Importance of Dental Photography in Modern Dentistry
Dental photography plays a key role in modern dentistry by improving diagnosis, treatment planning, and patient communication. Clear images help dentists explain oral conditions to patients, document progress, and collaborate with other professionals. These photos also support accurate record-keeping for legal purposes and long-term health monitoring, enhancing both dental care quality and patient understanding.
Types of Dental Photography
Dental photography is divided into two main categories: intraoral and extraoral photographs. Each serves specific purposes in documenting and assessing oral health.
Intraoral
Intraoral photography involves the capture of high-quality images inside the mouth. These close-up photos focus on teeth, gums, and other oral structures, which aid in diagnosing dental issues, planning treatments, and monitoring progress.
Dentists use specialized equipment like macro lenses and ring flashes to obtain detailed images that reveal conditions like cavities, fractures, and gum disease. These photos are valuable for patient education, allowing people to see and understand their oral health status.
Extraoral
Extraoral photography captures images outside the mouth, including the face and jaw. These photos provide a broader view of a patient's dental and facial structure, which is important for orthodontic assessments, cosmetic evaluations, and treatment planning.
Standard extraoral photos include full-face views, profile images, and smiling photos. These images help to analyze facial symmetry, tooth alignment, and the relationship between teeth and facial features.
Best Cameras for Dental Photography
You can choose between a Digital Single-Lens Reflex (DSLR) setup or a dedicated intraoral camera system (some of which may be able to take extraoral dental pictures too). Notably, selecting a high-quality camera is necessary to capture clear, detailed images that can support accurate diagnosis, effective treatment planning, and clear patient communication.
The following digital cameras are our top recommendations for digital photography in a dental practice:

Basic Camera Settings for Dental Photography
Don’t fall into the trap of setting your camera to “Auto” and leaving it. Taking some time to adjust the settings to those appropriate for clinical photographs will make a big difference to both extraoral and intraoral photos.
| Setting | Intraoral Recommended Values | Extraoral Recommended Values | Purpose |
|---|---|---|---|
| Aperture | f/22 to f/32 | f/8 to f/16 | – Intraoral requires deep focus for detailed shots – Extraoral balances depth of field with broader focus |
| Shutter Speed | 1/200s | 1/125s to 1/160s | – Higher speed for intraoral to avoid blur – Lower for extraoral to capture full-face clarity |
| ISO | 100 | 100 to 200 | – Low ISO for both – Extraoral may increase slightly to adjust lighting |
| Lens Requirement | Macro Lens (85 to 105 mm) | Standard Lens (50 to 85 mm) | – Macro lens for intraoral close-ups – Standard for broader extraoral shots |
| File Format | RAW | RAW or JPEG | – RAW offers best quality for both – JPEG is quicker for extraoral shots |
| Manual or Automatic | Manual Camera Setting | Manual Camera Setting | Allows for more control over your images |
Essential Dental Photography Accessories
Key accessories like cheek retractors, intraoral mirrors, and contrasters enhance clarity, contrast, and accessibility in dental photography. These accessories help professionals capture precise images for diagnosis and for putting a treatment plan together.
Cheek Retractors
Cheek retractors are available in clear plastic or metal and help to pull the cheeks away from the teeth and gums (retract the cheeks) during photography. This provides an unobstructed view inside the mouth, allowing for clearer images. Double-ended retractors offer the flexibility to accommodate various mouth sizes, which makes them useful for different patient needs.
Intraoral Mirrors (Occlusal Mirrors)
Intraoral mirrors are used to capture occlusal (biting surface) and lateral (side) views that may be hard to see directly. Pre-warming or defogging these mirrors prevents fogging during use, which is common due to the warmth and moisture in the mouth. Clear mirrors improve visibility and detail in the images, essential to accurately record a patient’s clinical condition.
Contrasters
Contrasters, typically made of black silicone or metal, are placed inside the mouth to create a dark background behind the teeth. This helps the teeth stand out sharply against the backdrop, making it easier to see fine details, assess shape and color, and enhance the contrast in the images.
Specialized Lighting
Specialized lighting, like ring flashes or LED lights, is extremely important for evenly illuminating the oral cavity. It helps minimize shadows and reflections, which can interfere with the details in the image. Even lighting is especially important in intraoral photography for capturing clear, accurate views of tooth surfaces and gums.
Remote Shutter Release
A remote shutter release allows the photographer to take photos without physically pressing the camera button, reducing the chance of camera shakes. This is highly beneficial for close-up shots or when using slower shutter speeds, as it helps maintain sharpness in the digital image. This is of particular importance when using a point-and-shoot camera or DSLR camera, rather than an intraoral camera.
