Composite Fillings in Dentistry at University
Cavities and small fractures can cause much larger issues if left untreated. In the past, metal restorations called amalgam fillings (or silver fillings) served a need but left many teeth discolored and strained from the wedging 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.
Composites contain a mix of liquid resin embedded with finely ground glass particles. After being molded to the prepared tooth structure, a blue light applied directly to the composite hardens the filling material within seconds. Once it’s shaped and polished to a high shine, the restoration is complete.
