Dental bonding is a simple cosmetic procedure which involves the application of a tooth-colored composite resin on a patient’s teeth to help restore or improve the aesthetics of their smile. Post its application, the composite resin is exposed to a special light to help it harden and bond to the teeth.
When is dental bonding required?
Here are some instances where dental bonding can prove effective:
- Treatment of discolored teeth to enhance their appearance
- In repairing chipped or cracked teeth
- As fillings for cavities in order to help in the treatment of decayed teeth
- Reshaping teeth to improve the aesthetics of a smile
- For filling in spaces between teeth
- Bonding is often used to make teeth appear longer
- Composite resins can be used as an alternative over amalgam fillings when cosmetics are of primal importance
- In protection of the root of a tooth after receding gums expose them to risks of infection and decay
Generally, the dental bonding procedure is divided into two distinct steps which are as follows:
Generally, dental bonding does not require any intensive preparation. However, the step gains importance if dental bonding is being used for filling the cavity of a decayed tooth. In such cases, dentists drill the damaged tooth to change its shape and may use local anesthesia to numb the area. Dentists use a shade guide to select a composite resin that closely matches the color of the patient’s teeth.
Following the preparation and selection of the composite resin color, the surface of the tooth on which the resin has to be applied is roughened up. A conditioning liquid is then applied to the teeth. These steps ensure the bonding material adheres to the tooth surface. Post these steps, the dentists apply the chosen tooth-colored resin onto the tooth, molds and smoothens it out to the desired shape.Next, the resin is exposed to a bright blue or laser light to harden the material. The dentist then once again shapes and trims the resin in addition to polishing it to match the appearance of the tooth surface with the other teeth.
Dental bonding of one single tooth requires about 30 to 60 minutes for completion.
