Types of Dental X-Rays
- Bitewing X-rays: Detect cavities between teeth and bone loss.
- Periapical X-rays: Show the entire tooth, including roots and surrounding bone.
- Panoramic X-rays: Provide a full view of the mouth, useful for wisdom teeth and jaw issues.
- Cone Beam CT (CBCT): A 3D scan used for complex cases like implants.
Common Findings on a Dental X-Ray
1. Cavities (Tooth Decay)
- Appear as dark spots or shadows on the enamel or dentin.
- Early decay may not be visible without X-rays.
2. Gum Disease (Periodontal Disease)
- Bone loss around teeth, visible as lower-than-normal bone levels.
- Advanced cases show tooth mobility and deep pockets.
3. Impacted Teeth
- Common in wisdom teeth, where the tooth fails to fully erupt.
- May require extraction if causing pain or misalignment.
4. Infections & Abscesses
- Appear as dark, circular areas at the tooth root.
- Can indicate the need for a root canal.
5. Bone Loss & Jaw Issues
- Often linked to periodontal disease, osteoporosis, or trauma.
- Severe cases may require grafting or surgery.
6. Dental Restorations
- Fillings, crowns, and implants show as bright white on X-rays.
- Helps dentists assess their condition and fit.
7. Cysts & Tumors
- Unusual dark or light areas may indicate benign or malignant growths.
- Further tests like CBCT or biopsy may be needed.
What to Do After Reviewing Your X-Rays
- Discuss results with your dentist.
- Follow recommendations for treatment or preventive care.
