Are you feeding contaminated water to patients?

Did you know that water that looks crystal clear may be hiding thousands of harmful bacteria, invisible to the naked eye?

The waterlines that feed dental units are the perfect environment for bacteria and biofilm to flourish, and yet many dental practices don’t do anything to treat their waterlines. The EU drinking water standard is 100 CFU/ml, but dentisan estimates that almost half of dental practices routinely feed lower quality water than this through their dental waterlines. The water that runs through these potentially contaminated waterlines goes into patients’ mouths, comes into contact with open wounds during oral surgery, and can be swallowed by patients.

Are you exposing your vulnerable patients to unnecessary risk?


How does biofilm form? 

Untreated waterlines will build up biofilm, but what does that mean? 
The term ‘biofilm’ refers to a complex community of microorganisms that adhere to each other and to surfaces. It is essentially a slimy, sticky substance formed by bacteria, fungi, algae, or other microorganisms that live in close proximity.
Biofilms of this nature can be commonly found in pipes, medical devices, and industrial equipment.

The formation of a biofilm typically occurs in several stages. Initially, free-floating microorganisms attach to a surface and begin to produce a sticky substance known as extracellular polymeric substance (EPS). This EPS acts as a protective matrix, allowing the microorganisms to adhere to the surface and form a cohesive structure.
As the biofilm develops, more microorganisms join the colony, leading to the formation of complex three-dimensional structures that are much harder to break down and fully remove. Within the biofilm colony, the microorganisms develop defence against threats, and resistance to antimicrobial agents. Microbial counts can reach ≥ 200,000 colony-forming units (CFU/ml) within 5 days after installation of new dental unit waterlines

Biofilms in dental unit waterlines form when microorganisms present in the water supply attach to the inner surfaces of the waterline tubing. The biofilm matrix protects the microorganisms, allowing them to multiply and form a resilient colony.

Over time, this biofilm can become thick and complex, providing a continuous source of microbial contamination. DUWLs should be flushed for at least two minutes at the beginning and end of the  day and after any significant period when they have not been used (for example, after  lunch breaks). In addition, they should also be flushed for at least 20–30 seconds  between patients. Section 6.85 HTM01-05

Dangers of biofilm

The presence of biofilms in dental unit waterlines can lead to several problems:

Water contamination

The biofilm acts as a reservoir for microorganisms, including bacteria, fungi, algae, protozoa, nematodes, and even pathogens in extreme cases. As water flows through the contaminated waterlines, these microorganisms can detach from the biofilm and contaminate the water supply, potentially exposing patients and staff to a host of harmful microbes. 


Impaired water quality

The biofilm itself can degrade the quality of the water. It can release substances and metabolic by-products that alter the taste, odour, and colour of the water. The presence of biofilms may also promote the growth of bacteria that produce sulphur compounds, resulting in foul-smelling water.


Risk of infection

When patients are exposed to water contaminated with pathogenic microorganisms, there is a risk of infection. Some pathogens commonly associated with dental unit waterlines include legionella, pseudomonas aeruginosa, and mycobacterium species. These microorganisms can cause respiratory infections, pneumonia, or other systemic infections, particularly in individuals with compromised immune systems.

Think your waterlines are clean? Almost half (46%) of dental practices that submitted waterline samples to dentisan had at least 1 fail 

Is that a risk you’re happy to take?

Don’t trust your eyes!
Biofilm, the microorganisms that form it, and the bacteria and pathogens that are caused by it, are all invisible to the naked eye. They can be invisible, odourless, and tasteless.

You cannot assume water that looks clear is uncontaminated, even if it also tastes and smells normal. 
So, if you cannot trust your eyes, how can you tell if your water is clean? The answer is simple, you need to conduct regular tests on the water passing through your waterlines. 
Doing this independently can be expensive, time consuming, and leave you without tangible evidence that you have clean waterlines. 
If you want to clean up your waterlines in an easy, convenient, and provable way, you need to join dentisan’s Clean Water Club!

Join the Clean Water Club: your solution to contaminated waterlines

How does it work?

Step one: Purge
Remove existing biofilm from your waterlines with Bioclear. The Bioclear solution is simple to use, requiring only a pre-measured and ready-to-use dose of liquid to be put through the waterline and left overnight. Then in the morning you can flush the system with clean water. 
Did you know that microbial counts can reach greater than or equal to 200,000 CFU/ml in just five days after installation of new dental waterlines. 
Because of how quickly biofilm can form, you should purge your waterlines once a week unless you are using a daily chemical, such as bioclear daily. 

Step two: Prevent
With biofilm effectively eliminated from your waterlines, it's time to shift your attention towards preventing its reformation. 
You can do this by using Bioclear Daily, a low-dose disinfectant designed to maintain clean waterlines without compromising the taste or odour of your water.

Step three: Monitor
Using Bioclear Daily will help you to keep biofilm out of your waterlines and therefore contaminated water out of the mouths of your patients. 

It is not only possible, but easy, to keep your waterlines clean when you become a member of the Clean Water Club. 
The Clean Water Club utilises the Bioclear system for removing biofilm from your waterlines, and then preventing it from reforming. 

The dentisan Clean Water Club is an online portal that will enable you to take control of water cleanliness and biofilm removal. The club will help you to manage, monitor, maintain, and audit the water quality in the lines servicing your dental chairs and treatment rooms.

Most importantly, the Clean Water Club will help you keep your patients safe from infection. 

It is paramount that you test your waterlines. 

The Clean Water Club makes this simple. 


As a member, you will be sent regular orders of Dip Slides, enabling you to take samples of your water. Pictures of the dip slides can then be uploaded to the Clean Water Club portal and submitted to the dentisan lab for analysis. 

The lab uses a clear PASS/FAIL system, so that there is no grey area over the cleanliness of your waterlines.  
If you pass you will receive a report attesting to the cleanliness of your waterlines. If your waterlines fail, you will be able to respond quickly to the presence of biofilm using Bioclear, and Bioclear Daily. 
The Clean Water Club works as a circular system. So if your dip slides pick up an unacceptably high level of CFU (colony forming units) in your water, you can return to the purge step and eradicate biofilm once again. 
Benefits for your practice
As well as keeping your waterlines clean and your patients and staff safe, joining the Clean Water Club offers your dental practice a wealth of benefits. 
•    Credible testing: When you get your water tested through the Clean Water Club you receive an impartial, independent pass/fail result, which attests to the cleanliness of your waterlines. The CQC also values being able to see tangible evidence of water testing. 
•    Saving money and time: The Clean Water Club’s simple system of a single-dose solution saves you time when compared with competitors that still require you to measure and mix cleaning solutions. The membership system also means that you receive up to 30% discount off the regular price of dentisan’s waterline products. 
•    Continued support: There is a team of in-house and field-based experts that offer full UK coverage who are on-hand to give you advice and guidance whenever you may need it.
Don't let biofilm compromise the integrity of your dental practice. Take control of your waterline management with the Clean Water Club. Join today and experience the benefits of reliable, clear waterlines, regulatory compliance, enhanced reputation, cost savings, expert support, and official certification. 
Act now to prioritise patient safety.
