A dental restoration or dental filling is a dental restorative material used to restore the function, integrity and morphology of missing tooth structure. The structure loss typically results from cavities 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 which is supported by dental implants.

Dental restorations may be fabricated out of a variety of materials and composite resigns.
