why does saliva not eventually dissolve your teeth?
In: Biology
Many solids are not soluble in water. Glass, steel, plastic, wood, etc, don’t dissolve in water.
Your saliva is mostly water, and the above wouldn’t dissolve in your saliva either, and neither do teeth.
In fact, since your teeth are at risk of decaying from *acids*, your saliva mildly protects you. Saliva usually has a close to *neutral* and is often slightly *basic*, and so it will dilute, neutralise, and help wash away acids on your teeth, protecting them slightly.
