DEAR DOCTOR K: My mouth and throat are always very dry. As a result, I am constantly sipping water. It's annoying and uncomfortable. Is this normal? Is there anything I can do?
DEAR READER: Dry mouth is not as common as dry eyes (something I have), but it's not uncommon. The medical term for dry mouth is xerostomia (pronounced ZE-ro-STOME-ee-uh), but I'll avoid doctor-speak and call it dry mouth. Usually, dry mouth is mild enough to be an annoyance, as it is with you. However, severe cases can cause complications. Dry mouth can rob you of your sense of taste and can make chewing slow and swallowing difficult. Also, since saliva is important for dental health, dry mouth can contribute to tooth decay and periodontal disease.
