An innovative gel that forms a layer over teeth and then recruits calcium and phosphate ions from saliva to build new enamel has the potential to change dental treatment. To date, we don't have any way to regenerate the tough outer layer of enamel on our teeth as it erodes with age.
Absolutely, which was my point. That the tooth thing wasn’t “only two years ago” it’s actually been in the research and development process for probably over 15 years at this point, with a long way to go.
