Understanding the Different Types of Dental X-Rays

Dental X-rays are a helpful part of maintaining a healthy smile. They allow your dentist to see areas that are not visible during a regular exam, like what is happening between your teeth or below the gums. There are several types, each with a specific purpose, and all are designed to support your care using low-exposure imaging.

Bitewing X-Rays

These are the ones most people are familiar with. Bitewings show the upper and lower back teeth in a single view, helping your dentist spot things like decay between the teeth or changes in bone levels. They are typically taken once a year during routine checkups, depending on your individual needs.

Panoramic X-Rays

A panoramic scan captures your entire mouth in one wide image, including the jaw, teeth, and surrounding structures. It is often used to monitor developing teeth, check wisdom teeth, or take a broader look at your oral anatomy. Since it covers a lot in one image, it can be especially helpful during early assessments or treatment planning.

What to Expect

Dental X-rays use very low levels of radiation, and your dental team follows guidelines to keep exposure to a minimum. You may be given a lead apron to wear and asked to stay still for just a few moments. Most types are quick and easy, and your dentist will let you know if any images are needed. (You might not need them at every visit.)
