Prosthodontics is one of nine ADA specialties. After completing four years of dental school a student will receive their DMD or DDS degree (there is no difference between the two) and upon completion and passing of necessary licensing exams are able to begin practicing dentistry. Most schools have any where from 50 to 100 students in a graduating class and most of these students will go on to apply to dental residencies (specialty or general) rather than begin practicing.
