Dental X-rays are a useful diagnostic tool when helping your dentist detect damage and disease not visible during a regular dental exam. How often X-rays should be taken depends on your present oral health, your age, your risk for disease, and any signs and symptoms of oral disease. For example, children may require X-rays more often than adults because their teeth and jaws are still developing and their teeth are more likely to be affected by tooth decay than those of adults. Dr. O’Malley will review your history, examine your mouth and then decide whether or not you need X-rays.
If you are a new patient, Dr. O’Malley may recommend X-rays to determine the present status of your oral health and have a baseline to help identify changes that may occur later. A new set of X-rays may be needed to help him detect any new cavities, determine the status of your gum health or evaluate the growth and development of your teeth. If a previous dentist has any radiographs of you, O’Malley Dental may ask you for copies of them.
Dental X-ray exams are safe. They require very low levels of radiation exposure, which makes the risk of potentially harmful effects very small. Dental X-ray tools and techniques are designed to limit the body’s exposure to radiation and every precaution is taken to ensure that radiation exposure is As Low As Reasonable Achievable (the ALARA principle). A leaded apron minimizes exposure to the abdomen and should be used when any dental radiograph is taken. Also, a leaded thyroid collar can protect the thyroid from radiation, and should also be used whenever possible. The use of a leaded thyroid collar is recommended for women of childbearing age, pregnant women, and children.
If you are pregnant, tell your dentist. During your pregnancy, you may need to have X-rays taken as part of your treatment plan for a dental disease. Use of the leaded apron and thyroid collar will protect you and your fetus from radiation exposure. Dental X-rays do not need to be delayed if you are trying to become pregnant or are breastfeeding.
