--------------------
White spots or brown spots may be developmental, which means that whitening will not affect the spot that its the spot will not go away with teeth bleach. If you have a brown spot thats developmental in origin, or due to a civity it will not change color, and may in fact stand out more if you bleach bc the rest of you teeth will lighten while the brown spot stays dark. On the other hand if you have a white spots that developmental, and you bleach the white spot may become less noticable bc the surrounding teeth are lightetened. Zoom price can rainge depending on speed. The one hour zoom can cost anywhere from 300 to 500. the take home weekender takes three days of use and can cost from 100 to 150 the results of both are the same and for many the take home the results are better bc sensitivity is controllable, with the one hour bleach its an all or nothing, if you stop treatment bc of sensitivity you lose the bleach that went un used, with the take home you can refigriate it and use it later and continue where you left off.
