Hope someone can commercialize a process to rebuild enamel. It would be a great advancement.
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.
