1. Inlays and Onlays
These are also known as indirect fillings, which are made by a dental laboratory, and they are used when a tooth has mild to moderate decay or there is not enough tooth structure to support a filling. Provided there is no damage to the tooth cusps, the inlay is placed directly onto the tooth surface. When the cusp or a greater portion of the tooth is damaged, however, an onlay is used instead to cover the tooth’s entire surface.
Inlays and onlays are made in a dental laboratory from a composite resin material and attached to the teeth with adhesive dental cement. They provide support to strengthen teeth, restore their shape and avoid any further decay or deterioration.
