Dr Dental, Saliva and Dental Heath
We may never give much thought to our spit (saliva), but this fluid is remarkable for what it does to help protect our oral health. Saliva keeps teeth and other parts of your mouth moist and washes away bits of food. Saliva contains minerals that strengthen teeth. It includes buffering agents, that reduces the levels of acid that can decay your teeth. In addition saliva also protects against some viruses and bacteria.
