How does modern dental filling material interact with sugar, salt, pepper and food to inflame your mouth?

They Do Not: The bacteria do interact with foods to create acids that attack the teeth and cause decay and gum disease if you do not clean properly. Inflamed gums are the start of gum disease. If you are saying your entire mouth is inflamed then you need to see your md to check for allergies to food or materials.

They don't: Once set, filling materials are chemically inert and do not interact to any extent with spices in your food. The inflammation in your mouth is coming from another source.

Infection?: Infections are the major cause of jaw pain. Muscle spasm from grinding or clenching van also cause jaw pain. On rare occasions heart attacks or cancer can cause jaw symptoms. See a dentist to diagnose the source.
