| If you want your fillings to be invisible, composite resins can restore a decayed tooth or repair a defect. Mostly, composite resins are used on front teeth that bear less chewing pressure, although composites have been developed that can be used for selected fillings in back teeth such as molars. Composites are composed mainly of two primary ingredients: a binder of plastic resin and a filler of finely ground, glass-like particles that give them a lifelike appearance and durability. Composite fillings can be placed in one visit, just like a traditional amalgam filling. |
