Dental AI: What's Real and What's Marketing

Where AI genuinely helps

Caries detection

AI tools analyse bitewing x-rays and flag potential cavities with accuracy approaching experienced dentists. Best used as a second opinion, not a replacement.

Periodontal bone loss measurement

Automated annotation of bone level on x-rays — consistent and reliable for tracking changes over time.

Orthodontic treatment planning

ClinCheck (Invisalign's planning software) increasingly uses AI to propose tooth movements. The final plan is still designed by the orthodontist.

Scheduling and admin

Real impact: AI-powered scheduling, reminder systems, and patient communication. Not clinical care but measurable efficiency gains.

Where AI is emerging but not yet reliable

Oral cancer screening

Early tools exist but not yet reliable enough for independent diagnosis. Always combine with clinical exam.

Shade matching

Tools photograph teeth and suggest ceramic shades. Often acceptable for molars; still often needs human refinement for front teeth.

Risk assessment

Cavity and periodontal disease risk models improving but not yet dramatically better than clinician assessment.

Where AI is mostly marketing

"AI-powered diagnosis"

When used as a buzzword for basic software, often means nothing meaningful.

"AI-optimised treatment plans"

Software assisting with design isn't the same as AI creating treatment plans. Marketing is often overblown.

"AI smile design"

Existing digital smile design software isn't fundamentally AI-driven. The "AI" claim is often marketing polish on existing tools.

What to ask a clinic

• "What specific AI tools do you use?"
• "What does it do that a dentist wouldn't do alone?"
• "Who makes the final call on any AI suggestion?"

Good clinics use AI as a second eye, not a replacement.

The future (2027–2030)

• Real-time caries detection in the mouth with intraoral cameras
• Automated 3D implant planning from CBCT
• Chatbot-based triage for after-hours patient questions
• Personalised oral cancer risk models based on full medical history

None of this replaces the clinical relationship.

Trust but verify

A dentist who blindly follows AI outputs is as problematic as one who ignores them. The best approach:

• AI flags potential issues
• Clinician examines, correlates with exam, makes final call
• Patient is informed of both
