Why can a tooth rot under a crown?

Halitosis or bad breath is a symptom of pathological processes occurring in the body.

According to statistics, in 80% of cases, the cause of halitosis is dental problems, 10% are diseases of the ENT organs, and 10% are diseases of internal organs.

Having felt an unpleasant odor coming from their mouth, people most often turn to a dentist for advice. Often, upon examination, it is discovered that the source of the stale smell is a tooth rotting under the crown.

The main reasons why a tooth under a crown begins to smell bad

Wearing a prosthesis longer than expected . Over time, when wearing a denture for a long time, the gum tissue atrophies, and the area of the neck of the tooth is exposed. A loose connection of the crown to the gum causes the formation of a gap into which food debris gets trapped. It is impossible to remove accumulated substrate from under the crown using traditional methods: toothbrush, rinsing. As a result, an environment favorable for the growth of bacteria is formed under the crown, which in the course of their life emit foul-smelling sulfur dioxide gases.

Violation of the seal between the crown and the tooth . The reason is most often the incorrect installation of the prosthesis or the resorption of the material that was used to fix the artificial crown to the supporting tooth. Pathogenic microflora, penetrating into the formed cavities, causes secondary caries and inflammation of the gums.

If the crown is metal-ceramic, then under the influence of salivary secretions and oxygen in the air, the metal in its composition undergoes oxidation, which causes an unpleasant odor. In addition, the resulting oxides irritate the mucous membranes of the gums and can provoke allergic reactions.

Lack of tooth protection after grinding . One of the stages of preparation for prosthetics is preparation - removal of the enamel coating, which protects tooth tissue from mechanical damage and the action of microbes. If, before installing a permanent prosthesis, the ground tooth is not covered with a temporary crown or treated with cement, then bacteria settle on it and continue their destructive activity under the prosthesis.

Violation of the technological process of manufacturing and installing a prosthesis . If a crown is installed incorrectly, regardless of the reason (insufficient experience of dental technicians and orthopedists, use of low-quality materials), soft tissue injury occurs, followed by infection and the development of inflammation.

Poor oral hygiene . Artificial structures - dentures require special care and cleaning. If you neglect the rules of hygiene, pathogenic microorganisms begin to actively multiply, causing putrefactive processes.

Poor quality dental treatment . One of the main conditions for successful prosthetics is the absence of infection in the oral cavity. If teeth that are subject to prosthetics have a defect in filling the dental canals, a granuloma or cyst filled with pus may form at the apex of the root.

When teeth affected by caries appear under the crown, the decay process continues and ends with complete destruction and death of the tooth.

Symptoms of tooth decay under the crown

The first sign of an inflammatory process under a prosthesis is not pain, as many people think, but an unpleasant odor. This happens because at the stage of preparation for prosthetics, the tooth is usually depulped, that is, the neurovascular bundle, which is responsible for sensitivity, is removed.

An unpleasant taste first appears in the mouth, then a putrid odor is added, which cannot be masked by any chewing gum or mouthwash.
The patient discovers a gap between the crown and the gum, where food debris gets in, which becomes a breeding ground for microbes.
Often, inflammation of the gums develops near the tooth with the formation of soft tissue swelling.
If the tooth has not been pulped, then severe pain is present.
Blackening of the tooth under the crown.

All these symptoms indicate an advanced putrefactive process in the tooth covered with a crown. You should immediately seek medical help from a dentist.

Ignoring the problem leads to dire consequences:

formation of a purulent cyst at the apex of the root;
complete tooth destruction;
the formation of periostitis or gumboil;
spread of purulent infection along with blood or lymph flow to other organs.

general characteristics

A pathological disorder of taste perception is called dysgeusia.
Such a “perversion” of taste sensations can be a sign of the development of neurological, hormonal, mental disorders and other diseases, including those caused by a deficiency of certain substances in the body. If the taste of the products remains unchanged, this diagnosis can be excluded. In this case, we are talking about the temporary persistence of an unusual taste in the mouth, and most often the problem disappears when the cause of its appearance is eliminated.

