FDA looks into dental device after KHN-CBS News investigation of patient harm

In the wake of a joint investigation by KHN and CBS News into a dental appliance that multiple lawsuits allege caused grievous harm to patients, the FDA has begun looking into the product, the Anterior Growth Guidance Appliance, or AGGA, according to a former agency official.

Additionally, KHN and CBS News have learned that the Las Vegas Institute, a training company that previously taught dentists to use the AGGA, now trains dentists to use another device it has described as "almost exactly the same appliance." That one is called the Anterior Remodeling Appliance, or ARA.

The FDA's interest in the AGGA was revealed by Cara Tenenbaum, a former senior policy adviser in the agency's device center who has said the FDA should investigate the product, which has been fitted on more than 10,000 dental patients, according to court records.
