Last year I tried out this electronic toothbrush..a brand called Oral-B. It has self rotating brushes. They're a bit expensive, but well worth it. It helps get the plaque in the back of my teeth that a regular toothbrush can't. And it doesn't make my gums bleed so much. Which is a Plus!! This Oral-B toothbrush runs on batteries and has replacement brushes. Unfortunately, the replacement brushes don't come with the toothbrush when being purchased. It's sold separately. The only problem with this product is when the toothbrush needs to be replaced, there is this little pick that you use to take...
