“Arginine, a common amino acid found naturally in foods, breaks down dental plaque, which could help millions of people avoid cavities and gum disease, researchers at the University of Michigan and Newcastle University have discovered.
Alexander Rickard, assistant professor of epidemiology at the U-M School of Public Health, and colleagues, discovered that in the lab L-arginine—found in red meat, poultry, fish and dairy products, and is already used in dental products for tooth sensitivity—stopped the formation of dental plaque.
“This is important as bacteria like to aggregate on surfaces to form biofilms. Dental plaque is a biofilm,” Rickard said. “Biofilms account for more than 50 percent of all hospital infections. Dental plaque biofilms contribute to the billions of dollars of dental treatments and office visits every year in the United States.””
