I had a major tooth ache starting on Monday, I bought sesodyne lastnight and used it.  The tooth is not hurting near as bad but I now have major pain around my gums.  It feels as though I have sores on my gums but when looking at them they look fine.  Could I possibly have an infection in my gums or just a cavity in my tooth?
Hi. Thanks for the query... As per your complaint if the symptoms started with a major toothache then it is most probably due to deep decay in tooth and if the infection progress below the root tips of the tooth then it can cause pus formation and swelling, pain and pus in gums too. I would therefore suggest you to consult an Oral Physician and get evaluated and get an x-ray of the tooth done. In case if tooth is decayed then Root canal treatment can be done followed by a course of antibiotics and anti-inflammatory painkillers. Also localized scaling to remove Infection in the gum around the tooth and gum paint massage can help. Hope this information helps. Regards.
