What a dental practice in Illinois is worth

Dental practices typically sell for 4.5x-8x EBITDA, or 2.5x-5x SDE for smaller owner-operated dental practices, with most deals in the $500K - $5M range. These are industry-wide benchmarks, reviewed July 2026, not an appraisal of your practice.

What buyers pay more for

A note on ownership rules: Many states limit who can own a dental practice, so sales to non-dentist buyers are commonly structured through a management services organization (MSO). The rules vary by state; confirm what applies to your practice with your own healthcare counsel.

Valuation multiples are DealSeam's industry benchmarks, reviewed July 2026. Establishment counts are from the U.S. Census Bureau, County Business Patterns 2023 (NAICS 621210). Platform ownership comes from each platform's own or press sources, verified July 27, 2026. Companies listed as already owned come from DealSeam's own research: the owner's website, the company's own website, a domain redirect, or a source found in our September 2026 ownership screen, each re-checked before publishing. Named acquisitions are the deals we have recorded from public announcements, each linked to its source; they are not every deal in the state. Ownership in this sector changes often.