Why does the taste of blood appear in the mouth?

Inflammation of the gums under the denture is manifested not only by a specific smell from the mouth, but also by the appearance of a blood taste.

Inflammation of the gums around the crown is called gingivitis. Often the cause of gingivitis is rubbing of the mucous membrane due to the irregular shape of the prosthesis. For example, when the lower edge of the crown extends too deeply behind the gum, which leads to injury and bleeding. Blood is an excellent breeding ground for pathogenic microbes that readily multiply, causing inflammation of the soft tissue around a tooth with a poorly fitting denture.

Broken prosthesis that goes unnoticed. The bridge structures scratch the mucous membrane, leaving cuts and abrasions on it.

Bleeding is also the result of poor-quality tooth treatment before prosthetics. Against the background of inadequate filling of the dental canals or incomplete removal of the pulp, pathogenic microbes inside the tooth provoke a purulent process, which is accompanied by tissue destruction with the release of blood.

Taste of blood due to hormonal imbalances

In women, the taste of blood in the mouth may be due to additional reasons. All of them are associated with hormonal changes in the body during a certain period:

Menstruation. The taste may appear before or during menstruation and last a couple of days after it ends.
Taking oral contraceptives. Some birth control pills may cause this side effect. In this case, you should consult your doctor to prescribe other medications.
Pregnancy. Sensations can arise both due to hormonal changes and due to a lack of certain elements in the body (folic acid, iron, B vitamins). The condition is corrected under the supervision of a gynecologist. Additionally, it is recommended to include apples, liver, red meat, legumes, and champignons in the diet.
Climax. Also associated with hormonal imbalance. As during pregnancy, you should enrich your daily diet with iron-containing foods.

The period of pregnancy and menopause may also be accompanied by a taste of blood in the mouth.
Important! Sometimes the taste of iron or blood appears in adolescence, during the restructuring of the body. In this case, there is no need to worry. Once the functioning of the internal organs is normalized, the taste disorder will go away on its own.

What to do to get rid of the smell

Some patients, even having discovered that the cause of such bad breath was a tooth rotting under the crown, for some time they hope to cope with the problem on their own: they rinse their mouth with decoctions of chamomile, calendula, and sage.

Antibacterial rinses and traditional medicine give a temporary effect and are not able to eliminate the root cause of the problem. In addition, frequent rinsing can disrupt the normal microflora of the oral cavity, when beneficial microorganisms die along with harmful ones.

It should be understood that no home remedies will stop the inflammatory process in the tooth, which will only progress and lead to its complete destruction and loss.

Oral diseases

The taste of blood, which gives off iron, also appears in various periodontal diseases. It is associated with both bleeding gums and disruption of the taste buds.

The following oral pathologies can cause discomfort:

Stomatitis. It is provoked by injuries and pathogenic microorganisms. Accompanied by inflammation of the oral mucosa.
Gingivitis. It is characterized by inflammation of the gums, bleeding, and plaque on the teeth.
Periodontitis. Develops as a complication of gingivitis. As the disease progresses, deep periodontal pockets form and tooth mobility appears.
Cheilitis or seizures. Cracks appear in the corners of the mouth, and dry mucous membranes are noted.

In addition, a metallic, bloody taste may occur due to recently installed metal crowns, pins, bridges, dentures, and braces. The sensations are explained by the oxidation of low-quality materials by saliva.

Dental diseases are often the cause of unpleasant symptoms.
Important! Sometimes a blood or metallic taste is caused by tongue or lip piercings.

All these diseases require consultation with a dentist. He will carry out professional teeth cleaning, replace low-quality structures and prescribe the correct treatment.

Additionally, you can use local methods to eliminate taste:

sucking mint candies;
drinking acidified water.
consumption of citrus fruits, cinnamon, mint, nutmeg;
rinsing with water with citric acid or decoctions of chamomile, oak bark, and sage.

