Teledentistry is the use of information technology and telecommunications for dental care, consultation, education, and public awareness (compare telehealth and telemedicine).
Teldentistry can also be used to assist general dentists with speciality work and improve services to underserved populations such as in rural or less developed areas.
The US Department of Defense launched a teledentristy program called Total Dental Access in 1994.
