Peer Review in Dentistry: Why Having Multiple Specialists Assess Your Case Matters

When a patient sits in a dental chair, they typically assume that the clinician examining them is the sole decision-maker for their care. In a solo general practice, this is often true - one practitioner reviews the X-rays, forms a diagnosis, and presents a treatment plan, all within a single appointment. For straightforward cases, this model works well. For complex ones, it introduces a structural vulnerability that research now confirms carries measurable patient risk.

Peer review - the formal or semi-formal process by which a clinician's diagnostic findings and proposed treatment plan are assessed by one or more qualified colleagues before treatment commences - is one of the most powerful and underutilised patient safety tools in dentistry. Within a multidisciplinary specialist centre, it operates not as an occasional quality check but as a foundational element of every complex case assessment. This article explains what clinical peer review means in the dental context, why diagnostic error in dentistry is more common than most patients realise, and why having multiple board-registered specialists review your case before treatment begins is a genuine, evidence-supported advantage - not a marketing claim.

What Is Clinical Peer Review in Dentistry?

In the broadest sense, clinical peer review in dentistry involves the evaluation of a practitioner's diagnostic reasoning, treatment planning, and clinical records by one or more qualified colleagues, with the objective of identifying gaps, errors, or alternatives that may improve patient outcomes.

Peer review provides an opportunity for clinicians to review aspects of practice, with the aim of sharing experiences and identifying areas in which changes can be made with the objective of improving the quality of service offered to patients.

Regulators and health authorities have formally endorsed peer review as a quality standard. The Oral Health Regulation Strategic Leadership Forum (OHRSLF) recommends peer review as one way of maintaining good practice and preventing poor practice from emerging, and considers it one of the hallmarks of a well-led practice.

However, there is an important distinction that patients rarely appreciate: peer review as a quality assurance mechanism (reviewing past cases to audit performance) is categorically different from prospective peer review of a complex case before treatment commences. The latter - the collaborative, pre-treatment discussion of a patient's case by multiple specialists - is what occurs in a true multidisciplinary specialist centre, and it is this model that delivers the greatest direct benefit to the patient in front of you.

The Two Modes of Peer Review in Dentistry

The Collins Street Specialist Centre model is built around the second, higher-value form: prospective, multi-specialist case assessment for complex presentations.

The Scale of Diagnostic Error in Dentistry

To understand why peer review matters, it is necessary to first understand the scale of the problem it addresses.

In dentistry, very little is known about diagnostic errors despite their critical role in assessing patient safety, and many diagnostic error cases significantly impact the patient's quality of life and daily function.

The data that does exist is sobering. Of 58,229 dental paid malpractice claims analysed from the National Practitioner Data Bank, 8.7% were diagnostic claims, of which missed diagnoses (78.6%) were the most common type. This analysis, published in the Journal of the American Dental Association (Obadan-Udoh, University of California San Francisco, 2025), represents three decades of claims data - and missed diagnosis, not procedural error, was the dominant failure mode.

The problem is particularly acute in specific clinical areas. Research has found that about a third of dental patients may experience periodontal misdiagnosis, with a study revealing that about a third of periodontal cases are misclassified. This research, conducted by Tokede and colleagues at the University of California San Francisco and published in the Journal of Dentistry (2024), used electronic health record trigger tools followed by gold-standard manual review to estimate misclassification rates - and the findings are striking.

Diagnostic errors have been reported to happen more frequently than other types of errors, and to be more preventable.

The consequences for patients are not abstract. Dental patients have been found to endure prolonged suffering, disease progression, unnecessary treatments, and the development of new symptoms as a result of experiencing diagnostic errors, with poor provider communication, inadequate time with the provider, and lack of patient self-advocacy among the top contributing factors. A qualitative study from UT Health Houston School of Dentistry (published in Diagnosis, 2024) drew on 67 individual patient interviews to document these harms directly.

Diagnostic errors have been known to plague the dental profession, and in a retrospective review of 182 published case reports in dentistry, 23% of experiences were categorised as delayed appropriate treatment, disease progression, or unnecessary treatment associated with misdiagnoses.

Why Solo-Practitioner Decision-Making Creates Structural Risk

The diagnostic challenges inherent in dentistry are not primarily a reflection of individual incompetence - they are, in significant part, a reflection of the structural limitations of solo decision-making applied to inherently complex clinical problems.

The field of dentistry faces unique challenges with formulating proper diagnoses, as perceptual dispositions of imaging procedures, high patient volume, and incomplete patient histories make dentists more susceptible to diagnostic failures.

A diagnosis could be erroneous when the practitioner has lacked vigilance, and habit, routine, lack of involvement on the part of the practitioner - or, conversely, strong pressure from the patient - are common factors that can lead to a wrong diagnosis.

These cognitive biases - anchoring (locking onto an initial diagnosis), premature closure (stopping the diagnostic process too early), and availability bias (favouring diagnoses seen recently) - are well-documented in medical literature and apply equally to dental practice. They are most dangerous when a single clinician is both the diagnostician and the treating practitioner, with no independent review of their reasoning.

