and i was wondering, are the results good? they use a blue light, and i wanted to ask if the results were good cause I wanted to try it
--------------------
I just saw one of those teeth whitening booths at a mall in Indianapolis not too long ago. I'm not sure how much I would trust a dental booth in the middle of a mall. For one thing, it cost $119. Second of all, as I was walking by, I heard someone ask the person working there if they did before/after pictures to see the comparison and the person said no. In a regular dentist's office, I could understand that, but in a booth in a mall, I would think they would be eager to market their product if it's that good. Me personally, I would just rather stick to paying out a lot of money to a dentist to get them professionally done (at least then I know they will be done well) or go buy some white strips at a drug store than fork out $119 of money I don't have on a questionable product. Hope this helps.
