@tanglewooddentist: We're giving away a tube of the toothpaste Dr. Lawnin's using right now. Follow us and comment on this post for a shot at it. We'll pick a winner in about a week. It's Mouthology's 3-in-1: 10% nano-hydroxyapatite, xylitol, sodium bicarbonate, no SLS or CAPB. He's been using it for about a month now and likes it enough to actually say so. Minty, not chalky. Even passed the "does my breath still stink" test at home.
