Dentrix Running Slow on Workstations: Causes and How to Fix It

Short answer: If Dentrix is slow on one or two workstations, the cause is almost always those computers or their network connection: old hard drives, too little memory, Wi-Fi instead of a cable, or antivirus scanning Dentrix files. If it is slow on every workstation, look at the server and network: low disk space, an overloaded or ageing server, a struggling network switch, or backups and database exports running during office hours. Henry Schein One’s current requirements are the benchmark to check against.

Step 1: Work out where the slowness is

• One or two workstations slow, the rest fine: the problem is on those computers or their connection.
• Every workstation slow, all day: the server, the network, or the Dentrix database.
• Every workstation slow at certain times: something scheduled is running, such as a backup, a database export, antivirus scans or Windows updates.
• Only one module slow, such as Chart or the Document Center: note which one. It points to particular files or settings.

Common causes on workstations

Henry Schein One’s 2026 requirements call for Windows 10 or 11 workstations with at least 8 GB of memory (16 GB recommended), a 4-core processor, solid-state storage (SSD or NVMe) and a 1 Gbps network connection. Slow workstations usually miss one of those:

• A spinning hard drive instead of an SSD.
• Not enough memory, especially with imaging, a browser and email open too.
• Wi-Fi instead of a wired connection. Henry Schein One says wireless networks are used at your own risk because of interference from X-ray machines and other devices.
• Antivirus scanning Dentrix files every time they are read. Henry Schein One points to the Dentrix Resource Center for the correct exclusions.
• Network card power saving. Henry Schein One recommends disabling power management on network cards to avoid disconnects.
• Windows 10. Microsoft’s support ended in October 2025, and Henry Schein One says it will no longer support installing Dentrix on Windows 10 after June 30, 2026.

Common causes on the server and network

• Low disk space. Henry Schein One recommends more than 10 percent free space on all drives.
• An undersized or ageing server. The 2026 requirements list Windows Server 2016 to 2025, 16 GB of memory (more for over 10 workstations), a 4-core processor and SSD or NVMe storage.
• Database exports and backups during the day. Dentrix’s own backup guidance has you schedule database exports with the Server Administration Utility. If that or the backup runs during office hours, everyone feels it.
• An old or faulty network switch, or a damaged cable between the switch and the server.

How to fix it

1. Restart the slow workstation and test again before anything else.
2. Check the workstation against Henry Schein One’s current requirements, especially SSD, memory and Windows version.
3. If it is on Wi-Fi, move it to a wired connection and compare.
4. Ask IT to check antivirus exclusions against the Dentrix Resource Center and to disable network card power saving.
5. If every workstation is slow, ask IT to check server disk space, memory use and the network switch.
6. Check when database exports, backups and scans run, and move them outside office hours, keeping the export before the backup.
7. If the server or workstations are below requirements, plan replacements rather than keep patching.

Frequently asked questions

Why is Dentrix slow only in the morning?

Often because a backup, export or update runs late and overlaps opening time, or because workstations are all starting and updating at once.

Will more internet speed make Dentrix G-series faster?

Not usually. G-series runs on your local network. Internet speed matters more for Dentrix Ascend and online services.

Is our server too old?

Compare it with Henry Schein One’s current requirements. If it misses them, or its operating system is out of support, it is time to plan a replacement.
