I love Supersmile products. I've ordered them thru QVC and it's not that expensive. I love the toothpaste and the whitening accelerator. You use both at once, just a small pea size amount on a dry toothbrush. I got a sample of the gum with my order. The inventor of Supersmile is-Dr.Smigel.. I hope I spelled that correct. He's the inventor of so many dental procedures.
