A. I understand that you are nervous and afraid of the dentist- but as I’m sure you are more than aware of the fact that this problem is not going to resolve by ityself.You really do need to see a dentist for this matter.The dentist will not put you through any unneccesary pain. they may give you some antbiotics to help with the swelling initially. It sounds as though the tooth is infected. If this infection (lump)is not treated, it will get bigger and more painful. It could also spread and complicate matters.Please gather up some courage and visit your local dentist.There are also many facilities that provide treament under sedation for very nervous patients. You can enquire about ths.Remember, we are here to help you.Good Luck