Treatment tactics vary and depend on the following factors:

stages of tooth decay;
the degree of spread of the inflammatory process to soft tissues;
condition of root canals.

Treatment options for a tooth under a crown:

If the tooth stump has been preserved and has not undergone a carious process, the layers inside the crown are cleaned and, depending on the condition, it is either replaced with a new one or returned to its place after restoration.

When the upper part of the tooth is destroyed, but the roots are healthy, the stump inlay method is used. This is an orthopedic structure with “legs” that are fixed in the canals of the tooth, and an artificial crown is installed on top.

If the putrefactive process has gone too far and the tooth is completely destroyed, it is removed. As a rule, with long-term inflammation, the soft tissues surrounding the problematic tooth also suffer. Therefore, before proceeding with prosthetics, periodontitis is treated. There are two ways to restore a lost tooth: implantation or a bridge.

When choosing a dental clinic where you plan to get dentures, be sure to find out whether the medical institution provides guarantees for the treatment performed. If damage to the prosthesis occurs during the warranty period due to a medical error, treatment and restoration of the orthopedic structure is carried out free of charge.

Homeopathic treatment

What to do if the tooth under the crown has completely rotted

One type of reconstruction of a severely damaged tooth is a stump inlay. It is a product that replicates the root system of the tooth. A crown is placed on the upper part of the structure protruding above the gum. The method is used only if there are healthy, undamaged roots.

Stump inlays are made of chrome-plated cobalt or alloys with precious metals (gold, silver). Preference is given to gold, as its shade resembles the color of natural enamel. The silver tab, despite its antibacterial effect, is used less frequently, since it shows through the crown as a dark spot.

If the roots are completely rotten and cannot be restored, the tooth is removed.

The choice of one or another method of dentition restoration in case of tooth loss remains with the patient, and his wishes regarding the material, type of structure, as well as financial capabilities are taken into account.

At the reception, a mature woman complains of the taste of chalk in her mouth. In the morning, there is no discomfort in the mouth. Around 1 p.m. every day, a burning sensation appears on the tip of the tongue, like a tingling sensation with needles. This painful, painful sensation intensifies from lunch to evening, when the sensation of the taste of chalk is added. The jaws clench, the chewing muscles tense, the teeth make movements as if grinding something.

These are the complaints that bothered the patient at the time of treatment. And the story of their appearance is as follows.

In March of last year, the patient was fired from her job, completely unexpectedly and in a humiliating manner. This fact in her life is worth telling in more detail.

For more than ten years she worked in a branch of one large organization known throughout the country. The branch was “dying” when, let’s call her Evgenia Filimonovna, came to work at this branch. Very soon she established herself as an excellent worker - proactive, creative, responsible, disciplined, and decent. Very soon she was promoted to department head. The department she headed brought the entire branch into the category of the best branches in the region. For success in her work she was repeatedly rewarded with prizes, certificates, and thanks. She was awarded the “Best in Profession” distinction. Only two people from the region received such badges. Colleagues from the head Moscow office set Evgenia Filimonovna as an example to everyone else at all-Russian conference calls.

Her immediate supervisor of the branch was a mediocre, or even “below average” person; his intellectual limitations did not allow him to delve into the content of the work process. Twice he failed to pass professional certification, but some of his other abilities allowed him to remain in the leadership chair. Evgenia Filimonovna actually managed the employees for him, motivated them to high performance, solved all production problems that her manager had to solve, and raised all performance indicators to the best in the region. He repeatedly told her “thank you!” and added: “What would I do without you?!”

In March, at about 11 o’clock, “two representatives from the region” arrived. Evgenia Filimonovna intuitively felt that “they had come for my Soul”; she was in an anxious state for two hours. Around lunchtime, at about 1 p.m., her bosses called her in and, in the presence of those who arrived, told her that she had been fired. No justification for dismissal was provided. They forced me to sign an order that included the wording “dismissed by agreement of the parties.” As soon as she put her signature, her work computer was “ruined”, so it became impossible to remove her personal photographs and her author’s work from it. On the same day they paid her off, confiscated the keys to the office and turned their backs on her.

