What is a common problem related to dry mouth?

Dry mouth, a condition characterized by a decrease in saliva production, can lead to various complications, one of the most significant being an increased risk of tooth decay. Saliva plays a crucial role in oral health; it helps neutralize acids produced by bacteria in the mouth, washes away food particles, and contains minerals that assist in the remineralization of teeth. When saliva levels are low, the mouth becomes more acidic, and the protective mechanisms are diminished. Consequently, this creates an environment conducive to the growth of bacteria and the development of cavities, making individuals with dry mouth particularly susceptible to tooth decay.

In contrast, increased saliva production would not be a concern for someone experiencing dry mouth, as the issue is fundamentally related to a decrease rather than an increase. Tooth sensitivity may occur in various dental conditions but is not a direct result of dry mouth. Mouth sores can also affect the oral cavity but are not as universally linked to dry mouth as the risk of tooth decay, which is a common and well-acknowledged issue arising from reduced salivary function.
