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.
those would be abnormal though, the genetics behind the tumor is probably not like a normal chromosomes(partial deletions, extra copies,etc). odontomas, and teratomas produces it but they are abnormal teeth.
