How to choose your mouthwash

Here are some criteria that will help you choose the best mouthwash.

#1 - The composition

The composition of a mouthwash guarantees the action it undertakes. In a solution such as a mouthwash, a distinction is made between the active ingredient(s) - whose presence dominates the solution and gives it its properties - and the excipients, which are usually complements in taste, color, or consistency. The optimal concentration of the mouthwash thus depends on its components.

#2 - The spectrum of antimicrobial activity

The spectrum of antimicrobial activity determines the action potential of the mouthwash and its limits. Microbial activities depend on environmental conditions. Depending on the nature and strength of the bacteria, the spectrum can be narrow or broad.

#3 - Persistence

The persistence of the mouthwash is defined as its persistence over time after application: it depends on its ability to be absorbed by the various oral surfaces. Depending on whether the persistence is long-lasting or not, the mouthwash proves to be effective or not.

#4 - Bacterial resistance


any treatment in excess, the mouthwash can also lead to possible bacterial resistance. For this, it is always important to take into account the duration of use of the mouthwash and not to exceed it, otherwise it will no longer act properly.

#5 - Side effects

Sometimes mouthwash can have adverse effects on your body. Sometimes the use of other products is also contraindicated when using the mouthwash. The package insert always points out this kind of information, so take the time to read it to avoid any accidents.

What to avoid when using mouthwash

Mouthwash would be a daily must for maintaining good oral health: you will certainly tend to include it among your everyday products, which you will not be able to do without. However, you should know that excessive use of this solution can be a health risk.

Scientific studies show that using chlorhexidine mouthwash too often can lead to heart problems. Similarly, the amount of alcohol in some types of mouthwash increases the risk of cancer in the mouth, vocal cords or throat.

To avoid these pathologies directly, the main precaution is to limit the use of mouthwash to once a day. Using it three times a day over a long period of time does not mean that the effect will systematically double or triple in effectiveness.

A visit to the dentist is essential to keep your teeth healthy: he or she will be able to recommend the steps to take so that you do not repeat the same treatments year after year.

The different types of mouthwash

To determine which mouthwash would be best for you, know what different types exist.

Antiseptic mouthwash

Most of the antiseptic mouthwashes are made of chlorhexidine or hexetidine. Their main role is to treat infections or inflammation of the gums or to dissolve mouth ulcers. Basically, they prevent the bacterial spread and the formation of dental plaques.

Healing mouthwash

Healing mouthwash, whose active ingredient is usually hyaluronic acid, works effectively on bleeding gums and canker sores. The healing mouthwash also contains a fairly high dose of alcohol. Therefore, it is strictly recommended to limit its use at the risk of damaging the oral flora. In principle, the use of this type of mouthwash does not exceed a period of two weeks.

Refreshing mouthwash


can also use a mouthwash specifically dedicated to preserving the whiteness of your teeth, preventing tartar or maintaining fresh breath. For your oral comfort, opt for the refreshing mouthwash. However, be sure to determine the cause of your bad breath since sometimes a simple mouthwash is not enough to remedy it (in case of a gastric disorder for example).

The protective mouthwash


protective mouthwash reinforces through its specific formula the dental enamel to fight preventively against cavities. It is recommended for people who have fragile enamel or who wear orthodontic appliances. Some protective mouthwashes are also designed to protect the gums.

Mouthwash or natural treatment?


Mouthwash complements tooth brushing for healthy oral hygiene. It prevents various anomalies such as cavities, mouth ulcers, bad breath, bleeding gums, etc. Thus, the treatment with mouthwash is carried out by means of chemical solutions with different compositions according to their type and action. After brushing the teeth, the mouthwash provides an active reinforcement of oral hygiene: rinsing is no longer necessary after the mouthwash.

Natural treatment

Natural remedies also exist and can be substituted for mouthwash. Clove has well-recognized anaesthetic and antibacterial properties. It is infused in warm water, the resulting solution is filtered and used for rinsing after brushing the teeth. Baking soda provides almost the same results as clove on tooth enamel, but in addition it acts against tartar.


Choosing between a mouthwash and a natural treatment for oral hygiene is almost the same: however, the mouthwash has more powerful active ingredients that guarantee a rapid effectiveness on the treatment. The natural treatment, on the other hand, does not present any risk of side effects.

Why use a mouthwash?

Get fresh breath

This one is the most common. Mouthwash gives you good breath that even toothpaste can't give. However, it doesn't last long. It kills all the bacteria associated with bad breath and leaves your breath very soft, but refreshing. Their advantage is that you can get a variety of flavors. So get the flavor you like the most.

Say goodbye to particulates

It is very common these days that most people only use mouthwash after brushing their teeth. They do it to get fresher breath. However, there is something they are not aware of. It also wipes away all the loose particles that have formed in your mouth when you wake up. Try using your mouthwash before brushing your teeth and get a better brushing and flossing experience.

Prevents plaque

There are various mouthwashes on the market that can help prevent plaque growth on your gums. It can also grow in the middle of the teeth and on the surface of the teeth. Although it surely prevents the growth of plaque, it cannot stop the plaque that already exists. So be sure to brush your teeth regularly, as together they can be a cure for many oral problems.

Fights cavities caused by growth

Yes, it can also prevent the growth of cavities. This is because it contains a fluoride property that prevents your teeth from decaying and also makes your enamel stronger. Just a tip, make sure you check the back label of the mouthwash you are going to buy. This is because most mouthwashes do not contain fluoride.

Cures canker sores

Canker sores are a kind of ulcer in the mouth. With the regular use of mouthwash in your routine, you can get rid of them in a few days.


A complement, not a substitute for brushing

In order to ensure that your mouthwash has a positive effect on your oral hygiene, you must first brush your teeth regularly. Mouthwash is only an adjunct treatment to improve the effectiveness of brushing.

A treatment without rinsing


, the mouthwash is not followed by rinsing, as the water may dissolve the active ingredients that will act on the parts to be treated


A medicine, not a requirement

You are

so concerned about good oral health that you will make mouthwash a daily requirement. Think again, mouthwash is a medicine like any other, and an excess on its consumption could present risks. Normally, the use of mouthwash should not exceed two consecutive weeks.

A recommended hygiene product


taking care of your oral hygiene, mouthwash can also be used as an anti-dandruff treatment for your hair, a tonic for your face, a healing solution for small wounds, a deodorant for your armpits, a cleaning product for your bathroom and windows, and a soothing product for stings


A secret for the flowers

Mouthwash gives long life to the flowers you put in your vases. By pouring a tablespoon into it, bacteria will be eliminated and your plants will keep a good look to beautify your interior.


What is the best mouthwash?

The best mouthwash depends on your needs and your budget. Read our buying guide to find out which products are the best at the moment.

Is there an age limit for using mouthwash?

Normally, under the prescription of the dentist, the mouthwash can be used from the age of 6.

Can the use of the mouthwash expire?

Like any medicine, even if it can be kept for a long time, the mouthwash cannot be used after three years from its date of manufacture.

Would brushing not be enough: why a mouthwash?

The mouthwash is a support for brushing: the solution completes the action of the toothpaste.

Can I continue to use mouthwash after a tooth extraction?

It is even highly recommended after 24 hours, not before.
