Dry mouth, also known as Xerostomia, is caused by not having adequate saliva flow. It is a symptom of a medical disorder or a side effect from a medication.
Saliva protects teeth from decay and keeps the hard and soft tissues healthy inside the mouth. Saliva is essential in cleansing and lubricating the mouth. It also has proteins and enzymes that flush away food and bacteria from the mouth.
Common problems associated with dry mouth include bad breath, cavities, and mouth infections. Dry mouth is very common; it affects about 1 out of 4 adults.
There are various methods to treat dry mouth. Sugar-free candy or gum will stimulate saliva flow. Your dentist may also recommend using an artificial saliva product or oral rinses.
