Composite fillings are a natural looking, tooth colored alternative to conventional silver colored fillings. Composite fillings are a mixture of resin and fine particles that emulate natural tooth color. They provide an aesthetic restoration and can be bonded to the teeth for increased adhesion. Silver amalgam fillings however, possess great strength and durability, and are less sensitive to isolation during treatment.
Ionomers are a tooth colored filling material that is fabricated from numerous types of material including ground glass and acrylic resins. Ionomers are used for fillings near the gum line or tooth root to reduce influence from bite pressure. They also produce small amounts of fluoride to clean and strengthen the enamel in the affected area.
Porcelain fillings are produced from a combination of ceramic and glass powder materials. They are used for restorations such as crowns, veneers, onlays, and inlays. They are more durable than ionomers but can be damaged from extensive teeth grinding or bite activity.
