How long after an Apicoectomy should the tooth be sore? I know I will feel some sensation in the tooth but when my tongue touches it it is still really sore. It has been 3 weeks. It still hurts, not as strongly as it did before the apico, but it still hurts. It has a small pulse and I was put back on antibiotics again last week because it was hurting a lot. What's the next option and how long should I wait to see if it's still healing or if there is something else going on?
