A crown fits around a tooth that has been shaped. It may be discussed when the tooth is extensively damaged or a large existing restoration is no longer adequate.
The reason comes before the material
The first decision is whether a crown is needed at all. The condition of the tooth, remaining tooth structure, gum health and biting forces guide the choice of restoration and material.
What happens during treatment?
The tooth is assessed and prepared, and an impression or scan records its shape. A temporary restoration may be needed. The final crown is checked for fit, bite and appearance before being secured.
Risks and limitations
Preparation removes tooth structure and cannot be reversed. Sensitivity, changes in the dental nerve, decay around the margin, gum problems or damage to the crown can occur. Further treatment may be necessary.
Alternatives and maintenance
A filling or an onlay may preserve more tooth structure where suitable. Another crown material may also be appropriate. Discuss the benefits and limitations of each option, along with cleaning and regular review.
