All about the AGD and your Doctors
AGD members challenge themselves to learn more so that they can provide their patients with the best quality care.
All dentists are required to take continuing education (CE) every year to keep their license up-to-date. When a dentist becomes an AGD member, though, they are required to take 75 hours of CE every three years just to belong to the organization. For a dentist, CE can include courses on a range of topics, from teeth whitening to implants.
Fellowship or Mastership
AGD members are so committed to quality patient care through continued education that many of them earn awards for their educational accomplishments.
The AGD offers Fellowship (FAGD) and Mastership (MAGD) awards to members who truly go above and beyond in their learning. To earn a Fellowship award, a dentist must complete at least 500 continuing dental education hours, pass a rigorous and comprehensive exam, and maintain AGD membership for three continuous years. To receive the Mastership award, a dentist must first receive his or her Fellowship award. Then, the dentist must earn an additional 600 approved CE hours within specific dental disciplines.
