Dry mouth with gastritis: why it occurs and how to eliminate it.

One of the symptoms and unpleasant consequences of gastritis is dry mouth.

You can understand the reason for the appearance of dryness and bitterness in the mouth only by understanding the true nature of gastritis and understanding the reasons that provoke its appearance. Gastritis is a pathological condition of the body in which the mucous membranes lining the stomach begin to become inflamed and destroyed, resulting in tissue rejection.

A dishonest attitude towards one’s health and ignoring the problem can lead to complications of the patient’s condition and the development of a stomach ulcer. In case of tissue damage and death, the stomach ceases to cope with the tasks of processing incoming food. The production of gastric juice is significantly reduced, as a result of which the body cannot completely digest the incoming food.

Undigested food continues its movement through the esophagus, the process of fermentation and rotting begins, accompanied by increased gas formation. Gases gradually move along the esophagus towards the oral cavity, causing an unpleasant taste in the mouth and contributing to the formation of an uncharacteristic coating on the tongue.

The problem of dryness is not always associated with the development of gastritis and other serious diseases. Often the unpleasant feeling of dryness in the mouth is caused by eating the wrong foods and drinking alcohol.

Non-pathological dryness can be easily eliminated with a large amount of ordinary drinking or still mineral water; in case of serious illnesses, the disease cannot be dealt with so easily - it may require intervention from a medical specialist.

Causes of dry mouth

Dry mouth can be a physiological phenomenon that does not require treatment. In this case, saliva production decreases temporarily, and after the action of the causative factor ceases, it is restored on its own. It happens:

in the morning after sleep;
with excitement, fear;
with prolonged fasting;
in hot weather or when the air humidity in the room drops below normal for a long time;
with predominance of mouth breathing.

The causes of dryness can be infectious diseases accompanied by fever, poisoning, taking many medications (including analgesics, antiallergic and antihypotensive drugs). In all these cases, the decrease in saliva production is completely reversible.

Other diseases that are accompanied by dry mouth are:

diabetes mellitus (dry mouth is often the first symptom);
pathology of the thyroid gland with reduced function (hypothyroidism);
the onset of menopause in women;
anemia;
avitaminosis;
chronic diseases of the gastrointestinal tract, biliary tract and liver.

In these cases, dry mouth is caused by a violation of the autonomic (nervous) or hormonal regulation of the activity of the salivary glands. Symptoms can be eliminated by adjusting the hormonal status or curing the underlying disease.

Dry mouth may be a physiological phenomenon that does not require treatment

In some conditions, the salivary glands irreversibly reduce or completely stop producing saliva. The most common cause of this condition is Sjögren's disease, a severe diffuse connective tissue disease of unknown etiology. Dry mouth is often its most painful symptom. In addition, the amount of tear fluid sharply decreases, which leads to dry eyes.

Radiation therapy for cancer causes an irreversible decrease in the function of the salivary glands. Part of the tissue of the salivary glands is replaced by connective tissue and ceases to produce secretions.

Finally, in some cases, xerostomia is considered idiopathic. That is, the reason that caused it cannot be established. A mild degree of xerostomia can be overcome by frequent rinsing of the mouth with water acidified with lemon juice, lubricating the lips and corners of the mouth with Vaseline or chapstick, sucking on sugar-free candies, and chewing gum. You can increase saliva production with special exercises. With your mouth closed, it is recommended to move your tongue and cheeks as if rinsing your mouth.

Heavy or fatty foods include bread, many types of meat, fast food and other products. If dryness occurs after alcoholic drinks, then you should know that this happens even after low-alcohol beer. Eating foods with a lot of salt and hot spices has an adverse effect on stomach ulcers. In this case, the symptom of dryness spreads to the lips.

When a patient smokes, when inhaled, the smoke not only enters the lungs, but also reaches the stomach. The vapor contains substances that penetrate the stomach. Harmful smoke further damages the walls of the mucous membrane, which leads to dry mouth. In most cases, when using medications for a long time, dryness is felt. This symptom manifests itself when the patient experiences an imbalance in the water balance of the gastric mucosa.

Otherwise, drug poisoning occurs. The occurrence of bitterness in the mouth along with dryness means excess bile in the esophagus. This combination is accompanied by gastritis of any form. After eating fatty foods, the patient experiences a metallic taste in the mouth.

