Composite resin is material that is matched to the color of your teeth and hardened with the use of an ultraviolet lamp. Because the resins are matched to your tooth’s color, they become invisible when applied. We have found composite fillings also provide an excellent seal on the affected area, preventing further tooth decay. The factors that go into our decision to use composite fillings include the size of the area that needs to be filled, the location of the affected area in the mouth (i.e., a tooth that is heavily relied on for chewing), allergies the patient might have, the preference of the patient regarding the use of metals in the mouth, and whether it is necessary cosmetically to have a tooth-colored filling.
White fillings are made of a resin composite material that contains no metal at all, and more importantly, has no mercury content. It is an inertmaterial that is completely safe for the human body. After the tooth is prepped, and any decay completely removed, the resin polymer is mixed, and the color matched to your existing teeth. After placing the material into the cavity, an ultra violet lamp is used to cure and harden the resin. Then the dentist will grind down any excess, and adjust the material so that there is good occlusion for the bite of the tooth. Finally, it is polished to smooth any rough spots. When the dentist is finished, you cannot tell that there is any filling, as it will match the color of the tooth.
