Coming Soon: Caffeine-Infused ...Toothbrush? Colgate applies for chemical-releasing brush patent By Arden Dier, Newser Staff Posted May 17, 2013 3:32 PM CDT 24 comments Comments (Shutterstock) (Newser) – Who needs a morning coffee when your toothbrush releases a dose of caffeine? Colgate has applied for a patent on a brush that could do just that. The application describes "a toothbrush that releases a chemical into the mouth during use," but it won't stop at caffeine, reports Yahoo. The brush could also deliver drugs like aspirin, herbal remedies, or just a certain flavor dispensed from a patch attached to the head of the brush, with each patch lasting three months, according to the Daily Mail. Possible flavors include berry, green apple, and everyone's favorite in the morning—chili pepper.
