Dental X-rays can help a dentist see parts of the teeth and jaw that are difficult to assess during a visual exam. They may help identify concerns between teeth, around roots, or in the jaw, and can support diagnosis or treatment planning.
When might dental X-rays be recommended?
The decision depends on your oral health, symptoms, dental history, age, and the information needed for care. X-rays are not automatically required at every appointment. Your dentist should consider the clinical exam and any recent images that are available before recommending new ones.
Health Canada advises that dental X-rays be based on a clinical examination and used to obtain diagnostic information or help provide and monitor treatment. Read its overview of dental X-rays and radiation safety.
What can an X-ray show?
Depending on the type of image, X-rays may show decay between teeth, bone levels, tooth roots, developing or impacted teeth, or other changes that may not be visible to the eye. Your dentist can explain which image is being considered and what question it is meant to answer.
Are dental X-rays safe?
Dental X-rays use a low radiation dose, and the risk from an individual exposure is generally low. Dental professionals aim to limit exposure while obtaining the information needed for diagnosis. Tell your dentist if you are pregnant or may be pregnant, and mention any recent dental images taken elsewhere.
Questions to ask before an X-ray
- What are you looking for with this image?
- Could a recent X-ray from another clinic help answer the question?
- How will the result affect my diagnosis or treatment plan?
- Are there precautions I should share with you?
