There's a raft of claims recently that baby (or milk) teeth are are a rich source of stem cells and could be used in the future to help cure diseases to or regrow failed and damaged organs. These claims are encouraging parents to save their children's baby teeth.
For example, this 2013 article by a dentist in the Daily Mail:
What uses are there for the stem cells from such teeth?
They currently have no practical use, but that does not mean they don’t have the potential for clinical use in the future. Scientists have grown rodent teeth from deciduous-tooth stem cells already, so we know they have the potential to regenerate teeth. They can become bone cells, so could repair bone defects. But we are still learning about their biology and potential.
That said, the vast majority of first page hits on Google are all from companies offering to bank those teeth, suggesting that these claims may be driven by those with a profit motive rather than by very much scientific research:
WHAT'S TRUE: Research shows that stem cells can be harvested from baby teeth and have potential dental and medical uses in repairing and regenerating tissues, and commercial facilities exist for the preservation and storage of dental stem cells for future use, at a price.
WHAT'S UNDETERMINED: Whether, to what degree, or when such potential uses for dental stem cells will actually come to pass.
Is there any definitive information supporting or refuting the claim?
As a followup, do companies offering services for storing baby teeth actually do anything more useful than a plastic box in the family keepsakes drawer?
