Dental X-rays are a powerful diagnostic tool that allow your dentist to see beneath the surface of your teeth and gums. By detecting issues that are invisible to the naked eye, X-rays help identify cavities, bone loss, infections, and developmental abnormalities before they become painful or costly.

How Dental X-Rays Work

When X-rays pass through your mouth, denser structures like teeth and bone absorb more radiation and appear lighter on the film. In contrast, soft tissues such as gums and cheeks absorb less and appear darker. This contrast allows your dentist to pinpoint hidden issues like:

• Cavities between teeth

• Bone loss from gum disease

• Infections at the tooth root

• Impacted teeth or cysts

• Developmental issues in children

How Often Should You Get Dental X-Rays?

There’s no one-size-fits-all answer. The frequency of dental X-rays depends on your age, oral health, history of dental problems, and current symptoms. For example:

• Children may need X-rays more often due to developing teeth and higher cavity risk.

• Adults with good oral health may need them every 1–2 years.

• If you're experiencing pain, swelling, or other symptoms, X-rays may be taken immediately to aid diagnosis.

Before recommending X-rays, your dentist will assess your medical and dental history, conduct a visual exam, and consider your risk factors.

Are Dental X-Rays Safe?

Yes—modern dental X-rays use very low levels of radiation, and additional safety measures like lead aprons are always used. Digital X-rays further reduce exposure by up to 80–90% compared to traditional film.
