When do you need a CBCT scan? If your dentist has recommended one, you may be wondering why a regular dental X-ray isn’t enough.
The answer comes down to the level of detail needed to diagnose certain dental conditions and plan treatment accurately. While traditional dental X-rays remain an important part of dental care, some situations require a more detailed view of the teeth, jawbone, tooth roots, nerves, sinuses, and surrounding structures.
A CBCT scan (Cone Beam Computed Tomography) produces detailed three-dimensional images that allow your dentist to examine your oral structures from multiple angles. This can make diagnosis and treatment planning more precise, particularly for complex dental procedures.
At Luxe Dental, CBCT imaging is available in Lagos to support accurate diagnosis and personalised treatment planning when clinically appropriate.
In this guide, we’ll explain when a CBCT scan is needed, what it can help your dentist see, what happens during the scan, and how it can support safer and more predictable dental treatment.
What Is a CBCT Scan?
A CBCT scan is an advanced type of dental imaging that uses a cone-shaped X-ray beam to create detailed 3D images of the structures inside your mouth and jaw.
Depending on the area being examined, a CBCT scan can provide information about your:
- Teeth
- Tooth roots
- Jawbone
- Nerves
- Sinuses
- Temporomandibular joints (TMJ)
- Surrounding facial structures
Traditional dental X-rays produce two-dimensional images. CBCT, on the other hand, allows your dentist to view the anatomy in three dimensions.
This additional information can be particularly useful when a dentist needs to understand the exact position of a tooth, assess available bone, identify the location of a nerve, or plan a complex procedure.
However, not everyone needs a CBCT scan. Your dentist should recommend one when the additional information is likely to improve diagnosis, treatment planning, or patient safety.
When Do You Need a CBCT Scan?
A CBCT scan may be recommended when a traditional dental examination or X-ray doesn’t provide enough information for your dentist to make an accurate diagnosis or plan treatment.
Here are seven common situations where 3D dental imaging may be useful.
1. Before Dental Implant Treatment
Dental implant treatment requires careful planning because the implant must be positioned within the jawbone while avoiding important anatomical structures.
A CBCT scan can help your dentist evaluate:
- The height and width of available bone
- The condition of the jawbone
- The location of important nerves
- The position of the sinuses
- The position of neighbouring teeth
- The ideal location and angulation for implant placement
This information allows your dental team to plan implant treatment around your individual anatomy rather than relying solely on a two-dimensional image.
If you’re considering implants, you can learn more about CBCT scans for dental implants and how 3D imaging contributes to treatment planning.
2. Before Wisdom Tooth Removal
Wisdom teeth can sometimes become impacted, grow at an unusual angle, or develop close to important nerves.
A standard dental X-ray may provide useful information, but a CBCT scan can provide a more detailed three-dimensional view when the relationship between the tooth and surrounding structures needs closer assessment.
Your dentist may recommend a CBCT scan before complex wisdom tooth removal to evaluate:
- The exact position of the wisdom tooth
- The shape and number of its roots
- Its relationship to nearby nerves
- The surrounding bone
- The safest approach for removal
This can help your dentist anticipate potential challenges before the procedure begins.
3. For Complex Root Canal Treatment
Root canal treatment involves treating the inside of a tooth, including its root canals. While many routine cases can be assessed using conventional dental X-rays, some teeth have anatomy that is difficult to evaluate using two-dimensional imaging alone.
A CBCT scan may be useful in complex cases involving:
- Unusual or curved root canals
- Additional canals
- Persistent infection
- Previous unsuccessful root canal treatment
- Suspected root fractures
- Complicated tooth anatomy
The detailed images can help your dentist understand the tooth’s anatomy and identify potential problems that may otherwise be difficult to detect.
4. To Investigate Dental Problems That Are Difficult to See
Some dental problems aren’t immediately obvious during a routine examination or on a conventional X-ray.
When your dentist suspects an underlying problem that requires more detailed imaging, a CBCT scan may help investigate conditions such as:
- Certain dental infections
- Bone abnormalities
- Suspected root fractures
- Cysts or lesions
- Unusual tooth development
- Changes in the jawbone
The purpose isn’t simply to produce a more detailed image. It’s to provide information that can help your dentist determine what’s causing a problem and decide what treatment, if any, is appropriate.
