Crown Failure

“A loose, broken, or lost crown leaves your tooth unprotected. Prompt care can protect the tooth underneath.”

If Your Crown Comes Off

  • Keep the crown and bring it with you. It can often be re-cemented

  • Rinse gently with warm water

  • Avoid chewing on that tooth

  • Do not use super glue or household adhesives

  • Call us as soon as possible

Why Crowns Fail

  • Decay under the crown: the most common cause

  • Worn-out cement: the crown gradually loosens

  • Grinding and clenching: overloads the crown over time

  • A crack in the tooth underneath

  • Age: all dental work has a limited lifespan

Warning Signs

  • A loose crown

  • Bad taste or odor around it

  • Sensitivity to hot, cold, or biting

  • A dark line or gap at the gumline

  • Chipped porcelain

Treatment

  • Re-cementation: if the crown fits well and the tooth is healthy

  • New crown: if there is decay, damage, or poor fit. We place a temporary crown while the new one is made

  • Root canal treatment: if the nerve is affected

  • Extraction and replacement: if the tooth cannot be saved, with a [Dental Implant →] or bridge

Dr. Kim looks beyond the crown to understand why it failed, including your bite, grinding habits, and gum health, so the next one lasts longer.

A failed crown is a problem worth fixing promptly.
