Dental X-rays are an essential part of diagnosing and monitoring oral health. They allow dentists to detect issues that are not visible during a clinical exam, including changes in bone, tooth structure, and between teeth.

What Is the Difference Between Traditional and 3D Dental X-Rays?
Traditional dental X-rays capture flat, two-dimensional images. They are useful for detecting cavities, evaluating bone levels, and monitoring routine changes over time. However, they overlap structures and limit depth perception.
A 3D dental X-ray, or CBCT scan, creates a three-dimensional image of the teeth and jaw. This allows the dentist to evaluate structures from multiple angles and understand their exact position and relationship to surrounding anatomy. It provides an additional wealth of information over traditional 2D X-rays.
How a CBCT Scan Works
Cone Beam Computed Tomography (CBCT) uses a rotating imaging system that captures multiple images from different angles. These images are combined to create a detailed 3D model of the teeth and jaw.
The scan is quick and comfortable. At Broda Family Dental, we use Planmeca Ultra Low Dose™ technology, which allows 3D imaging with very low radiation, typically even lower than traditional panoramic X-rays. In fact, it’s roughly 5 times less radiation than the annual dose for living at high elevation. This helps provide detailed images while keeping exposure as low as possible.
Conditions a CBCT Scan Can Detect More Clearly
A 3D image provides additional detail that can improve detection and evaluation of certain conditions.
Impacted Teeth and Eruption Problems
3D imaging shows the exact position and angle of impacted teeth. This helps determine whether they may affect nearby teeth, nerves, or require removal.
Bone Loss and Jaw Structure
A CBCT scan allows for precise evaluation of bone volume, density, and shape. This is important when assessing periodontal health or planning restorative treatment.
Implant Planning
A CBCT is standard of care for implant planning and placement. It’s also used for root canals and other procedures.
Infections and Abscesses
Many infections are not clearly visible on traditional X-rays. 3D imaging can show the exact location and extent of infection within the bone.
Root Fractures and Complex Anatomy
Small cracks or unusual root shapes can be difficult to detect on 2D images. A CBCT scan provides a clearer view of root structure and damage.
Sinus and Nerve Position
3D imaging helps identify the location of important structures such as nerves and sinuses. This is especially important when planning procedures in the back of the mouth.
TMJ and Airway
CBCT is used to visualize the anatomy and structures of the TMJ and to evaluate for airway problems. Traditional 2D imaging does not have the same diagnostic ability.
When a CBCT Scan Is Recommended
Dental scans are not needed for every visit. They are used when additional detail can improve diagnosis or treatment planning:
- Dental implant placement planning
- Evaluation of teeth for extraction
- Persistent pain with no clear cause
- Suspected infection or pathology
- Complex root canal cases
Advanced Imaging at Broda Family Dental
At Broda Family Dental, Dr. Broda uses ultra-low dose 3D imaging when it truly adds value, not as a routine scan. It provides a detailed view of bone and anatomy with low radiation exposure.
Imaging is chosen based on your needs and used to guide care, from implant planning to diagnosing unclear problems. The focus is clear answers, thoughtful recommendations, and treatment that fits you.

FAQs
How much does a CBCT scan cost in Colorado?
The cost for a CBCT scan in Colorado typically ranges from about $150 to $500, The exact cost depends on the size of the scan, such as a small, medium, or large field of view. Your dental team will review the exact cost with you before the scan is performed.
Does dental insurance cover CBCT scans in Colorado?
Dental insurance often covers CBCT scans when they are considered medically necessary for diagnosis or treatment planning. Coverage varies by plan, so your dental team will help verify your benefits and explain any out-of-pocket costs beforehand.
Is there a dentist near me that offers CBCT scans?
Many modern dental offices offer CBCT imaging, but not all practices have this technology in-house. At Broda Family Dental in Boulder, CO, CBCT scans are available on site, allowing for detailed 3D imaging without the need for an outside referral. This helps streamline diagnosis and treatment planning in a single visit.
