Rebuilding Teeth with Laser Therapy
the MPR take:
Non-ionizing, low-power laser (LPL) treatment may be coming to a dentist office near you in the future. In a study published in Science Translational Medicine, researchers at Harvard were successfully able to activate stem cells to regenerate dental tissue using this noninvasive laser therapy in mice and rats. When activated by the laser, the regulatory cell protein transforming growth factor beta-1 (TGF-β1) was able to differentiate human dental stem cells in vitro. Future research will expand on investigating this potential treatment with humans, but lasers could one day become a dental mainstay.

Researchers at Harvard have discovered a way to use noninvasive laser therapy to prompt stem cells to regenerate dental tissue, according to a new study published in Science Translational Medicine.