The patient spent three weeks in neurotic depression - “in tears and snot”, did not leave the house, did not communicate with anyone. After a month and a half, when the symptoms of depression decreased, psychosomatic disorders appeared - an extremely unpleasant taste of acid in the mouth. Evgenia Filimonovna turned to the dentist. He diagnosed galvanosis and suggested removing the metal crowns. Some of the crowns were removed in June, but the taste of acid persisted, so in August all the dental crowns were removed.

After the crowns were removed, a chalky taste appeared in the mouth and a burning sensation, tingling on the tip of the tongue. I went back to the dentist, who just shrugged his shoulders. That’s when Evgenia Filimonovna turned to me.

After the first session, the taste of chalk in the mouth disappeared, and after the second session of psychotherapy, the tingling, burning of the tip of the tongue and clenching of the teeth disappeared. She arrived for the third session without complaints. By the way, my mood became normal, the obsessive feelings of the psychotrauma I experienced went away, and the ability to smile, joke, and talk about abstract topics appeared.

Now, let's analyze psychosomatic disorders.

In preschool childhood (and in school, too), little Zhenya was raised by her grandmother because her mother “arranged her personal life,” and simply, she abandoned her daughter to her mother and chased after men. Evgenia Filimonovna was etched in her memory by one episode from her childhood connected with her mother.

“I was 4-4.5 years old. Mom arrived home. I missed her very much and was very happy about her arrival. It was the first of May. Mom was in a very beautiful dress, she was going to go to a demonstration. They inflated me with balloons, and I was looking forward to going with my mother to the demonstration - she in a beautiful dress, and me with balloons. Mom didn’t take me and went alone. I ran after her and cried, shouting to her to take me with her. My grandmother caught up with me and forcibly returned me home... Throughout my childhood, I felt useless and abandoned. I was drawn to my mother, but she always pushed me away.

I have known the taste of chalk since childhood. Previously, walls were whitened not with lime, but with chalk. I often licked the walls, picked off pieces of chalk and ate, for which I was often punished. I guess I didn’t have enough calcium, that’s why I was drawn to chalk. I also ate raw potatoes, their taste is somewhat similar to chalk. As for the taste of acid, I don’t know where it comes from. Only all my life I haven’t eaten sour apples, I don’t eat cherry plums or raspberries at all. I can’t stand sour things.”

If Evgenia Filimonovna cannot tolerate the feeling of acid in her mouth, it means that there was an episode in her life, probably in early preschool age, in which she experienced severe suffering and the taste of sour at the same time. Perhaps she was crying, experiencing severe mental suffering, and at that moment she ate something sour. According to the mechanism of a conditioned reflex, the connection between suffering and sour taste was closed. Her mind couldn't remember anything like that. But this does not mean that such an event did not happen in her life. Just like that, out of the blue, a dislike for sour taste will not develop for life.

After the neurotic depression ended, her suffering did not disappear, but moved to the psychosomatic level. Therefore, sensations of acid in the mouth appeared, according to the mechanism of a conditioned reflex formed in distant childhood. This time she was deprived of her job with her self-esteem humiliated. Probably, in childhood, there was an episode when she was also deprived of something dear to her and at the same time her self was humiliated. According to the mechanism of a conditioned reflex, she had a feeling of acid in her mouth.

Dental crowns have absolutely nothing to do with this feeling. She wore them before and everything was fine. If Evgenia Filimonovna had contacted me immediately after her dismissal, there would have been no neurotic depression, no psychosomatic disorders, and all the dental crowns would have been preserved.

When the dentist confidently told the patient that the taste of acid would no longer bother her, another unconscious conditioned reflex turned on, but the triggering moment was identical to the first one. The taste of chalk is like a reminder of one’s uselessness and abandonment. Then her mother abandoned her, and now she was kicked out of work “like a mangy dog,” despite all her previous merits.

