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.
No offense, but unless you have some sort of condition like not growing enamel, what have you been doing for your teeth to be that bad at not even 50? Chewing on anvils and flossing with barbed wire?
Bruxism. Why, what’s wrong with you? Sheesh.
