Dentists want to provide the best possible dental care to their patients, and for that, they use dental x-rays to provide more information about the teeth, gums and detect any early problems. There are different types of dental x-rays like bitewing, periapical, panoramic and OPG etc., are taken these days. The advances of medical imaging in dentistry has led to minimal exposure to radiation. Dentists always evaluate the need of having an x-ray done and to minimize the risk of radiation. It is essential to let your dentist know if you are pregnant or breastfeeding, so that, appropriate measures will be taken before exposing to radiation. If you any further queries, you can consult our dentists at our Blackburn North dental clinic.
