Food That Causes Bad Breath

Food that causes bad breath

Sometimes it is very common to have halitosis or bad breath before brushing your teeth and after eating. Usually, when this happens, we do not know the cause; however, most of the time, it is caused by food that causes bad breath and that we consume without knowing its effects.

That’s right, although bad breath is commonly associated with bad hygiene habits, it can also be caused by food. Below, we will tell you some of the most consumed foods that typically cause sudden halitosis problems.

Garlic and Onion  

Garlic is often considered a good food for the body because of its benefits. Unfortunately, it is also one food that causes bad breath due to the sulfates it releases, so it is recommended to have excellent oral hygiene after consuming it.

On the other hand, onion contains sulfuric elements, which can cause halitosis problems. To this, we must add the intensity of its odor, which is usually challenging to eliminate.

Dairy Products 

One of the main problems with dairy products is that the amino acids can easily stick to the teeth and tongue, making it easier for bacteria in the mouth to get into action and transform them into sulfur, which ends up causing bad breath after consumption.


Meat is another food that causes bad breath; it is recommended to consume it in moderation to avoid halitosis. This is because, besides having amino acids that contain sulfur, it can cause other problems that worsen bad breath, such as gastritis and reflux. 


Although alcohol is usually consumed at important events and parties, excessive consumption is not recommended. This is because it can cause several health problems; one of the most common problems is dry mouth, which causes temporary halitosis.

Another thing to consider is that part of the alcohol consumed is also eliminated through the breath. 

Sugary Foods

Sweets and sugary foods are one of the leading food that causes bad breath that you should avoid because they not only cause halitosis. They are also characterized by the number of bacteria they can generate inside the mouth, which can cause other more severe problems such as tooth decay, cavities, or even gum disease.

After consuming these foods, the mouth should be rinsed with water to eliminate as much residue stuck to the teeth as possible. Water also helps to dissolve the candy that attaches to the rest of the mouth, so the saliva is cleaned and can better protect the mouth.  

Coffee and Tea

Tea and coffee are considered to be on the list of “food that causes bad breath” that you should consume in moderation, as they cause dehydration. As we explained before, dehydration inside the mouth creates a suitable environment for bacteria to do their thing and cause bad breath. 

To reduce the possibility of this happening, it is recommended to rinse the mouth in addition to moderating the consumption of these foods. Drinking water after drinking tea or coffee can help to have a more hydrated mouth, in addition to preventing the development of stains on the teeth due to the consumption of these foods.

Things you should know about these foods 

Believe it or not, it is normal for these foods to cause bad breath after being ingested, so it is recommended that their consumption is not so frequent. On the other hand, you should know that if the food that causes bad breath is consumed sporadically and you have a good oral hygiene technique, it should not affect your breath. 

However, suppose you have bad breath despite not consuming these foods or consuming them in minimal amounts and having good dental hygiene. In that case, the causes may be others that require professional diagnosis. In these cases, it is best to seek the help of a dentist to analyze your case and provide you with the appropriate services.
