Composite Fillings

A composite filling is a tooth colored quartz-like material. After tooth decay is removed and cleaned, this tooth colored material is layered into the tooth. Each layer is hardened or cured with highly intense visible light, and the final surface is shaped and polished to match the tooth. The final restoration is virtually invisible.


Composite fillings are more than just attractive. They are environmentally non-toxic because they use no mercury. They are stronger than silver fillings because they bond directly to the surface of the tooth. They protect the tooth from fracturing because they don’t require the severe “undercut” (removal of healthy tooth structure) of a mercury filling.
