Fishy smell is heard from the mouth, causes and treatment methods

Bad breath is one of the most common complaints with which patients turn not only to the dentist, but also to other specialists (therapist, gastroenterologist, otolaryngologist), since such a problem can be a consequence of a number of diseases.

In scientific and medical circles, special terms are used to refer to bad breath, such as “halitosis” or “ozonostomia”. In ICD-10, bad breath is classified as a clinical symptom related to gastrointestinal diseases and abdominal pathologies, and is designated by code R19.6.

Putrid odor from teeth and gums can also be the result of active growth of anaerobic bacterial flora in the mouth due to infectious and inflammatory dental diseases. If a sharp, unpleasant odor appears from the gums (in the absence of other symptoms), a dental examination and oral sanitation are recommended.

If the problem does not disappear after this, a comprehensive examination of the ENT organs and digestive tract is necessary.

Why does my breath smell bad?

The mechanism of formation of bad breath is represented mainly by the growth of pathogenic flora on the mucous membranes of the gums and the inner surface of the cheeks.

The reasons for this may be different, but the basis of the pathogenetic changes is a violation of the qualitative and quantitative relationship between pathogenic bacteria (some strains of streptococci, Escherichia coli and Pseudomonas aeruginosa, the bacteria Bulleidia moorei) and aerobes that can suppress their activity.

Aerobic microorganisms are microorganisms whose ability to function is active only when exposed to atmospheric oxygen. Both microorganisms are opportunistic for humans and can cause a number of serious diseases (tuberculosis, Lyme disease, streptococcal pharyngitis, etc.), but it is their balance that allows maintaining a normal level of acidity and local immunity of the mucous membranes in the oral cavity.

A pungent odor from teeth and gums in a person who does not suffer from pancreatitis, gastritis, cholecystitis and other pathologies of the digestive system and abdominal organs occurs as a result of excessive synthesis of volatile compounds that can penetrate into the environment in significant concentrations. Such compounds are secreted by representatives of the anaerobic flora, feeding on food debris contained in dense dental plaque and deposits, therefore, one of the leading factors in the development of ozonostomy is rightly considered to be the low quality of oral hygiene.

Making your hands smell nice

If you don't know how to get rid of fishy smell on your hands, use one of the methods listed below. Buy a special liquid soap with a pronounced aroma. To eliminate unpleasant signs of your interaction with seafood, just wash your hands with it once.

You can also cut off a piece of lemon and rub it on your skin. Another option is vinegar, put a couple of spoons per liter of water and wash your hands. A useful folk remedy is ordinary beer. Rinse your hands with it, and then wash them with soap.

What could the smell be?

The cause of halitosis can be guessed by the specific odor a person emits into the environment.

Types of volatile compounds and their relationship with bad breath

Note! All the compounds listed in the table are produced primarily by pathogenic microorganisms, so dentists cite poor-quality hygienic care and dental diseases (especially chronic ones) as the main causes of unpleasant gum odor.

Types of halitosis

1. Physiological . This type of halitosis is associated with the physiological characteristics of the oral cavity and the predominantly putrefactive composition of the microflora of plaque on the back of the tongue. In this case, teeth and gums can be completely healthy.
2. Pathological . In this case, the cause of bad breath may be various inflammations in the oral cavity or diseases of the internal organs.
3. Pseudogalithosis . With this type of halitosis, there is a slight odor from the mouth, which is almost not felt by others, but bothers the patient himself. These cases are typical for people who suffered from true halitosis, successfully treated it, but continue to worry about bad breath.

Dental reasons

If a putrid odor from the gums appears suddenly, the first thing to do is consult a dentist and rule out the presence of caries, inflammatory processes in the gingival and periodontal tissues, hilar cysts and granulomas, and abscesses. It is almost impossible to independently identify the source of bad breath (gums or teeth), so dental diagnostics are carried out comprehensively and often include not only a visual examination using a medical mirror, percussion of the teeth (if periodontitis is suspected), but also an X-ray or computed tomographic examination.

The causes that can provoke halitosis include a number of pathologies and diseases.

1. Caries. This is the most common disease among all age populations, in which the hard tissues of the tooth are affected and necrotically modified. The causes of caries are dysbacteriosis, poor hygiene, lack of sufficient preventive measures, chronic infections (especially diseases of the ENT organs). A pungent odor from the gums and teeth with stage 3-4 caries appears in almost 100% of patients and is perceived by others as the smell of rotting food, feces or urine.

2. Inflammatory and infectious gum diseases. This group includes infectious and non-infectious pathologies of the oral cavity, in which soft tissues (gums and tongue) are involved in the inflammatory process. These are stomatitis, gingivitis, desquamative glossitis, pharyngomycosis of the oral cavity and other diseases whose pathogenesis is based on catarrhal, herpetic, exfoliative, traumatic or eczematous inflammation.

