The reason of baby's late teething
First, physical reasons. The baby with good constitution has good spleen and stomach function, so it can absorb all kinds of nutrients required by tooth development. All parts of teeth are highly calcified substances. The calcification of teeth requires many nutrients, including calcium, phosphorus, vitamin D and fluorine. If only one of the nutrients is missing, it will cause obstacles to tooth development. The calcium that Baoma attaches great importance to is indeed one of the most important nutrients.
Second, the cause of gestational age. The development and growth of teeth is a long-term and complex process, rather than the 4-10 months after the birth of our baby. We divide the development of teeth into three stages: growth, calcification and eruption. When the baby is in the mother's stomach, the baby's primary teeth have begun to develop and calcify. The normal baby's deciduous teeth have formed two-thirds of the crowns at birth, with calcification in varying degrees, but the eruption has not been completed. So the shorter the gestational age, the later the time of teething.
Third, the cause of calcium deficiency. The baby's teeth will calcify further after birth, so the growth of teeth can not be separated from sufficient calcium. If the baby's teeth are late, accompanied by emaciation, sweating, sleep disorder, hair sparseness, crying and other conditions, this is the obvious manifestation of calcium deficiency, you can go to the hospital for further diagnosis, and properly supplement calcium under the guidance of the doctor.
Fourth, genetic reasons. It is possible that the delay of teething and the underdevelopment of enamel of primary teeth may be due to the obstacle of tooth development in embryo. The intake of nutrition and the supplement of calcium and vitamin D have a great effect on the development of baby's teeth. In some cases, it is the lack of nutrition of the pregnant mother that leads to the occurrence of late teething.

Fifth, the cause of the disease. Some diseases, such as hypophysis, hypothyroidism and Down's disease, are not only accompanied by the problem of delayed growth of all teeth, but also have the disease manifestations of other systems, which are easy to distinguish.
Sixth, the tooth itself. Because some babies are born without the formation of the tooth bud, so lead to tooth growth disorders.
Time of baby's teething
Tooth formation begins in the womb. During pregnancy, the baby has a tooth bud, which is also the basis of baby teeth. But only one in two thousand babies has teeth when they are born, and most babies will have their first teeth at four to seven months.
If your baby is growing fast, it may have a white tip (usually a lower incisor) at 3 months. If your baby is slow to develop, it may have to wait until he is more than 1 year old to have his first tooth. The last tooth (the second molar, the upper and lower teeth in the deepest part of the mouth) usually does not appear until the baby is about 2 years old. By the age of 3, your baby should have 20 baby teeth.
Generally, the first tooth of a baby will appear in 6-7 months, first the middle two incisors below, and then the top four incisors. Generally, there are six such teeth around one year old: the top four and the bottom two. If the baby is fidgety, drooling and free from disease, it is caused by teething. Don't worry. If the baby sucks his fingers and bites the toys for a long time, he can play with the teething toys that promote the teeth to grow. The toys should be kept clean.
Nursing of baby's teething
1. Don't blindly supplement calcium late in teething
Some parents see their baby 10 months have not teeth, think that children lack of calcium, hastily increase cod liver oil and calcium powder, or even injection of calcium. I don't know that this may harm the baby. The results of blind calcium supplementation may cause the baby to have symptoms such as edema, hyperhidrosis, anorexia, nausea, constipation, dyspepsia, etc. in serious cases, it is also easy to cause hypercalciuria. At the same time, excessive calcium supplementation may also limit brain development and affect growth and development. If the concentration of blood calcium is too high, the deposition of calcium around the cornea will affect the vision, the deposition on the heart valve will affect the heart function, and the deposition on the blood vessel wall will aggravate the vascular sclerosis.

Therefore, if the baby does not have teeth as long as 10 months, parents do not have to worry too much, do not abuse calcium supplements. As long as we pay attention to feeding, add all kinds of auxiliary food reasonably and timely, let the baby take part in outdoor activities and bask in the sun more often, it's not too late to consult the doctor until one year old baby teeth have not come out.
2. Pacifier is not recommended during teething
Some parents often use pacifiers for their babies, which leads to their babies' excessive infatuation with pacifiers. They are always attached to the pacifiers, so they should be careful to affect the tooth development. Long term use of pacifier will not only lead to irregular growth of baby's teeth, but also lead to jaw deformity.
Some babies often chew their fingers, lips and tongue. These habits will also affect the development of teeth. Once parents find that the baby has these small movements, they should try to shift their attention and avoid forming habits.
3. The baby has premonition of tooth growth
Biting: when the baby's teeth erupt, he likes to bite things, such as biting the nipple or putting his fingers into his mouth. At this time, you can give your baby a toy that can bite, so as to stimulate the gums and make the teeth penetrate the gingival mucosa to sprout smoothly.

Salivation: when the teeth erupt, it stimulates the trigeminal nerve and causes the increase of saliva secretion. Because the baby has not swallowed a lot of saliva, the mouth is shallow, saliva often flows out of the mouth, forming the so-called 'physiological salivation'. This phenomenon generally disappears with age.
Fever and diarrhea: a small number of babies will have fever and diarrhea when they have teeth. Parents should take their babies to the hospital for examination and take appropriate medicine.
