What Causes Bad Breath?

Bad breath is an embarrassing and irritating problem for many people. It can negatively affect communication between people and make social relationships more difficult. However, bad breath can usually be controlled with simple measures. The main causes of bad breath are:

Bacterial plaque and dental problems

One of the most common causes of bad breath is bacterial plaque that builds up in the mouth. Dental plaque is formed by the combination of food particles and bacteria. It accumulates on the surfaces of the teeth, around the gum line and on the back of the tongue. Plaque allows bacteria to cause cavities and gum disease and can cause bad breath.

Oral hygiene

Not practicing good oral hygiene is also one of the causes of bad breath. The amount of bacteria in the mouth should be reduced by brushing the teeth and tongue regularly, using dental floss and mouthwash. Regular dental checkups and professional dental cleanings are also important.

Feeding habits

Some foods and drinks can cause bad breath. Bad breath can occur due to the breakdown of sulfur-containing foods such as garlic and onions by the digestive system. Coffee, alcohol, and spicy foods can also make bad breath worse.

Dry mouth

Saliva is a naturally occurring defense mechanism in the mouth. With a dry mouth, saliva secretion decreases and bad breath can develop. Factors that cause dry mouth include certain medications, medical conditions, and breathing problems.

Systemic diseases

In rare cases, bad breath can be a symptom of a systemic health problem. Some systemic diseases such as diabetes, kidney disease and liver problems can cause bad breath.

Bad breath

Bad breath can come in different types, which can be caused by different factors. The different types of bad breath to be aware of include:

Morning fragrance

Bad breath can occur when you wake up in the morning or after a long period of fasting. During sleep, salivary secretion decreases and the mouth becomes dry. As a result, the chance of bacterial growth and bad breath is greater. Morning odor usually disappears with breakfast and brushing your teeth.

The smell of food

Bad breath can occur as a result of consuming certain foods. A characteristic odor can occur when sulfur-containing foods such as garlic, onions, and spicy foods are broken down by the digestive system. This smell usually goes away on its own after the food is digested.

In rare cases, bad breath can be a symptom of serious systemic conditions. For example, some diseases such as diabetes, kidney disease and liver problems can cause bad breath. In these cases, bad breath often co-occurs with other symptoms.

What causes physiological bad breath?

Bad breath

Bad breath can sometimes be caused by physiological factors. The body’s natural workings and metabolic processes can lead to bad breath in some cases. Here are some factors that cause physiological bad breath:


With prolonged fasting, the body burns fat to produce energy. This process produces substances called ketones. Ketones can accumulate in the mouth and airways, creating a characteristic odor. It smells like acetone and usually disappears after the hunger passes.

Hormonal changes

Changes in hormone levels can affect bad breath. Especially during puberty, during the menstrual cycle and during pregnancy, bad breath can differ due to hormonal changes.

Oral mucus and saliva structure

The structure of the mucous membranes in the mouth and the composition of the saliva can influence bad breath. Some people naturally have a thicker or drier oral mucosa. This can lead to bacterial buildup and bad breath. In addition, the amount and quality of saliva secretion can also have an effect on bad breath.

Sinus and breathing problems

Sinus infections, chronic nasal congestion, or other breathing problems can cause bad breath. In this case, the communication between the nose and mouth is disrupted and bad breath can increase due to bad smells emanating from the sinuses.

Tooth decay is caused by bacteria destroying tooth tissue. Bacterial buildup in caries and decay of tissues can cause a foul odor. Untreated cavities can make bad breath worse.

Oral infections

Infections in the mouth can cause bad breath. For example, mouth sores, tooth abscesses, or gum disease can cause bad breath. Such infections usually require treatment.

Problems with the digestive system
