National Dental Association
The National Dental Association (NDA) is a professional association of minority dentists based in Washington, DC and operating in the United States, Canada and Latin America. Formed in 1913, it is the largest such association in the world. Among the aims of the NDA is extending dental treatment and education to impoverished, disabled or minority populations, as well as those who mayn't be able to seek proper care due to age. It also works to maintain professional standards in dentistry and to encourage dental careers among minority populations.
