I had awful tooth pain about 4 weeks ago..went to emergency dentist who couldn't locate exact tooth...had X-rays. Forward to now and I developed an abscess right up top of gum over my first molar towards front. I don't want root canal so was ready to have this tooth out, lovely dentist said it may be as the filling has failed and if we replace filling it may fix it. Has anyone had success with this? I was just ready to have the tooth out...
