Firms 'mislead' parents with claims of tooth stem cells used to treat autism
The Guardian
|August 21, 2025
Companies are making thousands of pounds by misleading parents with claims that collecting stem cells from their children's teeth can be a treatment for diabetes and autism, an investigation has found.
Tooth stem cell banking, also known as dental pulp cell banking, involves parents collecting and sending lost milk teeth to a laboratory where stem cells are harvested from the dental pulp. Firms that advertise tooth banking claim these stem cells can be used in treatments for conditions such as diabetes and autism.
The investigation, by Emma Wilkinson and published in the BMJ, found that three companies in the UK offer tooth stem cell banking - BioEden, Future Health Biobank and Stem Protect. The service costs about £1,900, with a £95 annual storage fee.
