For years I've used a standard toothbrush.
I'll be the first to admit that I'm a bit of an over-brusher. My preference would be to brush my teeth about 5 times per day. I've always been that way, and I have really, really white teeth. So white that people routinely ask if I've had my teeth bleached. (not that there is a damn thing wrong with having your teeth bleached...i simply haven't) I think I've always credited my white teeth to my diligent brushing.
I also am a "hard" brusher, from what my dentist says. I brush too hard, and he can literally see grooves (with a magnifying glass) on my teeth. This was the latest news at my last dentist appointment. That, and the recommendation that I purchase a "spinning" toothbrush.
TEN uses a spinning toothbrush. So does mrs.mfc. I think lots of people use them. I have never felt the need. But, it seems that I am not to be trusted on my own with brushing. I cannot be relied upon to brush in smooth circles that will not grind my teeth to pieces.
I am now the proud owner of one of these....
