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.
It didn’t sound like a big deal, but somehow you just instilled in me an existential dread of having no teeth to enjoy solid foods when craving some.
