Porcelain Crowns – Known for their natural teeth like color, Porcelain crowns are usually used for covering front teeth. The use of Porcelain, not being a strong material, is restricted to the front teeth only.
Porcelain bonded to metal – These Crowns have the benefit of Porcelain crowns and the strength of metal.
Ceramic Crowns – These crowns are mostly famous for their looks, hardness and the ability to be positioned at anyplace in the mouth. Ceramic crowns have teeth like color and structure which makes it very suitable to be used as dental crowns.
Gold Alloy – Used for centuries, a gold alloy crown is also one of the most famous crowns used in today’s world. Gold alloy, because of its stable and non reactive nature, is suitable for crowns as it would not produce any harmful toxins after reacting with saliva or other food items. Its hardness and stature made it an optimum choice to be used in crowns in early times.
Usually crowns are very difficult to spot and would require a careful eye. A new crown may feel little uncomfortable but one can get used to it in no time. The expected life of a crown is seven to ten years but with careful and good maintenance and oral hygiene, they can last even longer. Crowns are used only to have an improved appearance of the teeth. Although, crowns are very hard and extremely durable, they will not work for the prevention of tooth decay.
