Teledentistry in the Era of Digital Dentistry: Clinical Applications, Patient Experience, and Equity-Oriented Policy Implications

Teledentistry has shifted from small pilot projects and emergency use during the COVID-19 pandemic to a realistic option for delivering parts of routine oral healthcare. However, its role in long-term service models, equity, and health-system performance remains incompletely defined. This narrative review aimed to provide an up-to-date synthesis of the evidence on teledentistry across clinical specialties, populations, and settings, and to discuss implications for practice, policy, and future research. Electronic databases were searched from inception to December 2025 for studies evaluating teledentistry or related digital remote dental services. Eligible sources included observational and interventional studies, reviews, economic evaluations, implementation reports, and key professional or policy documents. Data were organized thematically around clinical effectiveness, patient and provider experience, cost and resource use, equity and access, regulatory frameworks, and emerging technologies. Across settings, teledentistry supports accurate diagnosis and triage for selected indications, particularly in orthodontics, pediatric dentistry, and community-based screening. Most studies report gains in access, reduced need for travel, and high levels of patient satisfaction, especially in rural, institutionalized, and otherwise underserved groups. Evidence for long-term clinical outcomes, cost-effectiveness, and the impact on oral-health inequities is promising but remains heterogeneous and often limited by small samples, short follow-up, and methodological constraints. Successful programs depend on reliable infrastructure, integration with electronic records, clear clinical protocols, appropriate training, and supportive legal and reimbursement frameworks, while concerns persist about data protection, medico-legal responsibility, and the potential for digital services to widen rather than narrow gaps between population groups. Overall, teledentistry should be viewed as a component of planned hybrid oral healthcare models rather than a substitute for in-person care. Future work needs pragmatic comparative studies, robust economic analyses, and equity-focused evaluations. Under these conditions, teledentistry has the potential to contribute meaningfully to more accessible, continuous, and person-centered oral healthcare.
