Wisdom tooth extraction is a rite of passage for millions each year. Threatening, inconvenient, and painful, the third molars are often removed and discarded. But new research published in Stem Cell Research & Therapy shows these teeth contain valuable stem cells. These cells may help treat brain, heart, and joint diseases.⁠ ⁠ Each wisdom tooth holds dental pulp, a soft core filled with stem cells. In lab settings, researchers can turn these cells into nerve, bone, or heart tissue. Remarkably, lab-grown neuron-like cells from wisdom teeth can fire electrical signals. This means they may one day replace damaged brain cells.⁠ ⁠ Roughly 10 million wisdom teeth are removed in the U.S. each year. Most are thrown away, but they may be a hidden medical resource. New findings suggest these cells could be key to future therapies.⁠ ⁠ ⁠ ⁠ #wisdomteeth #teeth #dental #medicine #biology #science
