth healthy. Make sure you:
- Gently brush your teeth at least twice a day.
- Floss your teeth every day.
- Use toothpaste with fluoride in it. Most toothpastes sold at grocery and drug stores have fluoride in them.
- Avoid sticky, sugary foods. If you do eat them, brush immediately afterwards.
- Visit your dentist for a check-up at least twice a year. Your dentist might give you a special fluoride solution that you can rinse with to help keep your teeth healthy.
