When to use a mouthwash?

There are different types of mouthwash that you can use after brushing your teeth. They are recommended for people with particular gum or tooth problems. They are only really useful when the risk of cavities or gingivitis increases. You can do it in case of imperfect brushing, taking certain medications, wearing braces or bad eating habits.

Before using a mouthwash, it is important to brush your teeth with an effective toothbrush. You must first brush your teeth with a toothbrush that allows you to brush all the teeth and their faces at the same time. You can for example use the Y-Brush

What are the different mouthwash formulas?

Several mouthwash formulas are made to treat a specific problem.

Antiseptic formulas for the treatment of infections


Active ingredients such as chlorhexidine and hexetidine, which are highly dosed against germs, are found in antiseptic mouthwashes. They treat inflammation of the oral mucosa and infections. They are also recommended by the dentist after dental surgery to prevent the development of bad germs.

It helps to relieve swelling of the gums and soothe pain if there are abscesses. It should be combined with an oral antibiotic treatment for a complete healing of the infection. To avoid disturbing the balance of the oral flora, do not use the treatment for more than two weeks without medical advice.

These mouthwashes allow the reinforcement of the enamel of the teeth and make them resistant to the acids. They are mainly for people exposed to cavities. Teenagers with braces who cannot brush well can use it. These mouthwashes are used as a preventive measure and not to cure a cavity. You should use it after every meal.

Anti-aphthalmic formulas

Chlorhedixidine mouthwash may have health side effects

Designed to maintain good oral health, chlorhexidine mouthwashes help fight bacteria. They specifically address the bacteria that cause gum disease, bad breath and cavities. Nevertheless, using a mouthwash twice a day for a week could have effects on your teeth. It can cause a huge loss of diversity in the oral microbiome.

Acidification of saliva that can lead to demineralization of the teeth is an effect you can observe. In addition, chlorhexidine does not allow the bacteria to transform nitrates into nitrites. This affects the bioavailability of nitrite, which has a vasodilatory effect. However, these mouthwashes are useful, but should be used continuously and as a routine treatment. In addition, chlorhexidine will cause brown stains on the teeth because it binds to both hard and soft tissues of the teeth.

Prexidine mouthwashes also have these...

Prexidine mouthwashes cause brown discoloration of the tongue and teeth which is reversible when the treatment is stopped, especially in tea and coffee drinkers. They also generate a risk of sensitization to one of the components of the solution (parotitis, mucocutaneous irritation), requiring the treatment to be stopped, occasionally dysgeusia or burning sensation of the tongue at the beginning of the treatment. They also occasionally cause desquamation of the oral mucosa. In case of overdose, they lead to neurological accidents in children and elderly people in case of accidental oral ingestion.
