Hi cutie! You'll be okay! Your dentist should give you enough medication to make it painless. Don't worry! They'll ask you if the area is completely numb, and they'll give you extra medication until it is. I need extra all the time. :). Pay close attention to your aftercare instructions, and enjoy your healthy smile.
They will give you a shot first, which will sting a little; less if you can hold really still. Oddly, most of what you will feel when they "pull" the tooth is a "pushing" sensation. At my age, I have had several pulled; only one infected wisdom tooth decades ago hurt but not that much. Nor have I had trouble with aches afterward. Take the dentist's advice on how to care for the "hole" -- no straws, no smoking, no -- whatever else he/she tells you. That's only for about a week. He/she should have you come back in a few days to have the "hole" checked but that's nothing.
the only thing that hurts is the little shot they give you but that's more of a little pinch you will feel absolutely nothing you'll be asking when they will pull it and they will have already taken it out
If you can get gas, that will help with your anxiety and you can breath and relax. They will put some numbing medicine on first with a long cotton swab, so you won't even feel the shot. Just close your eyes or at our Dentist ,we can watch TV while they work on you. You will do fine... No worries...;)
