Hard bump dentist said was not dental

About a year ago, I started getting terrible sinus type headaches and numbness in my upper teeth, front. I found this hard bump under my nose, right aat and slightly above my gum line. I went to dr who ordered a ct scan (no contrast) and told me to see a dentist. The dentist did an xray and said it was not dental but that that area was generally benign. The ct scan (which turned out to be of my sinuses) did not "pick up" the lump. The dr sent me to ent who said the pain was probably tmj and that the lump was discovered and probably had always been there. The headaches/nose/eye pain continued, then I started getting swelling in my face and blurriness in my right eye. Then, the lump began growing, twice its original size and now extends down below gum line and is a softer bump down there. I made an appt with oral surgeon (which won't be for a while)- I wonder if I should go back to another dentist for second opinion?
