Hi Dear, Understanding your concern. As per your query you have symptoms of tooth pain and burning sensation on the roof of the mouth which seems to be due to high contact points after filling of tooth and whenever both teeth meet during biting of food it leads to pain and sharp edges causes burning sensation pain. Need not to worry. I would suggest you to - Do not eat hard food from that side and try to eat from other side. - Do warm saline rinses. - Apply cold compresses. - Take ibuprofen (if not allergic ) or acetaminophen for pain and swelling. Visit dentist once and he/she may examine physically and order X-ray to rule out other cause like residual infection and can trim off sharp edges and if it is due to residual infection filling needs to be redone. Hope your concern has been resolved. Get Well Soon. Best Wishes, Dr. Harry Maheshwari
