@SarahGen-- An ionic toothbrush may seem fancy or too good to be true but it works. I had my doubts about it too when I bought it. But after a few uses, I realized that this whole mechanism of positive and negative ions works. I highly recommend that you try this brush at least once before making up your mind about it.
The great part about the ionic toothbrush is that it doesn't only clean well, but it maintains clean teeth for far longer. I'm actually not as particular about cleaning my teeth as other people. I usually brush only once a day. But my teeth are doing great because the ionic toothbrush keeps them clean for a very long time.
I think that the toothbrush doesn't just attract the bacteria and plaque, it prevents them from coming back for a while as well. I don't think that I'm ever going to go back to a regular toothbrush.
