Bad breath, even in modern societies, can negatively affect a person’s social life and psychology. It can also be a sign of cancer, as well as diseases of the digestive tract, respiratory tract, kidneys and sugar.

Turkey Medicals – Bad breath is an uncomfortable, unpleasant condition that leaves people in a difficult position. People who have a bad breath problem should go to the dentist and investigate the causes that can cause bad breath with it, identify the problem and find a solution. The cause of bad breath can often be the presence of a carious tooth, prostheses that are incompatible with teeth and gums, or restorations that are difficult to clean. One of the problems that often occurs today, even in civilized societies, is bad breath. So, what is bad breath, medically called halitosis, why does it occur? By its simplest definition, the presence of bad breath caused by the mouth, which is so obvious that you and those around you can hear it, can be defined as bad breath. This condition can also affect the patient’s social life and psychology.


Cavities in teeth, abscesses, gingivitis, difficult to clean, periodontal pockets and bone loss that are difficult to clean between the teeth also are among the causes of bad breath ranges. Gum pockets that cause food to accumulate around a half-buried 20-year-old tooth lead to both inflammation and bad breath. Also, bridges that are not easily cleaned and coatings that have not been renewed for many years and have a bad compatibility with the gums also cause odor due to nutrient accumulation and caries.

Prostheses that are incompatible, not cleaned, or have rough surfaces with food accumulation that need to be inserted and removed also smell due to food residues. In such cases, caries should be cleaned, gum treatment should be performed, problematic twenty-year-old teeth should be pulled out. For cleaning areas that are difficult to decontaminate, special manufactured interface brushes should be preferred. For bridge cleaning, decontamination brushes and dental floss manufactured for bridges should be used, old bridges should be renewed.

Lack of Teeth Disrupts the Intraoral Balance:

Teeth are cleaned naturally by the cheek and tongue when chewing food. But in cases where there is a lack of teeth, there is a more intense accumulation of food on the opposite and side teeth, since there will also be no chewing on the side where there is no tooth. If proper care is not taken, dense dental calculus and bacteria form in this area. This condition can also trigger bad breath. In such cases, it is necessary to eliminate the lack of teeth by implant treatment or bridge construction as soon as possible. Here are some tips that will be useful for eliminating bad breath::

The use of dental floss, underbridge floss and a brush:

Oral hygiene should be fully ensured to prevent bad breath. In addition to brushing your teeth twice a day, food residues that remain on the contacts of the teeth or escape under bridge restorations should be removed and cleaned with special ropes.

Brushing the tongue:

Language cleanliness is an issue that should not be neglected. The taste buds on the tongue are indented and protruding. The surfaces of the tongue become colored due to food and drinks consumed or cigarettes smoked. The surface of the tongue is a favorable place for bacteria to settle. For this reason, the tongue surface should also be brushed after brushing the teeth.

Use of mouthwash before going to bed:

Ensuring oral hygiene is much more important, especially before going to bed. Bacteria that live in the mouth become more active during sleep. Food residues that remain between the teeth create the ideal environment for decaying teeth during sleep. Because no food or drink enters the mouth during sleep, saliva secretion is also minimal. Before going to sleep, the teeth should be brushed, the residues left between the teeth should be cleaned with dental floss, and finally oral dec with mouthwash should be completed.

Chewing gum:

In particular, chewing gums with the addition of zinc are useful in reducing bad breath.

Chewing cloves:

Cloves, which are served after meals in restaurants, are one of the cheapest methods used to eliminate bad breath.

Consumption of yogurt:

Eating foods and drinks rich in probiotics, especially regular yogurt, is effective in reducing bad breath. It is also known that yogurt reduces the proliferation of helicobacter pylori, which is located in the stomach.

Consumption of cinnamon:

Cinnamon drinks or chewing cinnamon in the mouth are effective in fighting bacteria in the mouth.

Frequent and abundant water consumption:

Frequent and abundant consumption of water is beneficial for the kidneys, as well as reduces bad breath. Drinking plenty of water helps prevent salivary odor.

At least a mouthful of water after meals:

In cases where teeth cannot be brushed after meals, it is necessary to at least rinse the mouth with water. Rinsing with water is useful for removing food residues left in the mouth.

How not to starve:

The smell from the mouth of many people in the morning before breakfast is related to hunger. This confirms the statement ‘Starving to death’. Food and beverage consumption increases the amount of saliva and reduces bad breath.

The presence of problems with the throat, esophagus or stomach:

Those who have gastritis and reflux disease due to helicobacter pylori infection in the stomach; they may have a bad breath problem. For this reason, a gastroenterologist’s examination and treatment of stomach disorders are required to eliminate bad breath.


Smoking threatens the entire body, as well as disrupts the balance in the mouth and leads to odor. In addition, it disrupts gum health, slows down the flow of saliva, and leaves dark residues in the mouth that bacteria will easily stick to its surface. Instead of cigarettes, chew plenty of unsweetened chewing gum. Chewing sugar-free gum helps to clean your mouth by increasing your saliva secretion. Gums that use mint and similar sugary sweeteners provide short-term refreshment, but because they contain sugar, they damage the teeth. Therefore, give preference to sugar-free chewing gum.


Are there any non-oral causes that cause bad breath? If the problems in the mouth have been treated, proper oral care is being done, but the smell does not go away; different causes should be focused on and examined.

Can bad breath be a harbinger of various diseases?

Diseases of the respiratory tract, digestive system, kidneys and diabetes are the main ailments that cause bad breath outside the mouth. In patients with chronic kidney disease, there is a smell similar to the smell of fish, which is formed due to ammonia and nitrogen in the saliva. An acetone-like odor is present in diabetics; the odor increases during periods when sugar is high.

Can bad breath be a sign of cancer?

In particular, ulcers and stomach cancer can disrupt the movements of the stomach, preventing proper digestion of food. Indigestible food stays in the stomach and stinks. This smell can reach as far as the mouth. A narrowing or blockage in the intestines that can occur due to ulceration or even cancer causes food pulp to remain in the intestine and form gases. This gas tries to get out through the mouth, as it cannot get out by natural means.


The area where the bacteria that cause bad breath are most concentrated in the mouth, other than the teeth, is the surface of the tongue. On the surface of the tongue there are thin elongated protrusions that allow you to get a taste. These ledges, located between the decks that deepen in places, are very suitable for the accumulation of food residues. Especially in areas close to the throat, pits around the protrusions become deeper.

It is necessary to remember to clean the surface of the tongue during oral care. For this, it is enough to use your toothbrush or special scrapers made for the tongue. In addition, flossing and the use of mouth juices after brushing can also be effective in cleaning bacteria. Make sure that the mouth water that you use regularly does not have a medicinal property and is not dark enough to dye your teeth. Do not use it every day if it irritates your gums and mouth tissues.
