Stem-Cell Research Makes Progress in Quest to Avoid the Dreaded Drill

WallStreetJournal-logoCould the days of the root canal, for decades the symbol of the most excruciating kind of minor surgery, finally be numbered?

Scientists have made advances in treating tooth decay that they hope will let them restore tooth tissue—and avoid the painful dental procedure. Several recent studies have demonstrated in animals that procedures involving tooth stem cells appear to regrow the critical, living tooth tissue known as pulp.

Treatments that prompt the body to regrow its own tissues and organs are known broadly as regenerative medicine. There is significant interest in figuring out how to implement this knowledge to help the many people with cavities and disease that lead to tooth loss.

In the U.S., half of kids have had at least one cavity by the time they are 15 years old and a quarter of adults over the age of 65 have lost all of their teeth, according to the Centers for Disease Control and Prevention. An estimated $108 billion was spent on dental services in 2010, including elective and out-of-pocket care, according to the CDC.
