there was no pain at all.. at first my teeth were sore (not like they were suppose to be feeling GOOD) after getting braces on. the cost only depended on how long they'd think u'd need braces..depending on how bad your teeth were. they are very nice. the only reason why you would have to wait so long is because they're full, so just be patient and wait. it has only been 5 months since i had my braces on and my teeth have changed dramatically, i couldnt believe it!
