Mouthwash for Long-Lasting Fresh Breath Reviews

Crest Pro-Health Multiprotection Rinse-Clean

51tWhEp0ZbL. SL500

Crest is a well-known American oral hygiene brand that makes some of the best mouthwash available on the market. Crest Pro-Health Multiprotection Rinse-Clean mouthwash is an excellent choice for several reasons. First, this mouthwash doesn’t contain alcohol.

While that might not be a concern for some people, alcohol-free mouthwash is an essential factor for many. In addition, there’s zero burning sensation from this product, which those with mouth sores will appreciate.

It contains 0.07% cetylpyridinium chloride, which is responsible for eliminating bacteria that cause bad breath. As this ingredient is known to stain teeth, it might appear problematic. However, the amount used in this mouthwash is perfectly safe.

This product also has anti-gingivitis and anti-plaque properties. Furthermore, the Crest Pro-Health mouthwash is not acidic, so you don’t have to worry about a dry mouth or any other unpleasant sensation. However, the mouthwash doesn’t contain fluoride.

While mouthwash brands use this ionized element of fluorine as an ingredient, in the case of this specific mouthwash, Crest doesn’t. Fluoride is somewhat of a polarizing component as it’s essential for fighting tooth decay, but there are concerns around dental fluorosis and several other issues.

If you’re searching for the best mouthwash for long-lasting fresh breath without fluoride, Crest Pro-Health is an excellent choice. But what about the flavor? Crest went the traditional route with clean mint.

It’s effective but not overpowering in any way. But, overall, Crest has created a simple, effective, and affordable solution for those who want to make sure their breath stays fresh for hours.


  • Helps prevent gingivitis
  • Alcohol-free
  • Great breath freshener
  • Great value


  • Contains artificial coloring

This is a practical approach, as one bottle can stay at home, and the other can be a travel mouthwash. In terms of ingredients, this FDA-approved mouthwash is pretty impressive.

The highlight is cetylpyridinium chloride or CPC, which can help fight plaque formation. Another impressive detail is that TheraBreath Fresh Breath was formulated by dentists to fight bad breath and gum disease.

If you only use mouthwash without alcohol – you’re in luck. It’s entirely alcohol-free with zero burning sensation when used. It’s also vegan, gluten-free, and certified by Kosher Supervision of America.

It’s also the perfect mouthwash to use after you’ve had a meal with garlic or if your morning breath is particularly unpleasant. Flavor-wise, this mouthwash is all about extra mint.

It’s called icy mint, and it’s the ideal choice for people who want the most freshness from their mouthwash.

ACT Total Care Dry Soothing Mouthwash

41PQpRpIRiL. SL500

Some people avoid using mouthwash because it makes their mouth dry. But that’s often due to the mouthwash containing alcohol. Fortunately, the ACT Total Care Dry Soothing mouthwash is entirely alcohol-free.

Furthermore, this mouthwash contains xylitol which increases saliva production and generally promotes moisturization of the mouth tissue. So if you’re struggling with dry mouth, this is the mouthwash that can help in general.

Listerine Total Care Anticavity Mouthwash

41z2VjDm1fL. SL500

Listerine is a household name in the oral hygiene industry. The brand has recognizable packaging, and they take the issue of fresh breath very seriously indeed. However, this is not a mouthwash for everyone as it contains both alcohol and sodium fluoride.

The different types of Listerine mouthwash are instantly identifiable by color. In this case, the Total Care Anticavity Mouthwash is purple. So, yes, it contains artificial coloring too. However, the manufacturer highlights several essential benefits of using this mouthwash.

Due to its fluoride content, it helps prevent cavities, but there’s so much more it can do. It kills bad breath germs, strengthens enamel, and cleans the whole mouth. Most importantly, Listerine Total Care freshens your breath and keeps it that way for longer than your average mouthwash.

So much about oral health is focused on prevention, and that’s where Listerine excels. The manufacturer recommends using the mouthwash twice a day and effectively swishing each time. But what does that mean exactly?

As Listerine has antimicrobial properties, it takes about 60 seconds to kill all harmful bacteria. Hence, you’ll see the best results with Listerine if you take the time to swish properly. Despite the purple color, this mouthwash has a fresh mint flavor and a slight burning sensation due to the alcohol content.

With this Listerine mouthwash, your bad breath will likely not stand a chance. This is a true fighter against halitosis and a mouthwash brand so effective many people swear by it.

Still, it’s not everyone’s cup of tea. Regardless of its strength, Listerine mouthwash can’t replace brushing and flossing but merely complement your oral hygiene routine.


  • Cavity prevention
  • Pleasant aftertaste
  • Excellent at fighting bad breath
  • Restores enamel


  • Burning sensation

Final Verdict

It’s not easy to select the best mouthwash for long-lasting fresh breath, as the products we’ve reviewed are all exceptional. However, it’s clear that Listerine mouthwash packs a punch and is incredibly effective.

But the fact that it contains alcohol and fluoride means that it’s simply not for everyone. For those reasons, the best option is Crest Pro-Health Multiprotection Rinse-Clean mouthwash.

It’s doesn’t contain alcohol or fluoride but still prevents gingivitis and fights bad breath exceptionally well.

On top of that, it’s a great size packaging-wise, and the price tag is more than reasonable for many. Colgate is the runner-up because its whitening formula is an extra feature we all appreciate in a mouthwash.
