London, 15 July 2025 – Advent, a leading global private equity investor, today announces the sale of its stake in DONTE GROUP, Spain’s leading dental platform, to Ontario Teachers’ Pension Plan Board (“Ontario Teachers’”), a global investor with a strong track record in the dental and healthcare sectors.
Since investing in DONTE in 2019, Advent has helped to transform the business into Spain’s largest oral healthcare platform. Under Advent’s stewardship, DONTE grew from a single-brand business with 150 clinics into a diversified, multi-brand leader comprising over 400 clinics across four leading brands – Vitaldent, Maex, Moonz, and Smysecret. The company has treated around 1 million patients during this time, while investing more than €40 million in clinical quality and over €35m in technological innovation, enhancing patient experience.
Ontario Teachers’ is a global investor with over CAD$266 billion in net assets and a history of strong investments in healthcare, with a global healthcare portfolio of CAD$6 billion, including Heartland Dental, PhyNet, Veonet and NVISON. The investment underscores Ontario Teachers’ confidence in DONTE’s growth trajectory and its mission to provide outstanding patient care.
Tom Allen, Managing Director at Advent, said, “We are incredibly proud to have supported the DONTE team over the past six years in building an outstanding dental platform with a relentless focus on patient care and medical excellence.”
Gonzalo Santos, Managing Director at Advent, added, “This milestone validates DONTE’s position as a market leader in Spain and sets the stage for its continued success. We are confident that Ontario Teachers’ is the ideal partner to support DONTE in its next chapter.”
Javier Martín, CEO of DONTE GROUP, said, “We are grateful for Advent’s partnership, which has been instrumental in scaling DONTE into a leading oral health platform. We look forward to this next phase of growth with Ontario Teachers’ as we expand our presence and continue delivering cutting-edge care to our patients, and we are pleased to partner with an investor with deep expertise in the sector.”
Advent has developed significant expertise and an extensive track record investing in the healthcare sector. Over the past 30 years, Advent has completed more than 50 investments across over 15 countries in areas including pharma services, medtech, healthcare services, and life sciences. Advent is committed to partnering with healthcare businesses to scale innovation, improve patient outcomes, and deliver sustainable growth.
The transaction is subject to customary regulatory approvals and its closing is expected to take place in Q4 2025.
Advent was advised by J.P. Morgan as lead financial advisor and J&A Garrigues, S.L.P. As lead legal advisor.
