It won’t be available anytime soon, of course, but it’s great progress:

Regenerative dental fillings that allow teeth to heal themselves have been developed by researchers, potentially eliminating the need for root canals.

The treatment, developed by scientists from the University of Nottingham and Harvard University, earned a prize from the Royal Society of Chemistry after judges described it as a “new paradigm for dental treatments.”

The tooth filling works by stimulating stem cells to encourage the growth of dentin—the bony material that makes up the majority of the tooth—allowing patients to effectively regrow teeth that are damaged through dental disease.
