i'm going to second the 'Deep Nutrition' as an accessible and simple way to address traditional foods and prioritize them for health.
My father was raised on a traditional foods diet (1st generation american) and though he had some baby teeth that never grew in, never saw a dentist, never had a cavity, and has very nice tooth and head formation. My mother is the daughter of a Dr who was formula fed, and ate standard food, and her siblings and her had a diverse history of orthodontic issues. My teeth weren't bad, but I had an overbite from sucking my thumb, and only one sibling in my family did not get braces, and extensive work and tooth-pulling were necessary for a couple. We also have bad eyesight and auto-immune issues. all of my grandparents had great teeth until later in life.
i started a raw foods diet before getting pregnant with my son (not vegan, mind, w/ raw egg yolks, minimally cooked red meat, and fish), and got into raw milk and the whole WAPF movement when my son was weaning. he has remarkably good spacing in his baby teeth, and has only one adult tooth coming in, but we're watching to see what will happen in the mouths of our children. I've improved my diet with each pregnancy, so hope that we can shift things. Dr. Price did find that parents could fix in one generation the teeth of children, as they could also get totally messed up in one generation. We do not consume candy, processed foods (chips and ketchup from whole foods being the one exception as a once a week treat), and especially focus on having loads of good fats and carefully treated grains along with grass-fed/pastured meat every single day. At this point, even though most siblings in both my husband and my family needed glasses either before or around 2nd grade, we have had no signs of anyone struggling with that, and our kids teeth are all straight, white and totally clean with minimal care. our pedi has commented on the health and size of all the mouths in our family.
so, will keep you posted and would love to see more about people's experience treating teeth naturally!
