Can a dentist diagnose a cavity over video?

No. A definitive cavity diagnosis requires clinical examination and X-rays. A dentist on a video call can observe visible signs of decay, assess symptoms, and determine urgency, but cannot diagnose or treat cavities remotely. Teledentistry is most useful for triage, follow-up care, and consultations where the question is 'do I need to come in?' rather than 'treat me now.'

Is teledentistry covered by insurance?

Coverage varies significantly by state and plan. Many states passed teledentistry coverage mandates during and after COVID-19. Asynchronous teledentistry is covered under some Medicaid programs as a dental triage tool. Check your specific plan's benefits or call your insurer to confirm coverage before a virtual appointment.

What about direct-to-consumer clear aligner companies — is that teledentistry?

Yes, and it's controversial. Multiple state dental boards have raised concerns about treating patients without radiographic examination, which can miss underlying disease that would be worsened by orthodontic movement. The American Dental Association recommends in-person examination before orthodontic treatment.

Teledentistry: What It Is, What It Can and Can't Do, and When It Makes Sense

May 9, 2026

What Teledentistry Actually Is

Teledentistry uses telecommunications technology to deliver dental consultation, triage, and limited care at a distance. Two main models:

Synchronous (live video): Real-time video consultation between patient and dentist. Used for triage, post-procedure follow-ups, and second opinions.
Asynchronous (store-and-forward): Patient submits photos and symptom information reviewed later by a dentist. Common in school-based dental programs and rural outreach.

What Teledentistry Can Do

Triage and urgency assessment: "Does this need to be seen today, this week, or can it wait?" — extremely useful for after-hours pain or swelling concerns.
Post-procedure monitoring: Checking healing after extraction, reviewing photos of a concern without requiring a full office visit.
Prescription management: In many states, dentists can prescribe antibiotics for dental infections via teledentistry while an in-person appointment is arranged.
Second opinions: Reviewing treatment plans and discussing options remotely.
Screening programs: School-based programs use teledentistry to identify children needing care.

What Teledentistry Cannot Do

Diagnose cavities definitively (requires X-rays)
Detect bone loss or early periodontal disease
Screen for oral cancer adequately
Perform any clinical procedure
Replace the comprehensive new patient exam

The Direct-to-Consumer Aligner Controversy

Companies that mail impression kits and aligners without requiring in-person examination have faced significant regulatory pressure. Multiple state dental boards have restricted these models on the basis that treating patients without radiographic examination can miss active decay or bone disease. In 2024–2025, several major players scaled back or exited the US market due to regulatory pressure and litigation.

The professional consensus: clear aligner treatment should begin with an in-person comprehensive exam.
