I have been thinking about possibly doing a DDS/DMD/PhD program. However, since I want to go into oral surgery, do you think the extra 4 yrs for the PhD are worth the time? I already have about 2 years of research experience under my belt as an undergrad (and I think some of my research could go towards PhD work if I decide to do it), and my PI offered to have me as a grad student if I can get into the dental school here (at UMich). I'm kinda caught in between on this one, and would appreciate some feedback.
