Earlier this year, I had eaten lots of Oranges and other fruit without raw fats throughout the day, which caused my body to Detox the Heavy Metals I had built up over my whole Life through my teeth.
But ever since being on the Primal Diet and eating raw Butter with my fruit, limiting my fruit to only once daily and rinsing my mouth with raw milk after eating the fruit, my teeth have minimally whitened and have become smoother on the surface.
I'd say raw Butter is the food you should be eating in big amounts, if you want to re-mineralize or even reverse your decaying teeth.
Keep in mind I have only been on this strict Primal Diet for 1 1/2 months.
If you want to reverse absolutely anything you should consider hopping on the Primal Diet.
