Dental bonding is a technique in dentistry that is used to attach tooth-colored filling materials to the enamel of teeth. This method allows us to restore teeth by removing a minimum of tooth structure. Dental Bonding also strengthens teeth.
How does dental bonding work? A special solution called an etchant is placed on the tooth and this solution makes microscopic openings in the enamel. When the tooth-colored material is placed on the tooth, the filling material fills the openings in the enamel. The filling material is sculpted to replace the missing tooth structure or change the shape &/or color of the tooth. Once the desired appearance is achieved, a special dental light called a curing light is aimed at the filling and the light sets the material and makes it hard. The filling literally locks into the openings made in the enamel by the etchant. This process strengthens the tooth and because the filling material locks into or bonds onto the enamel, little or no tooth structure has to be removed to secure the filling.
Tooth-colored fillings can be bonded into back teeth in some instances to replace unsightly old silver fillings. These types of fillings are better in premolars than molars. Molars have to withstand the most pressure, so it’s better to use stronger materials like porcelain inlays/onlays or crowns on molars. Molar teeth can be restored by using dental bonding to bond the inlay or onlay to the tooth.
