Reimagining access to oral healthcare: The role of teledentistry in a changing landscape

Teledentistry has moved from the margins of dental practice into a more significant role in healthcare delivery. While its adoption accelerated during the COVID-19 pandemic, its continued relevance is driven by ageing populations, increasing chronic disease burden and persistent inequalities in access to care.

These pressures are particularly evident among older adults and individuals with functional limitations, many of whom face barriers such as mobility issues, reliance on caregivers, transportation difficulties and competing medical priorities.

Against this backdrop, teledentistry should not be viewed simply as a matter of convenience or technological novelty. Its greater value lies in its ability to reshape how oral healthcare is organised and delivered, moving beyond a predominantly clinic-based model towards one that is more connected and responsive to patient needs.

FROM EPISODIC USE TO EMERGING CARE MODELS

Early applications of teledentistry focused mainly on triage and preliminary consultations. Over time, its role has expanded to include follow-up care, preventive counselling, remote screening, case discussions and monitoring of oral conditions.

In Singapore, the Teledentistry Oral Care for Seniors (TDOCS) programme represents an early effort to integrate teledentistry into community care settings. The programme links nursing homes and home care environments with dental professionals through digital platforms, intraoral imaging and remote assessment. Trained community healthcare workers capture oral images, upload them to secure platforms and enable remote dental assessment and treatment planning. 

IMPROVING ACCESS FOR UNDERSERVED GROUPS 

The greatest value of teledentistry lies in improving access for elderly individuals, people with disabilities, homebound patients and medically complex individuals.

Transporting frail older adults to dental clinics often requires specialised transport, caregiver accompaniment and significant coordination. Consequently, oral problems may remain undetected until they become more severe.

Teledentistry enables clinicians to identify concerns earlier, provide guidance to care teams and determine whether face-to-face care is necessary. This helps reduce unnecessary transfers while allowing clinical resources to be prioritised for patients who require definitive treatment.

A qualitative study involving 43 community healthcare workers participating in TDOCS highlighted the programme’s potential to improve access, support earlier detection of oral problems and strengthen oral health capabilities within care teams. At the same time, challenges such as manpower constraints, unfamiliar technology, competing responsibilities and limited awareness of oral health were identified.

These findings demonstrate that teledentistry is not simply a technological intervention. Its success depends on training, workflows, organisational support and community engagement.

RECOGNISING CLINICAL BOUNDARIES

Despite its potential, teledentistry has clear limitations. Dentistry remains a highly hands on discipline, and many aspects of diagnosis and treatment, including radiographic imaging, periodontal assessment and operative procedures, cannot be performed remotely.

Teledentistry is therefore best suited to triage, preventive advice, follow-up care and support for community care teams. Patients experiencing acute pain, infection, trauma or complex restorative needs still require in person assessment.

The key question is not whether teledentistry can replace conventional care, but how it can be appropriately integrated through clear triage protocols, referral pathways and escalation criteria.

TECHNOLOGY AS AN ENABLER, NOT THE ENDPOINT

Digital technologies continue to expand the possibilities of teledentistry. Intraoral imaging, secure digital platforms and emerging artificial intelligence applications may support remote assessment, risk identification and prioritisation of patients requiring further care.

However, technology alone is insufficient. Systems must integrate into existing workflows and support practical clinical decision-making. The future of teledentistry lies in interoperable, user-friendly systems that support clinicians, community staff, patients and caregivers.

The TDOCS implementation study similarly highlighted the importance of training, workflow integration, programme champions and supportive policy frameworks to enable long-term adoption.

FROM PILOT TO PRACTICE: THE NEXT PHASE

Over the next decade, teledentistry is likely to become a routine component of oral healthcare delivery, particularly in community and long-term care settings.

Hybrid models that combine remote and face-to-face care may improve access, strengthen preventive care and help clinicians prioritise patients who require in person treatment.

Success should not be measured solely by the number of virtual consultations conducted, but by outcomes such as earlier access to care, timely intervention, appropriate referrals, improved patient experience and long-term sustainability.

Ultimately, teledentistry is not about technology itself. It is about improving access, equity and care coordination. The true measure of its success will be whether it enables appropriate oral healthcare to reach people who might otherwise go without it.

A SYSTEM-LEVEL OPPORTUNITY

Ultimately, teledentistry is not about technology. It is about access, equity and redesigning care around patient needs. For dependent older adults or the vulnerable seniors and other underserved groups, teledentistry offers a pathway towards earlier engagement, more timely advice and better coordination between community and dental care providers. For healthcare
systems, it creates an opportunity to shift from reactive, facility-based models towards more proactive, distributed and preventive approaches.

However, successful implementation requires realism. Teledentistry must be clinically safe, operationally feasible and supported by appropriate workflows, training and governance. It must also be developed with the people who will use it, clinicians, community healthcare workers, caregivers and patients.

The true impact of teledentistry will not be measured by how many virtual consultations are conducted. It will be measured by whether appropriate care can reach those who would otherwise go without it.

In that respect, programmes such as TDOCS offer an important foundation. They show both the promise of teledentistry and the work still needed to make such models sustainable. The next step is to move carefully and deliberately from pilot experience to integrated practice, with the right partners, the right evidence and a shared commitment to improving oral healthcare access.
