    Probably because they are from canada, seller seems legit and has loads of positive feedback so I would say they are genuine.

    Bought some myself thanks

    Are there likely to be custom charges?

    I meant the strength! ;-)

    Id love to have whiter teeth but Im so weary of trying these. I do have sensitivity at times and notice alot of the reviews say these can make them very sore and sensitive.

    I've used them. They definitely made a difference.


    The downside is that my teeth were extra sensitive then, and they are not normally! Worth the little pain for a few days for nicer teeth IMO X)

    Did the sensitivity wear off?

    Once I stopped using them yes. It did however gradually get worse while using them.

    Maybe you should try them a few times, if you don't get on with them then its not much lost.

    It something I really want to try but Im worried incase it damages my teeth.

    Crest Whitestrips Supreme Professional is the highest strength (at least they were last time I bought them, nearly a year ago). I tend to use them a few days at a time, as a freshener, so I don't do the full course. Definitely recommend them. Probably best to do it when you have some alone-time, though, as I tend to "drool" with it in my mouth (not a pretty sight).

    Would I need to use many of these before I notice a big difference?

    I suppose it's a case of how badly stained your teeth are in the first place, but my boyf has/had quite bad nicotine stains and he definitely noticed an improvement with the first 30 minute session of Supreme Professional Strips. A few days should see a good change.

    I get sensitive gums using it myself and only do it for a day or two as a top-up (I have a Philips HealthyWhite Sonic toothbrush and that does a good job at keeping stains away: I don't smoke but I'm a caffeine addict (_;)).

    I have used the Crest Express 3D White ones (bought as I thought they'd be similar, they were used for a shorter session each time, can't remember the variety) but they were nowhere near as good.

    Yahoo! Answers has two 3D Whitestrips varieties as:
    Crest 3D Whitestrips Professional Effects
    14% Hydrogen Peroxide
    Prices : $38.69 / 42 Pouches

    Crest 3d White 2-Hr Express Whitestrips
    17% Hydroxide Peroxide
    Costs : $32.30 / 4 Count


    So I'm a bit confused myself! These ones supposedly have a slightly higher % content than the Supreme Professional Whitestrips (though higher peroxide % means more sensitivity). Perhaps all the 3D versions are to be used for a shorter length of time (?).
