X rays are used to detect injuries to bones, such as breaks and dislocations, and to monitor the recovery from injuries. Chest x rays help doctors look at your heart and lungs, and to confirm a diagnosis of pneumonia, a collapsed lung or lung cancer. Dentists use them frequently to check teeth and bone under the gums. Some people worry about radiation, but when doctors and dentists order x ray pictures they take into consideration the minute risk and have decided that the value outweighs the risk.
