White or tooth colored bonded fillings:

Traditionally, teeth requiring repair were restored with amalgam (silver colored mercury containing fillings) or gold.  Due to great advances in dental materials and techniques, esthetically and health conscious people can have a natural looking smile void of any dark unattractive fillings.  Teeth are restored with a mercury-free tooth-colored resin material that is durable and minimizes the amount of tooth that needs to be prepared, eliminating needless weakening of the tooth.  As such, these restorations account for the most common cosmetic or esthetic treatments in dentistry.
