As dental professionals, we often hear questions about dental X-rays from our patients. We understand that X-rays can seem a bit mysterious or even concerning to some. That’s why we’ve put together this article to address your top questions about dental X-rays. Let’s dive into the world of dental radiography and uncover why these important diagnostic tools are vital to maintaining your oral health.
1. What Are Dental X-Rays, and Why Are They Important?
Dental X-rays, also known as radiographs, provide a detailed look at your teeth, bones, and surrounding soft tissues. Using low levels of radiation, they capture images that give dental professionals a deeper insight into your oral health—far beyond what can be seen during a routine exam.
Consider dental X-rays as a powerful tool for uncovering hidden dental concerns. They help detect cavities, assess bone loss linked to gum disease, examine tooth roots and surrounding structures, monitor the development of children's teeth, and aid in planning treatments such as dental implants, braces, and other procedures.
2. How Often Should I Get Dental X-Rays?
How often one needs dental X-rays varies from person to person and depends on several factors, including your current oral health, age, risk for dental disease, and any signs and symptoms of oral disease.
As a general guideline, bitewing X-rays (which show the upper and lower back teeth) are usually recommended once every 12 to 36 months for adults with good oral health. Children and teenagers may need X-rays more often, as their teeth and jaws are still developing. If you have a history of gum disease, frequent cavities, or other dental issues, your dentist might recommend more frequent X-rays to monitor your oral health closely.

3. Are Dental X-Rays Safe?
We hear this question a lot, and we’re always happy to address it. In short, yes, dental X-rays are safe. The amount of radiation you’re exposed to during dental X-rays is extremely low, especially with modern digital X-ray technology.
To put it in perspective, a set of bitewing X-rays exposes you to about the same amount of radiation you’d receive from a short airplane flight or a day out in the sun. Plus, dental professionals take several precautions to ensure your safety, including using lead aprons and thyroid collars to protect your body from radiation. Modern digital X-ray technology reduces radiation exposure by up to 80% compared to film X-rays. Dentists also follow the ALARA principle (As Low As Reasonably Achievable), which means they only take X-rays when necessary.
4. What Types of Dental X-Rays Are There?
There are several types of dental X-rays, each serving a different purpose.
The most common ones you might encounter are:
- Bitewing X-Rays: Show the top and bottom back teeth in a single view.
- Periapical X-Rays: Display the entire tooth from crown to root tip.
- Panoramic X-Rays: Provide an overall view of the whole mouth.
- Occlusal X-Rays: Capture all the teeth in either the upper or lower jaw in one shot.
Each type of X-ray provides unique information, helping us provide you with the best possible care. Bitewing X-rays are great for detecting cavities between teeth and assessing bone structure, and periapical X-rays are useful for identifying deep dental problems. Dentists often rely on panoramic X-rays when planning treatments like braces or implants. Lastly, occlusal X-rays are particularly useful for detecting issues in children’s developing teeth.
5. Do Kids Need Dental X-Rays?
Yes, children often need dental X-rays, sometimes even more frequently than adults. Children’s teeth and jaws are constantly growing and changing, and X-rays help dentists monitor this development and catch any issues early. They can reveal problems with emerging teeth and ensure they’re coming in correctly. X-rays also reveal decay between teeth that might not be visible during a regular exam, and they help us determine if there’s enough space in the mouth for all the permanent teeth.

6. Can I Get Dental X-Rays While Pregnant?
Dental X-rays are generally considered safe during pregnancy, but your dental team will take extra precautions to protect you and your baby. Routine X-rays are usually postponed, especially during the first trimester, unless they are necessary for a dental emergency or critical treatment planning. In such cases, special protective measures—such as shielding your abdomen and thyroid—are used to ensure safety. Additionally, dental professionals utilize the fastest film speeds and collimated beams to minimize radiation exposure.
If you are pregnant or think you might be, be sure to inform your dentist. They will take every step to provide you with safe and effective dental care throughout your pregnancy.
7. How Do I Prepare for a Dental X-Ray?
Preparing for a dental X-ray is simple. Here are a few suggestions:
- Wear comfortable clothing.
- Remove all jewelry, eyeglasses, or metal objects from your head and neck area before the X-ray.
- Inform your dental team if you’re pregnant or think you might be.
- Feel free to bring up any concerns or questions about the procedure.
- Relax! The process is quick, painless, and crucial for maintaining your oral health.
During the X-ray, a dental professional will guide you through the process, telling you exactly how to position your head and bite down when necessary. The actual X-ray exposure only lasts a few seconds.
