Had abscess tooth about month ago for 2nd time, dentist advised meds and then root canal again. Has been one month since root canal, swelling is back, same as always everytime under the eye. The nerve in my mouth is sore but not the capped tooth. Should I see same again or does this sound like medical doctor needed. Tooth is a cap if that matters. Tooth has never hurt, but swelling always appeared later.
Hi. Thanks for the query. It looks like you have reinfection below the root tips of your root canal treated tooth and due to Infection and pus formation there is swelling. The other cause can be decay in adjacent tooth that might have become non-vital causing Periapical abscess. As the nerve inside the root canal treated tooth is already removed during root canal treatment therefore you do not have pain in the tooth. So my suggestion is to further get it confirmed by an x-ray of the tooth that is already treated and along with it the teeth next to it should also be covered under x-ray. If there is Infection in root canal treated tooth then first a script of antibiotics like Augmenting will be advised to see if the infection resolves. If it still does not resolve then extraction should be done as tooth is already root canal treated twice. If any adjacent tooth is decayed then rot canal treatment is advisable. Hope this helps. Regards.
