I had braces for 3 years. When you first get them on they hurt. Take lots of tylenol, and try not to talk much. When you are getting your braces on, remember to stay patient. They will use this smelly disgusting adhesive to apply the brackets, and if your tongue touches it, then they have to start over. You'll get used to them in 2 weeks at the least.
i have them
they hurt like hell for the first few days - especially if you have really bad teeth.
prior to putting in the actual braces, you usually get separators, which make a gap in your teeth so they can put the metal bracket thing in. separators are hell.
after a few months with the braces, they usually give you elastics. now these are also hell. you put them in and they pull your teeth. i've gone through 1 year with braces, and i guess you just get used to them..
my friend only got a plate, cos his teeth were okay
