Silver amalgam has served as a filling material for teeth
since the 1840s, but technology has advanced to where we can place white
fillings on back teeth. White fillings can be made out of composite resin or
porcelain, depending on the size and location of the filling in the mouth.
Advantages of White Fillings
-
They require less removal
of tooth structure. In order to be strong enough, silver amalgam fillings have
to be at least two millimeters deep, and all weakened tooth structure needs to
be removed. Because white fillings are bonded to the teeth, the weak and
undermined tooth structure can be left alone, and there is no minimum depth
required.
-
They are more comfortable.
They don't conduct heat and cold the way metal fillings do, and in the bonding
process, the sensitive part of the tooth is sealed, so there is less
sensitivity.
- They don't detract from your smile. When you are laughing or having
fun, people can usually see you back teeth. It is much more attractive for
people to see white on your back teeth instead of black.