3. Periodontal diseases. Periodontium is a special type of fibrous collagen fibers with a low degree of elasticity that fill the space between the alveolar bone and the hilar cementum. One of the complications of periodontitis and periodontitis is the formation of periodontal (periodontal) pockets, into which food can become clogged, undergoing processes of fermentation, fermentation and decay. It is the decay products that cause the putrid odor from the gums in this case.

4. Abscesses, cysts of the gums, tooth roots or dental alveoli. Bad breath with cysts may indicate that the cavity is inflamed and filled with purulent exudate, which can be a source of hematogenous spread of infection throughout the body. Treatment for a purulent cyst or abscess is surgical (followed by antibiotic therapy).

One of the causes of bad breath can also be xerostomia, a pathology of the salivary glands, in which an insufficient amount of saliva is produced in a person’s mouth. Saliva is necessary not only to maintain normal levels of moisture and acidity, but also for the primary processing of incoming food due to the action of digestive enzymes. If there is not enough saliva, food enters the stomach poorly processed, which can cause indigestion and the release of bad-smelling gases and acids that rise up the esophagus back into the oral cavity.

Important! If the patient has undergone orthodontic treatment (dental implantation, installation of braces, etc.), in addition to a dental examination, an orthodontist consultation is also indicated to exclude galvanic syndrome - poor survival or intolerance of installed dentures.

A tooth has rotted under the crown: what to do?

If a tooth rots under the crown, then you need to keep in mind that this process is no longer reversible. It will continue until the tooth tissue on which the crown rests rots completely, after which the crown falls out (Fig. 4). Signs that the tooth is rotting are the following symptoms:

• bad smell from under the crown,
• food getting under the crown,
• root caries is visible at the lower edge of the crown,
• the tooth under the crown has turned black (if the crown is made of metal-free ceramics, then its darkening can serve as a symptom of carious damage to the tooth tissue under the crown).

Caries of the tooth root under the crown on an x-ray (Fig. 5-6) –

The best diagnosis of this process is to contact a dentist, who will be able to detect caries even on surfaces that are difficult to inspect. The onset of carious lesions on the root surface at the lower edge of the crown can be difficult to diagnose if caries occurs on the lateral surfaces of the tooth root, i.e. in the interdental space (24stoma.ru).

In the latter case, a targeted photograph of the tooth is taken (Fig. 5-6), in which caries under the crown looks like intense darkening, unusual for healthy tooth tissue. Keep in mind that early contact with the dentist in such a situation can sometimes allow the tooth to be treated and a new crown installed. Late treatment, on the contrary, brings you closer to tooth extraction.

What other reasons can cause ozonostomy?

If an examination by a dentist does not reveal any diseases or pathologies, the doctor will refer the patient to specialized specialists to determine the possible causes. These may include:

• pathologies of the digestive system and abdominal organs (pancreatitis, cholecystitis, gastritis, duodenitis, chronic colitis, irritable bowel syndrome, gastroduodenitis);
• untreated or recurrent infectious diseases of the nasopharynx and oropharynx (tonsillitis, sinusitis, laryngitis, pharyngitis);

• kidney pathologies accompanied by partial dysfunction of the renal system;
• diabetes mellitus (the smell of urine and acetone from the mouth is one of the signs of a lack of insulin);

• long-term use of certain medications that can cause xerostomia (proton pump blockers, heartburn medications, alpha-agonists, etc.);
• abuse of foods with a high content of purines and phytoncides (onions, garlic, green onions, all varieties of cabbage, sorrel);

• smoking (especially if a person smokes more than 10 cigarettes per day).

Often the unpleasant smell of sour milk or rotten eggs appears in women on diets. A prolonged absence of food in the stomach provokes increased activity of parietal cells, which are responsible for the production of hydrochloric acid. As a result, a colorless gas accumulates in the stomach, which is a compound of hydrogen and sulfur and has the characteristic smell of rotten eggs. If food does not enter the stomach, this gas rises to the top and is released into the environment through the mouth when a person talks, yawns or sneezes.

People who are susceptible to emotional instability and are often in a state of prolonged stress experience unpleasant gum odor 2.1 times more often than their peers who are in an emotionally stable state.

Important! A constant smell of rot, feces or urine from the mouth, especially if it intensifies or is combined with other symptoms (sore throat, sensation of a foreign body in the pharynx and esophagus, nausea, discomfort in the stomach, etc.), may be a manifestation of malignant tumors digestive system or larynx. Consultation with an oncologist is indicated in cases where it is not possible to get rid of the unpleasant odor within 3 months, despite a complete examination, sanitization of foci of chronic infection and adherence to personal hygiene measures.

