Losing your teeth is one of many folks' greatest fears and is fodder for many disturbing nightmares. Replacing lost teeth is yet another dreadful experience, not just because visiting the dentist can be uncomfortable, but also due to the high cost and often invasive nature of such oral procedures.
But someday a drug could change that, making it easy to regrow one's teeth just like a lost fingernail or your hair. New research from Kyoto University Hospital in Japan has already regrown teeth in the mouths of mice and ferrets, prompting experts to prepare for human testing, according to New Atlas.
