Tooth repair drug may replace fillings

A dentist at work (Public domain)Tooth fillings could be a thing of the past. A study has shown that our teeth’s natural ability to repair themselves can be boosted using a drug. Called Tideglusib, it has been specially developed as a treatment for Alzheimer’s, which is a form of dementia, a group of diseases of the brain that cause loss of the ability to think clearly. Scientists have discovered that Tideglusib also heightens the activity of stem cells in dental pulp, the soft centre of a tooth.

Stem cells are different from the rest of the cells in your body in that they are able to renew themselves: they can divide into many more cells that are exactly like the original ones. In this way, stem cells can repair or replace tissue in the human body. Stem cells are found in the brain, bone marrow, blood, blood vessels, skeletal muscles, skin, liver—and teeth. The cells remain in a non-dividing state, sometimes for years on end, until they are activated by the onset of disease or an injury to the tissue.
