Goodbye root canals? Researchers use lasers to regrow parts of teeth | Fox News: In a new study published in the journal Science Translational Medicine, lead researcher Praveen Arany and colleagues detailed how they used focused laser light therapy on rats to stimulate the growth of lost dentin, the calcified tissue that comprises teeth. They noted that if the therapy proves effective in humans, it could potentially eliminate the need for crowns, fillings and other complex dental operations in the future.
