Radiographic, or x-ray, examination provide your dentist with an important diagnostic tool that shows the condition of your teeth, its roots, jaw placement and the overall composition of your facial bones. X-rays can help your dentist determine the presence or degree of periodontal (gum) disease, abscesses and many abnormal growths, such as cysts and tumors. They can pinpoint the location of cavities and other signs of disease that may not be possible with a visual examination.
Dental x-rays require exposure to very low levels of radiation, which makes the risk of potential harmful effects very small. Precautions are always taken to minimize your exposure to radiation.
