Diabetics have a greater risk of dry mouth. Sometimes if the blood glucose levels are higher than they should be, the result is dry mouth. Or sometimes antihistamines taken for allergies or colds or other medications can result in dry mouth. Dry mouth can make it difficult to chew your food and to swallow easily. Saliva is a lubricant that contains many chemicals that bathe your teeth and protect them from acid-producing bacteria. When you have dry mouth, you have a higher chance of tooth decay and infections. You can remedy dry mouth by drinking more water or other sugar-free liquids. Try chewing sugarless gum, rinsing your mouth and spraying the mouth with special formulas to increase saliva.

Dry mouth in diabetics can be an early warning sign of gum disease, an oral health problem for which diabetics are at greater risk. Dry mouth can also be caused by a number of medications.
As the constant saliva can help in preventing tooth decay, it is important to treat dry mouth. Your dentist can recommend various methods to restore moisture. Sugar-free candy or gum stimulates saliva flow, and moisture can be replaced by using artificial saliva and oral rinses.
