Some Toothpastes Work Better Than Others

BUFFALO, N.Y., April 14 (UPI) — Some toothpastes work better than others in curbing the some 800 to 1,000 different kinds of bacteria that live in the human mouth, U.S. researchers said.

Joseph J. Zambon of the University at Buffalo School of Dental Medicine, a dentist and one of the study’s authors, said that many of the bacteria form dental plaque, which causes cavities, gingivitis and gum disease.


The researchers tested one kind of toothpaste containing triclosan/copolymer and two fluoride toothpastes on different kinds of bacteria that mimic germs in the mouth grown in the laboratory as well as bacteria from human mouths.

The study, published in the journal General Dentistry, found the toothpaste with triclosan/copolymer outperformed the fluoride-only toothpastes in curbing the growth of bacteria.
