U.S. Air Force Senior Airman Jordan Barragan, 633rd Dental Squadron laboratory technician, uses tools to make a crown at the dental clinic at Langley Air Force Base, Va., July 10, 2013. Due to its range of specialties, the clinic provides most care in-house and does not refer patients to off-base care providers, saving them time and money.
