Dry Mouth (xerostomin)

Dry mouth, or xerostomin is the result of decreased saliva production, which affects up to 60% of older adults. Saliva lubricates the mouth helping to prevent decay and protect tooth enamel. But don’t worry; there are plenty of ways to manage this condition.

Dry mouth can be caused by a variety of reasons, including medications you may be taking, radiation or cancer treatments, smoking, immune deficiency, systemic diseases (such as Diabetes, Parkinson’s, Sjogren syndrome) or salivary gland aplasia.
