A dental crown is a tooth-shaped "cap" that is placed over a tooth, covering it to restore its shape and size, strength, and improve its appearance. Crowns are necessary when a tooth is broken or weakened by decay or a large filling, or when it needs protection after a root canal procedure. They can also be used to cover a dental implant, hold a bridge in place, or improve the aesthetics of a discolored or poorly shaped tooth.

When Are Dental Crowns Recommended?

Your dentist may recommend a dental crown for several reasons. These include protecting a weak tooth from fracturing, restoring an already broken tooth or a tooth that has been severely worn down, covering and supporting a tooth with a large filling when there isn't much tooth left, holding a dental bridge in place, covering misshapen or severely discolored teeth, or covering a dental implant. Crowns are a versatile solution for significant dental repair.

Types of Dental Crowns

Dental crowns can be made from several different materials, each offering unique benefits. Common types include porcelain-fused-to-metal, which provides both strength and a natural tooth-like appearance; all-ceramic or all-porcelain crowns, ideal for front teeth due to their excellent aesthetics; and zirconia crowns, known for their exceptional strength and durability. Gold alloys and base metal alloys are also options, particularly for back teeth where strength is paramount.

The Dental Crown Procedure

The process of getting a dental crown typically involves two appointments. During the first visit, the tooth is prepared by removing a small amount of enamel to make room for the crown. An impression of the tooth is then taken and sent to a dental lab, where your custom crown will be fabricated. A temporary crown is placed to protect the tooth in the interim. On your second visit, the temporary crown is removed, and the permanent crown is carefully fitted and cemented into place, ensuring proper bite and comfort.

Caring for Your Dental Crown

With proper care, a dental crown can last for many years. It's essential to maintain good oral hygiene practices, including brushing twice a day, flossing daily, and regular dental check-ups. Although the crown itself cannot decay, the tooth underneath can, and the gum line around the crown is still susceptible to gum disease. Avoiding hard or sticky foods can also help prolong the life of your crown.
