Toothpaste ads promise smiles that are out of this world. Now UNLV is assisting Colgate-Palmolive to put that claim to the test.

As the saying goes, "the sky is the limit". This is true for scientists conducting the first oral health experiment in space to evaluate the growth and response of oral bacteria to the agents being treated in zero gravity.

In order to better understand the growth and metabolism of oral biofilms, scientists are conducting a new oral care experiment in space.

As the saying goes, the sky is the limit. This is true for the scientists conducting the first oral health experiment in space to investigate the growth and response of oral bacteria to treatment agents in zero gravity. The project, which is being sponsored by the International Space Station U.S. National Laboratory and conducted in collaboration with NASA and Colgate-Palmolive, will last two months and is partly aimed at improving oral health treatment on the ground.

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.
