The average person produces 25,000 quarts of saliva (spit) in a lifetime. That is enough saliva to fill 2 swimming pools. Yet many people suffer from dry mouth. Many things including aging, medication, and radiation to head and neck can cause dry mouth. Dry mouth is annoying but can also lead to an increase in dental decay. Although there is no real cure for dry mouth, we offer for sale at our office, Salese with Xyitol, long lasting soft lozenges. These help alleviate your dry mouth and help you fight tooth decay.
