While dry mouth is caused by a lack of saliva, the concern is what may be causing it. Taking certain prescription drugs may result in dry mouth. People who receive radiation therapy to the head and neck often suffer from reduced saliva production. Other causes may be from salivary gland disease, diabetes or leukemia. To treat dry mouth, fluid intake can be increased.
Sugarless lozenges are another alternative for dry mouth.
In chronic cases, your dentist may recommend using artificial saliva. If you suffer from dry mouth, extra care needs to be taken with your teeth, as you are more susceptible to decay and infection. If you have problems with dry mouth or would like to know the cause of the problem, be sure to Ask Your Dentist.
