I only said that cuz yesterday I got a tetanus shot (stuck myself with a rusty nail) but they also decided to do a blood test too just to get it out of the way this year.
*shudders* My parents and I got our blood drawn for free one time. I guess my body didn't like being stabbed so long, either. And then there's that time I had to have my eyes diluted at the eye doctor's...It was awful!, 'cause I nearly blacked out a couple minutes later.
It's actually much simpler, cheaper, and easier to use. You get a kit to get molds of your teeth at home and if the impressions are good, they make clear aligners for your teeth. It takes about 8 months for treatment (depending on how bad your teeth are) and you switch to a new set every 3 weeks that moves your teeth more and more.
You have to wear them all day and all night, but you have to take them out for short periods to eat or drink anything besides water. It costs about $1,200. Then you can buy unlimited retainers for $99.
