White
Fillings
In the past, teeth were most commonly repaired with amalgam (silver)
fillings or gold restorations. Thanks to advances in modern dental materials
and techniques, teeth can be restored with a more aesthetic and natural
appearance. There are different types of cosmetic fillings currently
available. The type used will depend on the location of the tooth and
the amount of tooth structure that needs to be repaired.
Direct Composite
The most simple form of 'white filling' is technically called a Composite.It
is made up of a composite quartz resin and usually contains some sort
of light sensitive agent. These light cured composites are extremely
cosmetic and most often bonded into place in one appointment. For this
reason, they are often referred to as "bonding". They can
be used in both the front of the mouth as well as in your back teeth.
These materials come in a variety of shades so that they will match
the color of your own teeth. Some of these composite materials have
been specifically designed to actually withstand the incredible forces
you can exert when chewing on your back teeth.
In order to bond
a filling material to your tooth it is first necessary to remove decay,
prepare the tooth and then to condition the enamel and dentin. Once
conditioned, a thin resin is applied which bonds to the etched surface.
The bond strength of these fillings is incredible. Today we can bond
plastics and even amalgam (silver fillings) to your teeth. Bonding increases
the strength of these restorations far beyond those of only a short
time ago.
After placement,
composites are hardened by shining an intense light on them for a specified
period of time, usually around 40 seconds. Since we tend to look at
this light all the time ( many times a day) it is necessary for us to
protect our eyes from it with an orange shield. It is not necessary
for us to protect your eyes since you look at this light only once in
a while. However, it is probably a good idea for you not to look directly
into the light anyway. An ounce of prevention, is indeed, worth a pound
of cure!
We are constantly
asked the same question, " When can I eat?". Well, after placement,
as long as you brought your own food and you share, you may chew right
away. These fillings are instantly hardened by the light. Your teeth
may experience some degree of temperature sensitivity for a few days
to a week. If it does not disappear within that period of time, contact
your dentist.
Indirect Composite/Porcelain Inlay
The other type of 'white filling' is called a Composite or Porcelain
Inlay. These fillings are usually placed in back teeth when esthetics
is of utmost concern. In order to increase their strength and longevity,
they are fabricated in the laboratory and then bonded into position
in the office. This is a two visit procedure rather than the one visit
required to place a composite filling. However, when it comes to strength
and cosmetics, the extra time and expense is well worth it! I hope that
you now understand a little bit more about white fillings.
