Dental X-rays help your dentist see what is happening beneath the surface -- between teeth, under fillings, and inside the bone that supports your smile.
What Dental X-Rays Show That a Visual Exam Can't
X-rays help detect problems that are invisible during a visual examination:
- Cavities between teeth or under existing fillings
- Bone loss caused by gum disease
- Infections or abscesses near tooth roots
- Impacted teeth or abnormal development
- Cracks, cysts, and other changes in bone structure
Are Dental X-Rays Safe?
Modern X-rays deliver about the same radiation exposure as a short airplane flight or a day in the sun. Our practice follows the "As Low As Reasonably Achievable" (ALARA) principle using digital sensors that reduce exposure by up to 90% versus traditional film, protective shields like lead aprons and thyroid collars, selective imaging protocols, and regular equipment calibration.
How Often Do You Need X-Rays?
- Low-risk adults: Bitewing X-rays every 12-24 months
- Higher-risk adults: Every 6-12 months
- Children and teens: Varies by growth and cavity history
- New patients: Complete baseline set
X-Ray Types Explained
Bitewing
Detects cavities between back teeth and assesses bone levels.
Periapical
Captures the entire tooth from crown to root.
Panoramic
Shows the entire mouth, jaws, sinuses, and developing teeth.
When Is a 3D CBCT Scan Helpful?
Cone Beam Computed Tomography (CBCT) provides 3D imaging for complex cases:
- Planning dental implants and evaluating bone quality
- Diagnosing complex root canal problems
- Assessing impacted teeth or jaw joint concerns
- Analyzing airway and bite relationships
Safety for Pregnancy, Children, and Medically Complex Patients
For pregnant patients, non-urgent X-rays are postponed; emergency imaging uses protective coverings. For children, we use smaller sensors, quick exposures, and kid-friendly explanations. For medically complex patients, we coordinate with physicians for safety.
Common Questions About Dental X-Rays
Do X-rays hurt?
No. You might feel slight pressure from the sensor, but the process is painless.
Can I refuse X-rays?
Patients can discuss their preferences, but skipping necessary images limits diagnostic accuracy.
Are X-rays covered by insurance?
Most dental insurance includes routine X-rays in preventive coverage.
Can you use my previous X-rays?
Yes -- patients can send previous images before their visit.
