Crowns are used to restore the tooth to its original shape, size, and strength after the cavity has deteriorated the tooth. It is a type of dental restoration that will improve the appearance of your smile as well as the strength of your teeth. The crown is a tooth-shaped cap that is made out of metal, porcelain fused to metal, resin, or ceramic/porcelain. A crown is needed when a large cavity has damaged a tooth. They can prevent teeth from breaking or replace a tooth that has already broken. Crowns are also needed when misshapen or discolored teeth need to be covered, to hold a bridge in place, or to cover a dental implant.

If the dentist feels that you need a crown, the first thing that they will do is prepare the tooth. The dentist prepares the tooth by removing some enamel so that there is room for the crown to fit properly. A impression is made so that a crown can be made to fit exactly the way it should. A temporary crown will be placed until the permanent crown is created. At the next visit, the dentist will cement the crown permanently.
The durability is a major advantage of getting a crown instead compared to other restorative procedures or having no treatment at all. A dental crown will last between 5 – 15 years. They do not need any special attention, but they do need good hygiene just like the rest of your teeth because there is still a partial tooth and nerve underneath the crown that is still alive and needs to be taken care of.
