How much does professional bleaching cost for your teeth?

I don't smoke or anything. How much is it to get your teeth whiten? Prices for all types please if you can and thanks.

It costs about 600.00 for one hour bleaching at the office. But I sugest that you do the take home bleaching trays which is about 250-300$, and you can bleach while watching TV at home and as many times per day as you want. Also, it has the same effect as the one hour bleaching that is much more expensive.
