The quickest, most dramatic results come from ZOOM! Professional Teeth Whitening. In less than an hour, your teeth can get an average of eight shades whiter. What we have found to be the safest and most effective methods are the dentist supervised in-office light activated peroxide gel or a molded dental take home tray to be used with peroxide prescribed by dentists.

For longest lasting results, it is ZOOM! in-office whitening combined with the take home whitening kit. The effectiveness of the professional in-office system and the professional take home systems in many cases is comparable, it's just that the in-office systems accelerates the process greatly and dramatic effects (in the range of 8 - 12 shades whiter) can be achieved for many people in only an hour or so. You can do the same thing or even get whiter with professional take home trays at home, but it would likely take a couple of weeks or more of use of the trays.
