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

      I think it’s the pro-whitening (ironically) one these days, one of the thinner black models. I’ve had to replace the handles occasionaly over the years but much cheaper in the long run than dealing with cavities, etc.
