Inlays and Onlays
Unlike large, ugly metal fillings of years
past, Dr. Vaughan prefers a more attractive restoration that actually
strengthens the tooth. Inlays and onlays are the perfect solution to creating
healthy, beautiful restorations for your teeth.
What Was Wrong With My Old
Fillings?
In recent years, dentists have learned
that the metal fillings in your mouth act much like metal does outside the
mouth. Exposed to heat and cold, such as hot coffee or ice cream, the metal
fillings in your teeth expand and contract. As they shift, they can actually
weaken the teeth they were meant to protect. Often, the expansion and
contraction leads to the entire tooth cracking.
As the filling expands and contracts, it
can also leave a small opening where harmful bacteria can enter and become
trapped, leading to further decay of the tooth. Rarely does Dr. Vaughan remove
silver fillings without finding additional decay underneath.
Why Would I Want An Inlay
Or Onlay Instead Of A Metal Filling?
An inlay or an onlay is a much more
conservative restoration for the tooth than a metal filling. While traditional
fillings can reduce tooth strength up to 50%, inlays and onlays made of high-strength, porcelain can actually increase tooth strength by up to 75%, lasting
from 10 to 30 years.
What Is An Inlay?
Inlays, similar to fillings, are used
inside the cusp tips of a tooth. Inlays are created out of fired porcelain,
allowing Dr. Vaughan to perfectly match the color of your natural tooth, making
the restoration invisible to the naked eye.
Much like a crown, Dr. Vaughan will create
a temporary inlay for your tooth, take an impression, and send the model to the
lab for the porcelain restoration. You will need to see the Doctor to have the
final inlay bonded to the tooth and polished.
What Is An Onlay?
Onlays are made of fired porcelain, just
like inlays. However, onlays are more substantial reconstruction, extending out
over one or more of the cusps of the tooth. Where a crown may have been
necessary, an onlay can often be used to repair the damaged portion of the
tooth, leaving much more of the original tooth structure intact.
Onlays are also made in the lab, and will
require a return visit. Your temporary will hold up to normal wear until your
return appointment.
