Crowns Q&A

by B. Jeffrey Kay, DDS

What is a dental crown?

A dental crown is a protective covering that surrounds the entire tooth. Most crowns are made of durable porcelain or metal and porcelain that can be custom tinted to match neighboring teeth for a natural-looking result. Crowns are used to protect teeth used to support and bridge and to provide additional strength and protection for teeth that have had root canal treatment, and they're also used to protect and correct the appearance of teeth that have large, dark fillings, large cracks or chips, fractures or other damage, as well as deep discoloration or cosmetic defects that can't be treated with bleaching or veneers.

How is a crown applied?

Crown placement typically requires two appointments. During the first visit, a small amount of surface material will be removed from the tooth to make room for the crown so it fits comfortably and doesn't crowd or impinge on neighboring teeth and any existing decay will also be carefully removed and filled. An impression will be made of the tooth and sent to the lab where it will be custom crafted from porcelain and then tinted to match neighboring teeth. A temporary crown may be applied to protect the tooth while the permanent crown is being made. At the second visit, the temporary crown will be removed and the tooth will be carefully cleaned. Finally, the crown will be affixed to the tooth using a strong dental adhesive, then gently buffed and shaped for a comfortable fit.

What kind of care does a crown require?

Dental crowns are cared for just like natural teeth, with regular brushing and flossing and routine dental checkups to ensure the crown remains in good shape and the gums surrounding the crown remain healthy. Like natural teeth, a crown can be chipped or broken, so it's important not to chew on ice or hard candy and not to use teeth as gripping or prying tools in order to prevent damage to the crown.
