X-rays, also known as radiographs, are an essential part of any dental care treatment plan. They are diagnostic, but they can also be preventative, by helping a dentist diagnose potential oral care issues in a patient’s mouth before they become a major problem. An x-ray is a type of energy that passes through soft tissues and is absorbed by dense tissue. Teeth and bone are very dense, that is why they absorb X-rays, while X-rays pass more easily through gums and cheeks.

X-rays are divided into two main categories, intraoral and extraoral. Intraoral is an X-ray that is taken inside the mouth. An extraoral X-ray is taken outside of the mouth.

Intraoral X-rays are the most common type of radiograph taken in dentistry. They give a high level of detail of the tooth, bone and supporting tissues of the mouth. These X-rays allow dentists to:

• Find cavities
• Look at the tooth roots
• Check the health of the bony area around the tooth
• Determine if periodontal disease is an oral care issue
• See the status of developing teeth
• Otherwise, monitor good tooth health through prevention

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, but however we avoid them if there is no emergency. Dental X-rays do not need to be delayed if you are trying to become pregnant or are breastfeeding.
