Most ancient cultures DID NOT die of degenerative disease.

If you read "Nutrition and Physical Degeneration" Weston A Price, you will be blown away by the teeth of those who do not brush. Price was a dentist and looked very closely at teeth. He also did many studies on ancient bones, almost all of which had near perfect teeth.

I am not saying not to brush however. Just don't brush with things that are toxic to the body.

Sanitation IS a big thing that changed history. But you can do it the toxic or non toxic way.

Kind of a no brainer to me. But we all think differently.

Do I worry a minuit about it? No
If I forgot my tooth paste I would use a friends.

Am I going to buy poisons to put in my body? No
