We all know it plays a role in digestion. The breakdown of food begins with enzymes in your saliva.
BUT...
Saliva is also a type of defense for your teeth. Did you know that saliva provides physical, chemical, & anti-bacterial protection from tooth decay?
The Defenses
- The Cleansing Effect: this is the physical defense against plaque and food particles. Salivary fluid dilutes and removes acidic components from dental plaque.
- Remineralization: saliva contains certain chemicals (e.g., calcium, phosphates & fluoride) which re-build minor damages to tooth surfaces.
- The Antibodies: immunoglobins found in saliva fight against cariogenic (cavity forming) bacteria in your mouth. But remember... once bacterial levels increase drastically in number the immunoglobins in your saliva are no longer strong enough to fight them alone.
