Metal crowns are usually made from gold alloys and are used for the restoration of back teeth. They offer superb strength and their wear rate is close to that of natural teeth. Metal crowns are the most resistant to wear and breakage and do not harm the natural tooth or the gum tissue. They are a suitable option when aesthetics are not of paramount importance. Their only disadvantage is their colour, but other than that, they are long-lasting, healthy, easy to work with and extremely durable.
