Reasons for a Dental Crown

A dental crown is a type of dental restoration whereby a tooth-shaped "cap" is cemented over a natural tooth, covering the visible portion of the tooth. The crown improves the appearance and returns shape, size and strength to the tooth. There are several reasons why a dental crown might be required.

Tooth Restoration

• A tooth that has already been broken, chipped or severely worn down may require a crown. Unlike a cavity, which can be cleaned and filled, a filling cannot be used with a chipped or broken tooth. Left untreated, a damaged tooth causes pain and discomfort and will lead to tooth decay. A crown covering the tooth will protect the tooth and prevent further damage.

Tooth Strengthening

• As a preventive measure, a dental crown may be used to protect a weak tooth from further trauma. Teeth that are breaking or cracked can be held together by a crown. If a crown is not installed the tooth may continue to be degraded and cause more expensive and time-consuming dental work later.

Dental Bridge Anchoring

• A dental bridge is used to replace a missing tooth or teeth by joining them permanently to adjacent teeth. If the adjacent tooth is not strong enough to hold the bridge in place, a dentist may recommend crowning the weaker tooth to successfully install the bridge.

Large Filling Protection

• A tooth that has suffered from decay and had a large cavity filled may require a crown. A large filling that that covers most of the tooth may crack under pressure, as the filling can act like a wedge. To support the tooth and cover the filling, a dental crown may be required.

Dental Implantation

• A dental implant is a titanium "root" inserted into the bone used to replace missing teeth by supporting dental restorations that resemble a tooth or a group of teeth. The "root" resembles a screw that must be covered with a dental crown.

Aesthetic Reasons

• A dental crown may be requested for aesthetic reasons. Teeth that are misshapened, too small or severely discolored can be hidden from sight with a crown. Actors and politicians have been known to cap their teeth purely for cosmetic reasons.