Clenched teeth and a burning sensation on the tip of the tongue are an unconscious strong desire to express everything to your boss and at the same time a strong prohibition on yourself from realizing this desire.

The time of onset of the symptom - lunch, coincides with the time of severe psychotrauma experienced, again, according to the mechanism of a conditioned reflex. I.M. was right. Sechenov, who proved that “all acts of conscious and unconscious human life are reflexes in their origin.”

From March to December the woman suffered. Two sessions of psychotherapy and torment “like a cow licked it with its tongue.” Psychosomatics is the Soul’s cry for help. The soul screams with body language, turning to someone who can help eliminate mental suffering. And who can eliminate them? only a psychotherapist. So such patients with psychosomatic disorders go from one doctor to another, in a vicious circle, until someone shows the way to a psychotherapist. There are years of suffering. They treat, operate, irradiate...

I asked Evgenia Filimonovna about how her mother arranged her personal life. Has she found herself a husband? In response I heard: “I found a husband, but it’s impossible to say that her personal life was a success...”

I expected this answer. If Evgenia Filimonovna’s mother did not run after men, but raised her daughter with kindness and love, then the Lord would definitely give her the one she had been looking for all her life. A real man, with whom a woman feels happy, will accept and raise the child of his beloved woman as his own. Such a man must be earned. If you don’t deserve it, then no matter how you look for it, you won’t find it. And if you deserve it, then completely unexpectedly for you, miraculously, he will appear in your life. Just remember the plot of the film “Moscow Doesn’t Believe in Tears.”

Good luck and health to you, and happy new year 2015!

PS When the article was posted on the site and the patient read it, she remembered the reason for the sour feeling in her mouth. The unconscious made her aware. When she was 7 years old, on New Year's Eve, all her classmates were preparing for a masquerade ball. The girls said that at the ball they would be a snowflake, a fairy, and a fox. And little Zhenya really wanted to be a princess or a queen, or even a snowflake. Then the new dad came (mom got married this year) with a briefcase and took out a pig costume for Zhenya. “I cried bitterly and said that I would not wear this suit.” But the mother insisted, and instead of the princess, Zhenya appeared in front of her classmates in a pig costume. She felt humiliated and insulted, she saw the mocking ridicule of her peers, pointing fingers at her, and the whispering of the girls. She doesn’t remember how the matinee went. I remember two moments: the terrible feeling of being crushed, humiliated in the Soul and the sour taste in the mouth from the apples and tangerines received as a gift. She ate fruit and tasted sour in this disgusting pig costume. Feelings of humiliation and insult to her self-respect combined with the taste of sour in her mouth, the conditioned reflex to sour closed. That is why, despite the past decades, she did not eat anything sour, so as not to unconsciously revive those extremely difficult memories.

When Evgenia Filimonovna experienced a humiliating, insulting dismissal, her unconscious revived those childhood memories for her through the mechanism of a conditioned reflex. As a result of such dismissal, she, the best in her profession, felt again in a pig costume, at which everyone laughs and mocks. “You are not a queen, and not even a princess, but an ordinary pig!” - that was what was in her Soul on an unconscious level when she lay on the sofa facing the wall, day after day, after her dismissal. Having turned on the feeling of sourness in the mouth, the unconscious forced Evgenia Filimonovna to seek help, first from a dentist, then from a psychotherapist. The goal has been achieved, she has found someone who can alleviate her suffering.

Here is another illustration of how our Unconscious works. It never forgets anything. This Consciousness does not remember, but the Unconscious remembers everything down to the smallest detail throughout life.

What to do if a crown falls off

The reasons why a crown falls off a tooth can be very diverse:

With prolonged use, the cement on which the crown was strengthened dissolves.
Secondary caries, leading to the destruction of the tooth stump and a violation of the tightness of the connection between the tooth and the crown.
Damage to the denture due to heavy load when chewing solid food.

