Dental pain guide
6 min readPain under a crown
Pain under a crown can be linked with the tooth, gum, bite, cement or the crown itself. A dentist needs to assess the cause if symptoms persist or worsen.
A crown covers a tooth, but the tooth, gum and surrounding tissues can still develop symptoms. Pain may be triggered by biting, temperature, flossing, gum swelling or no obvious trigger.
Pain under a crown does not prove that the crown has failed. A dentist can assess the tooth, crown edge, gum, bite and any signs of infection or decay.
