The American Dental Association is an American professional association established in 1859 which has more than 159,000 members. The ADA is the world's largest and oldest national dental association. The organization lobbies on behalf of the American dental profession and provides dental accreditation.
The ADA publishes the Journal of the American Dental Association and JADA Foundational Science.
As part of its lobbying efforts, the ADA has sought to restrict non-dentists from providing basic dental care. The organization has played an important role in blocking the inclusion of dental coverage in Medicare. From Wikipedia
