The New York Times reports that the ingredient triclosan, which the FDA banned from antibacterial soaps recently, can still be legally used in some toothpastes. According to FDA spokesperson Andrea Fischer, the ingredient is “demonstrated to be effective at reducing plaque and gingivitis.” Fischer adds, “Based on scientific evidence, the balance of benefit and risk is favorable for these products.” The article noted that a 2013 Cochrane review “concluded that toothpastes with triclosan and fluoride outperformed those with only fluoride.”
The ADA reported previously that a study in the May 2016 issue of mSphere was “designed to examine whether use of consumer products” containing triclosan could “alter gut microbiome composition, endocrine function, and markers for obesity, diabetes, and inflammation.” The ADA says the study is “strongly suggestive” of triclosan’s “safety for use by humans.”
