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.
But you do replace your brake pads before the wear out completely instead of just letting them grind your rotors, right?
Most dentist visits are like oil changes and vehicle checks to make sure things aren’t going to fail catastrophically.
You would be surprised how many people already don’t maintain their teeth and they aren’t replaceable yet for non ferrets.
