| There are many
cosmetic dental techniques that can improve your smile. |
Bleaching:
For whitening of dark, dull, or stained teeth, bleaching
may be the simplest solution. Bleaching is performed by
taking an impression of your teeth and making a duplicate
model of them. On this model, a soft, thin, clear tray is
fabricated. This tray is filled with a bleaching gel and
placed directly over the teeth in the mouth. This bleach
filled tray can be worn for several hours during the day
or worn at night while you sleep. Results can be seen
daily. To attain maximum results, most patients must wear
the bleaching tray for 1-2 weeks. However, the timing of
these results can be influenced by the different strengths
of the bleaching gels which are available. |
Bonding:
When teeth are chipped or slightly decayed, bonded
composite resins may be the material of choice. Bonding
is applied to a tooth via a light gun. First, the tooth
structure is cleaned and etched. Then a clear adhesive is
applied to the area needing bonding. Once applied, a
tooth colored bonding material is placed on the tooth. It
is permanently hardened and fused to the tooth with a hand
held white light gun. This process is called photo
curing. Bonding makes a great tooth colored filling for
small cavities and broken or chipped surfaces. It can
also be used to close spaces between teeth. Additionally,
it is used to cover the entire outside surface of a tooth
to change its color and shape. For the latter two
applications, bonding has its limits. It may not be
strong enough, aesthetic enough, or durable enough for
certain individual situations. When these problems occur,
the next choice would be porcelain laminate veneers. |
Porcelain Laminate
Veneers:
Many times, the demands of cosmetic changes in the mouth
are too great for simple bonding. This is when porcelain
laminate veneers may be used. Porcelain veneers
(sometimes referred to as laminates) can change an entire
smile. Porcelain laminate veneers are quick, painless,
and dramatic. They can change shape, color, size, and
arrangement of teeth or any combination of these factors.
They can be used as an alternative for orthodontic
treatment. The best part about porcelain laminate veneers
is that they can be placed in two visits. The technique
consists of first shaving a thin layer of outer tooth
structure (about the thickness of an eggshell). An
impression is then taken of the prepared teeth and is sent
to a dental laboratory. In the lab, a ceramist will make
very thin porcelain facings consisting of all the changes
in shape, size, color and teeth arrangement that are
needed to have a great looking smile. At the second
visit, the laminates are bonded onto the prepared teeth
with a white light gun. The bonding material acts as an
adhesive for the laminates. Porcelain laminates are the
most popular technique used for dramatic smile makeovers. |
Porcelain Jackets:
When there is not enough tooth structure left, or the
chewing demands in the mouth are too great for laminates,
a stronger, more extensive restoration is needed. Here we
need porcelain jacket crowns. Porcelain jackets are pure
porcelain crowns placed on a fully prepared tooth. They
are the most life-like of all full crown type
restorations. The technique initially consists of
preparing the teeth. Next, an impression is taken and then
sent to the dental lab where the porcelain jacket is
fabricated. Finally, they are placed in the patient's
mouth and permanently cemented onto the teeth. |
Porcelain Fused to
Metal Crowns:
When biting pressure is too great for porcelain jackets or
gaps from missing teeth must be filled in, metal alloy
must be placed under the porcelain for strength. This is
the porcelain fused to metal crown technique. More tooth
structure is removed to accommodate both metal and
porcelain. Once an impression is taken, a metal coping is
made on the prepared tooth. This is then covered with
porcelain. Porcelain fused to metal crowns do not have
the translucency of pure porcelain crowns. Therefore,
aesthetics may be slightly compromised in some
situations. However, a talented ceramist with experience
in custom staining can usually overcome these limitations,
thereby creating life like restorations. When teeth are
loose due to periodontal bone loss, this technique is
used. Here the crowns are splinted together by joining
the metal substructure of the crowns so they are tied
together like a small fence in the mouth. |
Porcelain fused to
Gold Inlays:
When individual back teeth are broken down but some good
healthy tooth structure remains, porcelain fused to gold
inlays are used. These are the strongest and longest
lasting of all the aesthetic back teeth restorations.
Once the tooth is properly prepared, the technique is
similar to the porcelain fused to metal crown technique.
The benefit of this restoration is the advantage of gold
underneath which supports the tooth during heavy biting
loads, thereby protecting the tooth and the nerve within. |
