Whats the cheapest and safest way to whiten teeth?

i wanna whiten my teeth like 8 shades, but i dont wanna pay $800.00 plus dollars, theres gotta be a better way???
anyone know of some reliable product that can achieve this result without costing an arm and a leg????

thanks

First I would recommend that you consider having a dental cleaning and exam. If you have buildup (tartar, plaque, stain) the whitening process won't work that well. The crest whitestrips work well and are probably your lowest cost alternative. We sell them in my office ($75.00) and they are 3 times stronger than what are sold at drugstores and there are 3 weeks worth. I like them because they work better and if you are happy with how they look 1/2 way thru the process you just hold onto the rest and you have more to do a "touch up" 6 months later. Good luck!
