I buy my toothbrushes in bulk and change them out about every month or so. I use a 'manual' toothbrush for two reasons. I like to brush my teeth at home but I also brush my teeth at the gym and have one in my desk at work just in case I need to brush them during the day. (the cost for three mechanical ones would be crazy). Ok this may seem excessive but when you get old you worry about them falling out. :lol:
The other reason is because I use to use a really nice rechargeable and the vibration of the spinning action actually bothered my teeth and got me to wondering about the damage that can be caused...increase in hairline cracks, shaking fillings....plus it was a shared toothbrush (different heads of course) and the other person got it in the agreement.;)
