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

    I just use the whitening toothpaste but I don’t really notice a difference after using it for a couple of years now. I just keep it since I’m so used to it now.

      whitening toothpaste has the same active ingredient as regular toothpaste. some will have peroxide, but you would need to brush your teeth for significantly longer than 5 minutes for it to start working
