Best Mouthwash for Bad Breath Buying Guide

You need to check a lot of things before buying mouthwash for bad breath. There are many options available in the market that one tends to get confused easily. It is always recommended to go prepared for any purchase you make.

One thing we know about mouthwash is that they’re not all the same. The difference is based on its features and usefulness. Here are some valuable points that will clear all your doubts before you buy mouthwash for bad breath.

Types of Mouthwash

Mouthwashes fall into one of two categories: therapeutic or cosmetic. The usage of both types is almost the same. Cosmetic and therapeutic mouthwashes do differ when it comes to how they work and how effective they can be.

Cosmetic Mouthwash

The reason of using cosmetic mouthwash, is to control bad breath over a short period of time. This also helps on leaving behind a pleasant taste for you to enjoy throughout the day. Cosmetic mouthwashes are those that mask bad breath, rather than cure it.

These mouthwashes typically contain mint flavor and provide a pleasant flavor. Although gives off a fresh fragrance, it won’t kill the bacteria causing your bad breath in the first place. Cosmetic mouthwash cannot really be expected to provide too many benefits as far as health benefits go. To be more precise, we call a mouthwash ‘cosmetic’ if it doesn’t help in killing bacteria that cause bad breath.

Therapeutic Mouthwash

Therapeutic mouthwash has a more practical purpose. The best thing about therapeutic mouthwash is the active ingredients in its formula. These ingredients are used to control or reduce bad breath, gingivitis, plaque, and tooth decay. Among them, therapeutic mouthwashes contain Cetylpyridinium chloride, Chlorhexidine, Fluoride, Peroxide, and Essential oils. All these elements have repeatedly been proven to enhance therapeutic properties.

Active ingredients

There are plenty of mouthwashes to choose from, but some only mask bad breath. By choosing an oral rinse with the right ingredients, you can cover up embarrassing odors. Good mouthwash kills bacteria that cause bad breath, so you enjoy fresh breath all day long.

These ingredients vary by brand and product. A typical oral rinse often includes alcohol, essential oils, fluoride, sodium chloride, triclosan, cetylpyridinium chloride, and chlorhexidine.


One of the most common antibacterial and antiseptic ingredients is Fluoride. Fluoride strengthens your teeth and makes them resistant to acidic damage over time.

Stronger teeth mean less plaque build-up and fresh breath. Make fluoride part of your daily oral care routine.


Plenty of mouthwashes also have peroxide of some kind. This ingredient helps to lift small food particles and bacterial clumps off the surface of your teeth. This makes them easily rinsed out into the sink.

Peroxide basically works by settling into small perforations or indentations on the surface of your teeth and turning into a bubble.

Essential oils

Many types of mouthwash also include essential oils. This ingredient makes the mouthwash feel good and soothe your gums and tongue. Essential oils also help control plaque and gingivitis since they tend to have antiseptic or antibacterial properties. Best Mouthwash for Gingivitis you will find in this review post.

Essential oils can also occasionally provide extra flavor or texture to a given mouthwash product. It eliminates bacteria and prevents it return.

Cetylpyridinium Chloride

Cetylpyridinium Chloride is a powerful antibacterial agent. That makes it one of the most potent ingredients for eliminating bad breath as a whole.

Bad breath is caused by an excess of odor-causing bacteria hanging out in your mouth. Powerful antibacterial agents like cetylpyridinium chloride kill lots of bacteria and give you fresh breath.


An effective mouthwash contains an antibacterial agent such as alcohol to remove odor causing bacteria. Before you buy your mouthwash, be sure to read the ingredients on the back. People who are sensitive to alcohol often choose alcohol-free mouthwashes.


Not all mouthwashes have typical peppermint or spearmint flavor. Many brands of mouthwash have more exotic flavors taking after fruits.

In case of flavors, have a check on sugar content. Abundance of sugar in the mouthwash can lead to more bacteria and cavity formation. Some organic and all-natural mouthwashes don’t have any flavor at all.

There is no fixed answer when it comes to which flavor of mouthwash is best. This all depends upon personal preferences. It’s always better to make your mouthwash product something you enjoy tasting!

