Tooth Extraction

I had my tooth pulled out today. I got so nervous about the entire procedure. I chose the laughing gas instead of the IV. They said it is safer than the other drugs. I felt pain when the dentist injected the novacaine into my gum. Then I started to feel the numbness in my jaw. My lower wisdom tooth was tricky; he drilled it. I felt the pain when he did it even though I had my numbness; I don't really know why. But my upper tooth was fine; it didn't hurt when he pulled it. And it was very quick, just like the wink of an eye. After that I stood up and tried to spit, then the assistant saw me; she gave me a caveat, telling me not to spit because it would be dangerous. It could cause more bleeding. I have to wait till tomorrow, then I would be able to do it... When I got home I took a pain reliever just in case the novacaine wore out. I hate those pills, they make me dizzy.
