are the newest type
of filling in common usage. They are commonly known as white
fillings. They are a porcelain/plastic hybrid that is bonded
directly to the cavity preparation. Composite fillings were
created as an alternative to traditional metal dental
fillings. They are colored to look like natural teeth and
are more esthetically pleasing than amalgam or gold
fillings. They are also strong, durable, and make for a very
natural looking smile.
From a cost standpoint, this tooth colored restoration is closest to silver amalgam,
but composite resin restorations must be places nearly perfectly to provide adequate service.
They can compete with silver amalgam in small to moderate size tooth defects.
Many new materials now make these restorations much better than in the past.
These are the most common restorations for front teeth.
will give you a local anesthetic to numb the area before
preparing an access to the decayed area of the tooth and
removing the decayed portions. Traditional drills, micro air
abrasion or even with a dental laser can be used to
dental material is then used to open up the pores of your
tooth's dentin and roughens up the surface of the exposed
enamel. This creates a stronger bond between the tooth and
the filling. The bond resin is applied to stick the
composite to your tooth. This material is made of the same
dental resin as the composite however it is much more fluid.
composite filling, your dentist will be able to preserve
more of the natural tooth as the composite resin can be
bonded to the tooth in thin layers and slowly built up to
form a complete filling. A bright dental light will harden
each layer before the next is applied.
decayed area of your tooth is close to a nerve, a special
liner can be used to protect the nerve. A special dental
material is then used to open up the pores of your tooth's
dentin and roughens up the surface of the exposed enamel.
This creates a stronger bond between the tooth and the
filling. The bond resin is applied to stick the composite to
your tooth. This material is made of the same dental resin
as the composite however it is much more fluid. This layer
is then hardened by the bright light in the same way as the
filling is completed, your dentist will use a special
articulating paper, to adjust the height of your dental
filling and to ensure that your bite remains correct. Your
tooth is then polished.
If such a
filling is not going to be enough to protect your damaged
tooth, or if your tooth enamel is thin and will easily
fracture, or if your tooth has had a root canal that
weakened your tooth condition, your tooth may require
additional protection such as a crown.
It is important to discuss this procedure with
as there are several personal and medical factors to take into consideration. You may also have the option of

ADVANTAGES & DISADVANTAGE OF COMPOSITE FILLING
- Composite Filling is much cheaper than crowns or veneers and research indicates
that it is completely effective in more than 90% of people.
- The composite bonds to further support the remaining tooth
structure helping to prevent breakage and damage to your
- They look more natural as they are color blended to match
your natural tooth color. These fillings are often used
to improve the appearance of misshapen, chipped or
- Composite fillings last from six to twelve years or more.
- The procedure usually takes just one visit to your dentist.
- There is very little sensitivity to hot or cold items, often
experienced with amalgam fillings.
- The dentist won't need to drill as much of the tooth
structure as the composite is applied in layers.
- These restorations are tooth-colored and nonmetallic.
When places over etched enamel, they will bond the
remaining tooth structure back together.
- Composite resin fillings require more time to apply than amalgam fillings.
- As a result of the time required there is an increased cost for
placing composite fillings.
- These restorations must be placed perfectly for optimal service.
All materials in this category wear more under biting loads than do
metal restorations. However, when appearance is a primary factor,
they should be used.
A small percentage of teeth into which this material has been placed is sensitive to temperature or pressure after the placement.
This sensitivity usually goes away, but a few teeth require endodontic (root canal) therapy because of continued sensitivity.
Composite resin wears faster than metals; this characteristic can cause the need for replacement sooner than metals.
Where appearance is not a factor, silver amalgam is the most used alternative, but gold inlays and onlays,
tooth-colored inlays and onlays, and crowns (caps) may also be considered. Composite filling can be used
for cosmetic improvement on front teeth such as
composite facing or
These restorations may cost up to two or three times more than the cost of silver amalgam restorations in back teeth.
The higher cost is related to the extra skill required to place these restorations.
RESULT OF NONTREATMENT
Untreated decay will eventually destroy much of the tooth, kill the dental pulp (nerve),
and may require significant expensive therapy to overcome the problem.
