Dental x-rays are an important part of orthodontic treatment. Before beginning orthodontic treatment, your dentist will need to take x-rays of your mouth. It allows them to check for any underlying oral health problems that could impact the treatment. X-rays taken during treatment can also help monitor the treatment progress and that the teeth are moving as they should be. Finally, x-rays can be used to evaluate the results and the positions of your teeth once the treatment is completed. There’s no need to worry; dental x-rays are very safe. Modern x-ray machines use very low doses of radiation, and the risk of harmful effects from this exposure is extremely low.
