Wait a minute, do you mean you are hoping for the tooth to not just remineralize decay, but regrow larger? I'm afraid that's highly doubtful and even Ramiel doesn't make that claim, though if by some miracle it happens, do let us know.
Here are some raw Paleo foods that Ramiel recommends:
Organic Liver
Grassfed Meats
Vegetables
Bone marrow
Blue Ice raw fermented cod liver oil (centrifuged--some heat possible)
Vegetable Juice (maybe not technically raw Paleo, as Stone Agers probably didn't juice veggies, but close)
His recommended foods that are not raw Paleo:
Bone broth
High vitamin butter oil (centrifuged--some heat possible)
Organic Butter (churned--some heat possible)
Raw Milk
Cheese (probably raw)
Cream (probably raw)
His other recommendations:
Blotting-style tooth brush (I didn't notice any difference with this)
Tooth soap (I didn't care for this--it is literally soap)
