I always had great teeth and never needed braces. However, as I've aged, my teeth have shifted and crowded. I am 2.5 months into a 9 month plan. I feel things changing, and believe it or not, I LOVE the feel of the Invisalign on my teeth. To be honest, I've been totally anal about my teeth care now. I figure, 1) $5,000; 2) my smile is part of who I am; 3) I want to keep my teeth. Here is my daily routine, and my teeth and gums are LOVING it: Morning - Brush teeth and brush Invisalign trays (since they're on 22 hours a day, they need to be clean and germ free) Day - Brush and floss and rinse the tray each time. Dinner - Soak the trays in Polident. Brush, floss, gargle with Listerine, brush the Polident on the trays. A great side affect is that I've lost 15 pounds since I'm not munching all day long.
