Hi holly78711,
My sister also had the same problem. She too had an aching tooth and bleeding gum. She refused to have food when it was severe. We consulted a doctor in Centenary Dental in Scarborough. Doctor told us that improper dental hygiene had led to the problem. Bacteria accumulates in your gums which results in swollen and bleeding gums. She had a condition called GIngivitis which has worsened the problem. It is better and safe that you consult a doctor immediately because In some cases, it may lead to tooth loss also.
