Dental bonding mainly treats teeth in the front of the mouth. It is performed on teeth that are broken, chipped, show signs of decay, have contour irregularities or have gaps to fill-in between other teeth. A restoration made in a laboratory is called an indirect filling. Removing a cavity and immediately replacing it with a tooth-colored composite is a direct filling. A conditioning liquid helps bonding material adhere to the tooth. Tooth-colored resin is applied and shaped to the tooth. A curing light bonds the material to the tooth and the dentist trims and reshapes the tooth. The bite alignment is checked and the tooth is polished to match the natural teeth.
