I recommend you use it morning and night after brushing your teeth.

What could be better

While TheraBreath Oral Rinse doesn’t have any artificial flavors or colors, it leaves your mouth with a taste after use. I guess that is due to its patented formula. It may take a few days for your mouth to adjust to this taste.

While this doesn’t affect the quality of the mouthwash, it’ll be nice to see TheraBreath reduce the taste a bit.

CloSYS Original Unflavored Mouthwash

CloSYS Mouthwash

CloSYS doesn’t contain any flavors and alcohol. The American Dental Association accepts it.

The mouthwash doesn’t burn in your mouth like most others you’ll find out there. In fact, it’s made for sensitive mouths. It works gently and effectively.

CloSYS Original Unflavored Mouthwash kills 99% of germs and bacteria in your mouth. That’s possible because CloSYS contains Choralstan, a patented ingredient that kills 99.9% of the bacteria that cause bad breath and reduce harmful bacteria in your mouth.

Don’t eat and drink after 20 – 30 minutes of brushing your teeth and using this mouthwash. This allows CloSYS to balance your mouth’s pH.

Eating or drinking during this time will disrupt and end the process, thereby making the mouthwash less effective.

My Impression

Thousands of dentists in the United States recommend CloSYS mouthwash to their patients. Apart from bad breath, they also prescribe it for mouth sores and even for cancer patients who are undergoing chemotherapy treatment.

This mouthwash doesn’t burn or irritate sensitive mouths. It kills bacteria in 10 seconds. So, if you’ve got a sensitive mouth, you have nothing to worry about using CloSYS Original Unflavored Mouthwash.

CloSYS is the best mouthwash for bad breath. This mouthwash leaves your mouth feeling clean and fresh after use.

What could be better

Even though CloSYS unflavored mouthwash is a highly recommended oral care, it gives you an unpleasant taste right after you use it. The first 4 – 6 minutes can be very serious.

After then, your mouth taste return to normal.

It’ll be cool if CloSYS can make the mouthwash taste a little bit better after use.

Crest 3D Mouthwash

Crest 3D Mouthwash does three things:

  1. It whitens the teeth

The mouthwash isn’t too minty and still keeps your breath fresh. You have the option to return the product and get your money back in case you’re not satisfied.

Crest 3D Mouthwash is made with a unique formula that not only sets it apart from many other mouthwashes, but you also get better-quality breath and teeth.

Some users claim they’ve been using it for years and they’ve never been disappointed with the quality of the mouthwash. Those who have tried popular options out there said they quickly came back to use Crest 3D Mouthwash because its quality can’t be beaten.

Essential Oxygen Organic Brushing Rinse Mouthwash

Essential Mouthwash

The ingredients used to make this mouthwash are clean and organic. Common ingredients like alcohol, glycerin, sodium lauryl sulfate or fluoride aren’t used to make Essential Oxygen Brushing Rinse Mouthwash.

If you’re looking for the best mouthwash for bad breath that’s made with organic ingredients, you know it now.

The fact that the mouthwash is made with organic ingredients doesn’t mean that it’s less effective. This mouthwash does a great job at killing oral bacteria that build up in your mouth.

It works more like toothpaste than an oral rinse.

You’ll have to apply it to your mouth and brush your teeth with it before spitting it out. Using this mouthwash correctly is the key to getting expected results.

My Impression

As I noted above, brushing rinse is different from oral rinse. I’ve seen many people complain that this mouthwash isn’t working for them. It turns out that they weren’t using it right.

One key thing I quickly want to note here about my impression of this mouthwash is that it almost doesn’t taste at all. Though, it still has a slight mint in it. That mint taste is so low when you compare it to other mouthwashes.

If you’re one of the very few people who hate aftertaste, I’ll say this is the best mouthwash for bad breath for you.

If you also hate using a mouthwash that contains fluoride, I strongly recommend you get Essential Oxygen Organic Mouthwash.

No doubt, your breath will be fresh for the whole day after using it.

What could be better

Note that a brushing rinse mouthwash isn’t a replacement for a normal toothpaste. You should use both together. Some people hate brushing rinse because they don’t have time to brush twice.

I’ll love Essential Oxygen to create an organic rinsing mouthwash version of this. While the fact that it’s organic is cool to some customers, it doesn’t mean they like using a brushing mouthwash.

