After graduating from dental school, a dentist is awarded either a DDS or a DMD degree:
There is no difference between the two degrees. Both dentists have the same education.
They have also completed the same curriculum requirements set by the American Dental
Association's Commission on Dental Accreditation. The difference is wording that is
determined by the universities. Some institutions award a DMD degree. Others award
a DDS degree. Generally, 3 or more years of undergraduate college education plus 4
years of dental school is required to graduate and become a general dentist. State
licensing boards accept either degree. And both degrees allow licensed professionals
to practice the same scope of general dentistry.
Additional postgraduate training is required to become a dental specialist. A person
often consults with a dental specialist after referral from their general dentist.
