Is it possible to rinse your mouth with hydrogen peroxide, how to dilute and rinse correctly

Hydrogen peroxide is a substance that modern people always have at hand, because it is used in medicine and in everyday life, in clinics and at home. Recently, many useful tips have appeared on the use of this drug for rinsing the mouth for the purpose of disinfection, gum treatment and teeth whitening. But any medicine has contraindications and negative effects , so first you should figure out whether it is possible to rinse your mouth with hydrogen peroxide and how it should be diluted.

Is it possible to rinse teeth and gums with hydrogen peroxide?

You can rinse your mouth with hydrogen peroxide without harm to your teeth and body, but only with a solution with a concentration of no more than 3%. When rinsing your mouth with this liquid, several effects occur simultaneously:


  • Disinfection of the oral cavity.

  • Acceleration of healing of wounds and inflamed mucous membranes.
  • Drying of the mucous membrane.
  • Enamel whitening.
  • Stopping minor bleeding.
  • Cleansing the oral cavity from crusts, scabs, remnants of blood clots after injuries and operations.

This complex effect has led to the widespread use of this product in dentistry. Dentists prescribe peroxide rinses for the following conditions:

  • Oral infections – stomatitis, candidiasis.
  • Inflammatory processes - gingivitis, periodontitis, periodontal disease.
  • Bleeding gums.
  • Presence of dark spots on the enamel.
  • The presence of bad breath is halitosis.

The product is used in the treatment of sore throat, otitis media and runny nose, as well as when lips become inflamed due to herpes. To do this, take a diluted solution, but it can only be used after consultation with the attending physician.

Step-by-step instructions for breeding

To disinfect pool water, it is better not to buy a technical solution, since it contains an admixture of salt and metals . This will slow down the decomposition of the peroxide.

The best option would be peroxide, used in medicine with a concentration of 35% to 37%. It is also the safest solution for humans.

Sometimes pool owners use a highly concentrated mixture of 60%. It is recommended to dilute it to 30% or lower. This is necessary for safe work with peroxide and to eliminate the possibility of damage to metal parts of the structure, which will lead to rust in the water.

In what and how?

A regular plastic canister is suitable for diluting a highly concentrated solution. To dilute the concentrated solution, use plain water.


To determine the amount of water for diluting 60% peroxide to 35%, you can use the following formula 1*0.6/0.35 – 1 = 0.71, where:

  • 1 – one gram of water;
  • 0.6 – peroxide 60%;
  • 0.35 – peroxide 35%;
  • 0.71 – amount of water for dilution.

This means that 1 liter of perhydrol will require 710 grams of water to make a 35% solution. The solution can only be mixed with drinking water that does not contain chlorine.

Cautions when rinsing teeth with hydrogen peroxide

To many, hydrogen peroxide seems like the most harmless antiseptic, but it has many contraindications and requires caution when used. The drug should not be used:

  • For severe bleeding gums in patients with periodontitis.
  • If there are a large number of fillings.
  • Patients with a thin layer of enamel and caries.
  • During pregnancy and lactation, due to the possible consequences of rinsing the mouth with hydrogen peroxide, not only for the mother, but also for the baby.
  • For the treatment of children under 12 years of age. Children may rinse incorrectly and swallow the product. In addition, they are more sensitive to the unpleasant taste of the drug, which may cause them to vomit.
  • During antibiotic treatment.

Hydrogen peroxide should not be taken orally. A solution with a concentration of more than 3% should not be used even for rinsing the mouth; it should be diluted.

Hydrogen peroxide must not only be used correctly, but also stored with precautions. A bottle of peroxide solution, perhydrol or hydroperite tablets - other pharmacological forms of this drug - should not be left in places accessible to children. Poisoning with this drug can be fatal. It is better to store the drug in a closed cabinet in a room where there is no strong increase in air temperature, otherwise it will lose its properties.

Factors affecting the concentration of the product

To determine the required concentration, a number of factors should be taken into account. First of all, this is the degree of pollution and the volume of the pool. For convenience, the level of pollution can be divided into 3 categories :

  • low,
  • average,
  • high.

Table of relationships between factors and concentration:

The concentration is given per 1000 liters of water.

If concentrated peroxide has been stored for 6 months, its effectiveness when used will be reduced by 10-15% compared to the last time. Therefore, calculations should be made taking into account these losses.

How to properly prepare the solution and rinse your mouth

Before you rinse your mouth with hydrogen peroxide, you need to dilute it. It is recommended to take a tablespoon of hydrogen peroxide per glass of water. The solution should not be hot, but not cold either. Rinsing begins only after thoroughly brushing your teeth and rinsing the mouth with clean water; such manipulations will prevent unwanted chemical reactions between the components of the drug and the toothpaste.

The peroxide solution should not be kept in the mouth for too long; it is recommended to carry out the procedure for no longer than 10 minutes. During this time, you should periodically spit out the liquid and put a fresh portion into your mouth. After the procedure is completed, the product is spat out so that it does not remain in the mouth or enter the digestive system.

If the rules of rinsing are violated, nausea and vomiting may occur; in severe cases, burns of the digestive organs may occur. If you feel a strong burning sensation during the procedure, especially if there are ulcers on the oral mucosa, you should stop rinsing and rinse your mouth with clean water.

Gargling for adults

It is not difficult for adults to use the medicine in the fight against sore throat. As for any other group of patients, a 0.25% solution is used.

An additional effective remedy would be to lubricate the mouth during illness. The wiping solution should be slightly higher in concentration than the rinse solution, so you need to know exactly how much peroxide you need.

15 ml of peroxide is diluted in half a glass of warm water. A cotton swab is soaked in the liquid and the oral cavity is soaked as deeply as possible. It is an effective and more effective way to combat tonsillitis.

