Old and Unsightly Fillings
Newer kinds of fillings made from composite resins and porcelain can restore unsightly fillings; many people are surprised how natural these kinds of filling materials can make a tooth once covered by the old-fashioned silver amalgams (mercury).
Porcelain fillings, often called inlays or onlays, are a better option when repairing a restoration (filling). Porcelain lasts longer and is more aesthetically pleasing than the older type amalgam fillings. If a patient has a allergy to mercury these porcelain fillings are indeed the treatment of choice.