Smart Mouth Mouthwash

SmartMouth Mouthwash

When you use SmartMouth Mouthwash, you’ll be able to open your mouth without shame. You’ll be able to speak and smile more.

My Impression

After trying SmartMouth Mouthwash, you won’t be able to live without it because its performance will exceed your expectation. Its works great for people who smoke too.

The packaging of this mouthwash is very unique. I guess they’ve done this to separate the brand from competitors.

This is a mouthwash that works well and sells at a great price. It’s affordable. When you compare this mouthwash to others that aren’t even as effective as it is, you’ll agree that you’re getting the value for your money.

With this mouthwash, you can say goodbye to bad breath.

What could be better

While the product itself is highly effective for eliminating bad breath, the pour design is poor. It’ll be cool if they can improve the design to be better for pouring.

It makes no sense to have a good product, only for the packaging to prevent people from buying it.

Listerine Antiseptic Mouthwash

Listerine Antiseptic Mouthwash

Listerine Mouthwash kills germs and bacteria that cause bad breath and gum disease. According to the Listerine brand, the mouthwash cleans 100% of your mouth and kills 99% of germs.

The mouthwash gives you a healthier mouth. It ensures that your teeth, tongue, and gum are all well cleaned each time you use it.

When they are too many germs and bacteria in your mouth, it starts to smell bad.

Because you eat and drink, there’s no way germs and bacteria won’t be in your mouth. However, using a mouthwash like Listerine twice daily will kill those germs and bacteria, and give you the perfect fresh breath you want.

Listerine is a very popular mouthwash product in the world. In fact, this mouthwash was first introduced in 1914 – that’s more than a century ago.

My Impression

You can make your mouth clean and fresh again with Listerine mouthwash. There’s no doubt that Listerine is one of the most talked about mouthwashes, which is why I include it here.

Just 30 seconds of swishing twice a day are all you need to kill germs and bacteria in your mouth. When you use Listerine mouthwash twice a day, you can be sure that you have around the clock protection against bad breath, germs, and bacteria in your mouth.

Listerine has received the American Dental Association (ADA) Seal of Acceptance for fighting bad breath, plaque, and gum disease. The mouthwash doesn’t contain fluoride.

What could be better

Listerine has to change the cap of its packaging. Currently, you either have to break it or use a knife to open it before you can use it.

The product itself is excellent. It gets the job done, but they have to invest more in a better cap design.

Oxyfresh Lemon Mint Mouthwash

Oxyfresh Mouthwash

Oxyfresh Lemon Mint Mouthwash is a one-minute rinsing solution for bad breath that lasts all day.

The formula used to make Oxyfresh mouthwash is patented. The aftertaste of the mouthwash is unique. It gives you a fresh taste you won’t get in other mouthwashes.

What could be better

While the taste of Oxyfresh mouthwash is cool, I’ll say that they can make it even better. It’ll be better if they add a little bit of flavor to it. They can decide to change the flavor if they want.

Oxyfresh mouthwash still remains one of the best mouthwash for bad breath.

The Things You Should Consider When Buying a Mouthwash for Bad Breath

There are hundreds of mouthwashes out there that claim that they are the best. The truth is that very few deliver the type of quality you want.

So, what are the things you should look for in a mouthwash before you buy?

Below are five important things to look for.

ADA Seal of Acceptance

American Dentist Association (ADA) Seal of Acceptance is a program that began in 1931. Today, dentists and consumers consider it as gold.

If a mouthwash has the ADA Seal of Acceptance, it shows that it’s a high-quality product.

Before buying a mouthwash, you should check to see if it’s ADA accepted. If it’s not, simply move on.

The great thing is that I’ve done most of the work for you. The mouthwashes listed above are ADA accepted.

Its formula is patented

Many mouthwashes have nothing unique about them. Some manufacturers outrightly copied their competitors. Some are mass produced in China and shipped to the United States and Europe.

You want to be sure that you’re buying an original mouthwash.

Every original mouthwash has its own unique formula. A mouthwash with its own patented formula can never taste like any other you’ve used or came across before.

A company should take it’s time to research and test its formula in a lab and see if it works. Manufacturers that do that invest in product development. And they do that to come up with a unique product that beats their competitors.

