The DDS (Doctor of Dental Surgery) and DMD (Doctor of Medicine in Dentistry or Doctor of Dental Medicine) mean the same thing—your dentist graduated from an accredited dental school. Dentists who have a DMD or DDS have the same education.
All dentists have one of two degrees that they are associated with. They will either DDS or DMD. According to the American Dental Association (ADA), there is no difference between the two degrees. Dentists with either degree have graduated from an accredited dental school and are highly trained professionals in their fields. They have the same type of training and both fulfill the curriculum requirement as set by the ADA. It is up to individual dental schools to decide whether to offer a DDS or DMD degree.