5. For Certain Orthodontic Cases
Most orthodontic patients don’t automatically need a CBCT scan.
However, 3D imaging may be recommended in certain cases where your dentist or orthodontist needs additional information about tooth position, impacted teeth, jaw structures, or the relationship between the teeth and surrounding bone.
A CBCT scan may be considered when planning treatment for patients with:
- Impacted teeth
- Complex tooth positioning
- Certain bite problems
- Unusual jaw anatomy
- More complicated orthodontic cases
This can be particularly helpful when detailed information is needed to create a more predictable treatment plan.
If you’re considering clear aligners, your dentist will first assess your individual case and determine which diagnostic records are necessary for your treatment.
6. To Investigate Certain Jaw or TMJ Problems
Jaw pain can have several possible causes, and not every case requires advanced imaging.
However, when your dentist needs to assess the bony structures of the jaw or temporomandibular joints, a CBCT scan may provide useful information.
It can help your dental team evaluate certain structural changes and better understand the anatomy around the jaw joint.
If you’re experiencing persistent jaw pain, clicking, difficulty opening your mouth, or discomfort when chewing, a professional assessment can help determine whether additional imaging is necessary.
7. Before Certain Oral Surgery Procedures
Some oral surgical procedures require detailed knowledge of the patient’s anatomy before treatment begins.
A CBCT scan may be recommended when planning procedures such as:
- Complex tooth extractions
- Bone grafting
- Treatment involving jaw lesions
- Certain corrective oral surgeries
- Other procedures where detailed anatomical information is required
By seeing the treatment area in three dimensions, your dentist or oral surgeon can better understand the structures involved and plan the procedure accordingly.
Why Doesn’t Every Patient Need a CBCT Scan?
More detailed imaging doesn’t necessarily mean better imaging for every patient.
For routine dental examinations and many straightforward procedures, a standard dental X-ray or clinical examination may provide all the information your dentist needs.
CBCT scans also involve exposure to radiation, so they should be used when the expected diagnostic benefit justifies the additional exposure.
Your dentist will consider factors such as:
- Your symptoms
- Your dental history
- The type of treatment being planned
- The information already available from other examinations
- Whether 3D imaging is likely to change diagnosis or treatment planning
The goal is to use the right imaging technique for the right clinical situation.

Is a CBCT Scan Safe?
CBCT scans are widely used in modern dentistry and can be performed safely when clinically indicated.
Because CBCT uses X-rays, it does involve radiation exposure. For this reason, dentists should recommend CBCT when the information it provides is important for diagnosis or treatment planning.
The amount of radiation can vary depending on the machine, settings, and area being scanned.
If you’re pregnant, think you may be pregnant, or have concerns about radiation exposure, let your dental team know before the scan.
Your dentist can explain why the scan has been recommended and whether it is appropriate for your specific situation.
What Happens During a CBCT Scan?
A CBCT scan is generally quick, non-invasive, and painless.
During the procedure:
- You’ll be positioned in the CBCT scanning unit.
- You’ll need to remain still while the scan is taken.
- The scanner rotates around your head to capture multiple images.
- The images are combined to create a detailed 3D view.
- Your dentist reviews the images and uses the findings to support your diagnosis or treatment plan.
The actual scan is usually completed very quickly, although the exact time can vary depending on the equipment and type of scan required.
There is no recovery period, so you can normally return to your usual activities immediately afterwards.
What Does a CBCT Scan Show That a Dental X-Ray Doesn’t?
The biggest difference is dimensional information.
A conventional dental X-ray provides a two-dimensional image, meaning structures can overlap in the image.
CBCT creates a three-dimensional view, allowing your dentist to examine structures from different angles and better understand their spatial relationship.
This can be especially valuable when assessing:
- The position of impacted teeth
- Jawbone dimensions
- Tooth roots
- Nerve pathways
- Sinus anatomy
- Complex dental anatomy
However, CBCT isn’t intended to replace conventional dental X-rays. Each imaging method has its appropriate uses.
