What is the role of saliva in maintaining oral health?

Saliva plays a vital role in maintaining oral health through several key functions encapsulated in the correct choice. One of its primary roles is to help buffer acids produced by bacteria in the mouth, which helps neutralize pH levels and protect tooth enamel from demineralization that can lead to cavities. Additionally, saliva is rich in minerals such as calcium and phosphate, which are important for the remineralization of enamel and the repair of early carious lesions.

Furthermore, saliva aids in the mechanical action of washing away food particles and debris after eating, which minimizes the risk of plaque formation and bacterial growth. By promoting a cleaner oral environment and providing essential minerals, saliva supports overall dental health and helps maintain a balanced oral microbiome. Through these functions, saliva is crucial in preventing dental issues and promoting oral hygiene.
