Many patients are asking about white fillings because they want their teeth to have a more pleasing, natural looking smile.
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.
The main advantage to composite fillings is the similar appearance to natural teeth and also 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 but our dentists can place a clear plastic coating over the composite material to protect the color.
