Antimicrobial peptides as mouthwash were first invented in 2011 at UCLA according to this article. There was a brief burst of news/media attention around them in 2015 and then nothing. What happened to them? Are these mouthwashes available anywhere (including outside the U.S. or in experiments/clinical trials) and where can I get them?
Several searches for where to buy them turned up nothing.
Extra credit question: could this approach be used as a substitute for antibiotics in certain applications or deployed against bacteria that are dangerously resistant to regular antibiotics?
