JOURNAL OF NATURAL SCIENCE, BIOLOGY, AND MEDICINE: Scientists have discovered that wisdom teeth — often removed and discarded in adolescence or young adulthood — contain a rich supply of mesenchymal stem cells capable of transforming into bone, muscle, nerve, and other vital tissues.

Your wisdom teeth could save your life.

Your wisdom teeth could save your life. They contain stem cells that could repair your heart, bone, and even brain tissue. What was once considered medical waste may soon be a powerful tool in regenerative medicine. Scientists have discovered that wisdom teeth — often removed and discarded in adolescence or young adulthood — contain a rich supply of mesenchymal stem cells capable of transforming into bone, muscle, nerve, and other vital tissues. Dental stem cells have shown promise in preclinical studies for conditions ranging from arthritis and diabetes to cognitive disorders like Alzheimer’s and Parkinson’s disease. And unlike stem cell collection from bone marrow or blood, harvesting dental pulp during wisdom tooth removal involves no additional procedures or discomfort.

Alzheimer’s may be linked to gum bacteria, new research shows. Scientists have repeatedly found Porphyromonas gingivalis—the chief bacterium that causes periodontitis—inside the brains of people who died with Alzheimer’s. When researchers deliberately infected mice with this oral bacterium, the animals rapidly developed key Alzheimer’s pathology, including the buildup of amyloid-beta plaques. Perhaps most alarming, the bacteria’s toxic enzymes have been detected in the brains of people showing early Alzheimer’s changes years before memory loss or other symptoms appear, suggesting the infection may quietly initiate damage long in advance. These discoveries have sparked serious interest in new treatment approaches. An experimental drug called COR388 (from the company Cortexyme) has already succeeded in lowering both bacterial load and amyloid-beta levels in preclinical models. Although large human trials are still needed, the evidence is mounting that at least some cases of Alzheimer’s may have an infectious trigger rather than being purely degenerative. [Dominy, S.
