White Fillings
Nowadays, most people want white fillings, particularly in positions where
they can be seen. Silver (amalgam) fillings are still an excellent choice,
as they are good at preventing further decay, and are very hard wearing.
They do contain mercury, which, though research has shown to be safe to
use, still causes concern for some patients. In these cases, white (composite)
fillings can be used. The benefits of white fillings are obviously colour
and the fact that they are glued to the tooth, increasing its strength.
They generally take a little longer time to do as they are more technique
sensitive to carry out. A well-polished white filling can look virtually
indistinguishable from a similar healthy tooth.
