Dental Crown Lengthening

When a tooth has a deep cavity, a crown and buildup are usually needed to restore the tooth. If the cavity extends too far below the gums, it becomes impossible to predictably make a crown that will last for any length of time. Performing crown lengthening where indicated improves the overall prognosis for the tooth.

What is Crown Lengthening?

Crown lengthening is a surgical procedure that is done when the tooth is too short to provide adequate retention for a restoration (usually a crown).

When is Crown Lengthening Necessary?

Crown lengthening nearly always involves removing and recontouring some of the bone around the tooth. This results in more tooth structure above the gums and smooth flowing gum contours. Not every tooth that needs a crown also needs crown lengthening surgery, it is only necessary when a deep cavity or crack is present.

Specific situations that you may need dental crown lengthening include:

  • To be able to keep a tooth that would otherwise be removed (decay under the gum line)
  • Provide gum contours that make the tooth easy-to-clean again
  • Improve the appearance of the gum line (in some cases)

Treatment Procedure

First, the periodontist will thoroughly numb the tooth or teeth needing crown lengthening. During this procedure, excess gum and bone tissue are reshaped to expose more of the natural tooth. After the procedure, your dentist can now prepare the tooth for a functional, long-lasting crown. As always, proper brushing and flossing is key to ensuring the maximum life of your new crown.

At times the tooth requiring treatment will require a specialist, called a periodontists, to examine and complete the treatment. Dr. Lisa Crafton will work closely with our periodontists specialist to review your treatment case, send necessary records to their office. Our office staff will help coordinate your appointments and help you understand your financial responsibility.
