You might need a root canal if you experience:
- Severe tooth pain when chewing.
- Prolonged sensitivity to hot or cold.
- Swollen or tender gums near the tooth.
- Darkening or discoloration of the tooth.
- A pimple-like bump on the gums (abscess).
- Deep decay or trauma to the tooth.
Your dentist will confirm the need with an exam and X-rays. Early treatment can save the tooth and relieve pain.
