Regenerating Teeth: Scientists Aim to Grow a Living Tooth

Researchers are pursuing regenerative dentistry to regrow teeth using stem cells and tissue engineering, aiming to replace fillings and implants with living tooth tissue; early work has yielded enamel- and dentine-forming cells that can create tooth-like organs and even lab-grown teeth in animal models, but practical human application is years away and will require safer, more advanced environments before trials.
