<s>[INST] I had a root canal and crown done to a molar several years ago to treat a tooth that had grown in without an enamel. Now 7 years later I have a painful lump on the boney part where the gums connect to the jaw. Its located directly below the tooth that has the crown. I am getting a throbbing pressure like pain in the bone of the jaw and feels as though there is pressure in the tooth. There is no swelling of my gums or face, no redness or any other symptoms. Just a painful lump on the bone conneccting the gums to the jaw.....do I have an abscess?? Or could it be something else? [/INST] Hello, Welcome Thanks for consulting HCM,    I have gone through your query, you have mentioned that you have undergone root canal treatment and crown placed on teeth several years back now you had pain dont worry may be there is Periodontal Pocket formation due to not proper maintain of hygiene , you do is consult dentist and go for investigations done    If there is pocket formation or Periodontal Abscess then go for sacling and currettage and if due to Periapical Pathology then RE -RCT should be done   Hope this will help you.   Wishing you good health Regards  Dr. Priyanka tiwari </s>
