Baby teething delay

Introduction The morning and evening of the baby's teething time is mainly determined by genetic factors. Usually, children start to have long teeth 6 to 7 months after birth. Children with early teeth start to grow teeth in 4 months. Children who have late teeth will not erupt until about 10 months. Individual children will not be able to reach 1 year old. The first deciduous teeth grow, which is related to the speed of bone growth in infants and young children.

Cause

In general, the baby should have a long tooth 6 to 8 months after birth. The first deciduous teeth are the two central incisors in the middle of the mandible, followed by the middle incisors of the upper jaw, then the lateral incisors of the lower jaw and upper jaw (the second in each side), the first deciduous teeth (per 4th on one side), cuspidate (3rd on each side) and second deciduous (last). By the age of two and a half, all the deciduous teeth can be long.

However, due to differences in climate, living standards, and physical fitness, the time for baby teething is slightly different. The time for teething in children is early and late. However, if you have not had a tooth more than 1 year old, you should check with a pediatrician or a dentist.

The total number of deciduous teeth = 4-6 of the infant's age, healthy babies start to deciduous teeth in about 6 months, 6-8 teeth at 1 year old, the total number of deciduous teeth is about equal to the baby's age minus 4?6, such as For 14 months, the number of teeth is 8-10. Generally, the deciduous teeth are 20 before the age of 2 years.

The most common cause of late babies' deciduous teeth is calcium deficiency, which is medically known as vitamin D deficiency rickets (commonly known as pediatric calcium deficiency). Because of the lack of calcium, the baby can be out of the teeth as late as 1 year old, and the enamel is poorly developed and prone to dental caries.

Usually, children start to have long teeth 6 to 7 months after birth. Children with early teeth start to grow teeth in 4 months. Children who have late teeth will not erupt until about 10 months. Individual children will not be able to reach 1 year old. The first deciduous teeth grow, which is related to the speed of bone growth in infants and young children.

Late teething indicates that the child's bones grow slowly, and early teething indicates that the child's bones grow faster, which is of course relative. As long as it is not due to calcium deficiency or disease, the teeth are not late, generally will not affect the growth and development of bones in the future. The growth of the child is mainly caused by the growth of the long bones (bone limbs). The growth of the long bones is mainly carried out in the cartilage tissue between the metaphyseal ends and the epiphyses at both ends of the backbone.

With the increase of age, the growth rate of the long bones of the extremities is much faster than that of the trunk. By the time of the late youth, the bones will stop growing and the children will not grow taller. The child's future height is determined by genetics, nutrition and appropriate exercise, and is not directly related to the morning and evening of the teething time. Some parents should not give their teeth when they see their teeth. They think that they are suffering from calcium deficiency. It is not advisable to give cod liver oil and calcium tablets to their children.

Whether to give calcium to children is mainly determined according to the actual situation of the child's body. The child's teething is not necessarily calcium deficiency, but it should be combined with the examination and the symptoms it performs to make a comprehensive analysis. Calcium deficiency in children often manifests as slow closure of the cardia, hair thinning, sweating, and crying. At this time, under the guidance of a doctor, appropriate calcium supplements and cod liver oil drops are added, and the food supplement is reasonable, which is beneficial to the health of the child. of.

If the child has not had teething for 8 or 10 months, the parents will give the child a large amount of cod liver oil and calcium tablets, which can easily cause excessive or even poisoning of vitamin D. This is harmful to the child's health.

Teeth "bad" reaction fever: Some babies will have different degrees of fever when the teeth just erupt. As long as the body temperature does not exceed 38 ° C, and the spirit is good, the appetite is strong, there is no need for special treatment, and it is enough to give the baby some boiled water; if the body temperature exceeds 38.5 ° C, accompanied by irritability, crying, milk rejection, etc., Seek medical advice promptly and ask your doctor to check if you have other infections.

Rogue (commonly known as drooling): It is a temporary performance of the teething period. The baby should wear a water towel and dry the saliva in time.

Differential diagnosis

Differential diagnosis:

Slow growth: The age and gender height of children are 2 standard deviations below the median, but less than or equal to the median minus 3 standard deviations, which is moderate growth retardation. If the median of the reference population is less than 3 standard deviations, it is a severe growth retardation. This indicator mainly reflects chronic malnutrition in the past or long-term.

Malnutrition: It is a chronic nutritional deficiency caused by long-term deficiency of protein and/or total calories, which is more common in infants under 3 years of age. Mainly manifested as progressive weight loss, weight loss or edema, severe cases often have internal organ dysfunction, affecting the heart, liver, kidney and other organ functions.
