The Brush-pick is a toothbrush with a built in plastic pick in the back. The Brush-pick makes it easy to get everything out of your gums and teeth. Are you ever not able to get food out of your teeth with only the brush? The back of the brush has a small sharp tip that you can put between your teeth or gums to get food out that you can’t get out with the regular brush. The entire toothbrush itself isn’t too big and is easy and comfortable to be holding. The small size of the comb at only 5 inches allows it to be easily stored. Overall I think this is a great design that could be useful up in space.
