You brush, floss, and show up for cleanings—so when your dentist recommends X-rays, it’s fair to wonder why. If nothing hurts and everything looks fine in the mirror, do you really need them?

Yes—X-rays play a key role in preventive care. They help your dental team spot issues early, often before you’d notice any symptoms yourself. Even if your mouth feels fine, there could be signs of decay, infection, or bone changes that only an X-ray can reveal.

What X-Rays Can Reveal

While a visual exam tells us a lot, some things just aren’t visible to the naked eye. X-rays can show decay between teeth, infections near the root, bone loss, and even hidden damage under old fillings or crowns. They also help track changes over time and guide treatment plans with more precision.

In short, X-rays give a fuller picture of your oral health. Without them, it’s easy for small issues to go unnoticed—until they become bigger problems.

How Often Do You Need Dental X-Rays?

There’s no one-size-fits-all answer. Some people may need X-rays more often due to a history of decay or gum disease. Others with a lower risk might go longer between sets. Your dentist will consider your age, oral health, and any symptoms before making a recommendation.

Are Dental X-Rays Safe?

Yes, dental X-rays are safe—and the amount of radiation is extremely low. In fact, you get more radiation from daily life than from a single dental X-ray.

For example, you’re exposed to more radiation during:

• A short airplane flight
• Using your smartphone regularly
• Spending a day out in the sun

Most dental offices now use digital X-rays, which reduce radiation even further compared to traditional methods. Your dental team only recommends X-rays when they’re truly helpful—and when the benefits far outweigh any risks. If you ever have questions or concerns, they’re always happy to talk them through.
