The Science Behind Dental Stem Cell Banking

Thousands of clinical studies. Decades of research. Here's what the science actually shows.

What Makes Dental Stem Cells Valuable

The pulp inside your teeth contains mesenchymal stem cells (MSCs) — the same cell type used in most regenerative medicine research today. Unlike controversial embryonic stem cells, MSCs are adult stem cells with a long clinical track record and no ethical concerns.

Two specific types come from teeth:

  • DPSCs (Dental Pulp Stem Cells) — found in wisdom teeth and permanent teeth

  • SHEDs (Stem cells from Human Exfoliated Deciduous teeth) — found in naturally lost baby teeth

Both have demonstrated higher growth potential than bone marrow-derived stem cells, and can be collected non-invasively from teeth your child would lose anyway.

What the Research Shows

Neurological conditions

Dental pulp stem cells have shown therapeutic potential in pre-clinical and early clinical studies for spinal cord injuries, Parkinson's disease, Alzheimer's disease, and cerebral ischemia.

Diabetes

Mesenchymal stem cell therapy is being studied as a treatment for Type 1 diabetes, with multiple ongoing clinical trials investigating whether MSCs can preserve insulin-producing cells in newly diagnosed patients.

Bone and dental tissue regeneration

DPSCs have demonstrated the ability to regenerate dentin, pulp, and bone tissue in laboratory and pre-clinical studies — making them especially promising for facial reconstruction and jawbone regeneration.

Cartilage and joint repair

MSCs from dental pulp can differentiate into cartilage-producing cells, opening potential applications for arthritis, cartilage damage, and orthopedic regeneration.

Heart disease

Preliminary research suggests MSC therapy may reduce scar tissue and improve heart function following heart attacks, though human trials remain in early phases.

Currently Approved vs. Emerging Applications

The U.S. National Institutes of Health currently lists thousands of active and completed clinical trials involving mesenchymal stem cells. You can browse them yourself at clinicaltrials.gov.

Why Dental Stem Cells Specifically

Three reasons dental pulp is a uniquely valuable source:

Non-invasive collection. Other stem cell sources require invasive procedures — bone marrow biopsies, surgical extractions, or collection at birth. Dental stem cells come from teeth you'd otherwise discard: lost baby teeth, removed wisdom teeth, or teeth pulled for orthodontic reasons.

Young, potent cells. Stem cells age with the body. Banking cells from a child's baby teeth captures them at their most regeneratively powerful — long before the wear and damage of adult life affects their function.

A second chance after birth. Cord blood banking is a one-time opportunity at birth. Dental stem cell banking gives families who missed that window — or who have additional children — another opportunity to preserve a child's stem cells.
