White fillings can be used to replace mercury
or gold restorations, or even new cavities. They provide a more natural
tooth-like appearance, and by nature of their chemistry they allow
a more conservative approach to the restoration of teeth.
Large long term mercury fillings are likely to
cause the surrounding tooth structure to fracture. Mercury fillings
are packed under pressure and as a direct result they put undue stresses
on the natural tooth structure, which will in time, give way.
White fillings are used to restore diseased teeth and there is no
need to extend or drill into healthy tooth structure as would be the
case with the old style treatments. After the safe removal of the
decay using a special dye and laser to indicate the extent of the
lesion, a whole filling can be bonded to the affected area.
Depending on the size and extent of the decay present, there are two
treatment options. The first being a composite resin filling procedure.
This is a direct procedure that can be completed on the day of your
visit. For larger broken down teeth an indirect restoration may be
required. These are known as inlays or onlays depending on the size.
These are custom made in a laboratory using high grade porcelains
for strength and durability. |
