Most dental leaders focus on risks they can see. But one of the most serious liability threats is flowing quietly through nearly every operatory. Drawing on the Anaheim and Georgia pediatric outbreaks and subsequent CDC warnings, this article explains why dental unit waterlines represent a hidden but manageable risk—for DSOs and private practices alike—and what leaders should be asking now to protect patients and the businesses they’ve built.

Dental unit waterlines (DUWLs) have been linked to serious infection-control failures in dentistry, including pediatric outbreaks caused by nontuberculous mycobacteria (NTM). Neglecting waterline maintenance can lead to severe patient harm, regulatory action, and reputational damage. This blog explores real-world case studies, the hidden risks of biofilm formation, and proven protocols for prevention—such as routine waterline treatment, verification testing, and documented remediation.
