Review on ARM & HAMMER Spinbrush PRO Clean Medium REFILL - 2 Replacement Heads - Medium Bristles - Enhanced for Battery Powered Toothbrushes by Jessica Burns

I can't say enough good things about the arm and hammer toothbrushes. They have a round head and a brush that moves up and down. You can't lose with the rotating arm and hammer brushes. They are such a reasonable price. My hygienist told me to dry the brush first to get to the tarter. Then add toothpaste and shake off any residue. If you use good toothpaste, DO NOT rinse your mouth. Keep fluoride working against tooth decay. It really works. I like the ability to change attachments whenever I want. That's great.
