How Do Composite Fillings Work?
Cavities, chips, and small fractures can cause much larger issues if left untreated. In the past, metal restorations called amalgam fillings (or silver fillings) served the need but left many teeth discolored and strained from the effect of the metal. Today, tooth-colored composite resins blend into the tooth structure and are chemically bonded to the tooth providing a strong, permanent restoration.
Composites serve both functional and aesthetic roles, often at the same time. For example, a cavity invading the front of a tooth along the gum line may be visible in your smile line. By gently cleaning out the soft, discolored area and replacing it with a tooth-colored filling, the tooth is restored and looks better than ever.
