When teeth have been damaged by disease (decay/cavities) or trauma, they need to be repaired. Fillings are the restoration of choice for minor to moderate repairs. Larger repairs may require crown placement. They are made of either metal (amalgam) or resin (composite).
In modern dentistry, a combination of art and science uses nature as a guide by constantly looking for materials that more closely mimic teeth in form and function.
What is the best choice?
When recommending any particular filling material for your teeth, your dentist will consider the current condition of the teeth, the size of the area to be restored, the location of the teeth involved and the bite forces (chewing, shearing, grinding, etc.) on the teeth during chewing and other normal movements of your jaw. Also under consideration will be the strength, esthetics, cost and longevity of dental filling materials because these may vary greatly in different situations and for different patients.
