what is the average cost of teeth whitening at the dentist office.?

i need an estamate cost.
--------------------
Er, the Zoom! 2 whitening, dentist-supervised one hour whitening, both top & bottom teeth, is $700 - $750. I think the other people who have responded so far are referring to the take-home whitening gel you can get from the dentist. A custom made tray cost my husband $100, I think? The bleaching gel was an additional cost. It takes a couple weeks, an hour a day, to get results.
