A filling is a procedure in which a dentist removes tooth decay and replaces it with a restorative material. This restores the function and health of your tooth, helping it avoid further decay or damage. Cosmetic fillings are made to match the natural shade of your teeth and are considered a tooth-colored alternative to amalgam fillings. They are used to treat minor tooth decay and small cavities. In some cases, they can also be used to repair chips in teeth caused by accidents or wear. Cosmetic fillings are less noticeable than amalgam fillings and improve the appearance of your smile.
