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. Learn how to protect your practice and ensure compliance with expert guidance from Agenics Labs.

Maintaining safe, compliant dental waterlines requires more than daily tablets or straws—effective biofilm control demands regular “shocking.” In this comprehensive guide from Agenics Labs, dental professionals will learn the science behind shocking dental unit waterlines (DUWLs), when and how to perform it, and why it’s critical for infection control and patient safety. Discover step-by-step procedures, expert recommendations from the CDC and ADA, and practical tips to ensure your waterlines consistently meet EPA standards (≤500 CFU/mL). From understanding EPA product claims to learning how to safely use bleach and other disinfectants, this guide equips dental teams with evidence-based best practices for waterline management. Proper shocking isn’t just compliance—it’s an essential part of patient protection and clinical excellence.
