You don't have to be put to sleep for it. Not being put to sleep saves hundreds of dollars.

Mine were impacted too, but I wasn't put to sleep. The dentist cut through my gums and had to break the tooth to extract it, but it wasn't painful, just scary. There was a lot of pressure, but no pain. Just the simple freezing is enough.

Just ask for some Ativan to take to calm you down before. Bring music as a distraction.