The appearance of heartburn, bitterness and dryness occurs due to focal hyperplastic gastritis. This leads to the formation of neoplasms. To eliminate the unpleasant taste and dryness, you must follow the recommendations of your doctor.

Peculiarities of symptoms depending on the type of disease

There are two main forms of esophagitis - acute and chronic.

Acute esophagitis is accompanied by the following symptoms:

severe pain in the sternum area;
increased body temperature;
discomfort along the esophagus;
burning sensation and pain in the larynx and neck;
increased salivation;
frequent belching;
violation of the swallowing process;
general deterioration of health.

With timely treatment, they can completely disappear with complete restoration of the functions of all organs.

Chronic esophagitis is characterized by the occurrence of the following symptoms:

prolonged pain in the chest area;
the appearance of signs of gastritis (pain in the stomach) due to disruption of the process of food digestion;
heartburn, hiccups;
periodic nausea and vomiting.

That is why early detection of this disease and proper treatment are important. Otherwise, irreversible changes in the functioning and structure of the esophageal mucosa may occur.

Depending on the form of the disease, esophagitis may be accompanied by the appearance of various symptoms.

Reflux esophagitis occurs due to irritation of the esophagus due to gastroesophageal reflux. It is characterized by the following symptoms:

frequent belching or vomiting, worse after eating, when bending over, or at night;
the occurrence of pain in the chest area;
the appearance of ulcerative lesions of the esophagus, which can be detected during a diagnostic examination;
unpleasant taste in the mouth;
thickened coating on the tongue;
increased temperature (in acute form of the disease);
swallowing dysfunction.

Biliary reflux esophagitis is manifested by the following symptoms:

feeling of heaviness and fullness of food in the stomach;
bitter taste in the mouth;
nausea;
bowel problems (diarrhea or constipation);
bloating;
the appearance of signs of a lack of vitamins and microelements due to a disruption in the absorption of nutrients in the digestive tract. Dry skin, the appearance of “stubs” in the corners of the mouth and other symptoms are often noted.

Duodenal reflux esophagitis is accompanied by the following symptoms:

yellow coating on the tongue;
pain in the abdomen due to increased activity of the biliary tract and intestines;
heartburn;
feeling of fullness in the stomach;
belching.

Based on the degree of damage to the walls of the esophagus, catarrhal and erosive (ulcerative) esophagitis are distinguished.

Catarrhal esophagitis is manifested by the following symptoms:
pain along the esophagus after eating and during the process of swallowing a bolus of food;
irradiation of pain to the interscapular region;
belching;
heartburn;
difficulty swallowing liquid and subsequently solid food.

This form of the disease is characterized by the following symptoms:

heartburn and belching;
nausea accompanied by vomiting;
pain in the sternum;
painful sensations when swallowing food;
feeling of a “lump” in the throat.

Hemorrhagic esophagitis is isolated as a separate form of the disease. This disease occurs as a complication of severe infectious diseases (influenza, sepsis, etc.). Characterized by the following manifestations:

vomiting mixed with blood and a large amount of mucus;
pain in the chest cavity;
belching and frequent regurgitation.

The appearance of blood in the vomit is due to the occurrence of pinpoint or focal hemorrhages in the mucous membrane of the esophagus.

Pseudomembranous esophagitis occurs as a complication of diseases such as diphtheria, scarlet fever, etc., which occur with the formation of fibrinous exudate. In this case, a grayish film forms on the inner surface of the esophagus. After the film is rejected, areas of ulceration and erosion remain in its place, which heal very slowly.

When this form of the disease appears, the patient experiences the following symptoms:

intense pain in the chest area, increasing during eating;
the appearance of blood and traces of films in the vomit.

Exfoliative (membranous) esophagitis occurs as a consequence of a chemical burn of the esophagus or as a complication of certain infectious diseases (for example, sepsis).

Fibrin multilayer films are formed on the inner surface of the esophagus, which are tightly attached to the surrounding tissues. When these films are rejected, large ulcerated areas remain.

The disease is manifested by such symptoms as:

difficulty swallowing food;
severe chest pain;
vomiting blood.

The prognosis of the disease is favorable with timely initiation of treatment.

Diffuse phlegmonous esophagitis develops due to the introduction of streptococci into the damaged mucous membrane of the esophagus. The infection can enter this organ from the mouth, larynx or lungs.

