Best Mouthwash
For Bad Breath

Choosing the best mouthwash for bad breath should be pretty easy, right? Unfortunately not. There are so many mouthwashes on the market these days, all making claims to do this and that, it's almost impossible to know which claims are honest and which ones are stretching the truth!

The main cause of bad breath is bacteria living deep within the surface of the back of your tongue and throat. These are normal bacteria, and everybody in the world has them. How do you know if you have bad breath? The best way is with a bad breath tester, like this bad breath monitor from Amazon.

I have tested pretty much ALL the mouthwashes for bad breath personally and with my patients over the years, and I can tell you that there are HUGE differences between all of them. BUT, there is ONE product that stands head and shoulders above all the others, mainly because the developer of the mouthwash is a dentist AND a microbiologist!

If you want to control bad breath, the solution is actually quite easy - you just have to know which product to use.

My guide to the best
mouthwash for bad breath

In my opinion, the best mouthwash for bad breath is the TheraBreath Oral Rinse.

But there's one important thing you must know. This bad breath mouthwash is free of alcohol and sodium lauryl sulfate. That's good! But most normal toothpastes DO contain sodium lauryl sulfate.

This will inhibit the way the TheraBreath Oral rinse works. SO, if you want to use the oral rinse, I strongly recommend using the matching toothpaste as well.

Why do I recommend TheraBreath Oral rinse as the best bad breath mouthwash?

Because it works! The main cause of bad breath is bacteria living deep within the surface of the back of your tongue and throat. These are normal bacteria, and everybody in the world has them.

They break down left over proteins, and this is actually part of the digestive process. Most proteins contain sulfur compounds.

But if these bacteria start to become over-active, they begin to break down left-over proteins more rapidly. The problem of bad breath begins when these sulfur compounds are released into your breath more quickly. Several of them are responsible for bad breath. Actually, 3 of them in particular.

So what's the best way of dealing with this? Well, we can't get rid of the bacteria completely, because they belong there. They are part of our digestion. BUT we can slow down how quickly they attack proteins, we can inhibit them from multiplying, and we can neutralize any sulfur compounds that ARE produced at this new lower rate.


These bacteria have one particular strength, which is also their weakness. They don't need oxygen.

Most life on Planet Earth needs oxygen at some level to survive. But there are some bacteria that don't. This means they can live where no other bacteria can live. They are called anaerobic bacteria. So, they have an advantage.

But it's not a case of just "not needing oxygen". It's also a case of "not liking oxygen". In fact, oxygen stops them in their tracks!

So all we have to do is somehow get oxygen to the bacteria. That's the difficult bit. You see, saliva contains oxygen, and it is coating your tongue all day, so how come these bacteria can still survive?

There is not enough oxygen in saliva to make a big difference. We need to ramp up the oxygen levels at the back of your tongue and throat, to really get at those sulfur compound-producing bugs.

So if we want to control bad breath, we need some sort of chemical formulation that is safe to have in your mouth, but releases oxygen at a high level in a controlled manner.

Bad Breath

That's exactly what TheraBreath Oral Rinse does. When you gargle with TheraBreath bad breath mouthwash, it reacts with the surface of your tongue, releasing oxygen. This is strong enough to affect the bacteria that are causing the problem, and slow them down.

Also, TheraBreath Plus Oral Rinse neutralizes any low levels of sulfur compounds that are around, eliminating bad breath. These two methods of action make it the best bad breath mouthwash, in my opinion.

As I said at the top of the page, all TheraBreath products are free of sodium lauryl sulfate. This is basically a soap that is added to most toothpastes to make them froth up and "feel" more effective. But it can also irritate the lining of the mouth, triggering canker sores in some people, and aggravating conditions like dry mouth, sore tongue and geographic tongue.  So TheraBreath doesn't use it.

Sodium Lauryl Sulfate can also interfere with the working of TheraBreath products. So my recommendation is - if you want to control bad breath with TheraBreath Oral Rinse, you must also use the matching toothpaste! This will ensure that you are getting the best results.

In fact, TheraBreath is so confident that it's products will kill bad breath, they guarantee it. They offer a 100% money back guarantee if you still have bad breath after using their products. Of all the patients I have recommended TheraBreath to, no-one has told me that it didn't work. Of course, you have to use the products as directed!
