Restorative Dentistry
Adhesive Dentistry
"Adhesive Dentistry" is
a relatively new term and refers to the ability of certain materials
to change the surfaces of the teeth, allowing other materials to
adhere or stick to that surface without compromising a lot of tooth
structure. When plastics (composites) were first introduced, there
was only one shade. They had to be locked in with undercuts, and
eventually turned more yellow.
Today we have solutions and techniques
that alter not only tooth structure but also other surfaces, allowing
the bonding of composites, porcelain, or metals to one another.
Multiple shades are available, and these materials do not change
color.
Amalgam Controversy
Recently, there has been much hoopla made about the efficacy of
amalgam fillings. Specifically, does the mercury cause health problems
in patients?
First, one must understand that an "amalgam"
is an alloy or combination of mercury with other metals, forming
a new composition with completely different properties from the
original metals,
Second, the health hazard really involves the dentist
and assistants who handle the mercury. By the time the amalgam is
placed in the mouth, there is very little risk to the patient. However,
some patients may exhibit an allergy to the amalgam, but this is
very rare.

Advantages of the new plastic (composite) fillings
include removal of less tooth structure, aesthetics, prevention
of tooth fracture and, in many cases, no anesthetic (shots). Unfortunately,
many dental insurance policies still consider posterior composite
fillings as only aesthetic, and thus pay very little toward their
cost. What a tragedy that we have to entrust the quality of care
to these companies.

As a filling for the posterior (rear) teeth, amalgam
was the only choice for many years. Major advancements in both the
composition and application of plastic materials have revolutionized
dentistry, making amalgam obsolete.
