I can’t get Nutri Dents anywhere here, but a couple of them came with one of my puppies two and a half years back, so they can’t be that new. I used to use Greenies and I found that they had questionable ingredients and unless I got a size that was for a much bigger dog, they weren’t enough of a chewing challenge to clean my dogs teeth. The Nutri Dents also had ingredients in them that I wouldn’t want to feed all the time, but they lasted longer. I can’t really say they cleaned the teeth either though.
