Make sure they numb you and afterwards give you something for pain and you should be okay.
you don't feel anything while they yank them out. If you imagine what they are doing you may feel ill. Afterwards your recovery can be a piece of cake, or a living hell. If you get a dry socket you are in for a world of pain. <br />
When they tell you not to suck do NOT suck. If you dislodge the blood clot over the extraction it hurts like hades for ages.
If they use the right drugs you wont feel much at all.
Ask for plenty of anaesthetic and tell the dentist you're nervous. If he/she is good, they'll talk you through it step by step without the gory bits! Good luck...
I had my wisdom teeth pulled and it wasn't all that bad. They numb you first so instead of feeling pain you'll feel pressure.
