doesn't make your teeth hurt. Updated review below
this is a daily strip then you gradually taper down. I had no discomfort with my teeth during or after and it does have a mildly pleasant clean taste. The strips do need to be removed after treatment like most of the store-bought ones I have tried. It was a little difficult to pull off but came off intact and not in pieces like some I have used.  Update !!  These things are the bomb !!! Been using a month and my teeth are so white I can see them in the dark
