There are inequities in the provision of oral health care, and a large proportion of the population face challenges in accessing public dental health care options. Teledentistry (TD), a new branch of telemedicine dedicated to dentistry, is a potential approach that can be used to overcome these challenges. Therefore, the purpose of this integrative review was to collect information regarding the inclusion of the application of TD tools in the public dental health services. Five electronic databases (PubMed/Medline, Virtual Health Library, CINAHL, Scopus, and Web of Science) were searched for relevant articles if they reported on original data related to the use of TD in public dental health services. Twenty-four studies met the inclusion criteria and were, consequently, included in the review. Our key findings indicated that TD can be used for training and continuing education of professionals, for remote patient care, to exchange information among health professionals, and orientation. It increases the access to dental care and enables general practitioners to interact with specialties. The benefits include cost-effective health equity services, improve dental knowledge, and reduce consultation waiting time. However, despite the advances made with the use of this technology, there are still some obstacles to overcome, such as limited infrastructure, low levels of motivation and the lack of compliance, professional resistance, and legal and security issues. TD may be very a useful tool for dental public health increasing the quality of the care by improving access, professional education, and patient satisfaction.
