A dental crown (dental cap) may be needed when at least one of the following occurs:

- To protect a weak tooth (for instance, from decay) from breaking or to hold together parts of a cracked tooth.
- To restore an already broken tooth or a tooth that has been severely worn down.
- To cover and support a tooth with a large filling when there isn't a lot of tooth left.
- To hold a dental bridge in place.
- To cover misshapen or severely discolored teeth.
- To cover a dental implant.

The advantage of using pure porcelain is that the crowns are near identical in color to the existing colors of the patient's teeth, making it nigh on impossible for others to discern a crowned tooth from a real one. A dentist will match the color of the crown to the tooth color already in the mouth, and then they will place an order with a lab to create the tooth with the perfect color and shape, taken from the previously mentioned mold, and patients are very happy with the results, and their new smile.
