dual tooth brush

The dual-sided toothbrush is a way to clean teeth quickly and more efficiently. The design makes it possible to clean all surfaces of the teeth at once. Aside from speeding up the toothbrushing process, the dual-sided toothbrush cleans teeth better. Tooth-decay happens faster in space, so astronauts cannot afford to miss a spot. With this toothbrush, astronauts can cover all sides of their teeth and their gums with one stroke, so astronauts will never miss a spot again. Lastly, the tubes coming out of the water packets of the ISS will inject through the bottom of the toothbrush into the nylon bristles. The water will stick to the friction of the bristles, so there will be no hassle. The rest of the toothbrush will be made out of PLA.
