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.
