You mean before you deploy? Should've let uncle take care of that one. I'm assuming you aren't having a problem with it--or are you? Are you talking about a straight ahead tooth implant or a jaw or TM subsititute like Vitek?
If all you mean is you got a tooth on a post so you'd have a sunny sunshine smile for your DI or top kick, then just tell your medical so it gets in your jacket if you need to. No big production needed.
Before you ship you will be asked to validate a number of issues, including changes in your physical condition. Don't wait until being asked. Tell your recruiter now. Shouldn't be a big deal at all.
