We use digital x-rays with small sensors (instead of traditional X-Ray film) and shorter exposure time to greatly reduce the amount of radiation exposure to our patients. Eating 5 bananas is about equivalent to the radiation you'd get from one digital dental x-ray. Airplane flights, background radiation and even eating carrots all cause more exposure than digital x-rays. That said, we take the very minimum number of images possible at all times to avoid unnecessary exposure to radiation. X-rays are an important diagnostic tool to make sure teeth, gums and bone areas in the jaw are all healthy. Without x-rays, some dental conditions will not be detected until they become a more serious problem. The US Nuclear Regulatory commission (NRC) website provides more information regarding radiation risks and daily exposure levels here.
