Just wondering if the ones they sell at the stores work and if so, which brand(s) worked for you.

    Yes.

    Even the generics work.

    Just read the labels, see what they use and concentrations, so you can change brands if one makes your teeth hurt (higher peroxide concentrations can do this for people who are sensitive).

      It also will burn your gums if you don’t trim the mouthpiece carefully around your gum line. Take your time when molding and trimming.

        eh, it’s bad for your teeth if you overuse or use too high a concentration of peroxide, but I think the line between actually getting your teeth white and using too much is pretty thin
