Hi! I am currently a D2 in dental school on the HPSP scholarship. I would like to specialize in oral surgery, and I know I have several options. However, if I chose to serve my four years as a general dentist in the dental corps and then decided to pursue oral surgery residency as a civilian, how competitive would I be? Would I need new CBSE scores or do they not expire after a couple of years? Or should I do my residency right after dental school and then owe back my years in dental school and residency? I would greatly appreciate any comments! Thank you.
