Dental caries causes significant physiological, financial, and social burden. It negatively affects the quality of life and healthcare economics. Many factors contributed to the creation of this burden. Amongst the most significant is the lack of efficient early caries detection and access to dental care. Teledentistry is an effective approach to increase access to dental services sustainably. Additionally, teledentistry is being used extensively in dental caries detection. This review aimed to review the literature about the accuracy of caries detection through teledentistry applications compared to traditional clinical examination. Peer-reviewed literature was searched in different databases with no time limits using the keywords: “Accuracy”, “Dental caries”, “Detection”, “Diagnosis”, “Teledentistry” to explore the literature. We identified 22 relevant studies in 3 main different settings. Five studies were carried out in in-vitro settings, while six studies in dental clinics, and the remaining were carried out in public settings, mainly schools. Our review revealed that the teledentistry for caries detection has good sensitivity and specificity when compared to traditional visual dental examination. Dental caries detection could be carried out reliably through teledentistry applications. It can be noticed that there is an ascending trend in smartphone use in teledentistry applications.
