This is no fake review...seriously. I have veneers on my 6 front teeth. I have gone through gum surgery (& if anyone reading this has had gum surgery, you know how your teeth are never the same). Soooo, in short almost every single one of my teeth was HYPER sensitive. Since the gum surgery, I've had to get my teeth cleaned every 90 days. It has been excrutiating. They have to numb me each time so I don't hit the ceiling. Horrible experiences. Well, I've been using Supersmile for approx 4 weeks and had my teeth cleaned today. NO NOVACAINE!!! You guys, if you have a sensitivity problem, this stuff really, really works. Oh, yeah...and it brightens your teeth too...even veneers :-) It is expensive, but a little goes a long way. And I don't know about you, but I'd almost pay anything not to have to be shot with novacaine every 90 days. I use this in conjunction with the whitening rods...I don't know if that's the "magic potion", but whatever it is, it's very cool not to have to stress out over a teeth cleaning.
