Question about whitening strips..?
As I sit here with whitening strips on my teeth - which I just bought - I was wondering - why are there so many choices out there for the same brand - we have the classic which are $20- and the 5 minute ones which a $35, and the ones I got are premium - $30-
why all the choices, and do some work better then others???

I am an expert on the crest whitestrips...I use them about every 6 months...the orginal classic box is what i use...yes, it may take a few days longer but it's cheaper and it works just the same!!!! and the boxes do have experation dates on them and a year a half needs to be thrown out.
