A dental crown is a cap that covers a whole tooth to restore its strength, shape, and appearance. Crowns protect weak or cracked teeth, restore broken or heavily filled teeth, cover a dental implant, and can improve the look of a discolored or misshapen tooth.
What is a dental crown?
A crown is a custom cap that covers the entire visible part of a tooth above the gumline.
When you might need a crown
A crown can strengthen a tooth with a large filling when little tooth remains, protect a weak tooth from breaking, restore a tooth that’s already broken, hold a dental bridge in place, cover a dental implant, or improve a discolored or misshapen tooth.
Types of crowns
Common options include all-porcelain or ceramic (most natural-looking), porcelain-fused-to-metal, metal (gold or alloy, very durable), and zirconia. Your dentist recommends the best type based on the tooth’s location and your needs.
What to expect
Usually the dentist shapes the tooth, takes an impression, and places a temporary crown; the permanent crown is cemented at a later visit. Some offices offer same-day crowns made in-office.
Caring for a crown
Brush and floss as normal. The crown itself can’t get a cavity, but the natural tooth underneath still can — especially where the crown meets the tooth — so keep cleaning that area well.

Frequently Asked Questions
How long do crowns last?
Often many years with good care; over time they can wear, chip, or loosen and may need replacement.
Does getting a crown hurt?
The tooth is numbed for the procedure. Mild sensitivity afterward is normal and usually settles.
Can a crowned tooth get a cavity?
Yes — decay can start at the margin where the crown meets the tooth, so keep brushing and flossing there.
