Your dentist will examine your teeth and gums for signs of tooth decay, gum disease, and other health problems. Your dental hygienist will begin to clean your teeth by scraping hard mineral build up (tartar) off your teeth with a small metal tool. Then the hygienist will floss your teeth, use a polishing compound, and apply fluoride. Cleanings usually aren't painful. Sometimes your dentist will want to take x-rays. The x-rays will only take a few minutes.
Your dentist or technician will have you put on a heavy apron to shield your body from radiation. Everyone else in the room will either wear a protective apron or step behind a protective shield. Your dentist or technician will have you bite down on a small piece of plastic. This will help align your teeth properly for the machine. Your dentist or technician will repeat this process several times to get pictures of all your teeth.
