CloSYS Original Ultra Sensitive Mouthwash Review

CloSYS Mouthwash is a super gentle mouthwash that eliminates the causes of bad breath – and keeps them at bay. And it controls plaque build up and keeps your mouth naturally healthy by maintaining its pH balance.  If you want to add a mouthwash to your oral health routine and avoid harsh ingredients, CloSYS is definitely a mouthwash you should consider.

The makers of CloSYS describe the mouth as, “The Gateway to Good, Overall Health”.  And they’re right. Research clearly links poor oral health with the development of serious systemic conditions. So it’s vital to choose effective products – especially since even expert brushing only cleans 20% of mouth surfaces. But choosing the right mouthwash is not as easy as it seems….

Visit the tooth care aisle in your local store or pharmacy. The array of products making bold claims to protect your smile is overwhelming!  With shelves groaning with mouthwashes of every shade and persuasion, how do you choose one that addresses your oral health needs?

What is CloSYS Mouthwash and what is it used for?

Above all, CloSYS is an effective yet gentle mouthwash that aims to promote a healthy mouth and fresh breath. To achieve this, it targets and eliminates the causes of bad breath and the bacteria that cause plaque build up.  It also encourages the mouth to take care of itself by maintaining its natural, healthy pH balance.

What makes CloSYS Mouthwash different?

Many mouthwashes mask bad breath with strong flavors. However, CloSYS uses a unique patented formula called Cloralstan™. This technology destroys the chemical compounds that create that bad breath smell as well as killing the germs that cause oral health problems.

The active ingredient (chlorine dioxide) does not burn, alter taste or cause staining.

As testimony to their confidence that CloSYS eliminates bad breath and doesn’t just mask it, CloSYS Original Ultra Sensitive mouthwash is not flavored at all. Which brings us to the next point.

How does CloSYS mouthwash taste?

CloSYS Original Ultra Sensitive Mouthwash is unflavored and does not affect your taste buds after use. Some users say it is like using water, others notice a slightly medicinal tang but any taste that’s noted is always described as super mild.

If you like that minty kick, you have two options. You can either try the Gentle Mint flavour, or go for Flavor Control®. This is the unflavored product with the addition of a flavor dropper and natural peppermint oil. This allows you to flavor the rinse to suit your own unique taste!

But remember, the peppermint oil is concentrated and must be diluted in the mouthwash before use. Do keep it out of reach of children.

How does CloSYS Mouthwash work?

Volatile Sulfur Compounds (VSCs) are a key cause of bad breath. CloSYS uses patented Cloralstan™ technology to destroy VSCs and 99.9% of bad bacteria. It also stops them from redeveloping and helps maintain a healthy pH value in the mouth. An acid imbalance in the mouth can weaken tooth enamel, irritate gums and cause canker sores and inflammation.   

Is CloSys Mouthwash Safe?

CloSYS contains naturally activated chlorine dioxide. This chemical has been approved for use by the World Health Organization and the US Food and Drug Administration.

It has many advantage, it:

  • Keeps mouthwash stable without needing to add alcohol
  • Is effective without flavoring
  • Does not burn or alter taste.
  • Can be safely used in the long term.

This is good news, right?  The best mouthwash is the one you are happy to use all the time. CloSYS might just fit the bill for you if you hate mouthwash burn or the fact that nothing tastes right after you’ve used it!

What are the benefits of CloSYS?

  • American Dental Association (ADA) approved
  • Eliminates the causes of bad breath and prevents their redevelopment.
  • Reduces plaque and fights tartar build-up
  • Balances pH value in the mouth to keep it healthy
  • Non-Staining Formula
  • Does not burn or alter taste
  • Alcohol Free so does not dry out the mouth
  • Triclosan Free
  • Sulfate Free
  • Gluten Free

What are the cons of CloSYS?

We all respond differently to products and have different tastes and tolerances. So some users have reported:

  • Metallic taste
  • And it is more expensive than products such as Listerine

CloSYS is a great all round product if you dislike the strong, hot flavors associated with many mouthwashes. This may prevent you using a mouthwash regularly, which is important because brushing only cleans about 20% of your mouth!  It doesn’t even clean all your teeth surfaces.

CloSYS is a gentle, healthy tasteless mouth rinse that kills the bad bacteria in your mouth, reduces plaque and tartar build-up and helps to maintain a healthy oral ph balance.

So if you have a sensitive mouth or an aversion to strong, burning flavors, but want to incorporate a mouthwash into your oral hygiene routine, CloSYS is definitely worth a try.

If you try it and love it, money can be saved on multi-pack offers.

How do I use CloSYS Mouthwash?

CloSYS recommend you use their mouthwash immediately after brushing with CloSYS toothpaste.  This is because the paste and rinse combine to make the active ingredient work more effectively.

However, if you are using a fluoride toothpaste we recommend waiting for at least 2 hours after brushing.  This is to allow the fluoride in the toothpaste to continue to protect your mouth from cavities for as long as possible.

  1. Pour ½ oz (2 capfuls) into a container.
  2. Swish vigorously for between 30-60 seconds.
  3. Gargle for a few seconds.
  4. Spit out into the sink.
  5. Use twice a day.

  1. The CloSys website’s FAQ page states that the product sometimes alters the user’s sense of taste— making water taste different.

    • I have to say this has helped my canker sores and my infection much better then gargling with salt water and not so invasive.

  2. This product caused a significant change in the way foods and even plain water tastes for 5 days after using it even once. I tested this after giving the effect time to clear and was verified on a second trial. This was enough to stop me from using the product but that doesn’t mean it will for many others.

    • Hi Jeff. Thanks so much for your comment. It is always helpful for people to know the possible side effects of using oral hygiene products. As you say, we are all different but taste loss can happen after using any mouthwash, not just CloSYS. It’s sad to hear it was such a long lasting result in your case, hope things are back to normal now.

    • Yes, it appears to affect each of us differently. I find it does not have any taste effect for me. Definitely the best rinse I have ever used.

    • Sorry to hear that ! For me it is absolutely fantastic! I have had a problem with inflamed papillae and white tongue. Not only is there no change in food taste , it has helped me significantly with my problems!!! Totally recommend to everyone .

  3. I like this mouthwash as it helps with my dry mouth. But it leaves a bitter taste in my mouth and changes the taste of my foods and water. Not sure why…

  4. I am having the bitter after taste and it is not going away. What antidote do you suggest to correct this, if any. Please. I miss my tea!!

  5. Sorry to hear that ! For me it is absolutely fantastic! I have had a problem with inflamed papillae and white tongue. Not only is there no change in food taste , it has helped me significantly with my problems!!! Totally recommend to everyone .
