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

      note: from what I remember reading a while ago, this works because it scrapes your teeth, which slightly files them down. it’s like using using loose sand paper.

        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
