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

    I had a really bad coffee stain on my front teeth. Had tried the crest ones for a while but they weren’t helping. My hygienist did some treatment and told me it’ll probably come back because of the texture of my teeth, but told me to use the crest ones a few days ahead of a special event if I wanted a touchup. Stain came back.

    Went to the dentist for an unrelated issue and my dentist noticed the stain, literally filed down my tooth in like 2 seconds and for free, and the stain has never come back again, lol.

        In that case probably not for everyday use then , or just use sand. But I’d think that there is also some chemical action that makes it very effective against tea and coffee stains

    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

    Crest 3D strips work well, but do not fall asleep with them in… I did that by accident, swallowed one of the strips and woke up in such excruciating pain I had to crawl to the bathroom and puke. Just as heads up
