Which dentist office teeth whitening procedure to get? Zoom 2 or Opalescence Boost?

I'm confused on if I should get Zoom whitening for $400 with customized take home trays also, of pay $150 for the opalescence boost with un-customized take home touch ups. I'm leaning towards opalescence boost because of the price and since I'm a working student and the money could be used otherwise. Thanks guys

Opalescence Boost. You will have the same teeth whitening results whether you have professional teeth whitening In-Office or teeth whitening at home by yourself. This is because whitening teeth with peroxide is simply a function of the cumulative exposure of the person's teeth to the whitener. Using a low concentration peroxide over a series of individual treatments at home by yourself or a much higher concentration of peroxide over a much shorter time frame In-office can both be expected to produce the same result. After teeth whitening treatment, you will have on average 5 - 10 shades lighter. Choose the cheap of course. the site give me a lot of help, u can visit it. http://www.teethwhiteningbest.com/teeth-…
