What is a dental crown, and when is one needed?

A dental crown is a custom cap that covers a tooth above the gum. It restores the shape of a tooth that is cracked, worn, heavily filled, or weakened after a large cavity. The crown is made outside the mouth, then fitted and attached to the prepared tooth.

When a crown is considered

  • A crack or break that a filling cannot hold together
  • A large filling that leaves too little natural tooth
  • Wear that has shortened or flattened the tooth
  • A tooth that has had a root canal and needs coverage
  • A tooth that is the support for a bridge, which is a different service from a single crown

A crown is not the default for every cavity. A smaller defect is often repaired with a filling. The exam and an X-ray show how much healthy tooth is left and whether the nerve inside the tooth is involved.

Which teeth this program covers

The $799 program is for an eligible single tooth that can take a strong, tooth-colored ceramic crown. Wisdom teeth and second molars are not included. Implant crowns are not included. A case that is mainly about smile design, or that needs an esthetic E.max crown, is a different visit and a different fee.

The dentist can also decline treatment when the remaining tooth has a poor outlook. That decision is made at the exam, not from a photo or a form.

This is general information, not dental advice and not a diagnosis. Offer terms for the crown program are confirmed at a consultation.
