What's the role of saliva in cleansing teeth?

Fluid: Saliva doesn't necessarily have a role in cleaning your teeth. It would matter if you didn't have saliva while cleaning your teeth.

Reduces cavities: Saliva keeps your mouth and teeth moist. When dry there are more cavities because there is a loss of the buffering action against the acids that occur in plaque. With adequate saliva, you can clean better and less tartar will form.
