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.
I’ve heard about something like this back in 90s for the first time. I guess we won’t see anything ever. Big tooth won’t allow it 😂
