A dental cone beam CT (CBCT) scan is a fast, comfortable imaging exam that provides detailed 3D views of the teeth, jaws, and surrounding structures. These images help your provider diagnose conditions accurately and plan treatment with greater precision.
Below are a few common questions and helpful tips before your appointment.
- Do I need to share my medical history?
Yes. Please let us know about any significant medical conditions or implanted electronic devices (such as pacemakers or defibrillators), as well as if you are pregnant or think you may be pregnant.
Dental CBCT uses X-ray technology and does not involve magnets. In general, heart conditions and implanted cardiac devices do not prevent a patient from safely undergoing a CBCT scan. Sharing your medical history helps your provider ensure the exam is appropriate and tailored to your needs. - What if I am pregnant or breastfeeding?
Dental X-rays, including CBCT when clinically necessary, may be performed during pregnancy with appropriate precautions and radiation-minimizing protocols. Your provider will only recommend imaging when the diagnostic benefit outweighs potential risk.
Breastfeeding does not need to be paused or interrupted after a dental CBCT scan.
If you are pregnant or think you may be pregnant, please inform our staff prior to imaging. - Do I need to stop any medications or supplements?
No. There are no medication or supplement restrictions required before a dental CBCT scan. Please continue taking all prescribed medications unless your healthcare provider gives you specific instructions. - What if I have braces or dental appliances?
You do not need to remove fixed orthodontic appliances such as braces for your scan. While metal may cause minor image artifacts, CBCT scans can still usually be performed successfully.
If you have removable appliances (retainers, partial dentures, night guards), please bring them with you and our team will let you know if they should be removed during imaging. - How much radiation is involved?
CBCT uses a low dose of radiation, and the amount varies depending on the size of the area being scanned and the settings used. In general:- CBCT typically uses more radiation than standard 2D dental X-rays
- CBCT uses significantly less radiation than conventional medical CT scans
- Our equipment and protocols are designed to keep radiation exposure as low as reasonably achievable (ALARA) while still producing high-quality diagnostic images.
- How long does the scan take?
The scan itself takes only seconds, and most appointments are completed within about 10 minutes. You can return to normal activities immediately after your exam.
