The Dental Corps of the United States Navy consists of naval officers who have a Doctorate in either Dental Surgery or Dental Medicine (D.D.S. or D.M.D.) and who practice dentistry caring for sailors and marines. In overseas locations they also treat dependent family members. Dental officers are usually appointed to the rank of Lieutenant (O-3) but may be appointed at higher ranks with significant practice experience or advanced specialty training. Most attend the Officer Development School (ODS) at NETC Newport, Rhode Island, as opposed to the more well known accession training programs of Officer Candidate School (OCS), Reserve Officer Training Corps (ROTC), or the Naval Academy.