So, before you buy, check to see if the formula is patented. If it is, it shows that the manufacturer has invested money and time into developing it and the mouthwash has been tested and proven to work.

Burning sensation or irritation in the mouth

If a mouthwash leaves you with a burning sensation for weeks or months, it means you can’t continue using it. Using it when it constantly leaves your mouth with irritation may cause more harm than good.

It’s normal to feel some burning sensation after switching to a new mouthwash. But, it shouldn’t last for more than a few days or weeks.

As time goes on, your teeth, tongue, teeth – your whole mouth gets used to the new formula.

But when a mouthwash gives you a burning sensation for up to four weeks, it’s a clear sign that it isn’t for you.

Some manufacturers may write on the label that the mouthwash causes some burning sensation. If that’s there, you may want to use a product that doesn’t irritate your mouth constantly.

It prevents bad breath

The reason why you’re buying a mouthwash in the first place is that you want cleaner and fresher breath.

If it’s not written on the label that it prevents bad breath, don’t buy it.

Some merchants may write that it’s good for oral care, but is it made for bad breath?

A mouthwash that takes care of bad breath kills 99% of germs and bacteria in your mouth.

If the mouthwash doesn’t kill 99% of germs and bacteria that are present in your mouth when you use it, then it isn’t a mouthwash for bad breath.

The mouthwash should be alcohol-free

There are two main types of mouthwashes:

  1. Alcohol-based mouthwash
  2. Alcohol-free mouthwash

Alcohol-based mouthwashes are made with alcohol. Alcohol is the main ingredient in the mouthwash.

Alcohol-free mouthwashes are free of alcohol.

Alcohol-based mouthwashes unnecessarily dry your mouth.

Here comes the main reason you shouldn’t use them:

Alcohol-based mouthwashes kill both bad and good bacteria in your mouth. Your body needs good bacteria too.

So, you lose the good bacteria your mouth needs when you use an alcohol-based mouthwash.

Check the ingredients list of the mouthwash you’re buying and see if alcohol is on the list. If it is, don’t buy the mouthwash.

The Top Ingredients in Mouthwashes That Kill Bad Breath

What are the ingredients in most mouthwashes that kill bad breath?

If you know these ingredients, you’ll search for them on the mouthwash’s label to see if it has it.

The trick is that you want to ensure that the mouthwash you’re buying has many ingredients that kill bad breath.

The more these ingredients are present, the better and more effective we can say the mouthwash is. So, what are these ingredients?

Here are the top ten ingredients you should look for:

  1. Peppermint oil: It is valued for its cooling effects. Relieves muscles and displays antimicrobial properties, which is why it can be used to fight infections and even freshen your breath.
  2. Water: A better alternative to alcohol. It flushes out toxins from your mouth.
  3. Lemon oil: It has antibacterial and antifungal properties. It works as a natural remedy for oral conditions like bad breath. It can also be used to whiten the teeth and prevent tooth decay.
  4. Zinc: It is used to speed up wound healing in the mouth.
  5. Aloe Vera: It has antioxidant and antibacterial properties. It prevents tooth decay and healthy gum. It treats canker sores.

Can mouthwash replace flossing?

I think this review won’t be complete if I don’t take the time to answer this common question I often receive.

The answer to the above question is “no.”

Flossing and using a mouthwash are different from each other. But it will be good to add both to your dental hygiene routine.

I know that flossing can be awkward and time-consuming, which is the reason why most people want to avoid it and use mouthwash instead.

They both promote better oral health. Both shouldn’t take more than 6 minutes maximum. Giving your dental health 6 – 10 minutes a day when you add both morning and evening together isn’t a bad thing. Note that you only have to floss once in a day.

Brushing your teeth and using mouthwash should be done twice a day.

Be willing to do everything you can to maintain good dental health. Bad dental health could cost you thousands of dollars. So, 10 – 12 minutes a day dedicated to your dental health isn’t that much when you compare it to the cost of having poor dental health.


I want you to have great dental health. That is why I’ve taken my time to write such a comprehensive and informative review about seven great mouthwashes and more points to address any issues you may have.

If you’re looking for the best mouthwash for bad breath, I believe that you now have some great mouthwashes to choose from.

Don’t hesitate to buy one of these mouthwashes today.
