Which is better? Getting all 4 out; one is sideways impacted. I just went to the dentist to get some fillings done and they 'attempted' pulling the impacted one WITHOUT any anesthesia just numbing which was VERY uncomfortable and it just didn't happen. The referred me to a different dentist that does do anesthesia. Laughing gas is less expensive so I would rather do that but not if its going to be unbearably painful. Being put to sleep would cost more and that would be ideal don't know if I can afford that. Would the nitrous oxide help a lot or does it barely do anything is what I'm wondering? I'm so nervous to get this done! BLA!!
