Bonding or resin material
is composite material that is formed into a thin covering
and used to conceal the tooth and improve its appearance.
It can be used to fix chips or cracks, change the shape
or color of a tooth or even make crooked teeth look
straighter. Unlike porcelian veneers which require that
impressions be made and the covering be fabricated in
a lab, tooth bonding can be performed by your cosmetic
dentist in one office visit.
the procedure:
The first step in bonding is to make sure that you properly
match the material with the color of the existing tooth.
Then, a drill is used to roughen the enamel surface
of the tooth, so that there is a smooth transition from
the existing tooth to the bonding material.
Often times you don't even need
anesthesia. A conditioning gel is placed on the tooth
to "open" the enamel, ensuring a better bond
to the tooth. Then a resin adhesive is placed on the
tooth, like a very thin film of glue, to help the bonding
material adhere to the tooth.
The bonding material is then applied
to the tooth and shaped and sculpted to the desired
form. A high intensity curing light or laser is used
to harden the material, and then it is polished to a
high finish.
cost: Composite tooth
bonding averages $200 to $500 per tooth.
results: Very large
bonding restorations can break and stain if the individual
is not careful with them, but in most cases, tooth bonding
will last from 3 to 7 years.
