Best Mouthwashes For Bad Breath

Mouthwash can help improve bad breath and many of the other unpleasant problems associated with having a mouth full of bacteria. However, every mouthwash is different. They all work differently and should be selected based on the type of problem you are trying to treat.

Not all mouthwashes are created equal: Some brands are packed full of chemicals and additives and actually cause more problems than they solve. Others focus mainly on aesthetics without delving much into improving your overall health. The following guide looks at the most important things you should keep in mind when selecting a bottle of mouthwash for your oral health.

How to choose the right mouthwash for you

What is the mechanism of action of mouthwashes?

Mouthwashes share a few characteristics. They’re all designed to prevent plaque buildup, and they usually have a strong mint flavor that’s meant to freshen your breath. Fluoride is the main element, just like toothpaste. This reduces the creation of acid, which protects the teeth from acid erosion caused by plaque bacteria interacting with carbohydrates in the mouth. It can also be used to strengthen or replace any enamel that has been lost. Fluoride levels in mouthwashes range from 200 to 250 parts per million (parts per million).

Additional active antibacterial or antiseptic ingredients, such as cetylpyridium chloride (CPC) and sodium bicarbonate, germicides like Triclosan, and sodium chloride, which can remove debris between the teeth and freshen breath, are found in some mouthwashes.

Should mouthwash contain alcohol?

Alcohol (particularly ethanol) is used as a carrier for the active components in several mouthwashes. The amounts are minimal, and because you don’t swallow the mouthwash, you won’t become sloshed: your breath will have a slight increase in alcohol content, but this will drop away after approximately ten minutes. Alcohol, on the other hand, can dry out your mouth, causing it to emit foul sulfur compounds that can exacerbate halitosis. Alcohol mouthwashes have also been linked to an increased risk of oral cancer in several studies, though this hasn’t been proven conclusively. You may prefer a non-alcoholic mouthwash for these reasons (or religious ones).

Gum disease or white teeth require a special mouthwash

You’ll find mouthwashes that are specifically developed to fight gum disease or whiten teeth in addition to your standard mouthwashes. Chlorohexidine or hydrogen peroxide is commonly used in the first category. This is highly efficient, however, it leaves a strong aftertaste and often a numb sensation in the mouth. Worse, if you use a strong chlorohexidine mouthwash for an extended period of time, your teeth can become discolored – albeit a “daily” mouthwash will have a lesser dose that shouldn’t create concerns.

Mouthwash: How to Use It

It’s vital to remember that mouthwash isn’t a magic dental cure-all. If you’re worried about gum disease, tooth decay, or bad breath, brushing twice a day, top and bottom, front and back, for two minutes each time is essential. When you do use mouthwash, make sure you leave it in your mouth for at least thirty seconds before washing it out. And try not to do it just after brushing your teeth, as you can be washing away the beneficial fluoride in your toothpaste.

Conclusion

The best mouthwash for bad breath will likely vary based on the individual, and it’s important to consider a wide range of elements before making your final selection. However, if we had to select one single mouthwash above all others, we would have to highly recommend TheraBreath.

This mouthwash has strong antibacterial agents and enzymes that have been shown not only to fight against the germs themselves but also their sulfur compounds (which are what actually cause bad breath). It is infused with mint and eucalyptol to fight bacteria and includes aloe vera juice and botanical extracts to soothe the gums.

It is also free of alcohol, unlike many other types of mouthwash (since alcohol tends to irritate sensitive tissues), contains no animal testing, and is formulated in a vegan manner.
