Great Product!
I love the use of the pen and just painting it on my teeth. Allows you to not touch your gums. I had no sensitivity and it doesn't taste bad at all. I didn't realize how hard it was to smile for 1 minute, seemed like forever..lol..I noticed a difference after my first use. I will definitely keep using this as a part of my daily regimen. If you're on the fence, just give it a try.