In this case, the following symptoms arise:

pain in the sternum, aggravated by eating;
difficulty swallowing a bolus of food;
vomit;
the appearance of aversion to food.

Associated symptoms

If a person develops dry mouth due to dysfunction of the glands, then he may experience accompanying symptoms:

the voice becomes hoarse;
saliva viscosity increases;
the ability to distinguish the taste of foods is lost;
tongue becomes dry;
there is a foul odor from the mouth;
pain and slight tingling occur in the oral cavity, cracks appear on the lips;
burning sensation on the tongue;
the process of chewing food becomes difficult;
there is a need to constantly moisturize the oral cavity;
it becomes difficult to speak, etc.

Causes

Modern medicine knows the following reasons why people may experience dry mouth:

If a person sleeps with his mouth open during the night or daytime, then after waking up he will feel dryness, which will disappear as soon as he drinks a small amount of liquid
. If a person sleeps with his mouth open during the night or daytime, then after waking up he will feel dryness that will disappear as soon as he drinks a small amount of liquid.
When taking medications for a long time, people may experience dry mouth as a side effect. In this case, patients need to contact their attending physicians, who can adjust the course of therapy and prescribe other medications.
With severe dehydration, which most often occurs against the background of prolonged diarrhea, the mucous membranes dry out, particularly in the mouth. Dehydration can also occur during prolonged exposure to the street in hot weather, as well as during intense physical activity, during which people often use special devices to lose weight.
Dryness in the oral cavity is often a consequence of intoxication of the body, as well as diseases of infectious etiology, in which the temperature rises and the production of saliva is reduced.
If a person abuses alcohol-containing drinks, he will systematically encounter this problem. The mucous membranes in the mouth can also dry out in those people who are not alcoholics, but sometimes can afford to drink too much.

How to get rid of a lump in the throat with reflux

This article explains why you experience a lump in your throat with reflux, what causes it, what other symptoms are, and how you can manage it.

Lump in throat due to reflux

What is reflux?

Everyone has an acid in their stomach that digests and breaks down food. At the top of the stomach is a muscle valve that closes to prevent food and stomach acids from escaping up into the esophagus. If this muscle valve (esophageal sphincter) does not work well, stomach acids can back up into the esophagus, causing reflux or symptoms of indigestion (heartburn).

However, in some people, small amounts of stomach acid can travel further into the back of the throat, affecting the lining of the throat and voice box (larynx) and causing irritation, hoarseness, and a lump in the throat. This is called laryngopharyngeal reflux (LPR) or extra-esophageal reflux (EOR). Its common name is “silent reflux” because many people do not experience any of the classic symptoms of heartburn or indigestion. Silent reflux can occur throughout the day or night, even if a person has not eaten anything. Usually, however, silent reflux occurs at night.

What are the symptoms of silent reflux?

The most common symptoms are:

Feeling of a lump in the throat.
Hoarse, choked or hoarse voice.
The desire to clear your throat.
Difficulty swallowing (especially tablets or solid foods).
Sore, dry and sensitive throat.
Sometimes an unpleasant “sour” or “bilious” taste in the back of the mouth.
Feeling like too much mucus/phlegm is collecting in the throat.
Sudden attacks of coughing or choking at night.
Chronic cough.
Excessive belching, especially during the daytime.

Some people with silent reflux also experience heartburn. Others rarely notice heartburn or never experience it at all (hence the term “silent reflux”). This occurs because the material (known as “refluxate”) does not stay in the esophagus for long. As a result, the contents do not have time to irritate the esophagus and cause heartburn. However, if even a small amount of refluxate reaches the pharynx and larynx, problems can arise. This occurs because the tissues found in the larynx and pharynx are more sensitive to injury and irritation from stomach acids than the lining of the esophagus. Damage to the larynx from gastric reflux affects a person's voice, causes a feeling of a lump in the throat, and can sometimes affect their lungs and breathing.

Lump in throat due to reflux

A lump in the throat is a very common symptom that can be associated with reflux. Other people describe a feeling of tightness or constriction in the throat, or report a feeling of mucus sticking to them or a desire to clear their throat. Many people become concerned that they may have throat cancer, although in fact a lump in the throat is rarely a symptom associated with cancer. Stress can make this feeling worse. It is important to understand that a lump in the throat is just the sensation of a lump, and not an actual lump or growth.

How is silent reflux diagnosed?

