More
often than not, most of us get our teeth filled by dentists and few
are blessed with teeth that don't decay no matter what they do! But a
beautiful smile that projects neat teeth is everything that matters.

In the
early records of dental filling, Amalgam, one of the materials used
for tooth restoration after decay damages the tooth, is composed of
liquid mercury, silver, tin, and copper. This material had been used
for more than a hundred and fifty (150) years. It is also referred to as
“Silver Filling” because of its appearance.

Another
material used for tooth filling is Composite Resin or “White
Filling” which is a tooth-colored plastic, again used to
reconstruct decayed teeth. This was developed in 1962 by combining
epoxy resin and methacrylic acid with silanized quartz powder.

The
material for your dental composites consist of resin matrix (organic
content), fillers made of either quarts, ceramic or silica (inorganic
part), and coupling agent.
Having
a composite resin offers a couple of advantages and disadvantages, as
well. First advantage is that dentists can easily blend shades to
create a nearly identical color as that of a natural tooth. Second,
composites offer adhesive property to your tooth supporting the
remaining structure which helps prevent breakage. It also provides
insulation from excessive temperature changes.

The
disadvantage is that you may experience sensitivity after. The color
of your filling can also slightly change especially when you drink
tea, coffee or other staining foods. You can somehow talk to your
dentist which filling to use for your comfort. Composites somehow
tend to wear off sooner than Amalgams in larger cavities, though they also work well with smaller cavities.
Although,
composites have a life expectancy an average of two (2) to ten (10)
years.
