How long does tooth pain after root canal last

Mild tenderness after root canal treatment can occur as tissues around the root settle, but worsening or persistent pain needs review.

Root canal treatment removes inflamed or infected pulp from the canals, cleans and shapes them, then seals them. The ligament and bone around the root can remain irritated after the procedure, especially when the tooth is pressed or bites.

Follow the treating dentist’s instructions, chew on the other side until the final restoration is placed, and use only pain medicine that is appropriate for you and taken as directed. Contact the practice if your bite feels high, because an uneven bite can keep the tooth sore.

Contact a dentist promptly for increasing pain, swelling, fever, a bad taste, pus, or a tooth that feels too high when you bite. Urgent care is needed for spreading facial swelling or difficulty swallowing or breathing.

Ask whether the tenderness fits normal healing, whether the bite needs adjustment, and whether the canals and final seal look satisfactory. Ask which symptoms indicate a missed canal, reinfection, crack, or another tooth problem.
