Your practice does not pause when you step away from the chair. A referring doctor calls with a question about a case. A patient has a post-op concern. Your team needs a decision, and you are at a study club three time zones away. For most practices, being out of the office has always meant being out of reach, and slower answers put referral relationships and patient confidence at risk. TDO Mobile closes that gap. It puts your practice in the palm of your hand, so the work keeps moving whether you are at the office, at home, or on the road. Review pre- and post-op radiographs and clinical images from your phone. Check your schedule, pull reports, and stay current on the day without adding to your team's workload. The tools you rely on in the office travel with you. TDO Mobile is the companion app to TDOS, The Dental Operating System, the practice management platform built for the way endodontists work. Together with TDO Cloud, it extends TDOS to every device, bringing clinical charting, scheduling, financials, reporting, and patient registration into one connected system with no paper records to chase. For more than 25 years, TDO has set the standard for endodontic clinical documentation, and TDOS carries that legacy forward as a modern, web-based platform. It remains the most widely used endodontic practice management software in the specialty and is taught in 40+ university programs worldwide. TDO Mobile brings that same depth to your pocket. TDO Mobile requires an active TDO subscription.
