The dental profession is slow at adopting the use of virtual health technologies as a capability to triage, screen, and monitor. Dentist to dentist consults routinely occur in both a civilian and military dental practice via email and phone consults.

Real-time encounters create opportunities to evaluate a patient at a remote location when a dentist is not physically present. Advance development of virtual health technologies to include teledentistry expands the potential utilization of tele-triage, tele-screening, tele-consult, and tele-monitoring.