You cannot try to put the crown in its original place on your own and continue to use the prosthesis. This is very dangerous, since the crown, unexpectedly jumping off the tooth, can enter the windpipe and cause suffocation.

It is impossible to properly strengthen the prosthesis at home; only a dentist can do this.

The dentist, after examination and diagnosis, will decide what to do next.

There are several options:

If the crown is only slightly damaged, it can be repaired and replaced.
In case of significant damage or if the service life of the orthopedic structure has come to an end, the prosthesis must be replaced.
If the cause of crown loss is caries, the tooth is treated, and then a decision is made about the possibility of prosthetics.
If a tooth is severely damaged and cannot be restored, it is removed, and then implantation or a bridge is installed.

Rules for caring for fixed dentures

High-quality care of crowns in compliance with all hygienic rules can significantly extend the service life of the product.

Since a regular toothbrush is not able to fully clean all hard-to-reach places, additional care products are used to better treat teeth and dentures.

Dental floss (floss). This is a special thread made of nylon, silk, acetate fibers with a flat or round cross-section, designed to clean interdental spaces. To enhance the effect, they are often impregnated with antiseptics.

Floss - disposable toothpicks with a thread on a frame are used for the same purposes as floss.

Bundle brush . The interdental spaces are cleaned using a brush-brush with many long bristles. Dentists recommend alternating cleaning the spaces between teeth with brushes and dental floss, since some of them (floss) are better suited for narrow gaps, and a tuft brush does an excellent job of cleaning wide gaps.

An interproximal brush with a brush is designed to treat hard-to-reach areas between the crown and adjacent teeth.

An irrigator is a device for cleaning the oral cavity using a water jet supplied under pressure. A pulsating stream of water penetrates into the most inaccessible places, cleanses the surface of teeth and artificial dentures from plaque and food debris in the gum pockets and interdental spaces.

Dentists do not recommend using wooden toothpicks at all. Wood particles get stuck between the teeth, begin to rot and cause inflammation. In addition, toothpicks can easily injure your gums without even noticing it.

Preventive crown care

The prosthesis installed in the mouth is influenced by food chemicals, saliva, and microbes. Without systematic proper care of crowns, they become covered with plaque, lose their original color, and become a breeding ground for infection.

Prevention of the development of infection in the oral cavity, especially under fixed dentures, involves strict adherence to the following hygiene rules:

Teeth should be brushed at least 2 times a day: morning and evening, and if possible, more often. Brushing technique: movements of the toothbrush are performed from the gum to the top of the tooth at an angle of 45°. The procedure time is at least 3 minutes.
Rinse your mouth with clean water after every meal.
For better cleaning of teeth and dentures, it is recommended to actively use additional devices: interproximal and tuft brushes, dental floss.
Use irrigators. To rinse the oral cavity, various agents with an antibacterial effect are used that destroy pathogenic microorganisms.

A well-installed prosthesis with good care will reliably and for a long time protect the tooth from external factors. But if a tooth infection does occur and decay begins, without proper treatment the pathological process will only progress, which will lead to serious complications. To eliminate the consequences, long-term treatment with significant financial costs will be required.

Diagnostics

The first step in finding the cause of an unpleasant taste in the mouth should be a trip to the dentist: he will immediately determine the possible connection of the symptom with diseases of the teeth and surrounding tissues.

If the problem does not go away, you should consult a therapist: a specialist will help you understand the likely causes of the symptom. For an accurate diagnosis, the results of the following studies may be needed:

clinical and biochemical blood tests (liver, kidney tests, glucose levels, lipid profile);
tests to evaluate thyroid function;
Ultrasound of the abdominal organs;
fibrogastroduodenoscopy (FGDS);
pH-metry of the stomach;
tests for Helicobacter pylori infection;
electroencephalography (EEG), magnetic resonance imaging (MRI) of the head.

The choice of diagnostic algorithm depends on the most likely cause of the development of an unpleasant taste in the mouth.
