What possible issue can xerostomia lead to?

Xerostomia, or dry mouth, can lead to a variety of issues mainly due to a reduction in saliva production, which serves many critical functions in oral health. One significant consequence of xerostomia is that it increases the risk of tooth decay. Saliva plays a vital role in washing away food particles and neutralizing acids produced by bacteria in the mouth. When saliva production is decreased, this protective mechanism is impaired, leading to a higher chance of dental caries and other oral health problems.

Although retrograde salivary infection is associated with salivary gland function, it is not a direct consequence of xerostomia in the same manner as the increased risk for tooth decay. The absence of adequate saliva can lead to difficulty swallowing, sore throat, and other oral discomforts, but the most pressing and well-recognized issue remains the complicating factor of increased tooth decay, making it the primary concern in patients suffering from dry mouth. Thus, the connection between xerostomia and dental decay is critical for understanding the implications of this condition.
