Solid product for whitening and likely remineralizing
It's hard tell if this pen is remineralizing my teeth, as I wanted. Been using for over a month now, and my teeth are whiter. Sometimes, just after using it, they seem to be glowing. I now only apply it once a week. For all the research I've done on whiteners and remineralizers, this is the best product available. And, it's ingredients are much better than others. I also have sensitive teeth and have had absolutely no sensitivity with product.
