What are symptoms of a tooth that needs a root canal?

A tooth that needs a root canal often shows clear signs that the nerve is infected or inflamed. Symptoms can come and go, or they may get gradually worse over time.

Signs You Might Need a Root Canal

  • Severe toothache, especially a throbbing or pressure-like pain
  • Pain when chewing or biting down
  • Sensitivity to heat or cold that lingers after the source is gone
  • Gum or facial swelling 
  • Pimple-like bump on the gums (can indicate an abscess)
  • Darkening or discoloration of the tooth

If you experience any of the following signs, call Hu Smiles in Renton right away: 

  • Pain that wakes you up at night
  • Swelling that is spreading
  • A bad taste or odor near the tooth
  • Fever or feeling generally unwell

Why These Symptoms Happen

The pulp at the center of your tooth contains the blood vessels and nerves that keep the tooth alive. When decay, a crack, or trauma reaches this part of the tooth, bacteria cause infection and inflammation. A root canal removes the infection and saves the natural tooth.