Features of symptoms

The appearance of a fishy odor from the mouth may be periodic. A person can live for decades without even knowing about existing problems. But if the main reason for your breath smelling like rotten fish is trimethylaminuria, other symptoms may also appear. All of them are associated with the release of a stench:

• bodies;
• urine;
• vaginal discharge in women.

According to research results, children suffer from this pathology more often than adults. This is due to the transition from breastfeeding to the consumption of solid food, especially if the baby has an innate tendency to such processes. From the mouth of an adult, the smell can appear unexpectedly even for him. Signs of trimethylaminuria can appear after taking medications, as well as from a sharp increase in harmful bacteria in the intestines. This pathology is most dangerous for women. The sex hormones estrogen and progesterone contribute to the active accumulation of trimethylamine in the body. Representatives of the fairer sex have bad breath more often than men. And the signs of the disease themselves are more acute and noticeable to others.

Diagnosis at home

The patient himself very often does not notice that his breath smells bad, and the people around him are embarrassed to say so, for fear of offending a loved one. To independently assess the freshness of your breath and the intensity of odors, you can perform one of the tests below. All of them are simple to perform and do not require the help of outsiders or any special equipment or tools.

Method 1

This method requires floss (dental floss) without adding flavoring or coloring additives.

1. Clean the interdental spaces using the classic method. To assess the freshness of breath, it is necessary to treat molars (molars).
2. After the procedure, carefully examine the color of the floss. The presence of a yellowish, light brown or creamy tint indicates a large amount of bacterial plaque on the inner surface of the tooth enamel. If a pinkish tint appears on the thread, you should check the condition of your gums.
3. The smell can be assessed 20-30 seconds after the procedure.

The test cannot be considered reliable if colored or scented thread was used.

Method 2

To carry out this test, you need to use a soft silicone spoon or wooden spatula (can be purchased at a pharmacy).

Using a spatula, remove the plaque from the middle part of the tongue, then wait 10-15 seconds and evaluate the quality and intensity of the smell.

Method 3

This method is the simplest and allows you to carry out express diagnostics in 1 minute, from anywhere. To do this, wash your hands thoroughly with soap and lick the outer surface of your hand (near the thumb) or wrist. You can evaluate the result in 40-50 seconds.

Clothing and textiles without unpleasant fish odors

If you have been in contact with fish products for a long time, the issue becomes especially relevant. Clean clothes and towels, aprons and various textile items with a vinegar solution.

In such cases, care must be taken with respect to proportions so that the colored fabrics do not fade. For two liters of vinegar, a tablespoon of vinegar is enough. Soaking things in this solution lasts 2-3 hours. This is followed by a thorough rinse and normal washing.

Removing fish smell from textiles

Light-colored items can be washed in water with citric acid. It is simply added to the washing powder. Detergents are replaced with baking soda (1 glass) and the washing machine is started.

How does a dentist diagnose?

To identify signs of ozonostomy, dentists use the organoleptic diagnostic method. Indicators are measured using special instruments and analyzed in accordance with established standards.

To ensure that the test result is as reliable as possible, 12-20 hours before the doctor’s visit, the patient is recommended to:

• stop smoking and chewing gum;

• do not use hot spices, seasonings, seasonings and products containing large amounts of flavorings, flavor enhancers and dyes;

• discontinue antimicrobial treatment (48 hours before the test), if possible;

• Do not use tooth balms or rinses.

Note! You cannot brush your teeth before the procedure. The last brushing of teeth is allowed 8-10 hours before the test.

Changing your diet

If a diagnosis of trimethylaminuria is made, the patient should change his own diet. It is necessary to completely eliminate the consumption of such products as:

• eggs;
• liver;
• legumes;
• peanut;
• seafood;
• regular, Brussels sprouts and cauliflower.

Prohibited foods for trimethylaminuria

Products containing soy can also worsen your health.

Controlling your own diet will not relieve the patient from the signs of the disease, but will make them less intense and noticeable to others.

How to deal with the smell?

Treatment of halitosis and its manifestations consists of complete sanitation of infectious foci. The patient is treated for carious cavities with the installation of fillings and cleaning of the canals. If the tooth cannot be saved, extraction is prescribed (installation of dentures is permissible only after high-quality sanitation and oral hygiene). For infectious or inflammatory pathologies, a course of local treatment (application, rinsing with antiseptics, instillation), antibiotic therapy and antimicrobial therapy is carried out.

