Composite
resins are made of a resin filled with
microscopic porcelain particles. Similar in color
and texture to natural teeth, the fillings are
less noticeable, and much more attractive, than
other types of fillings. This material is used
as a filling material for either posterior or
anterior teeth.
Posterior
teeth
A large number of people had amalgam fillings
(silver) or gold filling restorations in the past.
Some amalgam fillings contained mercury. Metal
fillings were effective, but very conspicuous
and tended to blacken in color over time. Tooth-colored
fillings or composite resin dental fillings were
created as an alternative to traditional metal
dental fillings.
 
A
tooth-colored alternative to traditional mercury
fillings (amalgam).
The
Problem:
- Decay on a portion of any tooth
- Desire to replace old-fashioned
mercury (silver) fillings
- Desire to maintain a white, beautiful
smile
The
Solution:
Tooth-colored composite resin fillings can make
old fashioned and unattractive silver fillings
a thing of the past. Composite resin is a metal-free,
tooth colored quartz-like material. The final
restoration is virtually invisible.
 
 
Advantages:
Composite fillings are more than just attractive.
They are environmentally non-toxic because they
contain no mercury. Composites strengthen the
remaining tooth and help protect it from fracture
because they bond directly to the surface of the
tooth and don't require the severe "undercut"
of a mercury filling. Research has shown that
a well-sealed composite filling can restore the
strength of a decayed tooth almost to the level
of an unfilled tooth. A well-sealed composite
filling can last as long as a silver mercury filling.
Many of our patients elect to have their mercury
silver fillings replaced before they break, or
simply to enhance the health and appearance of
their smile. The result: beautiful, strong and
healthy teeth.
 
Disadvantages:
The initial investment in a composite filling
is higher than that for a mercury filling. The
materials are more expensive and the restoration
is more difficult and time consuming to place.
However, this initial higher investment is offset
in the long run by the health benefits and reduced
likelihood of restoring potentially fractured
teeth

Alternatives:
Tooth colored inlays and onlays are sometimes
good alternatives to composite fillings, offering
excellent long term durability. In cases of extensive
decay, inlays and onlays are the only alternatives
to composite fillings.
Anterior
teeth
Broken tooth is repaired quickly, easily
and inexpensively Another method of handling esthetic
problems is cosmetic bonding. The broken tooth
was restored with a composite resin filling material,
no anesthesia was required, no tooth structure
was removed. The result is an excellent restoration
that improves the patient's appearance.
 
Composite resin can be used to
cover up areas of discolouration or surface
defect in front teeth.
 
It can also be used to close
small spaces between teeth.
 
Alternatives:
Resin Bonding can do almost anything that can
however the final appearance is not quite as good
with Resin Bonding as it is with Veneers . In
the short to medium term however resin bonding
represents a cost effective cosmetic solution.
