About seven years ago I bought my first electric toothbrush and since then have never looked back at ordinary toothbrushes. Even when I am on the road I take along an electric toothbrush for travelling that operates on batteries. I really like the way is polishes and cleans my teeth without me having to do much at all. Also I find that it massages my gums nicely. They are strong and healthy, which I attribute largely to my electric toothbrush. What do you prefer?
