Bitewing X-Rays: Why We Take Them at Checkups
Looking in the mouth is not enough. Some of the most important dental problems start between teeth or under old dental work.
Illustration for patient education. Actual diagnosis requires Dr. Nguyen’s exam and appropriate imaging.
What Bitewing X-Rays Show
Bitewings show the crowns of upper and lower teeth together. They help detect decay between teeth, early bone loss, tartar, open margins, recurrent decay under fillings/crowns, and changes that may not hurt yet.
Are Dental X-Rays Safe?
The ADA explains that dental X-rays use very low radiation doses and that modern tools are designed to limit exposure. The decision to take X-rays should be based on each patient’s risk, symptoms, history, and clinical findings.
When CBCT Is Different
A cone beam CT is a 3D scan. It is not used for routine bitewing cavity checks. It may be recommended for implant planning, difficult root canal diagnosis, jawbone/sinus/nerve evaluation, trauma, or complex infection.
How SoftDental Technology Helps
Used when clinically needed to find cavities between teeth, bone changes, infection signs, and failing restorations.
3D imaging used selectively for complex diagnosis, implant planning, root anatomy, sinus/nerve location, and difficult infections.
Dr. Nguyen chooses technology based on symptoms, risk, X-ray findings, treatment complexity, and patient safety.
What Patients Should Watch For
Hidden decay
Finds cavities between teeth.
Bone level
Monitors periodontal support.
Old dental work
Checks crowns/fillings for leakage.
CBCT
3D imaging for selected complex cases.
Quick Comparison
| Image type | Best use | Patient message |
|---|---|---|
| Bitewing X-ray | Cavities between teeth, bone levels, crowns/fillings. | Common preventive diagnostic image. |
| Periapical X-ray | Root, abscess, one tooth problem. | Useful for tooth pain/infection. |
| Panoramic X-ray | Overall jaw, wisdom teeth, large anatomy. | Broad overview, less detail for small cavities. |
| CBCT | 3D bone, roots, sinus, nerve, implant planning. | Used selectively when 3D detail matters. |
What Happens at SoftDental
Assess risk
Cavity history, symptoms, age, gum disease, restorations.
Take image if needed
Digital imaging is used when clinically appropriate.
Review with patient
Show cavities, bone levels, or restoration problems.
Plan treatment early
Treat small problems before they become painful.
Digital X-rays help us find what the eye cannot see. The goal is early diagnosis, not unnecessary radiation.

ADA: Radiographic Imaging — dental radiography should be patient-specific; the ADA notes recommendations for 2-D and CBCT patient selection and states dental imaging is a minor contribution to total radiation exposure.
ADA MouthHealthy: X-rays — dental X-rays emit very low radiation doses and modern tools/techniques are designed to limit exposure.
CDC: About Dental Sealants — dental sealants protect against cavities for many years and are thin coatings applied to chewing surfaces of back teeth.
ADA MouthHealthy: Scaling and Root Planing — scaling and root planing is deep cleaning below the gumline used to treat gum disease.
Cleveland Clinic: Scaling and Root Planing — scaling and root planing removes plaque/tartar above and below gums and smooths roots; soreness/bleeding can occur.
ADA: Oral Cancer — early detection of oral potentially malignant disorders and oral squamous cell carcinoma can improve prognosis; biopsy remains the reference standard.
CDC: Dental Infection Control — dental settings should follow infection prevention practices, including sterilization/disinfection guidance.
Leica Microsystems: Dental Microscopes — dental surgical microscopy provides high magnification, illumination, and visualization for endodontics, restorative dentistry, implantology, prosthodontics, and oral surgery.
Align Technology: iTero Scanners — iTero intraoral scanners create high-resolution 3D scans and reduce the need for traditional impressions.
AAE: Cone-Beam Computed Tomography — CBCT provides 3D views of teeth and surrounding structures and can enhance diagnosis/evaluation/treatment in selected cases.
Due for exam and X-rays?
SoftDental uses digital X-rays when clinically appropriate and explains what they show in patient-friendly language.