Research among dental teaching staff found that diagnostic errors are considerably associated with pitfalls in knowledge, critical thinking, and reasoning among many dental practitioners, with nearly 61% of participants believing that medical education strategies are blamed for diagnostic errors.

The structural solution to cognitive bias in complex clinical decision-making is not simply more training for individual practitioners - it is the introduction of a second (and third) expert perspective before treatment begins.

How Prospective Peer Review Works in a Specialist Centre

In a multidisciplinary specialist dental centre, prospective peer review of complex cases typically operates through a case conference or case discussion model. Before treatment commences, the treating specialist presents the patient's clinical findings, radiographs, diagnostic records, and proposed treatment plan to one or more colleagues from relevant specialist disciplines. The group identifies any diagnostic considerations that may have been missed, questions assumptions in the treatment plan, and ensures that the sequencing of care across specialties is clinically sound.

Comprehensive adult treatment mostly requires close collaboration of a team of equally well-trained dental specialists to select and execute the most suitable treatment option for the individual patient from day one, and with joint planning, intensive communication with the patient and the involved specialists, and continuous monitoring of the treatment process, true patient-centred care can be delivered. This principle, articulated in the British Dental Journal (2024), is foundational to the specialist centre model.

Treating patients to the highest standard of care requires more than a specialty degree but also sound knowledge of related dental and medical disciplines to jointly plan, select and execute the most appropriate treatment approach, and without close communication and continuous exchange of information between team members, interdisciplinary treatment is reduced to mere multidisciplinary care without coordination of the single procedures.

This is a critical distinction: simply having multiple specialists in a building does not constitute peer review. What matters is the structured, pre-treatment exchange of clinical reasoning - where each specialist's domain expertise actively challenges and refines the overall plan.

What Prospective Peer Review Catches That Solo Assessment Misses

In practice, multi-specialist case review routinely identifies issues including:

• Periodontal risk that undermines a restorative plan - a prosthodontist's proposed crown or implant work may be premature if a periodontist identifies active disease that must be stabilised first
• Endodontic prognosis affecting the restorative sequence - an endodontist may assess that a tooth proposed for crown restoration has a poor long-term prognosis, changing the entire treatment plan
• Orthodontic space requirements for implant placement - an orthodontist may identify that implant site development requires prior tooth movement that the surgical plan has not accounted for
• Oral medicine or pathology concerns - soft tissue findings that a restorative specialist might attribute to irritation may prompt an oral medicine specialist to recommend biopsy
• Systemic health interactions - a complex medical history may have implications across multiple treatment phases that no single specialist would be positioned to evaluate comprehensively

Interdisciplinary dental treatment planning is essential for delivering comprehensive care that addresses all facets of a patient's oral health; by integrating input from multiple dental professionals, a more precise, individualised treatment plan can be developed, ensuring that no aspect of the patient's condition is overlooked, and this method results in a more balanced approach to both function and aesthetics, improving the long-term success of treatments.

The Evidence for Collaborative Specialist Planning

The clinical literature consistently supports the superiority of collaborative specialist assessment over single-practitioner decision-making for complex cases.

Patients presenting with complex dental needs require an interdisciplinary team to address the maximum number of highest priority problems, including the patient's chief complaint, and to optimise the treatment results with the greatest benefit and the least risk by implementing evidence-based treatment approaches.

In a 2024 special issue of Medicina dedicated to multidisciplinary dentistry, published case evidence demonstrated that the movement towards a multidisciplinary, technology-driven approach touches upon various branches, including restorative dentistry, prosthodontics, oral surgery, implantology, paediatric dentistry, orthodontics, and the management of temporomandibular disorders. This breadth of specialties - all of which may be relevant to a single patient's complex presentation - underscores why no single clinician can be expected to hold equivalent expertise across all domains simultaneously.

The benefits of a team-based approach include better treatment accuracy, fewer errors, and a holistic understanding of the patient's condition. For example, an orthodontist can work alongside a periodontist to ensure that tooth alignment treatments do not compromise gum health. Similarly, an oral surgeon and prosthodontist can coordinate to ensure optimal placement of dental implants, and this comprehensive planning reduces the need for future corrective procedures and improves overall patient satisfaction.

Careful patient management, teamwork, and use of technology can reduce diagnostic errors. And as the oral surgery diagnostic error literature confirms, avoiding and stopping diagnostic errors can be achieved by developing collaborations between various specialties of dentistry.

Peer Review vs. Referral: Why Co-Location Changes Everything

A common misconception is that receiving specialist care through sequential referrals across independent practices is functionally equivalent to receiving care within a co-located specialist centre. For peer review purposes, it is not.

When a patient is referred from a general dentist to a periodontist, then separately to a prosthodontist, and separately again to an oral surgeon, each specialist typically receives only the information that has been forwarded to them. Each practitioner forms their own treatment recommendation in relative isolation. There is no structured mechanism for those three specialists to discuss the case together before any treatment commences, to challenge each other's assumptions, or to ensure that the sequencing of their respective interventions is clinically optimal.

