Some electric toothbrushes these days can be pretty hi-tech. They can vibrate and/or spin back and forth thousands of times faster than your hands can move. Some even have smart phone apps to track how well you do!
It is still important to understand the basic value of brushing and flossing manually, but if using an electric toothbrush leads to brushing longer and better, then I'm all for it !
So whether its used to stimulate excitement in a young smile, or to help brush longer in a busy middle aged smile, or to overcome issues with dexterity or vision loss in an older smile; electric toothbrushes can mean better oral health for all.
