Nowadays fillings are not only functional, but can be natural looking as well. Many people don’t want silver fillings that show when they laugh or smile because they are conscious about the way they look.
White fillings are an aesthetic alternative to silver amalgam fillings. They bond to the tooth which means the dentist has to remove less of the tooth when preparing the cavity.
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 the mouth and how heavily your teeth come together when you bite.
