To treat a cavity the dentist removes decayed part of the tooth and then fills the hollow area of the tooth. The dentist cleans the cavity of bacteria and debris.
Compounds, often called composite resins (white fillings), usually are used on the front teeth where a natural appearance is important. Amalgam is a metal alloy sometimes placed in molars. Location and amount of the decay, insurance coverage and the dentist’s recommendation contribute the type of filling that will be used.
