Role of Saliva In Periodontal Health & Disease - A Review.

Saliva is essential for maintaining the protection and normal functioning of the masticatory system. A 'dry mouth' or xerostomia resulting from a perceived reduction in salivary flow may lead to numerous signs and symptoms of oral dysfunction. The quality of life for affected people may be poor. Many of these persons are taking multiple medications that cause a reduced salivary flow, and the number of people taking such drugs can be expected to increase. The ingestion of softer cariogenic foods, and acidic foods and beverages in attempts to stimulate an increased saliva flow, is disastrous for the teeth.
