Hi. I saw an Endodonrist nearly 3 weeks ago after tooth pain/Infection. I had a root canal procedure earlier in the year on this tooth. The Endodontist recommended the root canal be done again so he did the procedure immediately. Pain virtually went away. However the guy area above this tooth has now become sore and a small blister has developed. I have started to take antiseptic mouthwash Curasept but is there anything else you would recommend? I took a course of Metronidazole before and during the treatment. Would you recommend some further antibiotic like Amoxicillin to heal the gum? Not sure what would cause the gum soreness. I’ve also seen a dental hygeniest.
