How long does pain of root canal last

Root-canal tenderness usually improves over several days, but pain that worsens, persists, or affects your bite needs review.

Root-canal treatment removes inflamed pulp from the pulp chamber and canals, cleans and shapes them, then seals the space. The tissues around the root can still be irritated by treatment or by biting pressure while they recover.

Use the prescribed medicine exactly as directed, chew on the opposite side, and keep the temporary or permanent restoration intact. Do not place aspirin directly on the gum, and contact the treating clinic if your bite feels high because a small adjustment may relieve pressure.

Seek prompt care for facial swelling, fever, difficulty swallowing or breathing, a bad taste with drainage, or pain that is worsening rather than easing. Contact the dentist if the tooth feels too tall when you close your teeth or if symptoms return after improving.

Ask whether the pain is coming from normal inflammation, a high filling, a missed canal, a crack, or infection around the root. Ask what symptoms should trigger an examination and whether the final crown or restoration is due.
