Excellent product that works!

My husband and I were actually shocked because we didn't expect it to work so well. He is a smoker and drinks coffee, I drink a lot of herbal teas that have stained my teeth. Within about 3/4 days we saw a drastic difference, most of the stains were gone and we looked so much healthier. I was a sceptic but I won't use anything else for stain removal (with bonus protection).
