Harvard was the first to offer the DMD. Some people picked it up. The ADA tries to get everyone to use DDS, but people won't change because of "tradition". There is no difference between the degrees. I personally prefer DDS because thats what I'm gonna have.🙂
Anyways, there is no difference. But just preference now a days. I hear people in the Middle of the US want DMD cuz patients go to DMD's more. Just something I heard.
