What Really Goes Wrong With IT When a DSO Buys a New Practice

A group closes on a new dental practice. Everyone’s pleased. A week later, someone goes to connect the new office and finds an eight-year-old server in a closet, a backup drive last touched in the spring, and nothing protecting the network. As far as the practice is concerned, all of that is the new owner’s problem now, starting today.

If you grow by acquisition, that scene is familiar. Dentistry is consolidating fast. According to the ADA Health Policy Institute, the share of U.S. dentists tied to a DSO more than doubled from 2015 to 2024, going from 7.2% to 16.1%.

Every one of those is a practice someone had to absorb, and the IT inside each one is where a good deal can start costing more than expected.

Key takeaways

• DSO growth is built on acquisitions, and every deal hands you an IT setup you mostly haven’t seen.
• Technical debt and all the deferred upgrades stay hidden from the outside and becomes yours at closing. For example, a CBCT is over $100,000 to replace.
• A practice on break-fix support usually can’t tell you what’s failing, since no one has been looking – and they likely won’t, unless you ask first.
• Put an IT review into every deal, next to the financial review.
• What the review turns up, you can negotiate into the price or plan for before day one.
• A thorough inspection of IT and equipment allows you to close more confidently, at the right price, and with a plan.

The technical debt you inherit

When both sides want the deal done, IT rarely gets a close look before signing. The books get reviewed and the patient list gets studied, but no one opens the server closet. So you inherit whatever the last owner spent, or didn’t spend, on technology, and you find out after the money changes hands.

Technical debt is the running cost of every upgrade skipped and every corner cut over the years. A server past warranty. A network some local tech set up and never documented. Software a few versions behind. A backup that’s never been tested with a real restore. A CBCT costs over $100,000 to replace. The practice sees patients every day and looks fine from the waiting room, so it’s easy to assume the technology behind it is fine too. The staff feel it first. They expect the new owner to have fixed everything, and instead they’re stuck on the same slow machines while a patient waits in the chair.

Break-fix support misses problems

A server that’s slowly failing gives no warning to the buyer. Backups that stopped in the spring stay quiet until someone needs a file back and it’s gone. A missing firewall shows up only when an attacker exploits it.

The seller usually isn’t hiding anything. No one was watching closely enough to catch it, because break-fix support only shows up after something breaks. You can’t plan for a problem no one has found.

Add IT due diligence to your acquisition process

The fix is to treat the IT review like the financial review: a standard step before closing. Have someone who knows what to look for walk the environment and flag what’s old, what’s exposed, and what needs attention now versus later. The earlier you do it, the more you can act on what the reviewer finds, whether that’s adjusting the offer or lining up fixes for the week you take over.

 A good pre-close review answers a few questions:

• How old are the servers and workstations, and what shape are they in?

• Do backups exist, and do they actually restore?

• What’s protecting the network edge?

• Where does patient data live?

• Are the software licenses and warranties current?

• How old and how worn is the practice’s dental equipment?

For someone who does this often, it’s quick, and it turns a guess into an actual number. Skip it, and here’s what can happen: post-acquisition, a CBCT fails and you’re on the hook for $100,000.

Find it first, and the remediation can be a condition of the sale instead of a bill you cover later. With a real number in hand, you can work the cost into the price or walk in on day one knowing exactly what you’re dealing with.

Budgeting for IT remediation before the deal closes

Even a clean review turns up a few things that need replacing right away. That’s fine when you planned for it. Groups that handle acquisitions well set aside money for those initial fixes as part of the deal, with a cushion for whatever someone else’s infrastructure throws at them. A server you planned to replace is a budget line. The same server dying in week two is a scramble that pulls your whole team off their other work and stops production.

The fixes that come up most are the basics: a server to replace, a real firewall to install, a backup that actually runs. None of them are exotic, but each one costs money and time you’d rather know about before closing than after. Standardizing makes this cheaper over time. Bringing a new office onto a stack you already run is predictable, not a custom build. Onboarding after a deal was one of the loudest complaints from DSO leaders at the 2025 Dykema conference, and the ones who’d solved it had decided early that every practice would move onto the same systems.

How IT due diligence gives DSOs a competitive edge

Done right, this is more than avoiding disasters. When your process for folding in a practice is repeatable, you can close and settle faster than buyers who reinvent it every time.

That point came up often when Ntiva’s team compared notes at the 2026 Dykema DSO Conference. In a market where good practices get several offers, a buyer who can promise a clean, fast handoff looks better to a selling dentist who still cares what happens to their staff and patients. Also, DSOs that ignore these problems end up incurring major costs associated with bad deals. The clear winners don’t let the risk of IT challenges or technical debt impact their EBITDA, they get in front of it.

That’s how Ntiva’s dental IT practice approaches acquisitions. If you have deals planned this year, the best move is a standing IT review before each one, so you know what you’re buying before it’s yours.
