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.

Colgate-Palmolive (Colgate) has sent the first-ever private sector oral care experiment to the International Space Station (ISS), under the sponsorship of the ISS U.S. National Laboratory (National Lab).

The 3,300-kilogram shipment — which also includes fresh lemons, onions, avocados and cherry tomatoes for the station's seven astronauts — should arrive on Saturday.

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.

Rocket due to reach the International Space Station this weekend is loaded with 7,300lb of fresh food and supplies for an orbiting lab.

The University of Nevada, Las Vegas is teaming up once again with NASA to conduct research, this time to determine if oral bacteria grows the same way in weightlessness as it does in the mouths of humans on Earth.

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

Researchers from UNLV'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.
