I have almost perfect teeth and I only brush a few times a week hehe ultrasonic toothbrush, floss and mouthwash of course....in the early days of the net I found somebody that said that if you brush what they say you should you will totally ruin your enamel making you a ripe candidate for dentures....don't believe everything you are told ...these are the same nuts that are forcefeeding you flouride ....a toxic poison that causes cancer and dementia
