I got my braces May 22nd, 2008. Monday night i got my power chains, NiTi's (type of archwire) and my elastc, on my left side.
I am supposed to have my braces for 2.5 years, but i read online that when you get your NiTi's this means your teeth are pretty straight.
Is this true? and how long do you think i'll have my braces on for?

Thanks.
I will add deatails if needed.
