My gum is swollen just under my moler.  The top has one white patch, but it isnt red all around like some of the photos I have seen.  I had it before my last cleaning and my dentist said it was likely just trauma from chips or something, after taking an ex-ray.  He said it should clear up in a week or two, but now it has been a month.  It is slightly tender, but not to bothersome.
Hi. Thanks for the query. As per your complaint pain and swelling of the gum under a molar can be due to either deep infection in the gum due to deep impaction of any food debris in the gums or can also be due to decay in the tooth causing infection below the root tips. If the gum swelling is not reducing you should consult a Periodontist and get evaluated. As of now you can apply antiseptic ointment like Chlorohexidine over it along with numbing gel containing Lidocaine. Do warm saline gargles. Further treatment can be planned after examination by the Periodontist. Hope this helps. Regards.
