Porcelain crowns can look life-like eliminating those black lines visible at the edge of the older porcelain and metal crowns. They are strong, long-lasting and absolutely stunning in their recreation of natural teeth. And the color is so natural, you'll have a very difficult time telling these from your original teeth...and thanks to the latest technology, our high-speed x-rays can show, in detail, what's happening underneath these new materials - unlike gold crowns which hid the signs of disease and decay.
