A Crown Came Off or Feels Loose

Sometimes the same crown goes back on. Sometimes what is underneath has changed and a new one is needed. What decides it is the condition of the tooth under the crown, not the crown itself.

Keep the crown — bring it with you, it is often reusable. Do not superglue it: the tooth needs to be cleaned and assessed first, and adhesives can make re-cementing impossible. Keep the area clean, avoid chewing on it, and call us. If the exposed tooth is sensitive, avoid very hot and cold food until you are seen.

What determines whether it can be re-cemented

Is the tooth underneath sound?
Decay under a crown is the most common reason a crown will not simply go back on.
Is any tooth structure attached to the crown?
If part of the tooth came away inside the crown, the plan changes.
Does the crown still fit accurately?
A distorted or damaged margin will not seal.
Is the tooth tender or infected?
Symptoms may need to be addressed before anything is cemented.
