How to get rid of the smell of onions from the mouth: proven methods


In most cases, the cause of persistent bad breath is volatile sulfur compounds, which can be formed as a result of the activity of bacteria that have settled in the oral cavity. In addition, halitosis often becomes a problem for people with infectious diseases of the respiratory tract, as well as diseases of the digestive organs and liver.

In turn, experts from the Center for Hygienic Education of the Population of Rospotrebnadzor argue that the cause of halitosis can be dental diseases, poor oral hygiene, smoking, taking medications that cause dry mouth, diabetes, cancer, diet, and even ordinary stress.

Some foods can also cause temporary halitosis. These include garlic, onions, broccoli, legumes, orange juice, soda and alcohol. The fact is that after their digestion, volatile sulfur compounds also form in the body, which enter the bloodstream and quickly enough appear in the lungs and saliva. However, in this case, halitosis persists for no longer than 72 hours.


To minimize unpleasant odors after eating onions, you must:

  • cut smaller onions to avoid prolonged chewing,
  • pickle a vegetable or scald it with boiling water to remove bitterness and excessive pungency,
  • Eat meals with lots of raw onions before the main meal to break the smell of another meal.

If these techniques did not help and the question of how to get rid of the smell of onions from the mouth is still relevant, we recommend such ways to get rid of it:

Teeth cleaning

the first thing that comes to mind is to brush your teeth. Although this is the most obvious, but at the same time the most inefficient way. Toothpaste only temporarily muffles the amber. To enhance the effect, use dental floss or toothpicks to remove food debris from the spaces between the teeth, and also clean the tongue from plaque.

You can try to knock out a wedge with a wedge and “hammer” an unpleasant onion aroma with a stronger smell. Cloves, lemon balm, cardamom, mustard seeds, caraway seeds and coffee beans help. Any of the products you need to hold in your mouth, chewing gently, and spit.

The mechanism and causes of aroma

In the process of chewing onions, sulfur compounds are released that react with bacteria that are in the oral cavity. Under the influence of bacteria, onion particles begin to rot and intensify an unpleasant odor. Besides, onion particles do not break down in the stomach and are absorbed into the blood.

During gas exchange, they go outside with carbon dioxide, so it is quite difficult to mask the smell of onions or get rid of it. However, there are methods to remove bad breath.

What determines how strong the aroma will be?

Reference! The degree of intensity of bad breath depends on the amount of onion eaten and the condition of the oral cavity. In the event of a carious lesion, the smell will be stronger and more persistent.

The appearance of bad breath does not depend on the variety of onions. Green and onion equally affect the occurrence of an unpleasant problem, and also leave aroma on the hands during cooking, which contains the plant.

Recommendations for preparing a vegetable to minimize the effects

To prevent the appearance of the repulsive smell of onions from the mouth is much easier than trying to get rid of it after eating the plant. There are several effective ways to eliminate odor when preparing onions:

  1. Pouring chopped onion over boiling water does not affect the beneficial properties of the vegetable, but removes bitterness and strong smell.
  2. Use vinegar or lemon juice to make a salad that includes onions.
  3. Dress salad with olive oil.
  4. Cut the onion into small cubes - during cooking, the smell will partially disappear.
  5. Soak the plant in cold water.

These methods will make the aroma of onion less pronounced and reduce the likelihood of an unpleasant odor.

Folk remedies

  1. Milk - a high fat content and the enzymes contained in it, help to neutralize the sulfur in the onion, and therefore its smell. In addition, the product is useful for strengthening immunity and bone.
  2. Activated carbon - like any sorbent, carbon actively binds molecules that cause an unpleasant odor. It is recommended that you hold one or more tablets in your mouth for several minutes. Be careful, as coal leaves black marks on the oral mucosa, including the tongue.
