Types of Dental Crowns

Cosmetic dentistry procedures are beneficial for different types of dental imperfections. One of the procedures include placing a dental crown which is a prosthetic cap-like object cemented onto a damaged tooth. This enhances the appearance of a badly broken tooth, strengthens it, and fixes the alignment of the mouth. It is like a cap that blankets over the top portion of the tooth and is fit by reducing the size of the tooth. It is prepared by first taking an impression of the tooth over which the cap has to be placed. This customizable feature is instrumental in strengthening broken down or weak teeth. You may need to visit your dentist to get a dental crown for these reasons:

  • To cover a dental implant.
  • To fix a worn-out tooth or a broken tooth.
  • To help hold a dental bridge in place.
  • To mask a misshapen or severely discoloured tooth.
  • To cover a dental implant.
  • To make a cosmetic change.
  • To shield a root canal treated tooth.
  • To secure a weak tooth from breaking or holding together parts of a cracked tooth.

For these reasons, you can find different types of materials and combinations of dental crowns depending on your requirements.

Metal Crown

Gold, palladium, nickel, or chromium are the metals used to make a dental crown. The colour of the metal makes it noticeable when you smile or talk, and is not an ideal choice for visible teeth which are in the front. They are preferred to be placed in the back teeth so that they remain out of sight. Although they are low on aesthetic features, they are highly durable and can withstand the daily wear down caused by grinding or chewing. They also require less proportion of uprooting of any natural structure of the tooth compared to the other types of crowns. This is a less expensive option of dental crown material to choose from.

Ceramic Crown

Ceramic crowns for a dental crown can be all-porcelain or all-ceramic. This type of dental crown is translucent and is custom-made to match the natural tooth colour. Hence, this type can be aesthetically pleasing and nearly unnoticeable. The principal tooth and the filling materials determine the sealing ability of the dental crown. Dentists can design the crown to match the colour of the surrounding teeth and blend it in. They are however not as durable as metal crowns and can cause the teeth opposite the crown to wear down. The brittle nature of porcelain or ceramic causes it to chip more easily than metal or resin. You can choose ceramic crowns for the front teeth.

All-Resin Crown

An all-resin dental crown offers an affordable variety of tooth-coloured crowns. This dental crown made of composite material is an option to choose if you are looking for metal-free crowns. Over time, all-resin crowns can be subjected to fractures and break quicker than porcelain-fused-to-metal crowns. The highly polished surface of the composite crown wears out with tooth brushing and causes them to stain easily. It usually takes two visits to your dentist for placing the crown. The crown is customised in the laboratory to suit a patient perfectly. However, it is recommended to consider another type of dental crown since they wear out easily.

Porcelain-Fused-to-Metal Crown

Porcelain-fused-to-metal crown depict a natural tooth colour but are not as translucent as the ceramic crown. As the name suggests, the porcelain-fused-to-metal dental crown is a metal crown coated with porcelain material. The presence of metal is visible along the gum line which makes it rather opaque. The porcelain portion of the crown can also chip off or break because of the wear down with the teeth opposite them. On the contrary, the dental crown offers high durability. You can choose a porcelain-fused-to-metal crown for the front or the back teeth to take advantage of the strength the metal gives.

Zirconia Crown

This type of dental crown is made from zirconium and when placed on the tooth is non-identifiable from your natural set of teeth. Zirconia dental crowns are termed biocompatible because of their capability to integrate with the gums and function like a natural tooth. This dental crown is strong and can withstand corrosion, adding to its long life, which is unavoidable in other types of dental crowns.

Stainless Steel Crown

This dental crown is a temporary crown that is used until a permanent restoration is made. An entire tooth is covered with the crown, protecting it from decay – making it a preferable option for children. They also require lesser dental visits and are cost-effective. A stainless steel crown, like a metal crown, doesn’t have a cosmetic appeal to it but are durable.

You must understand that all the varieties of crowns favour the similar results. All the crowns vary in their cost and you should consider the cost factor that is convenient for your pocket. If maintained properly, dental crowns can last for a long time. Remember to brush and floss the crown just like you clean your natural teeth. Although, you can avoid needing to choose a dental crown by keeping up your oral hygiene and visiting your dentist at regular intervals.
