In 2013, extensive research was conducted by Songtao Shi, DDS, MS, PhD, from The National Institute of Dental and Craniofacial Research on human baby teeth. What he found was truly amazing.
Dr. Shi discovered that baby teeth contain at least one or two stem cells. While this might not be big news to some, stem cells from childhood might come in handy later on in life. In order to properly preserve a baby tooth, an adequate supply of blood is needed before it is frozen, so parents can’t just tuck the baby teeth away and access those stem cells later.
Stem cell banking is an emerging service that can accommodate this kind of bio-preservation. These services store the baby teeth in liquid nitrogen in a cryopreservation vault for safe-keeping. This makes it possible for the stem cells to remain intact for years, and can be extracted later if the child needs the stem cells to be repurposed as a treatment.
