80beats– This is a really exciting study. As someone who spends an awful lot of money on dental bills despite doing everything that those accusing hygienists tell you to do, I’ve been waiting for a break on this front. It’s pretty clear that some people (myself included) simply have bad teeth. It’s not that there’s anything different about the enamel– it’s got to be related to the chemistry of the saliva or the populations of bacteria in the mouth. Enter this study. If you’re anything like me, I’d suggest keeping a close eye on this research.
