Direct Tooth Bonding
Bonding is a popular treatment option because it provides a successful attachment between the filling material and the tooth’s original enamel and dentin. It looks like the original tooth and functions like it as well.
Direct composite bonding is used to recreate a smile in an additive manner, where little or no tooth reduction is needed. Direct bonding, in the hands of a skilled operator, is less costly than porcelain veneers and crowns and can be long-lasting with proper maintenance.
Enamel and Dentin
Teeth are a perfect combination of both strength and resilience and this is created through the fusion of enamel and dentin.
Enamel is the outer shell of the tooth or the portion that is visible within the mouth.
Dentin is the inner core of the tooth. Composite resins have properties similar to dentin and are a combination of a plastic resin and silica filler. This combination of materials allows for excellent tooth color replication and reliable adhesion.
Bonding to Repair Broken or Chipped Teeth
Tooth bonding is used in several different ways but is probably most useful for repairing chipped teeth. Bonding materials (high-density, modern plastics called composite resin) and porcelain are more natural in color and can be designed to perfectly match the surrounding teeth making it difficult to discern there ever was a broken tooth.
Transitional bonding is used for anything from a mock-up to a full-mouth rehabilitation. It’s called transitional because it allows the patient to transition into more permanent dentistry as he or she can afford, or as the treatment sequence demands, and it allows the dentist time to work out any bite-related and esthetic issues. Transitional bonding is an important tool in the skillset of an accomplished cosmetic dentist.
