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 bet the catch here is it could accidentally grow anywhere in the body as long as it mimics what our mouth has (saliva). Imagine growing enamel in our tongues or throat.
