It might be a little early to get excited about regenerating teeth, however. The tooth enamel was repaired in laboratory conditions with extracted teeth in a simulated mouth environment. The solution also only repaired small sections of enamel. Next steps for the team include animal testing, verifying toxicity is at safe levels and increasing the enamel repaired per treatment.
But even with all the work ahead, this technology could have some pretty wild implications for the field of dentistry. Think about it — dental drills could become a thing of the past.
