It’s not your very favorite electric toothbrush, but this Sonicare 2 Plaque Control Electric Toothbrush is the same brand and would be a good way to dip your toe in the water of electric toothbrushes. This brush is specially designed to remove plaque, removing up to 6 times more than a regular manual toothbrush.
