Tooth decay and small fractures can often result in causing big problems when they are left untreated. It was years back when metal restorations called amalgam fillings (or silver fillings) served the need, left teeth discolored and strained due to the wedge effect of the metal. However, today we have tooth-colored composite resins mix that is provided with the tooth structure and chemically bond to the tooth that works the best for providing a strong, permanent restoration.
The composites include a mixture of liquid resin deposited with finely ground glass particles. After being molded to the prepared tooth structure, blue light is applied directly to harden the filling material within a few seconds. Once it is shaped and polished, the restoration process is completed.
