CBCT

What Is a CBCT Scan? (The 3D Vision Your Dentist Needs)

Remember those flat, black-and-white X-rays where your dentist would squint and say, "I think I see something"? A CBCT scan is like upgrading from a flip phone camera to the latest iPhone Pro. It’s a 3D imaging system that creates a complete, three-dimensional model of your teeth, jaw, nerves, and bone structure.¹

Think of it this way: a traditional X-ray is like a single photograph of a house. A CBCT scan is like a full 3D architectural model you can walk through, spin around, and inspect from every conceivable angle.² For complex dental cases, this level of vision is a game-changer.

When Is 3D Imaging Necessary for a Crown?

Let's be clear: most simple, straightforward crowns do not require a CBCT scan. However, there are specific situations where being able to see in 3D is the difference between a crown that lasts 20 years and one that is doomed to fail.

We recommend a CBCT scan when:

A previous root canal is involved. A 3D scan can verify if the original treatment was fully successful or if a hidden infection is lurking that could compromise your new crown.³

We suspect a hairline crack. These "tooth termites" are often invisible on 2D X-rays but become clear as day in a 3D view. Crowning a cracked tooth without knowing the extent of the fracture is a recipe for failure.
There is unexplained pain. When a tooth hurts but regular X-rays show nothing, a CBCT scan can often reveal the hidden culprit.⁴

An implant crown is planned. A CBCT is essential for assessing the quality and quantity of bone to ensure a solid foundation for the dental implant.⁵

The Patient Experience: A 14-Second Scan

Getting a CBCT scan is incredibly simple and fast.⁶

You will sit or stand in an open machine.
An arm will rotate around your head one time.
The scan itself takes less than 20 seconds.

That’s it. You feel absolutely nothing. Patients are consistently surprised at how quick and easy it is.

Let's Talk About Radiation

This is a valid concern for many patients. It’s important to put the numbers in perspective. The radiation dose from a focused dental CBCT scan is very low, roughly equivalent to the natural background radiation you receive during a cross-country flight. We always use the smallest possible field of view to get the necessary information while minimizing exposure. The diagnostic benefit in complex cases far outweighs the minimal risk.⁷

How 3D Imaging Protects Your Investment

A CBCT scan before placing a crown in a complex situation is like getting a home inspection before you buy. It’s a small upfront investment to prevent a huge, expensive problem later. By identifying hidden infections, fractures, or extra nerve canals before we place your beautiful new crown, we can address the underlying issue first, ensuring your final restoration is built on a healthy, stable foundation.

Here's what we want you to remember:

A CBCT scan is a powerful 3D imaging tool that allows us to see your tooth and jaw with unparalleled detail.⁸ While not necessary for every crown, it is an invaluable diagnostic tool for complex cases, helping us to identify hidden problems that could compromise your final restoration.⁹

Every patient's situation is unique.

We don't recommend a CBCT scan for everyone. Our decision is based on your specific clinical situation, your dental history, and whether the 3D information will fundamentally improve the quality and longevity of your treatment.