Best practices for coordinating care involve clear communication and detailed planning, with regular case meetings between specialists, shared patient records, and a coordinated timeline for treatments helping to maintain consistency across various procedures. These conditions are structurally impossible when specialists are separated across independent practices with no shared infrastructure.

Teams within co-located specialist centres use advanced imaging, shared digital platforms, and case conferences for seamless treatment sequencing

• a capability that is practically absent in the fragmented referral model.

The patient experience implications are also significant. When your case is discussed in a pre-treatment specialist conference, you benefit from a treatment plan that has been stress-tested by multiple expert perspectives before a single tooth is touched. If the plan changes - because a periodontist identifies a risk that the implant surgeon had not flagged, or because the orthodontist's input changes the restorative sequencing - that change happens in a planning meeting, not in the middle of your treatment.

Peer Review as a Patient Safety Standard, Not a Premium Feature

It is worth being direct about something patients often do not know to ask: peer review of complex dental cases is not a premium service reserved for the most elaborate full-mouth reconstructions. It is the appropriate standard of care for any case that involves multiple treatment phases, multiple specialties, or significant clinical complexity.

Diagnostic errors have been reported to happen more frequently than other types of errors and to be more preventable, and benchmarking diagnostic quality is a first step, with subsequent research endeavours needing to focus on comprehending the factors that contribute to diagnostic errors and instituting measures to prevent them.

Quality improvement research from NHS Scotland, published in the British Dental Journal (2021), found that barriers to quality improvement in dentistry included time, poor patient and team engagement, communication and leadership, while facilitators included team working, clear roles, strong leadership, training, peer support, and visible benefits. In other words, the structural conditions that enable peer review - team working, clear specialist roles, and strong clinical leadership - are the same conditions that a well-organised specialist centre is built to maintain.

The continuous development of collaborative efforts across various disciplines and the necessity of ongoing education ensures that the dental profession remains a leader in medical advancements while adhering to the fundamental principles of high-quality care and patient welfare.

What to Ask Before Your Treatment Begins

Patients who understand the value of peer review are better positioned to advocate for their own care. Before committing to a complex treatment plan at any dental practice, consider asking:

1. Has this treatment plan been reviewed by specialists in each relevant discipline? A plan involving implants, periodontal treatment, and restorations should ideally reflect input from a periodontist, oral surgeon, and prosthodontist - not just the practitioner proposing the treatment.
2. What is the basis for the proposed treatment sequence? The order in which dental treatments are delivered matters clinically. Restorations placed before periodontal disease is stabilised are at risk of failure. Implants placed without orthodontic space planning may produce suboptimal aesthetic and functional outcomes.
3. Who else has reviewed my radiographs and diagnostic records? Diagnostic imaging review by a single practitioner is a known vulnerability. In a specialist centre, imaging is typically reviewed by clinicians with specialist-level training in the relevant anatomy and pathology.
4. Is there a case conference process for complex cases? Asking this question directly will quickly reveal whether Smile Solutions has a structured peer review model or whether treatment planning is a solo activity.

Key Takeaways

• Diagnostic errors are a recognised problem in dentistry, with a retrospective review of 182 published case reports finding that 23% involved delayed appropriate treatment, disease progression, or unnecessary treatment associated with misdiagnoses.

• Research has found that about a third of dental patients may experience periodontal misdiagnosis, with approximately a third of periodontal cases found to be misclassified in clinical studies.

• Without close communication and continuous exchange of information between team members, interdisciplinary treatment is reduced to mere multidisciplinary care without coordination of the single procedures

• a distinction that directly affects patient outcomes.

• Prospective peer review - the structured, pre-treatment assessment of a complex case by multiple specialists - is categorically more valuable to the current patient than retrospective audit-based peer review, which benefits future patients.

• Avoiding diagnostic errors can be achieved by developing collaborations between various specialties of dentistry , and co-located specialist centres are the only care model that makes this structurally reliable.

Conclusion

Peer review in dentistry is not a bureaucratic formality or a theoretical ideal - it is a clinically grounded response to the documented reality that diagnostic errors in dentistry are common, consequential, and preventable. The structural advantage of a co-located multidisciplinary specialist centre is precisely that it makes prospective peer review of complex cases a routine, embedded process rather than an exceptional one.

When multiple board-registered specialists - each with deep postgraduate training in their own discipline - review your case together before treatment begins, the probability of a missed diagnosis, an incorrect treatment sequence, or a plan that ignores a critical interdisciplinary interaction is materially reduced. That is not a marginal benefit. For patients facing complex dental treatment, it may be the single most important quality assurance mechanism available.

For patients considering specialist dental care in Melbourne, the Collins Street Specialist Centre at the Manchester Unity Building is built around exactly this model: board-registered specialists across multiple disciplines, working under one roof, with the infrastructure to review complex cases collaboratively before treatment commences.