Tips for Using Mouthwash

Using mouthwash may have risks, but that doesn’t discredit its advantages. It will only work for you if you know which type is suitable for your oral health needs. To get the most out of your mouthwash, you should also know how to master the techniques for using it as part of your daily oral care routine. Here are some tips to remember when using mouthwash:

  • Only use the right amount of mouthwash as indicated on the label or as prescribed by your dentist.
  • Swish the rinse around your mouth thoroughly. Keep your mouth closed and teeth slightly apart as you do so.
  • Rinse your mouth according to the recommended duration on the label or as prescribed by your dentist. The usual rinse time lasts for 30 seconds.
  • Never swallow the mouthwash. Make sure to spit all of the mouthwash after you rinse. If your kid is using mouthwash, supervise him properly. Don’t let your child accidentally ingest the mouthwash.
  • Avoid eating or smoking after mouth washing for at least 30 minutes or as instructed on the mouthwash
  • Before using mouthwash, brush and floss your teeth.

Some of us may get frustrated if we don’t get results in the first month of using mouthwash. It is definitely important to be patient. Results may take up to two or three months to become noticeable.

Advantages of Mouthwash for Bad Breath

Mouthwash is an effective product in the fight against tooth decay, gingivitis, as well as the promotion of healthy teeth and gums. Here is what a good oral rinse should contain and how it benefits your overall oral health.

Rids you of bad breath

The most important benefit of using mouthwash is how effective it is at ridding you of bacteria that cause bad breath. An effective oral rinse will provide much better protection against bacteria than regular toothpaste. It is also quite effective for people with chronic bad breath problem.

Prevents plaque

Another advantage of using mouthwash regularly is the prevention against plaque and gingivitis. Due to the cetyl pyridinium, chlorhexidine, and essential oils most mouthwashes contain, regular use can help in reducing plaque over time. Not only that, mouthwash is also known to inhibit odor-causing compounds like zinc, salts, and ketone.

Reaches more of your mouth

Brushing only reaches 25 percent of the total surface area of your mouth. Mouthwash allows people to clean their whole mouth.

Protects against tooth decay

Some mouthwashes also contain such properties that prevent tooth decay. The main ingredient behind a mouthwash’s capacity to prevent tooth decay is the fluoride ions some mouthwashes contain.

Has teeth whitening properties

Some mouthwashes have teeth whitening properties as well. This is a very popular demand for many of those who buy mouthwash nowadays. Although there is nothing really wrong with using a teeth whitening mouthwash, some of the ingredients used in its making can cause allergies or other medical conditions. In general, you can begin to see clear evidence that the mouthwash is working after at least one month.

Healthy gums

Bacteria in your mouth can cause harm. Brushing does not remove bacteria, which can then be left to build up and cause irritation and inflammation of your gums. Mouthwash can help kill harmful bacteria for healthier gums. Best mouthwash for gums we have a review about as well.

Fight gum disease

With gum disease like gingivitis, gums can get inflamed or infected because of plaque from bacteria and food that lingers on teeth. In severe cases, they may bleed. An antibacterial mouthwash, like one with alcohol or chlorhexidine, may help prevent gum disease.

Strengthen enamel

Some mouthwashes contain ingredients that can strengthen enamel. This will help keep your teeth more resistant to decay.

Disadvantages of Buying a Mouthwash for Bad Breath

Rinsing with mouthwash is done in order to keep breath fresh and prevent odor causing bacteria, cavities, and plaque in the mouth. While it helps in promoting good oral health, using mouthwash can also have some downsides. Let’s have a look at them.

Tooth staining

Mouthwash can stain and darken teeth. Certain mouthwashes contain heavy dyes. When these dyes come in contact with food additives left in the mouth, they can actually stain your teeth.

Irritates canker sores

Mouthwash containing alcohol content sometimes results in irritation. If the alcohol content of your mouth rinse is too high, it may actually end up irritating the canker sore more than helping it.

Masks bad breath

Using mouthwash without brushing and flossing can lead to fresher breath, but it may be short-lived. Mouthwash will never be a substitute for tooth brushing. It can simply mask bad breath. Using mouthwash is one of the many areas of proper oral health. It can conceal problems by giving temporary fresh breath; it will not be able to address oral issues on its own.

Killing good bacteria

Good bacteria not only exist in your digestive system, but also in your mouth. This good bacteria act as a natural defence to fight germs. When you use antiseptic or antibacterial mouthwash, they kill all types of bacteria. This means they are killing both the good and bad bacteria in your mouth. This could reduce the effectiveness of your natural ability to fight germs.

Even though I brush my teeth daily, why I still have bad breath?

The odor of bad breath is caused by oral bacteria. People who have gum disease have more bad-breath problems than people without gum disease. If your gums have any redness, swelling, or bleeding on brushing and flossing then you may well have some gum disease. However, gums may not be the only area where bad breath originates due to bacteria. Other reasons can be due to some specific medical conditions.
