Many patients in Fremont ask the same question before scheduling a dental scan: "Are dental X-rays safe?"
The short answer is yes — when taken with modern equipment and proper protocols, dental imaging involves very low radiation and provides critical information for your oral health.
Why Patients Worry About Dental X-Rays
Radiation exposure sounds intimidating, especially with terms like "CT" or "CBCT." But the reality is that dental X-rays use only a fraction of the radiation of medical imaging and are performed only when clinically necessary. The benefits — accurate diagnosis, safer procedures, and early detection — far outweigh the minimal risk.
Comparing Dental X-Rays to Everyday Radiation
Radiation is a natural part of everyday life. We are all exposed to "background radiation" from the sun, soil, and even air travel.
- Panoramic X-ray ≈ 2–3 days of background radiation
- CBCT (Cone Beam CT) scan ≈ a few days to a few weeks of background radiation, depending on scan size
- Cross-country flight ≈ 3–5 days of background radiation
When you compare these numbers, it's clear that dental imaging is very safe and carefully managed.
Panoramic X-Rays vs CBCT Scans
Panoramic X-rays are 2D overview images used for routine check-ups, orthodontic evaluations, and wisdom teeth monitoring. They use an extremely low dose and are often part of regular dental care.
CBCT (Cone Beam Computed Tomography) scans provide detailed 3D images of teeth, bone, nerves, and sinuses. While the dose is higher than a panoramic X-ray, it's still much lower than a medical CT scan and only taken when detailed imaging is essential — such as for dental implants or oral surgery. CBCT scans require a referral from your dentist or specialist to ensure they are medically necessary and properly prescribed.
Our Approach: ALARA and Patient Safety
At Fremont Dental Imaging, we follow the ALARA principle — "As Low As Reasonably Achievable." That means:
- Tailoring scan size to the clinical need
- Using child-specific settings for pediatric patients
- Protecting with lead aprons and thyroid collars when appropriate
- Performing scans only with a valid referral and medical necessity
Every step is designed to maximize safety without compromising diagnostic quality.
Special Considerations: Children and Pregnancy
Dental imaging for children uses the lowest possible settings while still providing clear diagnostic images. CBCT scans are carefully adjusted for smaller anatomy.
For pregnant patients, imaging is generally avoided unless absolutely necessary. In emergencies, protective measures are always applied and we coordinate closely with your dentist or OB/GYN.
Costs and Insurance
Insurance often covers routine X-rays and may cover CBCT when medically necessary, such as for implant planning or oral surgery. For patients paying out-of-pocket, we provide flat-rate, transparent pricing with HSA/FSA acceptance and superbills for reimbursement.
