Question: 1 / 400

What role does saliva play in maintaining oral health?

Acts as an antibacterial agent

Neutralizes acids and washes away food particles

Saliva plays a vital role in maintaining oral health by neutralizing acids and washing away food particles. The ability of saliva to wash away food debris is crucial because it helps reduce the risk of plaque buildup, which can lead to cavities and gum disease. Additionally, the neutralization of acids produced by bacteria after food intake is essential for preventing enamel erosion, thereby protecting teeth from decay.

While other functions of saliva, such as acting as an antibacterial agent or maintaining pH levels, are significant for oral health, the combined effect of washing away particles and neutralizing unwanted acids is particularly fundamental in immediate oral hygiene practices. This dual purpose is vital for preserving a healthy oral cavity by promoting a clean environment and regulating acidity levels.
