Dental bonding is the process of adding tooth colored filling material (composite) to existing tooth structure. Dental composites come in many different tooth shades so matching your tooth color has become less challenging as of late. Little or no preparation of the tooth is needed to add composite to the tooth.
The tooth is roughened and conditioned with a gel. An adhesive is place and then the composite. The material is then cured with an ultraviolet LED light. The bonding can then be refined and polished.
Indications for bonding:
Small chips in teeth
Congenitally misshaped teeth
Cover exposed tooth as a result of gum recession
Lengthen short teeth
Repair worn edges of teeth
Bonding is an excellent, cost effective, minimally invasive treatment option. Bonding does have some disadvantages. Composite tends to stain over time. The interface of the composite and tooth will eventually breakdown and fail. Also the bonding can chip or completely break off the tooth. However, this treatment option is an excellent alternative for some cases.
