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.