For recurrent gingivitis, the doctor may prescribe Metronidazole at a dosage of 100-200 mg 2-3 times a day. The standard course of treatment is 7-10 days. In more severe cases, antibiotics are indicated - amoxicillin, tetracycline, cephalosporin. Local applications are made with medicinal ointments and gels, some of which can be placed directly into periodontal pockets (Cholisal, Metrogil Denta, Asepta, Kamistad).

For fungal infections (candidal stomatitis, pharyngomycosis), systemic and local antimycotics are used - Fluconazole, Candide, Miconazole. In all cases, rinsing with antiseptics (Miramistin, chlorhexidine, furatsilin solution) is indicated.

Important! To treat unpleasant odor caused by diseases of the digestive system, upper and lower respiratory tract, abdominal organs, complex medical, physiotherapeutic and surgical (if necessary) treatment is prescribed: rehabilitation of foci of chronic infection in case of sinusitis, pharyngitis, treatment of gastritis, correction of IBS.

Removing fishy aroma from the apartment

It is somewhat more difficult to freshen the air in a room where fish has been fried. The most effective is long-term ventilation. If you are preparing any type of seafood by frying or baking, be sure to immediately turn on the hood.

After airing the apartment, it is recommended to freshen the air in it using special means in the form of a spray.

If you don’t have an air freshener, you can use orange zest: place it in different corners of the room. Setting the zest on fire will have an even greater effect. It produces aromatic smoke that perfectly eliminates any unpleasant odor. This method also works for removing unpleasant odors from clothes: you need to fumigate your favorite items with aromatic smoke.

An unpleasant odor coming from your favorite coat that just can’t be washed? In this case, the item should be hung outside. Frost ideally removes various aromatic traces, so in winter it will be enough to hang the item on the balcony at night. In general, if things smell like fish, it’s better to just wash them.

Prevention

The main measure to prevent bad breath in patients of any age is high-quality oral hygiene and timely treatment of dental diseases. The tips and recommendations below can be used both to prevent halitosis and to improve the effectiveness of its treatment.

1. It is necessary to carry out hygienic treatment of the oral cavity at least 2 times a day. You should brush your teeth immediately after waking up in the morning, and after your last meal in the evening.

2. If you are prone to bleeding and the deposition of bacterial plaque, you should additionally use balms and rinses with medicinal herbs and natural antiseptics (Forest Balsam, Listerine, Asepta). Such products should be used in courses - 2-3 weeks every 3-4 months.

3. Incorrect or irregular nutrition can provoke the appearance of an unpleasant odor, so it is important to adjust your diet and habits.

4. After eating, you should rinse your mouth with boiled water so that there are no pieces of food left in it, which are a breeding ground for bacteria.

Persons who practice oral sex should brush their teeth (at a minimum, thoroughly rinse your mouth with water or mouthwash) after each contact.

Foul odor from gums is a common dental problem that can only be solved with an integrated approach. Treatment should begin with a visit to the dentist and a complete sanitation: removal of necrotic tissue, relief of inflammatory processes, extraction of teeth that cannot be treated or restored. If the cause of halitosis is diseases of the gastrointestinal tract or larynx, treatment also involves the sanitation of existing infectious foci. Any local remedies (oral sprays, rinses, chewing gums) only mask the problem for a short time, but do not solve it completely, creating conditions for the development of possible complications.

Causes of fishy odor

Being a tasty and healthy product for humans, fish nevertheless has a specific smell. The smell of freshly caught sea fish is similar to the smell of green leaves or cucumbers. Individuals caught in rivers are distinguished by natural mushroom aromas or grass that has just been mown.

And the whole reason is that fish tissues contain TMAO (trimethylamine oxide) compounds, which are necessary to maintain osmotic pressure in the cells. The substance has a subtle odor. But after several hours of storage, a specific smell actively appears in the caught fish.

Rapid TMAO to TMA (trimtylamine) occurs. The latter has a fishy smell that is easily recognizable to any of us. Its durability is explained by the following: TMA penetrates easily into leather, wood, and clothing fabrics.

Why does onion and garlic cause bad breath?

Before we start saving your situation, let's figure out why eating onions and garlic affects our breath so much. In fact, there are many reasons for this, but the main one is the increased content of sulfur compounds in these products.

The main chemical that causes problems with fresh breath is allyl methyl sulfide (AMS). It is this that prevents you from overeating on onions and garlic without affecting your fresh breath.

Moreover, you must understand that rinsing your mouth or brushing your teeth will not be able to completely eliminate the unpleasant odor, because sulfur elements enter the bloodstream after eating. Thus, the smell of onions comes not only from your mouth, but also from inside your body when you start talking.

Moreover, in hot weather this smell can come from the pores, so be vigilant. However, you have every chance to minimize the consequences of taking onions and garlic, which we will talk about now.
