How can clinicians improve dental photography consistency in practice?

This article originally appeared on Dentistry.co.uk.

Clinical photographer Laura Short, in collaboration with DB Orthodontics, explores why dental photography still falls short in many practices - even when experienced clinicians are behind the camera.

In this three-part series, Laura shares practical insight from a hospital clinical photography setting, examines the common challenges faced by dental teams, and explains how the right systems and tools can help clinicians capture repeatable, high-quality images.

Dental photography has been widely discussed in dentistry for years. Most clinicians learned the fundamentals early in their careers, invested in a camera setup and ring flash, and assumed that was enough.

Yet, despite the availability of guidance and equipment, the same avoidable issues continue to appear in clinical images across practices.

So perhaps the more relevant question today is not whether dental photography matters, but how practices can consistently produce accurate and standardised clinical images.

Why is dental photography important in modern dentistry?

Clinical photography is an essential part of modern dental care. According to NHS Health Careers, clinical photography involves the daily recording of clinical conditions to support diagnosis and document treatment over time. In dentistry, photography supports:

  • Diagnosis and treatment planning

  • Monitoring orthodontic tooth movement

  • Periodontal assessment

  • Surgical documentation

  • Teaching and research

  • Medico-legal record keeping

From orthodontists and dentists to therapists and dental nurses, consistent photography improves communication and patient care across the entire clinical team.

How have patient expectations changed dental photography?

While the fundamentals of dental photography remain the same, expectations have evolved significantly. Patients today are highly visually aware. Social media, treatment galleries, and before-and-after case presentations have raised expectations around clinical imagery. Images are now frequently used for:

  • treatment explanations

  • case acceptance discussions

  • treatment progress monitoring

  • patient education

Consistency is therefore no longer simply desirable - it is critical, particularly when considering medico-legal documentation. Photography is no longer just a record. It is a communication tool. And communication only works when images are accurate, repeatable and comparable over time.

Why does dental photography still go wrong in many practices?

In my experience as a clinical photographer working daily in a hospital environment, the most common issue is not the camera itself. It is lack of planning and consistency. Common problems include:

  • inconsistent patient positioning

  • variable camera distances

  • unreliable retraction

  • poorly performing photography accessories

Clinicians do not need to become professional photographers to capture excellent clinical images. However, a reliable system must be in place. If changes cannot be measured accurately across photographs, the images are not serving their clinical purpose.

How does standardisation improve clinical photography?

Standardisation is the key to making clinical photography clinically useful. According to GOV.UK, standardisation provides clear rules and guidelines that allow results to be reproduced consistently. In dental photography, this ensures images can be:

  • repeated reliably

  • compared throughout treatment

  • used confidently for diagnosis and documentation

Professional guidance is available through the Institute of Medical Illustrators, which provides best-practice frameworks for clinical imaging. However, every practice should ideally develop its own agreed protocol, based on IMI guidance, to ensure every member of the dental team captures images in the same way.

How should consent and GDPR be managed in dental photography?

Consent is a fundamental requirement of clinical photography. Patients must provide informed consent before images are taken, and they must understand how the images may be used. This may include:

  • clinical records

  • teaching

  • research

  • publication

Consent processes must also comply with GDPR data protection regulations. Many hospitals and dental departments – including Birmingham Dental Hospital – use dedicated clinical photography consent forms to ensure this process is clear and documented. A structured approach protects both patients and clinicians.

What camera equipment is recommended for dental photography?

Capturing high-quality intra-oral and extra-oral images requires a suitable camera setup. Typically, this includes:

  • a DSLR or mirrorless camera body with manual controls

  • a true macro lens (usually 100mm or 105mm)

  • a macro ring flash for even lighting

Macro lenses reduce distortion and provide the magnification needed for accurate clinical imaging. Ring flashes help deliver consistent illumination for facial views, intra-oral images and surgical documentation. Understanding exposure is also essential:

  • Aperture controls depth of field

  • Shutter speed influences motion blur

  • ISO affects sensor sensitivity

In clinical photography, aperture and shutter speed should generally remain consistent. If exposure adjustments are needed, it is usually better to adjust ISO first, helping maintain image sharpness and repeatability.

How can clinicians achieve accurate colour in dental photographs?

Accurate colour reproduction is crucial, particularly when assessing tooth shade and soft tissue health. A standardised white balance setting - usually set to flash or custom-matched to the flash unit - helps ensure colours are reproduced accurately. Incorrect white balance can lead to:

  • misleading shade matching

  • inaccurate soft tissue appearance

  • compromised clinical records

                        Correct white balance                                         Incorrect white balance

Framing and focusing also play an important role. Magnification should be set using the lens scale, while focus is achieved using a gentle rock-and-pull motion, rather than continuous refocusing. The camera should remain parallel to the teeth, and images should be reviewed on playback before moving to the next view.

A simple guideline often helps:

  • “Smiling” teeth suggest the camera is too high

  • “Frowning” teeth suggest it is too low

What standard dental photographic views should practices follow?

Many clinical departments rely on defined photographic sets to ensure consistency. For example, Birmingham Dental Hospital commonly uses:

  • Standard Orthodontic View 10 – including facial views

  • Standard Orthodontic View 5 – without facial views

Following a defined photographic sequence ensures:

  • essential views are never missed

  • images can be compared throughout treatment

  • clinical records remain complete and consistent

How do dental photography accessories affect image quality?

Even when clinicians follow correct protocols, photography accessories can significantly influence results. Issues such as:

  • retractors losing their shape

  • mirrors that are too short or rest on molars

  • reflective surfaces causing glare

can all compromise clinical images.

In many cases, photography does not fail because of technique - it fails because of unreliable equipment.

Which dental photography tools help produce reliable results?

In my daily clinical work, dependable photography accessories make a significant difference. My preferred setup includes:

  • Gold Series retractors that maintain their shape even after repeated autoclave cycles.

  • Black anodised aluminium palatal contrastors that reduce reflections and improve incisal detail.

  • Chrome-coated mirrors designed for high reflectivity and sharp intra-oral imaging.

These tools are supplied by DB Orthodontics and are designed for durability in busy clinical environments. In departments such as Birmingham Dental Hospital, where equipment is heavily used and repeatedly sterilised, reliability and longevity are essential. These are products I use daily and continue to trust for consistent results.

Why consistency is the real goal of dental photography

If dental photography is inconsistent, it becomes difficult to compare images over time - and therefore difficult to measure treatment progress accurately. Consistency, accuracy and repeatability are what transform photographs from simple images into valuable clinical records.

In Part 2 of this series, I will explore the most common dental photography mistakes I encounter in clinical practice - and explain how they can be corrected quickly.
