Dry mouth can be caused by several factors, such as medication or illness. It could also occur due to dehydration and old age, as well as certain health conditions.
Lack of saliva in the mouth can cause tooth decay, because saliva is the mouth’s natural defense against plaque, food debris, and harmful bacteria. Your dentist can provide a variety of solutions to relieve dry mouth to preserve the health of your teeth, such as medicated mouthwashes and toothpaste to promote saliva production.
