The tooth can be divided into two basic parts – the root and the crown. A cemented restoration that partially or completely covers the outside of the clinical crown is referred to as a dental crown.
There are many situations that require a tooth to be restored with a dental crown or an Inlay/Onlay:
– A large filling that involves half the width of the tooth needs to be covered with a dental crown.
– A root canal treatment leaves the tooth hollowed out and will need a dental crown to prevent fracturing.
– Teeth that have an unacceptable appearance can be altered using dental crowns.
– Dental crowns are placed over implants to close gaps from missing teeth.
Dental crowns can be made out of a gold alloy, other metal alloys, stainless steel, all-porcelain, composite resin or zirconia. Dental crowns are still susceptible to fracture and marginal cavities so it is important to continue treating them as you would your natural teeth and to focus on a good daily oral hygiene
