No.. there are 3 classifications. One is that you are good, 2 is that you are good, but need work and 3 is that you are not good. I dont know what you need for the 3rd, but I had 2. I have a tooth with a rootcanal done, and it wasnt capped. Cracked a bit. During the physical they yelled at me, but approved me. The just said I needed to get it fixed... but I could wait until I get in. Also that I would need my wisdoms removed, but once again... wait until the Marines will pay. So unless you have like 8 teeth missing, and there could be a future infection, you shouldnt fail. (But cavities will kill you, so get them fixed!)
