So my husband Michael went for a root canal on April 12 and one extraction on April 13. He had the twenty hyperbaric treatments prior to them and 10 afterwards. We had thought everything was healing up all right although he did not have many follow �up dental visits scheduled with any of the four separate dentists involved in his care,. About 2 weeks ago he had some swelling again and he went back to his regular dentist and he told him that the tooth with the root canal was infected and the tooth is loose. He put him on antibiotics, the swelling did get better, he went back to the dentist this past Monday and he told him that it looked better, but still not totally healed. Today he woke up with a mouth full of blood. He really doesn't know exactly what is bleeding. He is scared and I am scared. He goes back to the dentist today in a couple hours. Any thoughts, reassurance, whatever???
