DSO acquisition and de novo activity in May 2026 showed continued regional density building across multiple platforms. SALT Dental Partners acquired MyOrthodontist (14 locations in NC and VA) and opened two de novos. Phase 1 Equity added its 21st doctor and 31st location with a Texas practice. Apex Dental Partners expanded its Colorado presence to 12 locations, reaching 65 practices across eight states. Smile Partners USA entered Massachusetts — its seventh market — through a six-practice partnership with MFD Dental. Oral Surgery Partners, Lone Peak Dental Group, Archway Dental Partners, and USOSM also announced strategic additions, continuing the trend of regional concentration over scattered national expansion.
For DSO platform leaders and PE sponsors tracking competitive positioning, this monthly roundup surfaces which platforms are actively building regional density and which are extending into new states or verticals — the two primary organic growth levers for multi-site dental groups.
