My guess is that the "process" will be to add it to toothpaste. Seems like the perfect vehicle to me...the mother of pearl component, plus carriers for calcium and phosphate (maybe just calcium phosphate itself). You don't get a huge exposure time for any one brushing, but over a lifetime.........
After all, today you have things like "Prevident" to HARDEN the surfaces of teeth...why not a toothpaste that can actually rebuild them.
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?
