Why does the dental office take so many X-rays? Because each type answers a different question.
Let's start with the concern we hear most: radiation. Modern digital systems use remarkably low doses—less than what you'd absorb spending a day outdoors at the beach. From there, the choice of image depends entirely on what we're trying to see.
The small, high-definition images taken inside your mouth give us the fine detail needed to identify cavities at their earliest stages, when treatment is simplest and most conservative. Larger panoramic imaging, taken with the machine rotating around your head, captures the whole jaw and helps us screen for structural issues, infections, and other pathology that can develop without producing any pain at all. We typically repeat these every three to five years. A 3D scan is reserved for surgical planning and complex anatomy, letting us evaluate the tooth and jawbone in every dimension for a more precise procedure.
Every image should have a reason behind it. We keep both the number and the type of X-rays to the minimum required to keep you healthy.
Have you ever wondered what your dentist is actually looking for on an X-ray?
