According to a first-of-its-kind estimate by The Dallas Morning News, roughly 1,000 U.S. dental patients have died since 2010.

Even those who are disciplined can find it easy to keep working with little or no oversight.

Dallas Morning News Staff Writer Brooks Egerton joins Insight to talk about his investigation and his published findings.
