Yes, recent research backs this. A Jan 2025 study in Stem Cell Research & Therapy (Ibarretxe et al.) isolated dental pulp stem cells from wisdom teeth (third molars) and differentiated them into neuron-like cells that fire real electrical signals/action potentials—key for brain repair potential.
These mesenchymal stem cells also show osteogenic differentiation for bone/joint repair and paracrine effects aiding heart function in mouse models of failure.
Could lead to autologous regenerative therapies: banking extracted teeth for personalized treatments of neurodegeneration, fractures, or cardiac damage. Mostly lab/preclinical so far, with early trials emerging.
