Cosmetic Fillings
Many patients are asking our dentists about white fillings because they want their teeth to have a more pleasing, natural looking smile. White fillings, which are made from tooth colored materials, blend well with the natural color of your teeth. They don't look like metallic fillings. Composite Fillings One type of material used for white fillings is a composite resin. Composite resins are mixtures of plastic and glass, which are blended to match the natural color of your teeth. Composites can be used to restore decayed areas, to replace previous restorations, and also for cosmetic improvements of the smile (see bonding page). Since they blend well to natural tooth enamel, our dentists may recommend composites if the teeth needing restorations are near the front of the mouth. Composite fillings can usually be placed in one office visit. The tooth is first prepared by removing the decay. The dentist may place a band around the tooth and the area is isolated from saliva during the restoration. An adhesive is placed in the tooth followed by thin layers of composite resin, using a special light to harden each layer. The final layer is shaped to the natural contours of the tooth, and then polished. The main advantage to composite fillings is the similar appearance to natural teeth. Another advantage is that they require the removal of less of the healthy part of the tooth to hold the filling in place. The composite material bonds to the tooth to support the remaining tooth structure. One disadvantage to composite fillings is that they tend to wear faster than silver fillings when placed on the chewing surfaces or in larger cavities, although in smaller cavities they hold up as well as silver fillings. The composite filling can stain or discolor slightly over time. If you prefer, our dentists can place a clear plastic coating over the composite material, to protect the color. The fee for composite fillings is higher than the fee for a silver filling.
