We use electric toothbrushes at our house, but I like to use a regular toothbrush in the morning. I have had my eye on one of these Zapi toothbrush sanitizers. The Zapi has an ultraviolet light to kill 99.9% of germs on your toothbrush. Stuff growing on my toothbrush is on of those things I don't like to think about.
You can even get them with smiley faces.
Or for kids... Hiyah Zapi or one you can put stickers on.
