I have a tooth that had a filling in it but the filling some how came out. I started having severe tooth ache on the tooth and got some temporary filling from walgreens. after applying the temporary filling, the toothache stopped and after awhile the temp filling came off. No more tooth ache but I now have a weird bump on my gums. It is above the tooth that hurt and only hurts if i press down on it. Any idea what this could be?
