I had an apicoectomy on 2/17 was on antibiotics for 10 days. stitches fell out 10 days after procedure. three weeks ago i noticed a bubble on my gumline where i believe the incision was. worried its an infection and ive had for 3 weeks. no pain?

You should make an appointment to see your dentist next week for easing your concern although active infection is unlikely without pain. Take care.

The General Dentist or specialist Endodontistg that did hoursurgical procedure is responsible for o9ur post-surgical care. There are infection and non-infection causes for a "bubble." Please see your practitioner.

The incision for an apicoectomy is made at the tip of the root of the tooth involved. A bubble at gum line could be an infection from next tooth or same tooth. It could be a periodontal[gum] infection, that has nothing to do with the root canal tooth or it could be from the root canaled tooth where the infection hasn't subsided. See your dentist or specialist for updated condition.
