The crucial role of saliva in protecting teeth, fighting bacteria, and maintaining oral health.

Saliva is one of the body's most important natural defenses for oral health. It washes away food particles, neutralizes harmful acids, provides antibacterial compounds, and supplies minerals that help repair early tooth decay through remineralization. The average person produces about 1-1.5 liters of saliva daily. Reduced saliva flow (dry mouth) significantly increases the risk of cavities and oral infections.
