Everyone would
like a perfect set of white, shiny teeth, which adds glamour and
confidence as we speak or smile. However, only a few are fortunate
enough to be blessed with such an aesthetic physical attribute.
Today, those who are not as lucky need not worry anymore. With
the level of cosmetic dentistry that we have today, it is no longer
impossible for anyone to be able to flash that perfect smile without
having to go through the long and painful orthodontic treatment
that requires braces or caps.
Porcelain dental veneers are a beautiful way to correct chipped,
crooked, or stained teeth. They are oftentimes more visible as
they are placed on the side of the tooth, touching the cheeks.
Veneers give an unsightly set of teeth an overall aesthetic
appeal by changing a tooth’s size, shape or color. Porcelain
dental veneers can actually whiten the teeth, close spaces and
fill in gaps between teeth.
Because of its bonding capability, resins are used in attaching
porcelain veneer or a thin covering of porcelain to a tooth.
The fragile and naturally brittle porcelain becomes quite strong
and durable when securely bonded to a sturdy substructure such
as the teeth.
The use of veneers by dentists can be traced way back in the
1930. The veneers were bonded with a dental adhesive tape and
were most likely to fall off. Famous movie celebrities used veneers
as “stop gap” arrangements. Dental fillings then
were made of gold, amalgam and other materials, some of which
were veneered with porcelain.
Two types of materials can be used in a veneer: composite and
porcelain. A composite venner may be built directly up in the
mouth, or may be indirectly fabricated by a dentist or dental
technician. This type of veneer is later on bonded to the tooth
with the use of a resin cement. A porcelain veneer can only be
indirectly fabricated.
Porcelain Veneer Dental Procedure
Before undergoing any medical procedure, it is best to discuss
with your dentist to assess the possibility of the veneer dental
placement not being entirely favorable or successful.
Veneer failure may happen when there is additional bonding over
old composite veneers, or when tooth surfaces have been overly
excavated and thus have insufficient tissue and high dentine
exposure, or when the procedure is done by an incompetent dental
practitioner.
Another risk factor in the porcelain veneer dental procedure
is stress brought about by fluctuation in temperature in combination
with contraction due to chemical reaction. This causes the veneer
to crack if the porcelain used is too thin and the compound utilized
for the luting process is too thick. The use of excess dye to
conceal the original discoloration of tooth to fit in with the
new overlain veneer does not have the desired result.
Ideally, for a veneer placement to be successful, there must
be an above 3 ratio of thickness of luting agent and porcelain.
There are usually four steps in the porcelain dental veneers
treatment.
On your first visit to the dentist, a thorough check is done,
after which the dentist will decide on what the best procedure
to be used in order to get maximum benefit is. Then the dentist
will make a mold or impression out of your current teeth formation.
On the next appointment, your teeth are prepared for the porcelain
dental veneers. They are buffed lightly to take away about 0.5
mm from the tooth surface. This process may need local anesthesia.
Veneer preparations can actually be done without local anesthesia.
However, it has been found that sub-gingival margin placement
inadvertently leads to dental exposure and high sensitivity to
cold-water spray and aspirator. Hence, it is more comfortable
for the patient to undergo veneer placement under a local anesthesia.
Then a mold or impression will be made to customize the porcelain
dental veneers. This will be sent to a dental laboratory and
will be used for creating a perfect fit. If you are worried on
how the veneer will look on you, you may ask your dentist to
provide you a temporary dental veneer.
When the porcelain dental veneers are ready, the dentist will
attach them carefully, adjusting the shade if necessary. Dental
cement is applied between the tooth and the porcelain dental
veneers. And lastly, a “light” touch finalizes the
procedure using a beam of light that activates the hardening
of the cement.
Indeed, porcelain veneers are a great benefit to both the dentist
and the patient. Age is not a barrier for having these veneers
fitted to improve the appeal of one’s teeth. With the help
of a reliable dental professional, best possible results of porcelain
dental procedure can be achieved.
