LAS VEGAS (KTNV) — UNLV researchers are looking into how effective toothpaste is in space.
The university teamed up with NASA and Colgate. They're launching a rocket Thursday carrying oral bacteria and saliva gathered from UNLV dental patients and 25 test kits.
Researchers plan to test the germ's growth and treatment with Colgate toothpaste, mouthwash and other products.
