When 50 percent or
less of a tooth has been lost to damage or tooth decay, it can be rebuilt with a
core buildup. A core buildup offers
several advantages to the patient in need of cosmetic dental repair.
First, it betters supports remaining tooth
It helps the tooth better support and retain a
It protects the sensitive dentin and pulp from
the interior surface of the dental crown.
Core buildups have
saved millions of teeth that in previous decades would have been labeled
hopeless and extracted. They not
only restore tooth functionality, but they make restored tooth look virtually
identical to surrounding natural teeth.
The majority of
dentists these days prefer to use cosmetic dental boding resin in core buildup
procedures. Cosmetic bonding resin
is biofriendly, easy to apply, and has the remarkable ability to match the color
of existing teeth.
There are several
steps involved in this procedure.
The first two steps involve putting the patient at ease and ensuring
patient safety. The gums around the
tooth are numbed, and the throat is protected by a device called a rubber
dam. This device prevents any
dental debris that results from tooth cleaning from falling into the throat and
precautionary measures are taken, the dentist then conducts a thorough
examination of the tooth. The
dentist determines how much of the tooth has been damaged, decayed, or lost, and
how much of the remaining tooth surface can be salvaged. A dental handpiece is used to remove
plaque and tooth decay and to partially reshape the tooth in anticipation of the
core buildup bonding agent.
To better prepare
the tooth surface for a core buildup, the dentist also applies mild etching
solution that creates tiny lines in the tooth enamel. When the cosmetic dental resin comes
into contact with these lines, it adheres very quickly to them and bonds to the
Some kinds of
cosmetic dental resin harden almost instantaneously. Others require the application of a
special light to harden. Once the material hardens, the dentist again refinishes
the surface of the tooth and takes impressions of the patients teeth. A model is made of the patients
mouth. This model is sent to a
dental laboratory so that a crown can be fashioned for the new core
In the meantime, the
dentist completes the first appointment by placing a temporary crown over the
tooth. This protects the core
buildup while the patient waits for the lab to finish making his or her
crown. It normally takes 10 days to
3 weeks for the lab to finish.
When the crown is
ready, the patient will be called back to the dental office to have it fitted to
the tooth. The dentist will first
fit it without cementing it and check to make sure it is even with the alignment
and the bite of natural teeth. If
no changes need to be made the dentist will go ahead and use cosmetic resin or
dental cement to permanently bond the crown to the tooth.
Dentistry is a specialized field that requires extensive knowledge and
experience to be done correctly. The Medical Center Dental Group in
Houston, Texas brings all of that and more to the direct benefit of each and
every patient we treat. Although we are located in the world famous Houston
Medical Center at Scurlock Towers, we routinely see dental patients who travel
from Austin, San Antonio, Dallas, Beaumont Midland and Houston, Texas to
see Dr. Dale Brant, Dr. Charles Campbell or Dr. Elizabeth
OSullivan-Winslow for their cosmetic dentistry
