The researchers used extracted human molars as an ex vivo model, first etching their enamel or dentine surfaces with acid to mimic different stages of tooth erosion. They then applied a single coating of the biomimetic elastin-like recombinamer (ELR) gel and let it dry. Finally, the teeth were immersed in carefully controlled mineralization baths that replicated the ionic environment of saliva.
Keep in mind this hasn’t been shown to actually help teeth in someone’s mouth.
Just from that, it seems like its a patch job, not capable of regrowing from zero.
To be fair, the research is on regenerating, not regrowing. I wouldn’t expect regrowing lost teeth to be possible any time soon, unless some kind of bio 3D-printing method became available.
“Dental enamel has a unique structure, which gives enamel its remarkable properties that protect our teeth throughout life against physical, chemical, and thermal insults,” said lead author Dr. Abshar Hasan
This man doesn’t just disapprove of people mistreating their teeth, he is personally insulted by it. A true dentist.
I could never ever work in that field, it gives me the ick. So I appreciate people who can.
Also enamel is the hardest substance in your body; AFAIK chemically it is indeed interesting and hard (ha) to emulate with other bio-safe materials.
