On the relationship between bite and tongue position in the oral cavity

What does tongue position affect?

Language takes part in many important processes:

• determines the taste and temperature of food;
• helps in mixing food and saliva, starting the digestion process;
• facilitates swallowing;
• participates in the formation of speech.

And also, making several thousand movements per day (swallowing movements alone are about 2000), the tongue participates in the formation of the arch of the palate and bite.

The relationship of the jaws in the bite has a close relationship with the position of the head relative to the body and posture in general.

Bite is the relationship between the dentition of the upper and lower jaws during their tight closure. Depending on age, the bite can be milky, replaceable or permanent. Classification of occlusion is not the topic of this article, so I will focus only on the description of physiological occlusion, which is characterized by the following features:

• does not interfere with the process of eating;
• does not distort speech;
• does not spoil the external characteristics of the face.

When the teeth are completely closed, the physiological occlusion meets the following indicators:

• the upper dentition covers a third of the lower dentition;
• all opposing chewing teeth of the upper and lower jaws fit well together;
• a conventional central line drawn vertically along the face divides the jaws into equal halves.

I apologize in advance to orthodontists for such a simplified description of the physiological bite and there may be some other inaccuracies. I hope the meaning of the article did not suffer from this.

For proper growth of teeth, the so-called myodynamic balance must be formed in the oral cavity, that is, the pressure of the tongue from the inside on the dentition of the upper jaw must correspond to the pressure of the muscles of the lips and cheeks from the outside.

Normally, the tip of the tongue is in a neutral position, located behind the upper incisors, without touching them. Where the tongue is when we pronounce the sound “H” is the so-called “resting point”. During each swallowing movement, the back of the tongue is pressed against the palate, stimulating the growth of the upper jaw in width, improving blood supply to the nasal and oropharynx and thus increasing local immunity. The correct position of the tongue at rest and when swallowing is only possible with nasal breathing, while the mouth must be closed. When breathing through the nose, all the air inhaled has time to be purified and warmed up. The air flow passing through the nasal turbinates also stimulates the growth of the upper jaw in width and the harmonious growth of the entire middle third of the face.

Now I will dwell a little on the changeable bite and the problems of the formation of a physiological bite, which become obvious precisely during the change of teeth. Usually this age ranges from 4-5 years to 12-14 years. During the mixed bite, the most intensive growth of the jaw bones occurs, so bite correction is also most effective at this time.

In children who breathe through their mouth, the so-called “adenoid” type of face is formed, the face becomes narrow and long - elongated. Narrow jaws cause a lack of space for permanent teeth, that is, they are crowded. The Gothic palate and lack of space for the back of the tongue creates problems with sound pronunciation.

Children with malocclusion often breathe through their mouths, even if the nasal passages are clear. They develop habitual mouth breathing and begin to get colds more often. It has been proven that mouth breathing reduces blood oxygenation, as well as the transfer of oxygen to tissues. The brain suffers more than other organs from hypoxia. Children become irritable, not assiduous, and not attentive.

The tongue in such children is in the middle (interdental) or low position - between the palate and the lower jaw. When swallowing, it does not rest against the roof of the mouth, but against the teeth. The tongue is a powerful muscular organ and when it is pressed, the teeth deviate from their normal position.

Very often this is combined with weakness of the orbicularis oris muscle, which normally should balance the pressure on the teeth from the outside.

Normally, swallowing should be visible only by the movement of the thyroid cartilage, the face should not tense. If the position of the tongue is incorrect and the orbicularis oris muscle is weak, the child has to use additional muscles to keep the mouth closed when swallowing. He begins to help himself when swallowing with the corners of his lips, facial muscles, neck movements, shoulders, and sometimes even his stomach.

The tongue, in the middle or lower position, blocks the airways and, in order to somehow open them, the child is forced to move his head forward and raise his chin. This unnatural position of the head and neck also changes the upper chest. Orthopedists, seeing such a picture, talk about poor posture.

So, a change in the position of the tongue leads to a change in the position of the head, a distortion of the anatomically correct location relative to each other of the cervical vertebrae, hyoid bone, cartilage of the larynx and soft tissues of the neck, trachea and esophagus, vessels supplying the brain, and nerve trunks that ensure the functioning of all internal organs.

Thus, during a mixed dentition, it becomes extremely important to form nasal breathing and create conditions for the anatomically correct position and functioning of the tongue, because this will contribute to both the normal development of the dentofacial system and the child’s entire body.

• normal chewing, facilitates the functioning of the entire gastrointestinal tract;
• normal swallowing forms a correct bite and harmonious facial features;
• nasal breathing reduces the risk of colds (the air is purified, warmed, lymphoid tissue is not subject to additional stress and does not hypertrophy);
• improves central nervous system function due to sufficient oxygen supply;
• communication function improves due to clear and understandable speech;
• Due to correct posture, a sense of balance, dexterity, and coordination develops.

Correct bite and anatomical position of the tongue are the key to the health and well-being of your child.

