Bonding
Bonding can fix crooked, gapped or badly stained teeth.
Tooth bonding is a cosmetic dental procedure that bonds tooth-colored
material (resin) to the surface of a tooth. Bonding is likely the
easiest and least expensive of cosmetic dental procedures.
The
resin used in bonding can be shaped and polished to match the surrounding
teeth. Bonding can also be used to create temporary veneers to see
if you like the new look before you decide to undertake a more involved
procedure, such as porcelain veneers.
Bonding is used to:
- Reshape teeth
- Fix crooked teeth
- Close unwanted gaps
- Cover (and whiten) badly stained teeth
Unlike veneers, bonding can be done in a single visit. The
procedure is called bonding because the material bonds to the tooth.
No preparation is needed for bonding and anesthesia is usually not
necessary. The resin used in bonding can be shaped and polished
to match the surrounding teeth. Sometimes, bonding can also be used
as a cosmetic alternative to amalgam fillings or to protect part
of a tooth's root that has been exposed due to gums receding.
To do a bonding procedure, the doctor will use a shade guide to
select the composite resin color that will match the color of the
tooth. Once he has chosen the color, he will slightly etch the surface
of the tooth to roughen it. The tooth will be coated lightly with
a conditioning liquid, which helps the bonding material adhere.
When the tooth is prepared, the doctor will apply the resin and
then mold and smooth it until it's the correct shape.
The resin is then hardened with an ultraviolet light or laser. After
the bonding material hardens, the doctor will further shape it.
He will then polish the resin until it matches the look of the rest
of the tooth's surface. It usually takes less than an hour to complete
the bonding procedure for one tooth.
The bonding resin is not as strong and durable as a natural tooth
and can sometimes be chipped. Bonding can last several years
before it needs repair.
