Legionella and Dentistry

A dental legionella risk assessment is not just a generic water hygiene check. Dental practices have specific risks, responsibilities and compliance requirements because of the way water is used in surgeries, dental unit waterlines, reverse osmosis systems, decontamination rooms and aerosol-generating procedures. For a busy dental practice, the aim is simple: keep patients, staff and […]

If you’ve searched for a “legionella test for dentists”, you’ve probably seen quick DIY test kits promoted as a fast, low-cost solution. They look convenient. They’re not. For UK dental practices, relying on a simple test kit can leave you non-compliant, exposed to risk, and vulnerable during a CQC inspection. Let’s break down what’s really

UK Dentists The UK performs relatively well on governance and guidance, tough recent nationwide published prevalence data is hard to find. In England, dental practices are expected to follow HTM 01-05, which includes a dedicated chapter on hot and cold water systems and dental unit water lines. The CQC’s updated 2025 guidance also makes it

While rare, this is where the real-world consequences show up. One of the most significant examples comes from paediatric dentistry: A cluster of invasive infections linked to contaminated dental waterlines Several outbreaks internationally (the US cases being the most documented) involved children who developed serious Non-Tuberculous Mycobacteria (NTM) infections after pulpotomies in clinics with heavily

Dental unit waterlines (DUWLs) are the perfect home for biofilms — microscopic communities of bacteria that cling to the inside of pipes. Because the tubing is narrow and water flow is intermittent, biofilms have exactly what they need to grow: And so, even in well-run practices, research shows waterlines can harbour: Most of these don’t

Today’s dental chairs and delivery units are precision-engineered medical devices. Inside them you’ll find: ✔ Micro-engineered waterlines Ultra-fine tubing delivers clean, controlled water to handpieces and ultrasonic scalers. This lets dentists work with millimetre accuracy, cool the tooth surface, and keep the field clear. ✔ High-tech filtration and flow systems Modern practices often use independent
