White
fillings have always been considered less
long lasting than silver amalgam fillings.
But there are now new materials available
with properties comparable to silver
amalgam, and these are proving to be very
successful. The life expectancy of a white
filling can depend greatly on where it
is in your mouth and how heavily your
teeth come together when you bite. Your
dentist can advise you on the life expectancy
of your fillings. However, any fillings
provided on the NHS are automatically
guaranteed for one year.
It is usually best to change fillings
only when your dentist decides that an
old filling needs replacing. If so you
can ask to have it replaced in a tooth-coloured
material.
Some dentists prefer not to put white fillings in back teeth as they are not
always successful. One way around this would be to use crowns or inlays, but
this can mean removing more of the tooth and can be more expensive.
