I’ve been using K2 for a little over a year, teeth and other benefits as outlined in the WAPF linked article.
Two weeks ago I went to have a tooth prepped for a crown (old fillings in a configuration that risked having the tooth fracture down to the root- thus causing total loss of the tooth- I’ll take the crown… plus I’m more valuable now with gold in me 
)
The dentist froze me then started grinding away the enamel, despite being frozen, it hurt, she had to push hard on the drill. After about 10 minutes of this she mentioned to her assistant that the burr must be worn out and dull, it wasn’t cutting very well. So she chucked the old one in the garbage, put a new one (out of the brand new box- not just a clean one) and kept on drilling. The new one didn’t cut any better than the old one. A minute into this she specifically asked if it had been a new burr, the response. “yes, right out of the box”.
So when we were waiting for the temporary crown to get prepped I had the chance to ask about whether she thought my enamel was hard, I can’t remember the exact words but they were along the lines of “Some of the hardest I’ve ever seen”. So hard that we had planned to replace other old fillings but the consensus was that the enamel was so hard and tough that the tooth would likely be just fine as it was, the chance of any problems are so small they are not worth worrying about.
So that was my opening to talk about K2 and what (little) is known about its effect on teeth and dental health. She was interested enough that when I offered to supply some information she was interested. We’ll see what happens down the road. I figure anything that gets good helpful information out there helps.
