Cosmetic bonding is made of the same material as a composite filling. It is used on the front surface of a tooth to improve the appearance of the tooth. Dr. Peter McDonald treats his patients with cosmetic bonding when they are unsatisfied with one or more of their teeth and cosmetic resin can be applied to improve their smile. Cosmetic bonding can be used to fix discolored, broken, or even crooked teeth. This treatment improves the aesthetics of these damaged teeth, by placing white composite resin over the facial aspect of the tooth to maintain a beautiful white smile.
