People are too profitable for the system to be motivated to figure out actual causes behind common problems. Your quip reminds me of a comment from 2 weeks ago, where someone shared how vitamin K supplementation helped reduce buildup on their teeth: https://news.ycombinator.com/item?id=20902899 https://news.ycombinator.com/item?id=20902899 I understand that people usually get adequate Vitamin K2 from their intestinal bacteria. Perhaps the buildup on your teeth is due to your microbiome. I brush with salt and baking soda, but still have some plaque on my occasional visits to the dentist. I’ll have to think about this some more.
