What to Do If a Crown Falls Off

A crown that comes loose or falls off can be startling, but it’s rarely a true emergency. If it happens to you, a few simple steps will protect your tooth until you see your dentist.

First, find and save the crown

If the crown comes off while you’re eating, take it out of your mouth right away so you don’t swallow it. Rinse it gently with water and keep it in a small container or sealed bag. Bring it with you, since your dentist may be able to reuse it if it’s undamaged.

A swallowed crown usually passes on its own, but let your dentist know. If you’re coughing, wheezing or struggling to breathe, you may have inhaled it, so get medical care right away.

Protect the tooth in the meantime

The tooth under a crown has been reshaped, so it may be sensitive to hot, cold or even air. Until you’re seen:

  • Chew on the other side of your mouth

  • Avoid sticky, hard, hot or cold foods

  • Brush the area gently to keep it clean

  • Take an over-the-counter pain reliever if needed

Pharmacies sell temporary dental cement that can hold a crown in place short-term. Never use household glue, which can damage the crown and your tooth.

Call your dentist promptly

Book an appointment as soon as you can, ideally within a few days. An uncovered tooth is more vulnerable to decay and damage, and nearby teeth can start to shift. Call right away if you’re in pain or the crown is on a front tooth.

What happens at your appointment

Your dentist will examine the crown and the tooth underneath, often with an X-ray, to find out why it came off. Common causes include worn cement, decay under the crown and teeth grinding. If both are healthy, the crown can often be cemented back in place. If not, you may need treatment for the tooth and a new dental crown to protect it.

Help your crown last

Brush and floss carefully around your crown, avoid chewing ice or hard candy and keep up with regular checkups. If you grind your teeth, ask about a night guard.
