Anecdotal of course but because of my long-covid I have been taking a ton of Vitamin K2 over the past few years.
And all my teeth aches are gone, one less problem to worry about.
This matches reports by others that K2 seems to pull calcium out of your saliva and into your gums/teeth where it should be and makes them stronger. Maybe. It does seem to keep teeth more "squeaky clean".
