You read the title, if everyone followed this advice dentists would go jobless. What I am going to tell you will be the best dietary advice you will ever have. If you have a toothache then you should copypaste this and save as a text file.

This is derived from the weston a price diet plan which is very long but boils down to this in the most practical manner.

Drink raw milk and avoid phytic acid

How to store raw milk:
You would want to store in the freezer after buying a big bulk of 6 raw milk bottles. However upon taking it out of the freezer the probiotic bacteria would have died, so to fix this you would have a 1/8 filled raw milk bottle that is left outside to ferment and produce the bacteria so that when you take it out of the fridge you would “reinfect” it with probiotic bacteria.

If it “rots” it is actually safe to consume. The solids it produces is called kefir. It tastes like philadelphia cheese.
