UW Dentistry researchers testing oral bacteria transplants to cure bad breath (opens in new tab)

To rebalance the oral microbiome and cure chronic halitosis, researchers at the University of Washington are embarking on a first-of-its-kind experiment. These clinical trials transplant bacteria and other minuscule critters from healthy donors into patients with halitosis. If successful, the healthy microbiota will crowd out the bad and patients’ bad breath will improve.
