As the famous TV ad said, four out of five dentists recommend Colgate toothpaste … on Earth. But, what about in space?

SpaceX launched thousands of tiny sea creatures to the International Space Station on Thursday, along with a plaque-fighting toothpaste experiment and powerful solar panels.

Researchers from 51³Ô¹ÏºÚÁÏ's Howard R. Hughes College of Engineering and School of Dental Medicine partnered with NASA and Colgate-Palmolive to study the growth of oral bacteria in space and see if Colgate oral care products are effective in a microgravity environment.

Colgate-Palmolive will send an oral care experiment to the International Space Station (ISS) aboard SpaceX’s 22nd commercial resupply services mission scheduled to launch from the Kennedy Space Center in Florida.
