First of all, let’s go back to see the day when you were
born. As a newborn baby, there were no dangerous bacteria inside of your mouth.
As you grew older and became a child, bacteria found its way into your mouth.
It may possibly happen when your mom kissed you or when you licked the floor as
a baby. In any case, these germs have now set up permanently residence inside
of your mouth & you will have to be deal with them for the rest of your
life.
These
germs live on your teeth. Every time
when you eat something that they enjoy eating, such as ice-cream, candy, which
means you provide food for them. Feeding these little creatures does not sound
like such a bad thing. After eating, bacteria produce a very strong acid that
eats away at your teeth. If you do
not remove this sticky layer of bacteria by flossing and brushing, the bacteria
will keep destroying a little amount of your tooth structure every day until you get a hole in your tooth.
Our
bodies have the amazing capability to repair injured structures. For example,
when we fracture a bone, our body is capable to heal the bone by creating new
cells that join the bone back together. Unfortunately, this is not true when it
comes to our teeth. Although we get
two sets of teeth in our life, once
a whole forms in a tooth, the body
cannot repair it. Long time ago, cavities ultimately caused people so much pain
that they would have the tooth removed.
But now, modern dentist has found a way to let you keep your decayed teeth. All things needs to be done are
to have the bacteria efficiently removed and then to replace the hole in the tooth with a hard, tooth-like material which is known as a dental filling.
There are a variety of different materials which can be used
for filling teeth. This article, I will only discuss the two most
common filling materials, which are amalgam
& composite resin.
Amalgam Fillings
Amalgam
fillings are more usually known as
silver or mercury fillings. They are
made up of zinc, silver, copper, tin, and mercury. Amalgam fillings have been used for over 180 years in the field of
dentistry. When the metals are amalgam come together, they are form a soft
material which can be used to build your tooth
back to its original form. After a few minutes, the amalgam is going to be
hardened as the metals integrate together. While pure mercury is toxic, the
mercury originates in amalgam a filling is locked inside when the filling
hardens and is therefore not harmful.
Composite Fillings
Composite resin fillings are more usually known as white fillings, tooth-colored fillings, & direct veneers. They
are made up of very small pieces of silica bounded by plastic resin .Composite fillings are latest one than amalgam fillings and are continuously
improving. The composite resin is concerning the consistency of modeling clay.
In organize for the composite to harden; the dentist shines a bright blue light
on it. Through a composite Fillings series of chemical reactions, this resin hardens into a very
strong material which looks very much like a natural tooth.
