The smell of rotten eggs

The smell of rotten eggs or meat in 90% of cases is neglected periodontitis or extensive cavities.

If the dentist found no problem, to look for the answer’s standing in the office of a gastroenterologist. It is likely, unpleasant smell – a signal failure in the digestive system.

If bad breath is accompanied by heartburn, frequent sour eructation worth a visit to a gastroenterologist: for sure, the survey will identify problems of the gastrointestinal tract.

The smell of acetone

And almost always, when fasting, and the observance of low-carb diets. In the latter case, it is necessary only to reduce the consumption of protein and too fatty food, and the smell will go away.

In what diseases appears breath

Trying to self diagnose myself – a thankless task, too big for a spectrum of diseases that can Express themselves in unpleasant mouth odor.

Dental disease

This is the first thing that comes to mind to a person, once detected the problem. Indeed, the most common reason for the appearance of a sharp odor – caries. In carious cavities accumulate food debris and bacteria multiply.

A real gift for such microorganisms will be inflammation of the soft tissues of the oral cavity:

  • gingivitis;
  • periodontal disease;
  • periodontitis.

Those patients who periodically consult to the dentists for cleaning the teeth, you know that Tartar removal is always accompanied by an unpleasant odor. Rest and do not realize that accumulate in Mizuno space colonies of bacteria.

Innocuous at first glance, the plaque slowly but surely turns into Tartar, which not only causes undesirable smell, but also creates periodontal pockets. Gradually going deeper, they uncover the roots of the teeth. The teeth themselves become loose, and eventually fall out.

To avoid such a scenario, a preventive visit to the dentist should be for each patient the norm. And if there was an unpleasant smell from the mouth, to postpone the visit in the dental center should not for longer than a few days. If the doctor does not identify problems with the teeth and gums, to seek the cause of halitosis will have other specialists.


With healthy teeth and the smell of acetone breath, the physician immediately sent the patient to an endocrinologist, because that’s what usually starts to manifest itself diabetes. In this pathology the glucose is not supplied to the cells of the body, but accumulates in the blood. Cells in turn feel the energy hunger. To saturate the body rapidly breaks down fats and proteins that leads to the production of acetone.

Confirm the diagnosis can analysis of urine and blood, which will necessarily be present ketone bodies. Ignoring the smell of acetone breath can lead to hyperglycemic coma and even death.

Diseases of the liver and gallbladder

Appearance breath felt stones in the gallbladder, cholecystitis and bile stasis. Usually in this case the smell is not so strong that the patient drew attention to it. Much stronger than he is concerned about bitter unpleasant taste in the mouth, and pain in the right upper quadrant, often radiating to the back.

However, to know the “liver” just smell: it is sweet, and somewhat reminiscent of the smell of raw liver. When it becomes putrid, the body had already no longer cope with its functions, and it is likely that the patient will be diagnosed with hepatitis or cirrhosis. For the purpose of diagnosis and also conduct an ultrasound, take blood test for bilirubin and liver enzymes.

The thyroid gland

To cause unpleasant smell maybe because of irregularities in the thyroid gland. Increase or decrease of its functions is observed in 2% of the population of our planet. Disorders begin almost imperceptibly, and occur without any symptoms. One of the first warning – the smell of iodine coming out of his mouth.

Kidney disease

Suspected problems with the kidneys can be foul breath, which is clearly reminiscent of urine. In this case we can speak about the violation of protein metabolism. Metabolism is broken, and the end products of protein breakdown are ejected through the lungs. The ammonia smell is intense, although in the exhaled air and are not detected toxins.

Problems of the gastrointestinal tract

Accompanied by heartburn, belching and pain in the epigastric region sour breath almost always indicates disease, such as gastritis or stomach ulcers. It could also be bowel problems, for example, dysbiosis (microflora imbalance), which often arises on a background of reception of antibiotics and other drugs.

Pathology of the respiratory system

The putrid smell may be triggered by such diseases of the respiratory system, such as:

  • enlarged adenoids;
  • tonsillitis;
  • chronic sinusitis;
  • sore throat;
  • an inflammation of the sinuses;

  • purulent otitis;
  • inflammation of the lungs.

The odor suggests that the body is in full swing the inflammatory process, which requires urgent medical intervention.

Important! Regardless of the causes of unpleasant mouth odor, after complete cure of the disease that caused the symptom, it disappears completely. It is therefore important to determine the cause of halitosis instead of trying to mask the problem with air fresheners

Unpleasant smell in the morning

During sleep all the body’s processes, if not freeze, you are much slower than during wakefulness. This also applies to the work of the glands responsible for producing saliva. And it is this process – one of the most important factors in the fight against bad breath.

During sleep the production of saliva is much reduced. It is not enough to protect teeth and gums from harmful bacteria. In the end a few hours of sleep, the concentration of microorganisms increases several times, and their waste products create a not too pleasant smell.

In the human oral cavity is inhabited by a huge number of various bacteria. Depending on species they can cause the smell of cadaverine and hydrogen sulfide, methylmercaptan and putrescine. In other words, for the night is in your mouth gathers a whole bunch of horrific aromas that make the morning kisses, not the romantic.

Other causes of odor

In addition to the above reasons a strong breath can cause:

This diet fundamentally changes the acid-alkaline balance, and provides a favorable environment for the development of microorganisms that cause odor. To reduce its intensity by simply adding to your diet foods that contain carbohydrates.
  2. Hormonal failure. Any hormonal swings immediately reflected on the qualities of the saliva. It becomes more viscous and loses its oxygen, which in turn contributes to the appearance of the stench.
  3. Smoking. Fans of this addiction should know that the mucous in their mouth gets too dry. Followed by dryness of the mouth comes an unpleasant odor.
  4. Poor hygiene products. Incorrectly selected toothbrush or paste can also be culprits of the problem. Great choice – maneuver the brush with normal stiffness and the mobile head.
  5. Insufficient care for the oral cavity. The process of brushing should occur no less than twice a day, morning and before bedtime.
  6. Dentures, veneers, crowns, braces and even body piercing can also become promoters of bad breath. All of these items require careful care, as around them and under them constantly accumulated bacterial plaque and food debris.
Treatment of unpleasant mouth odor

Ozostomia is a serious problem that requires a comprehensive approach.

So don’t be surprised if the dentist will offer you to use several treatment methods:

  1. Scrapers. There is nothing far more effective than constant cleaning of the surface of the tongue. Ideally – after each meal. This will help to significantly reduce the number of bacteria growing in your mouth.
  2. The rinses. They deal with bacteria much more effective than chewing gum. But to feel the effect, rinse your mouth to less than 30 seconds.
  3. Toothpastes and gels. The right choice of paste or gel dentifrice is half the guarantee of getting rid of the smell.
  4. The toothpicks. Systematic use of these sticks helps to get rid of stuck in Mizuno space of food particles.
  5. Toothbrushes. Dentists worldwide recommend the use of the ultrasonic toothbrush, the bristles which can clean the most inaccessible places.
  6. Dental floss. Becoming more popular dental floss. This is an excellent tool for cleaning interdental spaces, which leaves the bacteria no chance.

All of the above methods will be effective only in one case: if the mouth has no teeth damaged by caries and gums healthy. So the first thing to do when an unpleasant odor is to undergo a full dental treatment.
