Many people have fillings of one sort or another in their mouths. Nowadays fillings are not only functional, but can be natural looking as well.
A filling is a way to restore a tooth damaged by decay back to its normal function and shape. When a dentist gives you a filling, he or she first removes the decayed tooth material, cleans the affected area, and then fills the cleaned out cavity with a filling material.
Often people don't want silver fillings that show when they laugh or smile because they are more conscious about the way they look.
White fillings had been considered less long lasting than silver amalgam fillings but there are now new materials available with properties comparable to silver amalgam.
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.
