What role does saliva play in oral health?

Saliva plays a critical role in oral health beyond just a digestive fluid or a facilitator of taste. It is essential for the process of remineralization, which is the restoration of minerals to tooth enamel that may have been lost through demineralization, often caused by acidic foods and bacteria. Saliva contains minerals such as calcium and phosphate, which are integral to this restorative process. Additionally, saliva has buffering capabilities that help neutralize acids in the mouth, thereby reducing the risk of dental erosion and decay.

Furthermore, saliva also has antimicrobial properties, providing a first line of defense against oral pathogens and contributing to overall oral hygiene. Thus, acknowledging the multifaceted roles of saliva, especially in mineral supply and acid buffering, underscores its importance in maintaining oral health.
