From what we've heard, Zoom! Teeth Whitening takes less than an hour and it really works! In short, a whitening gel is applied to your teeth, then the Zoom! lamp is shined on your teeth, and Zoom! - your teeth will end up an average of 8 shades lighter. The procedure will likely run you anywhere from $600-800. Of course, consult your local dentist first! For more information: http://www.zoomnow.com/index.php.