Silent reflux is usually diagnosed when an ENT doctor examines your throat and voice box using a small camera on a thin, flexible fiber optic telescope passed through your nose. An ENT doctor or speech therapist who specializes in voice disorders will ask you to describe your symptoms. If your symptoms are severe, your doctor may order more tests to measure acid levels in your throat and esophagus and, if necessary, refer you to a gastroenterologist (a doctor who specializes in stomach and digestive problems).

What Causes Silent Reflux?

It is often unclear what causes silent reflux. There could be a number of underlying causes, such as problems with the stomach, esophagus or the sphincter that separates them. But, in many cases, lifestyle factors such as being overweight, smoking and consuming too much alcohol and caffeine are likely causes. Dietary factors may also play an important role, and spicy or fatty foods, chocolate, and citrus juice are often reported to contribute to silent reflux symptoms.

How is silent reflux treated?

Treatment is usually planned on an individual basis and your doctor or speech therapist will suggest appropriate treatment for you. There are several effective treatment methods:

Making changes to lifestyle and diet.
Take medications to reduce stomach acid or prevent stomach contents from flowing into the esophagus.
Surgery is sometimes recommended to tighten the valve between the stomach and esophagus if medication has not been effective.

Most people with silent reflux need to change their eating habits and also take some medications. Occasionally, over-the-counter antacids/alginates (eg Gaviscon) are recommended. It works by forming a “raft” over the contents of the stomach, so that if something comes back up into the esophagus, it will be less dangerous. This treatment is often very effective, since the enzymes and bile contained in the stomach juices can cause more harm than the acid. They should be taken four times a day - 10 ml after each meal and 20 ml before bed.

Simple antacids without alginate (such as Maalox or Rennie) are much less effective and are therefore not recommended for the treatment of silent reflux. If you are already taking medications for other conditions, please consult your doctor before trying over-the-counter reflux medications.

For other patients, tablets that reduce gastric acidity will be recommended. These are known as proton pump inhibitors (PPIs) (eg Omeprazole, Lansoprozole, Esomeprazole). One dose in the morning and one in the evening (30 minutes to an hour before meals) is usually recommended to treat silent reflux, but regimens may vary for different people. These medications can only be prescribed by your doctor and you should always take them as directed. Sometimes a combination of PPIs and antacid/alginate medications is recommended. Your doctor will help you choose the right combination of treatments that is right for you.

Most people with silent reflux report improvement in symptoms after 2-3 months of treatment, but it may take 6 months or longer for throat and voice symptoms to improve. Stopping your reflux medication suddenly can make your condition worse, which is sometimes called withdrawal syndrome—which is why most doctors recommend a tapering plan. This will ensure that reflux remains under control and that your symptoms do not recur. Your doctor will give you clear advice on how to stop taking your prescribed medications, and you should make sure you follow this advice.

How to get rid of a lump in the throat with reflux?

There are things you can do to reduce the symptoms of your reflux and also reduce the amount of acid produced in your stomach:

Stop smoking. Smoking increases the likelihood of reflux. You are likely to experience reflux after every cigarette.
Eat healthy and adapt your eating habits.
Limit your intake of fatty, fried and spicy foods, chocolate, cheese and confectionery, as these have all been linked to increased reflux.
Coffee, citrus juices and any form of carbonated drinks can make reflux worse as they have been shown to increase stomach acid levels. Drink water or herbal teas instead.
Chewing gum containing bicarbonate of soda (sold as teeth whitening gum) may be helpful.
Eating smaller meals more regularly will help, as will eating slowly, chewing each bite well. Large meals cause increased stomach acid production and place additional stress on the valve between the stomach and esophagus.
Don't lie down after eating.
If you're overweight, try losing weight (but keep in mind that extreme exercise can also cause reflux).
Drink less alcohol, especially before bed, as alcohol worsens reflux. Strong alcoholic drinks and white wine are the most dangerous for reflux.
Raise the head of the bed about 10-15cm (place blocks under the legs/base of the bed at the head end).
Bend at the knees when lifting things. If you bend at the waist, it will put pressure on the contents of your stomach, and bending over will cause acid to rise up your esophagus to your throat.
Wear loose clothing. Tight clothing puts pressure on the stomach contents and can push acid up the esophagus.
Avoid shouting, singing, whispering, or talking in loud backgrounds.
Try to drink at least 2 liters of fluid per day (no caffeine or alcohol).
Use steam inhalations twice a day.

