Wow, this could end up being a major break through in dental science. The possibility that losing adult teeth may not mean dentures! This would mean a new life of having teeth for people like my wife and my oldest son who are genetically pre-disposed to having bad teeth. My son had two BABY teeth rot from the inside out and had to be removed. This isn't his fault nor is there anything he could have done to prevent it. This will most likely happen a couple times in his adult life as well, according to the dentist. But this new technique would allow him to regrow his adult teeth if it progresses enough.
