Q: What is a crown?

A: A crown is a restoration that rebuilds missing tooth structure as a result of trauma, decay, or to improve shape, function, and aesthetics. It can make a tooth stronger when there is not enough tooth structure to support a filling. A crown can be placed over an implant, and can also correct a tooth with a congenital or developmental deformity.

Q: What is a crown made of?

A: Porcelain, or porcelain and metal, or porcelain and zirconia, or zirconia, or metal. The material used depends on the reason a tooth needs a crown.

Q: If I have a crown made, do I need a root canal?

A: No. If you need a crown, you do not necessarily need a root canal. However, if a tooth needs a root canal or has an existing root canal, the majority of the time you may need a crown. A tooth with a root canal may be more susceptible to fracture without a crown, and the crown minimizes the chances of further damage.

Q: How long will the crown last?

A: Like all restorations in the mouth, it depends on the condition of the tooth prior to the crown and the health of the surrounding tissue (the bone and gums). Habits such as grinding and clenching, and the practice of good oral hygiene can determine the success and longevity of the crown.

Brushing twice per day, flossing, and having regular checkups and cleanings will give your crown the best chance to last for many years.

Q: What is involved in a dental crown procedure?

Initially, a visual and radiographic exam (an X-ray) is done to evaluate the tooth in question. If the tooth needs periodontal or root canal therapy, this treatment is done prior to the crown. 

During the first visit, under local anesthetic, the tooth is prepared or reduced by the amount of porcelain or metal being placed over the tooth. Impressions of the tooth are then taken by using a putty-like material or scanned by a computer. Once the impressions are taken, a temporary crown is made to protect the tooth and surrounding tissue while the permanent crown is being made at a laboratory.

The following visit, the temporary crown is removed, and the permanent crown is cemented.
