Have you ever noticed the dark black or gray line at the gums, when someone smiles? Usually these are old crowns which have metal underneath, giving the appearance of dark gums. With today's stronger and more aesthetic materials, we are able to offer you crowns which are metal free and made of only porcelain to give your teeth a more natural appearance. Furthermore, old, unsightly black mercury amalgam fillings can now be replaced with aesthetic materials such as resin and porcelain fillings, crowns or onlays. These materials are bio-compatible and look and feel like your natural teeth. They are strong and long lasting.
