Cosmetic bonding is a procedure in which a tooth coloured material is applied layer by artistic layer to the surface of the tooth. Bonding covers discolouration, repairs chips, breaks and cracks and closes gaps between teeth. A composite resin filling may be used when only a small amount of tooth structure needs replacement. Composite bonding is one of the most conservative, versatile ways to aesthetically restore a multitude of cosmetic problems.
Contouring is the artistic adjustment of tooth structure without the need of filling material to adjust or correct the line angles of a tooth. This works well for minor chips or reshaping pointy teeth. It is also highly conservative and versatile.
