Dental bonding (composite resin) cant be utilized as a way to improve the appearance of a defect found on the surface of a tooth, to replace tooth structure that has chipped or broken off, or to repair damage caused by tooth decay. This technique can also be used to resurface the entire front side of a tooth, just to improve its cosmetic appearance. You can do bonded fillings on both front and back teeth. This procedure is usually done in one appointment and is very affordable.