Can peroxide be used to whiten teeth?

Hydrogen peroxide can be used to whiten tooth enamel only if there are no contraindications. To make sure that the enamel layer is strong enough and not too thin, it is better to visit a dentist and consult with him about the possibility of using this product.

The following whitening methods are known:

  • They take a mixture of hydrogen peroxide and soda, sometimes diluted with eucalyptus oil. The paste is applied to a toothbrush. After brushing your teeth, you need to rinse your mouth. Food can be taken no earlier than 20 minutes after the procedure.
  • Three drops of the product are placed on toothpaste; it is recommended to use toothpaste for the treatment of periodontal disease.
  • If there is a limited stain on the enamel, you can clean it with a cotton swab dipped in hydrogen peroxide. But first you need to undergo an examination by a dentist so as not to provoke the destruction of the enamel.
  • Instead of a pharmaceutical 3% solution, sometimes they take hydroperite tablets and dissolve them in clean water: 2 tablets per 100 ml.


Teeth before and after whitening with hydrogen peroxide

Is it necessary to dilute?


To disinfect a swimming pool, peroxide should only be used in a diluted state. Concentrations of 60% and above are explosive .
If dirt gets into the container, it will trigger a chain reaction of decomposition into oxygen and water, followed by heating.

The temperature will rise up to 1000°. The water will immediately turn into a gaseous state, which will be 7000 times its previous volume. Therefore, the lower the concentration of the solution, the safer it is to work with it .

If peroxide is not diluted or a high concentration is used, during bathing the undecomposed reagent will enter the mouth, stomach, eyes or nasopharynx. This will lead to disruption of the immune system.

In a child, this can cause exacerbation of chronic diseases, as well as disorders of the gastrointestinal tract. However, if you use a weak solution, it will be useless to fight bacteria. This will also lead to the global development of pathogens.

Rinsing your mouth with hydrogen peroxide to remove odor

Halitosis can be caused by many dental and internal diseases. Hydrogen peroxide helps get rid of unpleasant odor if the cause of its occurrence is related to the condition of the oral cavity. Rinsing the mouth with this product for gumboils, periodontal disease, stomatitis, and gingivitis helps eliminate pathogenic microflora from the surface of the oral mucosa. And along with it, the smell, which is a consequence of the vital activity of microbes, disappears.

If the cause of halitosis is diseases of the internal organs, hydrogen peroxide will not be able to effectively combat oral odor. Disturbances in the functioning of the kidneys and liver, diabetes mellitus provoke the appearance of various foreign odors from the mouth, even with an admixture of chemicals: acetone, ammonia. They also cannot be eliminated by rinsing; targeted complex treatment is necessary.

In case of dysbacteriosis or infectious inflammation of the ENT organs, which also cause a putrid odor in the mouth, peroxide, when used correctly, can reduce the intensity of the amber.

To rinse your mouth, hydrogen peroxide must be diluted with water (pre-boiled). You need to rinse your teeth and gums for a minute 1-3 times in a row, after which the mouth is rinsed with clean water. The procedures are done three times a day for 3–5 days.

Frequency of application of disinfection solution

To determine how often to disinfect your pool, you should pay attention to the weather .

For example, if there are many sunny days in a month and the weather is hot, in this case the treatment is carried out 2 times a month. At a temperature of 25C° and a moderate number of sunny days, the frequency can be reduced to 1 time.

It is also worth considering the contamination of the pool. There is no need to wait until it becomes too cloudy.

To determine the degree of contamination, you can take water into a transparent glass container and compare it with clean drinking water . If there is a yellowish tint and an unpleasant odor, it is time to disinfect.

Use of the product during pregnancy

During pregnancy, it can be used as prescribed by a doctor. Since this drug does not have many side effects and does not have a negative effect on the fetus.

But during pregnancy, rinsing alone is not enough, since a viral or bacterial disease can be dangerous for the child. Therefore, rinsing is often combined with other methods of treatment:

  • antibacterial therapy (antibiotics are selected taking into account the woman’s position);
  • throat sprays (Miramistin);
  • rinsing with a decoction of medicinal plants.

Despite the large number of modern medications, hydrogen peroxide is considered one of the most effective and safe drugs.

The minimal number of side effects makes it the most preferred treatment option for children and pregnant women. In addition, the main advantage is the low price of the drug.

How to treat a throat with peroxide according to Neumyvakin

Professor Neumyvakin introduced many methods of drug treatment into practice.

Rinse according to Neumyvakin:

  • 1-2 teaspoons of peroxide;
  • ¼ cup boiled water.

Everything needs to be mixed and then gargled. During the rinsing process, you need to retain the solution in the tonsil area.

In addition to gargling, Neumyvakin, other methods of treatment were invented. For example, treatment of skin diseases or diseases of the mouth and gums.

Side effects of peroxide and contraindications for use

The solution is considered the safest drug, which is indicated even during pregnancy. Usually no unpleasant symptoms occur and they occur very rarely, but still. Forewarned is forearmed.

But it also has side effects:

  • irritation of the mucous membrane;
  • allergic reactions;
  • irritation of the mucous membrane of the esophagus or stomach (if accidentally swallowed).

Contraindications for rinsing are:

  • children under 3 years of age;
  • allergic reactions to the drug.

What to do after rinsing

After gargling, be sure to irrigate your throat with plain boiled water at room temperature or a decoction of medicinal plants. This is necessary to soften the mucous membrane of the pharynx, as well as to remove residual peroxide.

You can use solutions of sea or table salt.

It is also not recommended to refrain from eating and drinking liquids for 1 hour after rinsing.