Will I always need treatment for silent reflux?

Usually silent reflux improves with appropriate treatment, but you need to:

Follow the recommendations you are given for lifestyle changes.
Make the recommended dietary changes.
Take your medications regularly as prescribed by your doctor.
Remember that any decision to stop treatment must be made with the knowledge and consent of your doctor.

In one way, having acid reflux and silent reflux is a bit like high blood pressure—if treated, it usually doesn't cause serious medical problems, but without treatment, silent reflux can be serious, even dangerous. For people with severe silent reflux or people who cannot take reflux medications, anti-reflux surgery (to repair the stomach valve) may be recommended. People who have this surgery generally experience relief for many years.

Dry mouth with acute gastritis

If, in addition to dry mouth, the patient experiences the following symptoms, for example, belching, yellow or white coating on the tongue, heartburn, bitterness and pain, then this may indicate an exacerbation of gastritis.

This pathology can develop for the following reasons:

infection with pathogenic microflora (for example, the pathogenic bacterium Helicobacter);
unhealthy diet (abuse of fatty, salty, smoked, fried foods, as well as fast food, sweet soda and instant foods);
smoking (especially on an empty stomach) and systematic consumption of alcoholic beverages;
bad heredity;
thermal or chemical damage to the organ mucosa;
food poisoning;
long-term use of medications, etc.

If a person reveals alarming symptoms, he needs to urgently make an appointment with a gastroenterologist. The specialist will conduct a comprehensive examination, and if the assumptions about the presence of gastritis are confirmed, he will prescribe a medicinal course of treatment. To normalize the process of saliva production, the doctor may prescribe the following drugs: Pilocarpine, Proserin, Galantamine, Potassium Iodite, etc.

As the pathology goes into remission, the patient will disappear from the accompanying symptoms.

Treatment of dryness and bitterness in the mouth with gastritis

If you have gastritis, you need to see a doctor. If this is not possible, then use folk methods to get rid of bitterness and dry mouth.

Drink a glass of flaxseed infusion once a day. It is sold in pharmacies. This is a good way to relieve the symptoms of gastritis.
You can also treat with corn silk. Brew a spoonful of raw materials with boiling water and let it brew for a couple of hours. You need to take the medicine four times a day in small portions. If there is severe discomfort in the mouth, rinses should be used.

Move dinner to an earlier time. Let at least 4-5 hours pass from the time of your last meal to bedtime.
Increase your daily water intake. It is recommended to drink warm mineral water.
Rinse your mouth with sage or chamomile.

Almost always, troubles can be avoided by improving your usual lifestyle. Smoke less and eat better to live longer and happier.

Traditional medicine for gastritis

Coping with dryness and bitterness in the mouth due to gastritis is one thing, but do not forget about the root cause of the symptom. Medicinal herbs for gastritis are also used as additional treatment.

You need to take a tablespoon of yarrow herb, senna, nettle, chamomile, plantain, calendula and a teaspoon of valerian root. Mix everything, add a liter of water and boil for 3 minutes. Let cool, pass through cheesecloth. Drink half a glass half an hour before meals 3 times a day.

You can also take a small spoonful of liquid honey every day on an empty stomach. It envelops the walls and helps the organ recover. Herbs help quickly cope with gastritis. But we must not forget about the constant diet prescribed by the doctor. With the right approach, the pain will soon go away, as will dry mouth due to gastritis.

Dryness is not a serious problem in itself, but only a symptom. The main thing is to figure out the cause, and then all the consequences will go away on their own.

Ways to treat dry mouth

The most common disease of the gastrointestinal tract is gastritis. Some symptoms of the pathology differ in acute and chronic forms, but the sign of dry mouth does not change. It can be confused with the manifestation of a chronic form of pancreatitis. Therefore, it is necessary to know exactly what disease xerostomia occurs from.

To treat this unpleasant symptom, your doctor may prescribe medications. The use of traditional medicine at home requires consultation with a specialist.

