Rami Nagel has compiled large amounts of info on natural dental health. I would contact him. I'm sure that avoiding nuts and there oils, taking fclo, and using orageno oil helps teath heal and be strong.
Your jaw can get bigger and make room for more teath. They sell equipment for that, I understand some products are better than others, but I'm confused past that.
2 years ago I saw an expensive, nice, natural dentist because I snored. He did bunches of tests, that cost so much I had nothing left for the appliance.
I did learn that I rested my tounge in my jaw wich misshaped my whole mouth, led to slack in my soft pallet and caused snoring. They said the appiance was required to correct the problem. I decided to try to intentionally place my tounge in the roof of my mouth, hoping it would help. Dentist said it wouldn't and that I couldn't controll what I did while sleeping.
I didn't accept that. I had nothing to loose and I reasoned that my tounge placement was a bad habit. I could break it consciously and unconscious would take care of itself. It didn't happen over night but, my jaw is much wider. My tounge fits nicely now, where it was cramped before. At first I had to suction my tounge to the roof of my mouth and it was in the way of my teeth so I kept them open, just a bit.
It reminded me of what I learned about how infant suckeling contributed to health jaw growth. That encouraged me to endure a mild head/tmj ache lasted months. It did become habit. My tounge fits nicely in my mouth now. The jaw widens too and I have more room between all of my teeth. (Obvious with flossing).
Eating carbs is ruining my teeth. I hope to kick them soon. Are you still low carb due to fructose sensitivity? Now that your off pasta and getting plenty of raw fat and protien your teeth could heal/grow remarkably.
