Many people do not want to eat onions or garlic because of the bad breath that the foods create, especially when eaten raw.

But onions and garlic add a ton of flavor to your food, so you should not let terrible breath from onions stop you from enjoying your food.

Luckily, 10 solutions will help you get rid of onion breath.

What Are The Causes Of Bad Breath?

Bad breath is known as halitosis.

Bad breath is mostly caused by bad oral hygiene, but some foods can cause bad breath no matter how healthy and efficient your oral hygiene is.

The most common causes of bad breath (mixed with a lack of oral hygiene) are sulfur compounds being left in the mouth and a lack of saliva in the mouth.

Luckily, these problems are easy to fix.

The three simplest ways to get rid of bad breath are to brush your teeth twice a day, floss once a day, and brush your tongue when you are brushing your teeth.

It is also possible to fix this problem by making sure you are drinking lots of water. This will allow your mouth to produce more saliva and have better-smelling breath.

How Long Does Onion Breath Last?

Sulfur compounds are left in the mouth after eating onions, which causes bad breath.

This bad breath can go on for hours. Sometimes when people eat onions with their dinner, they wake up with terrible breath in the morning.

Fortunately for you, remedies are available at home to sort this problem out.

Some of these methods will neutralize onion breath, while some will instantly get rid of your onion breath and even make your breath smell good.

How To Neutralize Onion Breath

These methods may not make your breath smell good, but they will definitely help disappear your onion breath.

After using these methods, it will be like you never ate onions in the first place.

The following methods will neutralize your onion breath.

1. Drink Water

When you drink water, your mouth produces more saliva.

More saliva means a better-smelling breath.

When you have a meal that contains onions, make sure to drink water after your meal.

Drinking water during the meal helps too.

Drinking water washes away some of the sulfur compounds left behind in your mouth and helps create more saliva.

This method will not make your breath smell like a bundle of roses, but it will definitely help dampen the very bad breath that eating onions create.

2. Use Tongue Scrapers

Brushing your tongue with a toothbrush or using a tongue scraper with a toothbrush is one of the most overlooked methods of having good breath.

People often neglect these methods, but the tongue and the top of your mouth are likely to collect residue from your food, such as onions.

Using a tongue scraper or a toothbrush all around your mouth is a great way to prevent bad breath.

3. Eat Some Fruits Or Vegetables

Although this may not be the most effective method of getting rid of onion breath. Still, it is definitely one of the healthiest methods.

Eating fresh vegetables or fruits has been proven to combat the smell of eating onion, but it will not clean your mouth as a toothbrush would.

4. Drink Apple Cider Vinegar

This method is not scientifically or clinically proven. Still, it is one of those ‘life-hacks’ that are said to work by multiple people who have tried it.

People have claimed that if you drink a tablespoon of apple cider vinegar before or after you eat onion, you will not have onion breath after your meal.

This may or may not work, but it is definitely worth trying if you are desperate.

5. Drink Some Green Tea

Unlike apple cider vinegar, drinking green tea has actually been studied.

Green tea has been reported to improve bad breath, benefit your oral hygiene, and get rid of more plaque than some mouthwashes.

Therefore, drinking green tea after your meal will likely improve your bad breath and benefit your oral health.

6. Drink Milk Or Lemon Water

Both milk and lemon water have proved to chemically fight the sulfur left behind from onions.

So, adding a tablespoon of lemon juice to some water or drinking full-fat milk after a meal will efficiently combat the smell of onion breath.

However, it will not make your breath smell amazing. 

How To Get Rid Of Onion Breath Instantly

Sometimes we do not have the time to let the onion breath disappear on its own or the time to use the methods above.

Instead, we want quick results that will also make our breath smell nicer than it did even before you ate the onions.

These methods will get rid of your onion breath instantly and make your breath pleasant to smell.

1. Chew Gum

This one is obvious, as gum has been around for ages to improve the way your breath smells.

Chewing gum will improve the way your breath smells, but it will not clean anything in your mouth.

It is also possible that food residue may get stuck in your gum and eventually render the gum useless if you chew it for too long.

2. Brush And Floss 

This is one of the most overstated things in the oral world, but it is for a good reason.

Toothbrushes and dental floss are specifically designed to eliminate the leftover food stuck between your teeth, which causes bad breath from onions.

Suppose you brush and floss once you have had a glass of water after your meal with onion.

In that case, you are likely to remove almost all of the onion residue, resulting in a nice-smelling breath.

3. Use Mouthwash

Mouthwash was created to chemically battle things like food residue and plaque in your mouth instead of physically battling it using a toothbrush or floss.

However, many studies have shown that if you rinse your mouth with mouthwash after brushing your teeth, the mouthwash will combat the plaque and residue, leaving your mouth clean and smelling fresh.

4. Chew On Nice-Smelling Herbs

Pleasant-smelling herbal leaves like mint and parsley have been proven to combat the bad breath that eating onion creates.

However, just like eating fruits and vegetables, chewing on herbs leaves will not clean your mouth.

Nevertheless, this remedy has been used for thousands of years to combat bad breath, so it clearly works.


Nobody can stand when someone’s breath stinks of onions and when their own breath stinks of onions, either.

Luckily for all onion lovers, there is no need to sacrifice the flavor that onions give food because we are self-conscious about how our breath will smell.

There are many different solutions, both clinically proven and not-so-clinically proven.

Some will improve your oral hygiene, while some will just combat the problem at hand – bad breath.

You can now enjoy good food and be confident in how your breath smells.
