My dental filling and crown came off

Dental fillings are made of different materials. They can be made of plastic, porcelain or silver/gold alloy. Fillings are used to fill cavities in the teeth. Oftentimes, dental fillings either fall off or come loose due to growing decay beneath the tooth. The decay destroys the tooth, so the tooth can no longer hold the filling. When this happens, the filling and crown can no longer hold on to the tooth and may slowly come off. When you encounter a broken filling, it would be ideal to see your dentist immediately.
