Trial aim to save teeth

MINCED tooth pulp is being tested as a way to regenerate decayed teeth and reduce the number of extractions that are necessary.

The pulp – the soft inner part of the teeth containing blood vessels and nerves – is rich in stem cells, which have the potential to grow into many types of cell.

The theory is that these stems cells will develop and regenerate the various parts of the tooth that have been destroyed by decay.

If early tests prove successful, this method could prove an alternative to painful root canal fillings and reduce the need for extractions.

It is hoped that the new procedure, on trial at the University of California, will kick-start the growth of new pulp and dentine, strengthening the tooth and its roots.

“Researchers are hoping the patient’s own cells will regrow the ‘nerve’ inside the tooth and also lead to a new blood supply. This regeneration, if successful, will help keep the tooth,” a spokesman said.
