Dental Fillings

A cavity (caused by a disease called caries) happens when bacteria in the mouth produce acids that attack your teeth. In time, this acid can dissolve away the enamel on your teeth and cause a hole, which is known as a cavity. Unlike some other diseases or injuries, a cavity will not heal by itself, but if the early signs of dental decay are promptly treated before a cavity forms, it can be stopped and even reversed by your dentist.



Composite is a mixture of acrylic resin and powdered glass-like particles that produce a tooth-coloured filling. This type of material may be self-hardening or may be hardened by exposure to blue light. Composite is used for fillings, inlays and veneers. Sometimes it is used to replace a portion of a broken or chipped tooth.

  • Composite may generally be used on either front or back teeth
