Digital X-Rays

Why Digital X-Rays Are Essential to Your Care

Digital X-rays are the eyes that let our Thrive Dental dentists see what cannot be seen with visual examination alone. About 30% of cavities develop between teeth, hidden from view. Gum disease advances silently beneath the gum line. Infections brew under crowns without obvious symptoms. X-rays catch these problems early, when treatment is simpler and less expensive.

At Thrive Dental, we use cutting-edge digital X-ray technology with advanced safety features to provide precise diagnosis with minimal radiation exposure.

The Shift from Film to Digital X-Rays

Traditional film X-rays require chemical processing and take 20-30 minutes to develop. Digital X-rays are captured instantly on an electronic sensor and appear on a computer screen immediately. We can zoom in, adjust contrast and brightness, and measure tooth structures with pixel precision.

Radiation Comparison: Digital X-rays use up to 90% less radiation compared to traditional film X-rays, according to the American Dental Association. Specifically:

• Traditional film X-ray: 0.15 millisieverts (mSv) per image
• Digital X-ray: up to 0.03 mSv per image (90% reduction according to ADA standards)
• Full mouth digital series: 0.1-0.2 mSv total

For perspective, your annual background radiation exposure (from natural sources) is about 3 mSv. A cross-country flight exposes you to 0.04 mSv. Dental X-rays are one of the lowest-risk imaging procedures.

Types of Digital X-Rays We Use

Bitewings: Small X-rays showing the crowns of teeth and the bone between them. Bitewings detect cavities between teeth and reveal bone loss from gum disease. We typically take 4 bitewings (one for each side of the mouth, upper and lower).

Periapical X-rays: Full-tooth X-rays showing the crown, root, and surrounding bone. These detect root infections, implant position, and bone loss around tooth roots. New patients typically receive a full series of 14-20 periapical X-rays.

Panoramic X-rays: A single image showing all teeth, the entire jaw, and the TMJ. Panoramic X-rays reveal wisdom tooth position, jaw fractures, cysts, and large lesions. New patients and those with wisdom tooth concerns get panoramic X-rays.

Cone Beam CT (CBCT): 3D imaging for complex cases—implant planning, severe bone loss, jaw surgery, impacted teeth. CBCT provides detailed 3D reconstruction with high precision but uses more radiation than 2D X-rays, so we reserve it for cases where the benefit justifies the exposure.

The Digital X-Ray Process

Positioning: We position your head on a rest, angle the X-ray sensor, and ask you to hold still for about one second.

Exposure: The X-ray passes through your teeth and is captured digitally. The sensor is very sensitive, so exposure time is minimal (0.1-0.2 seconds).

Protection: We use a lead apron to shield your body and a thyroid collar to shield your neck—the most radiosensitive area.

Instant Review: The X-ray image appears on our screen immediately, and we discuss findings with you during your appointment.

What Digital X-Rays Can Reveal

• Cavities: Early decay between teeth or under existing fillings
• Bone Loss: Recession from gum disease or aging
• Root Infections: Abscesses or failed root canals needing retreatment
• Impacted Teeth: Wisdom teeth or other teeth stuck under bone or gum
• Fractures: Cracks or breaks in teeth
• Cysts and Tumors: Abnormal growths in bone
• Dental Anomalies: Extra teeth, missing teeth, supernumerary teeth
• Implant Planning: Bone density and dimensions for implant placement
• Periodontal Disease: Severity and progression of gum disease

Radiation Safety at Thrive Dental

We take radiation protection seriously:

• State-of-the-art equipment: Our digital sensors require minimal exposure time
• Protective shielding: Lead aprons and thyroid collars for all X-rays
• Selective use: We take X-rays based on clinical need, not routine
• Digital processing: Enhanced images require less radiation than film to achieve diagnostic quality
• Transparent communication: We discuss findings and explain why X-rays are necessary

X-Ray Frequency: How Often Do You Need Them?

New Patients: A full mouth series establishes a baseline for comparison in future years.

Low-Risk Patients: Those with excellent home care, healthy gums, and no decay history typically need bitewings annually or every two years.

High-Risk Patients: Those with gum disease, multiple cavities, or heavy plaque accumulation may need X-rays every 6-12 months.

Symptomatic Patients: If you report pain, we take focused X-rays to diagnose the problem.

Your Thrive Dental dentist individualizes X-ray frequency to your specific needs and risk factors.

Special Situations

Pregnancy: Routine X-rays are postponed until after pregnancy. Emergency X-rays (for pain or infection) can be taken with full shielding if necessary.

Children: We take X-rays less frequently in children because their teeth erupt rapidly. Bitewings are typically taken every 1-2 years; full mouth series less often.

Braces and Implants: Metal orthodontics or implants can create artifacts on X-rays that make interpretation difficult. We discuss these limitations.

Schedule Digital X-Rays at Thrive Dental

At any of our five Northern California locations—Dixon, Elk Grove, Yuba City, Stockton, or Santa Clara—we combine digital X-rays with thorough clinical examination and patient education to deliver complete, proactive diagnosis.
