Well, they would handle it kind of like a general dentist on shore would do. Whether they determine before or after attempting to treat the problem, they would do as much as they could for the patient to relieve the pain and any infection until the patient could be referred to an endodontist. Since one of my jobs on our carrier was coordinating medical / dental care ashore while on deployments, I know we had to send out a few people for various dental procedures when we were near (off shore where we had planes flying to and from or when the ship would go pierside or anchor out) military institutions away from our home port. Now, in instances where this just cannot be done, then the dentist would use his/her discretion and treat the patient accordingly. Unfortuately, there may be times where taking a risk is all they can do in hopes of saving the tooth. If a tooth is dilacerated for instance, that is ot of the scope of most people's ability. But, if they feel they might have a chance to save the tooth without extraction, then they may try to save it. Otherwise, that is why we have an Oral Surgeon on board - to finalize the treatment once and for all. The military has changed a lot from WWII. Back then, if a tooth even looked like it was going to be a problem, they extracted it. Now, every attempt possible is given to save a tooth, but in the end, if there is no other option available, an extraction will occur.