Drug treatment

Ultop - prescribed for gastritis with high acidity, which reduces the production of hydrochloric acid.
To eliminate xerostomia, the disease should be combated. The symptom can be eliminated, but the pathology remains. Therefore, the gastroenterologist recommends taking the following medications:

Ultop - prescribed for gastritis with high acidity, which reduces the production of hydrochloric acid. This will help reduce the irritable process of intestinal inflammation.
Ontime - prescribed during increased production of hydrochloric acid.
Maalox - the drug helps the stomach and has an absorbent and enveloping effect. Medicine is prescribed for heartburn and bitterness in the mouth. The main effect of the drug is the restoration process of the gastrointestinal tract.

Physiotherapy – phonophoresis – is prescribed along with the drug Hydrocortisone. The procedure helps with many diseases, including chronic gastritis. The medicine can penetrate deep into tissues using ultrasound. Phonophoresis is considered one of the effective methods of treating gastritis, and as a result, eliminating bitterness and dryness in the oral cavity.

For the treatment of xerostomia and a bitter taste in the tongue due to gastritis, there are many drugs and their analogues. The use of medications without the supervision of a physician may lead to the appearance of new symptoms and intestinal irritation.

Some drugs can cause an allergic reaction. Dry mouth will mean that the medication is not working to restore the body.

Treatment

General recommendations

If xerostomia and abdominal pain appear after eating fatty foods, drinking alcohol or smoking, you should:

Drink plenty of clean water and green tea or ginger-honey drink to remove harmful substances from the body.
Eat warm, soft foods in small portions. It is better to increase the number of meals to 5-6 times a day.
Refuse sweets and confectionery , replacing them with fresh fruits or dried fruits.
Avoid foods that cause gas ( legumes, cucumbers, apples ).
Take activated carbon , which absorbs all toxic substances. The product helps to quickly cleanse the stomach and eliminate cramps.
Use mint lozenges for the throat , softening and restoring the mucous membrane, or suck on ice cubes.
If you feel unwell, avoid excessive physical activity and stop playing any sports.

Medications

Stay up to date! To eliminate unpleasant symptoms caused by serious disturbances in the functioning of the body, the patient is prescribed medication.

The most effective drugs are considered:

Gastal. Combined antacid to reduce high acidity of gastric juice and normalize digestion. The drug is used in the treatment of gastritis and stomach ulcers.
Rennie. Chewable tablets that neutralize excess hydrochloric acid in gastric juice and have a protective effect on the gastric mucosa.
Sulfadimezin. Antimicrobial bacteriostatic agent in tablet form. The medication is prescribed for infectious and inflammatory diseases.
Hofitol. A herbal preparation that has a beneficial effect on metabolic processes. Chophytol has a hepatoprotective and choleretic effect and is used as part of complex therapy.
Festal. An enzyme preparation that helps normalize the functioning of the pancreas and compensates for the insufficiency of exocrine function.
Papaverine. Antispasmodic agent with analgesic effect. Relieves pain arising from spasms of the stomach, intestines and bile ducts.
Duspatalin . A myotropic antispasmodic, indicated for spasms of the gastrointestinal tract and irritable bowel syndrome, characterized by discomfort in the intestinal area and spastic conditions.

Important! The use of traditional medicine recipes to eliminate symptomatic manifestations at home requires consultation with your doctor.

Folk recipes

Before starting to take traditional medicine at home, the patient should consult a doctor.

If there are no contraindications to the use of “old-fashioned” methods, then the patient can try to normalize the process of saliva production with their help:

Before starting to take traditional medicine at home, the patient should consult a doctor.
Pour boiled water into a glass, to which add a small amount of freshly squeezed lemon juice. It is necessary to constantly rinse the mouth until the condition returns to normal.
Before each meal you should drink a glass of clean water, at least half an hour before.
It is necessary to maintain an optimal level of humidity in the room.
Refusal of addictions that provoke drying out of the mucous membranes.
You can eat a piece of pepper (hot), the components of which will help activate the functioning of the glands (salivary).
Every day it is recommended to drink a glass of infusion made from flax seed. This recipe is actively used in folk medicine in the treatment of various forms of gastritis.
Rinse your mouth with a decoction made from corn silk. To do this, you need to pour dry grass (1 tbsp) into a glass container and pour boiling water (1 tbsp) over it. The contents of the container must be infused for at least 2 hours. After this, you need to strain the mixture and use the liquid for rinsing. You can also take it orally, up to 4 times a day, in very small portions.
Regular rinsing of the mouth with decoctions of chamomile or sage will bring benefits.
You should review your daily diet and exclude from it foods that inhibit the process of saliva production, such as pickles.
