White fillings are now becoming a popular alternative to amalgam (silver & mercury) fillings. The development of new dental materials means that it is much easier to find a perfect match for the existing shade of your teeth. In most cases it is quite impossible to see that the teeth actually have fillings. When the size of a “filling” exceeds a certain proportion of the tooth, it must be replaced with a “cap”, also called a “crown”. Porcelain crowns look very natural and don’t have a dark metal line. Porcelain crowns reflect light with a natural healthy glow.
