Aesthetic fillings consist of a specialized composite of high-strength resin impregnated with various types of ceramic filler particle. They are manufactured in various colors, which can be mixed so that the filling blends seamlessly with the color of your natural tooth. They have been used routinely in the front of the mouth but recent improvements in their strength have meant that they now offer a predictable and aesthetic alternative to the silver ‘amalgam’ fillings.
Composite fillings are more difficult to place than silver fillings and therefore they can take longer to complete. The main disadvantage is their life expectancy. Aesthetic fillings have always been considered less long lasting than silver amalgam fillings but the newer materials are proving to be very successful. We only use superlative materials which have been subjected to stringent tests and research.
The life expectancy of your composite filling, as well as any filling in general, can depend on the depth of cavity and its position in the mouth; your dentist is best positioned to advise you.
