I've had braces before. to be completely honest, I have.. & well in my opinion it hurt for about 7 seconds. Just 7, but then I just thought "it'll be over soon" & it really helps you with a better smile. Braces are good for people :) the pain doesn't really hurt once you get used to it. even in 5 seconds, it's like "doesn't hurt". but, that's my opinion. it depends on personality :)
the first night yes like crazy. but after awhile you get used to them and it doesn't hurt unless your orthodontist tightens them which he has to do every once and awhile. just brush your teeth/keep them clean
at first they hurt... a lot :/ especially if you get an extra things to straighten your teeth... but the good thing is it doesnt hurt as much with pain pills and it's only pretty painful for about the first week... otherwise you'll be fine:) some people are more sensitive than others but as long as you have a good attitude about it all you'll do just fine !
They hurt, but only for a few days after you get them put on, and every time they tighten them. I got braces about two weeks ago, and they hurt for over a week. I couldn't even chew any food, so I just ate soup. They feel a lot better now, they don't hurt, and you get used to them after a while. Hope this helped.
