Crowns are often needed when a large portion of tooth structure is compromised either due to a cavity or after a root canal treatment. The dentist will fix it on to the tooth using a dental cement. Crowns are often used to improve the strength or appearance of teeth.
Getting a crown on your tooth typically involves two appointments. First one in which a tooth is prepared to receive a crown and the second one in which the crown is placed on to a tooth.
There are different types of crowns depending on the type of material used in their fabrication,
1. Metal crown
2. Porcelain fused to metal crown (PFM)
3. Zirconia crown
4. All ceramic/E-max crown
