Amen. My family dentist growing up filled every tooth in my mouth with mercury fillings. When there were no more teeth to fill he convince my parents that the teeth with fillings now needed more fillings.
Dentists since then have asked me if I was aware that some of my teeth had 3 fillings! Grrr!!
You're right that natural/alternative dental care is for some reason off the radar of most alternative health types. Which is strange since filling your mouth with mercury and canals is so outrageously bad for your health.
At least we can pass on the benefits to our kids. My kids have had the fewest possible vaccines, no circumcision, no fillings, no prescription medicine and except for tennis and football no TV! (Can't get them to OP yet).
It sounds like you're enjoying the benefits of being proactive with your health right along with your children - nicely done!
