<s>[INST] I have swelling/a bump on the upper left side of my hard palate, above #14-15.  It is painful to the touch and hurts when I swallow.  Radiographs show no signs of infection.  It started 2 days ago and has not changed, It is just as big and just as painful, if not more. [/INST] Hi Dear, welcome to Chat Doctor. Understanding your concern. As per your query you have swollen bump on upper left side of palate which is painful and causing difficulty in swallowing is nothing just an irregular shaping of the hard palate bone. It is a palatal torus, which is a normal overgrowth of bone on the roof of mouth. Sometimes food or toothbrush can scrap the tender tissue stretching over the torus causing pain. If it is very near to tooth and gingival recession is there then it could be due to calculus deposits in and around tooth of that area. Need not worry. It is a self-correcting pathology if it is a palatal torus and will attain normal shape soon. If it is really troubling you then removal is the best treatment option in that case. Upper denture is also made to cover this torus area to prevent irritation and ulceration on it again and again. Visit dentist once and get it examined properly. If it is calculus related proper cleaning and scaling is required in that area. Antimicrobial mouth wash is required on daily basis. Once that area will be clean swelling will subside and your symptoms will resolve immediately. Hope your concern has been resolved. Get Well Soon. Best wishes, </s>
