Who’s Buying DSOs in 2026: 5 DSO-on-DSO Deals, From Heartland to Guardian
Dental consolidation in 2026 is now running through cross-border entry, mega-mergers and platform-to-platform deals rather than only solo-practice roll-ups. Becker’s Dental tracks five transactions: Dentalcorp entering the U.S. by acquiring the 21-practice Northstar Dental Partners; Guardian Dentistry Partners adding 38 locations through Select Dental Management; a three-way merger of Gen4, Modis and SGA Dental Partners under one brand; Park Dental Partners’ agreed acquisition of Village Family Dental for up to $46M; and Heartland Dental’s closed deal for the 33-practice Foundation Dental Partners. The pattern is scale-on-scale: platforms are buying other platforms.
For DSO operators and sponsors, platform-to-platform deals change both exit options and competitive density in local markets. Use the deal sizes and structures as reference points when pressure-testing integration capacity, valuation assumptions and sale timelines.

Becker’s lists five from 2026: Dentalcorp’s acquisition of 21-practice Northstar Dental Partners, Guardian Dentistry Partners’ agreement for a majority stake in 38-location Select Dental Management, the Gen4, Modis and SGA merger, Park Dental Partners’ agreement to buy Village Family Dental for up to $46M, and Heartland Dental’s closed deal for 33-practice Foundation Dental Partners.
Watch out for: This is a five-deal list, not a market count. Some deals were agreements rather than closings when Becker’s reported them, and only one has a disclosed value, stated as “up to” $46M, so the final amount may depend on terms the article does not describe. Do not infer multiples or a consolidation rate from it.
Try this: If your group could be a platform target, map which of these buyers already operate in your states and how your location count compares, then pressure-test value ranges with the HGS valuation calculator.
