Oxford Finance, a specialty finance firm focused on healthcare services and life sciences companies worldwide, closed a $660 million senior credit facility for Specialty Dental Brands (SDB), a dental services organization focused on pediatric dentistry, orthodontics and oral surgery. Oxford acted as the sole bookrunner and administrative agent on the transaction.

Proceeds will be used to refinance the company’s existing debt and finance add-on acquisitions. Oxford initially provided SDB with a $74 million senior credit facility in September 2020.

SDB was founded in 2017 by Leon Capital Group in partnership with SDB management with the goal to create a leading network of youth-focused dental practices that provide patient care from infancy until adulthood.
