This process is physiological and serves as an indirect indicator of the correct or impaired development of the child. As a physiological act, teething is not a painful phenomenon and cannot cause any disease. It is in direct connection with the general state of the child’s health - timely, in a certain sequence, tooth growth indicates the normal development of his body. Delay in terms may be the result of rickets, an infectious disease, prolonged dysfunction of the intestines and changes in metabolism. Earlier teething - endocrine disorders. The difference in the time of the beginning of the eruption of the central incisors for 1-2 months from the conditional term cannot be considered as the action of any pathology.
A newborn does not have a single tooth, although in rare cases their intrauterine development is observed. In the period between b and 8 months of life, the central incisors of the lower jaw and then the upper one begin to appear in the child. By 8-12 months - lateral incisors first on the lower, then on the upper jaw. By the 12-16th month, the first molars erupt, by the 16-20th month the fangs and by the 20-30th month the second molars that complete the formation of the milk bite.
Teething of milk teeth often affects the well-being of the child. In weakened children, this physiological process is accompanied by general malaise, poor sleep, restless behavior, crying, and caprice. Sometimes the temperature rises to 37.5 ± C, the nature of bowel movements changes, short-term rashes on the body, redness of the skin of the face are possible. The child’s weight gain is temporarily suspended, and immune defense is reduced. To determine the true cause of the ailment, a pediatrician consultation is required.
At the 7th year of life, milk teeth change to permanent teeth, the eruption time of which, as a rule, coincides with the resorption of the roots of milk teeth and their loss. Unlike them, the formation of a permanent bite begins with the appearance of the first molars of the lower jaw and normally ends by 15-18 years. The central incisors (8–9 years old), the first premolar (9–10 years old), fangs (10–11 years old), the second premolar (11–12 years old), and the second molars (12–13 years old) successively erupt. Third molars of the lower jaw, or as they are sometimes called "wisdom" teeth, grow later, often after the age of 20-25 years (see the complications associated with their difficult eruption).
Correctly and timely formed bite plays a big role in the normal development of the child's body. Violation of the terms of teething (sooner or later), the sequence, as well as the absence of a tooth require the attention of a pediatrician and a dentist, as they are evidence of pathology not only local, but often general in nature (the result of illnesses the mother suffered during pregnancy, or then anomalies in the health of the child himself).
For various reasons, a number of deviations can occur in the structure of the teeth, their location and development: the absence of an embryo of a tooth, the incorrect position of the tooth axis (horizontal or oblique), which makes it erupt outside the arch of the dentition or remains in the thickness of the jaw bone. In addition, the incorrect formation of the tooth itself - the size, shape, position, color, lack of enamel coating, etc. Such changes should be analyzed by a specialist.
Teething of "wisdom" is difficult. Violation of normal teething is most often observed with the eighth teeth of the lower jaw - the teeth of "wisdom". As a rule, it arises due to a lack of space in the lower jaw, since all the others have already appeared before the “wisdom” tooth, without “leaving” him enough space. Delay in teething creates the conditions for the development of an inflammatory process that grows from a local focus to a diffuse one, fraught with serious consequences. The disease is associated with a permanent trauma to the gingival margin above the tubercles of the “wisdom” tooth, where an ulcer forms, which, when bacteria are abundant in the oral cavity, causes inflammation. The process quickly spreads to the surrounding soft tissues, including the masticatory muscles involved in the movement of the lower jaw. The patient due to pain is not able to open his mouth even by half a centimeter.
Symptoms and course:The disease is usually accompanied by general malaise, loss of appetite, decreased sleep, fever, sometimes to high numbers (38 ± C and above). Since it is necessary to prevent the possibility of the process spreading to the surrounding bone tissue and fiber with the development of acute inflammation of the bone marrow (osteomyelitis) or soft tissues (phlegmon), it is very important, not counting on home remedies, consult a dentist.
Before medical treatment, in order to alleviate the condition, it is permissible to take painkillers such as dipyrone (0.5 g) and rinse your mouth with a warm solution of boric acid (half a teaspoon per glass of water) or potassium permanganate (pink color).
