Dental fillings is a restorative material used to restore the function, integrity and morphology of missing tooth structure.
The structural loss typically results from caries or external trauma.
It is also lost intentionally during tooth preparation to improve the aesthetics or the physical integrity of the intended restorative material. Dental restoration also refers to the replacement of missing tooth structure that is supported by dental implants.
Fillings are also used to repair cracked or broken teeth and teeth that have been worn down from misuse (such as from nail-biting or tooth grinding).
What Types of Filling Materials Are Available?
Today, several dental filling materials are available.
Teeth can be filled with gold; porcelain; silver amalgam (which consists of mercury mixed with silver, tin, zinc, and copper); or tooth-colored, plastic, and glass materials called composite resin fillings.
The location and extent of the decay, cost of filling material, patients' insurance coverage, and your dentist's recommendation assist in determining the type of filling best for you.
