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 diseases. It is in direct connection with the general state of health of the child - the timely growth of teeth in a certain sequence indicates the normal development of his body. The delay may be due to rickets, an infectious disease, prolonged intestinal dysfunction and changes in metabolism. Earlier dentition - endocrine disorders. The discrepancy 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 effect of any pathology.
A newborn does not have a single tooth, although in rare cases it is observed their intrauterine development. In the period between b and 8 months of life in a child, the central incisors of the lower jaw begin to appear, and then the upper one. By the age of 8-12 months, the lateral incisors are first on the lower, then on the upper jaws. By 12-16 months, the first molars erupt, by 16-20 months the canines and by 20-30 months the second molars, which complete the formation of the milk bite.
The eruption of milk teeth is often reflected in the child's well-being. In weakened children, this physiological process is accompanied by general malaise, poor sleep, restless behavior, crying, and a whim. Sometimes the temperature rises to 37.5 ± C, the nature of feces changes, short-term rashes on the body, reddening of the skin are possible. The child’s weight gain is temporarily suspended, and the immune defense is reduced. Consultation of a pediatrician is necessary to establish the true cause of the disease.
In the 7th year of life, milk teeth are replaced by permanent ones, the time of eruption of which, as a rule, coincides with the resorption of the roots of milk teeth and their loss. In contrast, the formation of a permanent bite begins with the appearance of the first molars of the lower jaw and normally ends by the age of 15-18. The central incisors (8-9 years), the first premolars (9-10 years), the canines (10-11 years), the second premolars (11-12 years), the second molars (12-13 years) are consistently cut through. The third molars of the lower jaw, or as the "wisdom" teeth sometimes call them, grow later, often at the age of 20-25 years (see separately for complications related to their difficulty in eruption).
Correct and timely formed bite plays a big role in the normal development of the child's body. Violation of terms of teething (early or late), priority, as well as the absence of one or another tooth requires the attention of a pediatrician and a dentist, since they are evidence of the pathology of not only local, but often of a general nature (the result of mother’s illness during pregnancy or some that anomaly in the health of the child).
For various reasons, a number of deviations can occur in the structure of the teeth, their location and development: the absence of the germ of a tooth, the incorrect position of the tooth axis (horizontal or oblique), causing it to penetrate outside the arch of the dentition or remain 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.
The eruption of the wisdom tooth is difficult. Violation of the normal eruption is most often observed with the eighth teeth of the lower jaw - the teeth of "wisdom." As a rule, it arises due to the lack of space in the lower jaw, since all the others have already appeared before the wisdom tooth, without “leaving” enough space for it. The delay in eruption creates the conditions for the development of the inflammatory process, which grows from a local focus to a spilled one, fraught with grave consequences. The disease is associated with a permanent injury to the gingival margin above the "wisdom" tooth bumps, where an ulcer is formed, which, with an abundance of bacteria in the mouth, 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 is not able to open his mouth even half a centimeter due to pain.
Symptoms and course:The disease is usually accompanied by general malaise, loss of appetite, decreased sleep, an increase in body temperature, sometimes to high numbers (38 ± C and higher). Since it is necessary to prevent the possibility of the process spreading to the surrounding bone tissue and cellulose with the development of acute inflammation of the bone marrow (osteomyelitis) or soft tissues (cellulitis), it is very important to turn to a dentist without relying on home remedies.
Before medical assistance with the aim of alleviating the state, let us take analgin-type analgin (0.5 g) and rinse the mouth with a warm solution of boric acid (half a teaspoon per cup of water) or manganese-acid potassium (pink).
