Well long story.........Went to get a tooth pulled , didnt happen at that office , went to where I was referred. Oral surgeons office. I have been stuck so many times, I feel like a pincushion. I finally got hysterical with tears after the last I.V. stick and I do NOT get hysterical (I was shaking all over and my hands were cold) and they couldn't knock me out , so we finally agreed on laughing gas and more sticks in the mouth and got it removed in pieces. The decay was in my nerves. NO way I was coming back home without it taken care of. I have been through the wringer today . So glad I didn't get anethetized You may never come back from that one !
