What are stem cells, and how can they be used by dentists?
Stem cells are universal cells that can morph into other types of tissue. One of the easiest sources of stem cells turn out to be in the pulp tissue of teeth. Exfoliated deciduous teeth are the most natural and noninvasive sources to harvest stem cells. The known but limited regenerative capacity of the pulp has been attributed to the function of the dental stem cells. Stem cell research in mice has proven successful in regenerating pulp tissue and dentin. This procedure may one day replace dental fillings.
The ultimate goal in stem cell research is to one day replace the traditional dental implant and allow patients to regrow a lost tooth.
