Cavemen Didn't Brush Their Teeth, So Why Should I?

 

 I can simply tell you the most important reason: A Human diet bears almost no resemblance to the diet we evolved with AT ALL.

Also, remember, humans have not been evolving or subject to Natural Selection for millennia. 10,000 years ago, a group of humans could lure a herd of giant ruminants near a cliff, startle them into bolting over the cliff, and slaughter the animals at their leisure at the bottom. THAT’S not natural at all.

Yet the thing that has affected human dental disease the most is the rapid and sophisticated advancement in food growing, gathering and processing. Take the humble pie (see how I did that?). A pie is a tremendously unnatural foodstuff. You have the crust - a sweet, melt in your mouth mixture of grass seed powder (flour), sugar (an amazingly unnatural concentrated product), butter or oil (ditto), and the unfertilized eggs of a domesticated bird. In this sweet, sticky, pasty, flaky cooked (!) container, you place fruit (collected in a group, stored, and allowed to soften and concentrate their sugars), mixed with MORE powdered grass seed (flour) and MORE sugar. The human body was simply never evolved to handle this immensely caloric, starchy, sticky mess.

Guess who’s waiting to feast on the pasty mass that adheres to your teeth? Billions and billions of bacteria (called Sptreptococcus mutans) whose sole purpose in life is to digest the starch into sugar for their own use, and then produce tooth decaying acids inside this rotting, decaying mess of food paste, bacteria, and water (saliva) that is stuck to your teeth.
