Dental X-Rays and Why We Take Them
Dental X-Rays (Radiographs) are images that we use to evaluate the health of individual teeth.
These radiographs are used with low levels of radiation to capture images of the interior of your teeth and gums. This can help us detect abnormalities such as tooth decay, developmental issues or any infection associated with your child’s teeth. Often these abnormalities are not visible to the naked eye.
Are they safe and does my child need radiographs?
Regardless of whether you’re a child or an adult, you can have radiographs safely taken of the inside and outside of your mouth. The amount of radiation involved is extremely low.
If there is little benefit in taking a radiograph, or it does not affect immediate treatment, we may often choose not to take one.
However, cavities between teeth are best caught early. If you wait until you can see it without an X-ray, it could cause more serious damage to the teeth.
What can radiographs help to detect?
- Decay between teeth
- Abscesses and dental infections
- Normal and abnormal development of teeth – Malformed teeth, extra or missing teeth, stage of development of teeth
- Cysts and some types of tumours
- Traumatic dental injuries
- The proximity of teeth to nerves and sinuses
