Interesting and thanks for sharing. Though, it does raise a question based from my personal experiences. Is it really the brushing techniques that stop cavities, or, is it the medium/cleanser used to clean the teeth? Quick story about me then maybe one about one of my clients. For me, I did the brushing 3 times a day using the "rolling method" from the time I was a little ankle-biter up until just a few years ago. (I am 29 now). During that time, cavities would inevitably develop and grow larger over time. I had 3 teeth pulled. I couldn't figure out what I was doing wrong. I was rinsing and brushing with ADA approved pastes/mouthwashes in addition to flossing. Still, I was getting cavities. I didn't really each much sugar. Then a few years ago, I ran out of toothpaste in a house full of impoverished hippie types. One of them suggested that I brush with Baking Soda and rinse with Peroxide. I started doing this daily. Within 2 weeks, the toothaches that I would experience with my cavities subsided. Soon after, they rarely ever came back even if I was chewing hard food like a pig. Also, the cavities stopped getting bigger. They have remained the same size since then and toothaches rarely bother me now. With Toothpaste and mouthwash, I would deal with toothaches weekly and daily sometimes. It was horrible. Thanks for sharing, btw. I will share my client's experience in a separate comment.