I would like to briefly list the factors that can lead to incorrect position and functioning of the tongue:

• Intrauterine factors (multiple pregnancy, abnormalities in the structure of the uterus, increased tone of the uterus during pregnancy, genetic conditions, etc.);
• Traumatic childbirth;
• Prematurity;
• Artificial ventilation in the first year of life;
• Artificial feeding;
• Untimely introduction of complementary foods;
• Lack of solid food in the child’s diet;
• Bad habits: thumb, tongue, cheek, and various objects sucking, prolonged pacifier sucking (more than 1.5 years);
• Premature loss of baby teeth;
• Frequent diseases of the ENT organs, enlarged adenoids.

What to do if you have a coma in your throat? How to fix it?

The feeling of a lump in the throat makes you nervous.

How to make sure that a lump in your throat is not a consequence of your lifestyle?

1. Determine if there have been any stressful situations at work or at home recently, and try to minimize them.
2. Try to understand if there is tension in the neck muscles due to a long sitting position facing down. If your job requires a sedentary lifestyle, you need to take short breaks every 15-20 minutes. In this case, it is advisable to walk a little and make several turns of the head alternately to the right and left.
3. Fitness activities can also contribute to the appearance of a lump in the throat. You need to reduce physical activity and see if the feeling goes away.
4. You need to temporarily give up smoking and alcohol and not strain your vocal cords (do not sing, do not shout).
5. You should switch to fractional meals in small portions at least 5 times a day. Avoid fried, salty, smoked and spicy foods. It is not recommended to lie down or exercise after eating.
6. See if the sensation arises in one specific place. This may be the result of an allergic reaction, such as to dust or wool. In this case, you need to limit contact with the allergen.
7. Female patients should pay attention to whether this sensation appears exclusively before the onset of the menstrual cycle against the background of a heightened emotional state.

If the tips described above do not help you cope with the feeling, you should consult a specialist.

What parents should pay attention to and be wary of

• Breathing through the mouth if the child does not have a runny nose.
• No gaps between teeth by 4-5 years.

Baby teeth are small and there is usually always room for them, even if the jaw has not developed enough. As the child grows up and prepares for a mixed dentition, so-called trema should appear between the baby teeth - small but distinct distances. When baby teeth fall out, permanent teeth will erupt, which are much wider than baby teeth, and they should have enough space for normal growth and the formation of an even, beautiful dentition.

• Observe the child’s swallowing of saliva; normally, swallowing occurs imperceptibly, without tension in the facial muscles.

Usually, during an appointment, a pediatric dentist draws the attention of parents to the emerging problems of forming a correct bite and refers such children to an orthodontist.

If this does not happen, it is necessary to show the child at the age of 4-5 years to a pediatric orthodontist, preferably one who takes into account the functional approach in his work.

Where does the feeling of a lump in the throat come from?

The sensation usually occurs on the front of the neck.
The patient is concerned about the feeling of a lump in the throat, soreness, numbness and a feeling of a foreign body in the respiratory tract. There is a desire to swallow saliva, but a spasm that causes a feeling of a lump in the throat prevents this from happening. In many patients, the lumen of the esophagus narrows, which makes it impossible to eat normally - the bolus of food does not move towards the stomach, causing pain, salivation and vomiting.

What is a lump in the throat?

Many patients are bothered by a slight feeling of fullness in the throat, which does not cause severe discomfort or difficulty breathing. The feeling of a lump in the throat may occur for just a few seconds, or may last for several days in a row. However, the sensations can be more intense: a spasm of the larynx appears, which makes it difficult to breathe and causes a feeling of fear of death. This syndrome was described by Hippocrates, calling its nature “hysterical”³.

How to correct malocclusion and tongue position.

There must be an integrated approach. Modern orthodontics offers various ways to straighten teeth. But as we have already seen, straightening teeth is ineffective without eliminating the causes leading to these changes.

Therefore, the solution to the problem of malocclusion should be aimed at the entire complex of pathological changes: restoration of the anatomically correct position of the tongue, development of the correct stereotype of swallowing, chewing, head position, posture.

Osteopathic treatment offers exactly this approach: restoration or formation of the correct relationship of anatomical structures

1. Correction of weakened or excessively tense muscles of the face, neck, floor of the mouth and the tongue itself, this will lead to the restoration of the correct position of the tongue in the oral cavity and uniform participation of the corresponding muscle chains in the processes of chewing and swallowing.
2. The effect on the bone structures that form the cavities of the nose and mouth leads to the restoration of the physiological volumes of these cavities and helps improve nasal breathing, chewing, swallowing and speech.

3. Motor innervation of the tongue, swallowing and chewing is provided by the hypoglossal nerve, which exits the cranial cavity through the canal of the hypoglossal nerve, where in some cases it may be compressed. Until a certain age, mobility is maintained in this zone and using osteopathic methods it is possible to restore the physiological correspondence of these anatomical structures.
