🦷 “That’s a lot of radiation…” We hear this all the time!
One of the most common reasons patients hesitate to get dental X-rays is concern about radiation. It’s a reasonable question, so let’s put it into perspective.
❓How much radiation is in a dental X-ray?
Digital dental X-rays expose you to a very small amount of radiation.
To compare:
✈️ A cross-country flight exposes you to more radiation from natural cosmic rays than many dental X-rays.
🌎 Every day, we’re exposed to natural background radiation from the sun, the earth, the air we breathe, and even the food we eat.
❓Why do I need X-rays if my teeth don’t hurt?
Not everything happening in your mouth can be seen by simply looking at your teeth.
X-rays help us diagnose problems that may not be visible yet, including:
• Cavities between teeth
• Bone loss from gum disease
• Infections or abscesses
• Cysts
• Problems under existing fillings or crowns
• Cracks that aren’t visible clinically
Finding these issues early often means simpler, less invasive, and less expensive treatment.
❓Why do you take X-rays after treatment?
X-rays aren’t only used to diagnose problems—they also help us confirm that treatment was successful.
We may take an X-ray to:
🦷 Make sure a new crown is fully seated.
🦷 Verify a filling has the proper contours and no excess material remains between the teeth.
🦷 Check that a dental implant is healing and integrating with the bone as expected.
🦷 Evaluate root canal treatment and monitor healing.
🦷 Confirm restorations fit properly before they become a bigger problem.
These images are an important part of delivering safe, high-quality dental care—not just treating teeth, but verifying that everything looks exactly as it should.
❓Can I skip my X-rays?
You always have the right to decline. However, without X-rays, your dentist may not be able to detect hidden problems or verify that treatment has been completed successfully. This could allow issues to go unnoticed until they become more serious.
💙 Your safety is always our priority.
We only recommend X-rays when they’re clinically necessary and use digital technology to keep radiation exposure as low as reasonably achievable (following the ALARA principle).
