Smarter Orthodontic Care Between Visits

How Drs. Sellke, Rhee, and Nagy Use DentalMonitoring to Keep Treatment Moving

Orthodontic treatment works best when progress is monitored consistently,not just during scheduled appointments. That’s why Drs. Sellke,  Rhee, and Nagy integrate DentalMonitoring into the care of every patient.

With DentalMonitoring, patients use a smartphone app and a small scanning attachment to send quick weekly scans of their teeth. These scans allow our doctors to review your progress in detail between visits, ensuring your treatment stays on track and adjustments are made at the right time.

Why this technology is part of our treatment approach:

Closer clinical oversight

Your orthodontists can review progress regularly instead of waiting weeks between visits.

Made my daughter feel comfortable. Increased my anxiety on talk about removing her permanent teeth for braces in 1 -2 years, however. I'm hopeful this isn't the only option. Thank you
