Treatment recovery guide
6 min readAfter root canal treatment
After root canal treatment, tenderness can occur. Contact the treating practice if pain is worsening, swelling develops or a temporary restoration feels loose.
Root canal treatment can leave the tooth and surrounding tissues tender. You may also have a temporary or final restoration that needs protecting until the planned care is complete.
Your treating dental practice is usually the first contact for concerns because it knows the tooth, treatment stage and planned review.
