I wonder about the nacre (mother of pearl) component. I was told how fragile nacre was (on cultured and natural pearls): never expose it to acid, it will damage the surface. Can you eat a salad with vinaigrette dressing and expect to keep teeth mended with this new process?

Which is another reason why including the components in toothpaste is a logical approach. You brush your teeth (hopefully) multiple times a day. You would not eat highly acidic foods nearly as often. So "repair time" should exceed "damage time" by a large factor.
