The American Dental Association is the world's largest and oldest not-for-profit national dental association, serving the public and representing 159,000 member dentists worldwide. As the premier source of oral health information, the ADA supports practicing dentists, dental hygienists, assistants, and practice managers, as well as students, with print and digital professional resources and patient education that promote health, safety, and education as well as the management and maintenance of dental practices. We are also strong advocates for public health ? fighting oral cancer and combating the opioids crisis ? and we're teaming up with industry partners to help you stay healthy from the dental chair to daily care at home. We will continue working toward our vision ? working side by side with our member dentists ? to achieve optimal health for all.