Gray Cards
Gray cards are used to help set accurate white balance in photos. By including a gray card in a test shot, photographers can calibrate the camera’s color settings to reflect the true colors in the scene. This is important in digital dental photography to capture realistic tooth shades, especially when color matching is needed for procedures like restorative dentistry.
Direct and Indirect Photography Techniques
Direct photography captures images without mirrors, while indirect photography uses mirrors to take dental photos of areas that are hard to see directly. Notably, dental photography requires using both direct and indirect techniques to capture detailed images of a patient’s teeth and gums.
Direct Photography (Headshots and Frontal Retraction)
Direct photography includes full-face headshots and intraoral shots, like frontal retraction views, where images are taken directly without mirrors. This type of portrait photography is key for documenting the overall facial structure and front view of the teeth.
Positioning
For direct shots, such as headshots or frontal views, keep the camera parallel to the patient to avoid distortion. The patient’s head should be parallel to the floor (Frankfort horizontal plane), and the occlusal plane should also be parallel to the tabletop. In other words, the photo should be taken directly in front of the face.
Frontal Retraction
Use cheek retractors to pull back soft tissue, fully exposing the teeth. Position the camera directly in front of the patient at eye level to avoid any upward or downward angles that might distort the image.
Indirect Photography (Using Mirrors for Occlusal and Lateral Views)
Indirect photography uses mirrors to capture hard-to-see areas, such as the biting surfaces (occlusal views) and sides of the mouth (lateral views). This approach helps create a complete view of the mouth’s inner areas.
Mirror Positioning
For occlusal and lateral views, position the camera at a 45-degree angle to the mirror, and hold the mirror at a 45-degree angle to the teeth. This setup prevents distortion and helps capture a clear, accurate image of the dental arches.
Lateral Views
Double-ended retractors are useful for pulling back cheeks, allowing unobstructed views of side teeth. Position the mirror just behind the second molars for a clear view of the lateral teeth.
Practical Tips for Perfect Dental Photography
Achieving high-quality intraoral and extraoral photographs involves paying attention to lighting, preventing image distortion, correct positioning, and maintaining a consistent setup. Each of these areas contributes to capturing clear, detailed images useful for diagnosis and treatment planning.
Get Your Lighting Right
Using the right lighting equipment is key. Ring flashes or twin flashes provide even illumination, which helps reduce shadows and reflections on teeth.
When possible, combine natural light with flash systems to enhance the clarity and color accuracy of images. Avoid using overhead fluorescent lighting, as it can create unwanted glare and distort color.
Avoid Image Distortion
To avoid distortion in direct shots, keep the camera parallel to the patient’s head and teeth. This alignment helps avoid skewed images, maintaining accurate proportions.
For indirect shots using mirrors, positioning is also important. Hold the mirrors at a 45-degree angle to the teeth and align the camera accordingly to capture a true-to-life view of the dental arches without reflections.
Think About Positioning
Proper positioning improves both the comfort of the patient and the ease of capturing quality images. For extraoral shots, seat patients upright with their head in a neutral position.
For intraoral images, reclining the patient at approximately a 45-degree angle is effective. Position yourself at eye level with the patient for headshots or frontal views. For occlusal shots, stand in front of the reclined patient to maintain comfort and efficiency.
Standardize Your Setup
Keeping your setup consistent is important in dental photography. Use the same camera settings for all types of shots to keep image quality uniform.
Prepare your equipment carefully — check that retractors are positioned correctly, mirrors are free of fog, and lighting is stable. Standardizing these details helps you capture clear, professional images every time, which supports accurate documentation and effective communication with patients.
Post-Processing and Editing
Editing dental photos helps make them clearer and more accurate, which is important for documentation and communication with patients.
Basic Editing Techniques
Adjust exposure, contrast, and brightness to highlight details in the teeth and gums. Crop the image to focus on the main area, removing any distracting parts. Use sharpening tools to make features like tooth edges stand out. The goal is to keep the image looking natural while accurately showing the patient’s dental condition.
Ensuring Color Accuracy and Consistency
Accurate color is important in dental photos. Using a gray card during the photo session helps set correct color balance, so colors look true to life.
When editing, make sure your screen is calibrated to keep colors consistent across different devices. Adjusting color balance during editing can correct any color issues, helping the image accurately reflect the real color of the teeth and gums.
