What to do if the baby does not grow teeth at eight months old

Infants and young children will start to grow teeth when they are about 8 months old. But not every child will have teeth at eight months old. Therefore, many people think that if a baby does not grow teeth, it means that the baby's development is abnormal. Then is it normal for a baby not to grow teeth at eight months old? If your child is over eight months old and still hasn't grown teeth, what should parents pay attention to?

Although there are no teeth in the mouth when a baby is born, there are already tooth germs in the cheekbones. After a certain period of time, teeth will grow out from the surface of the gums. The process of teeth growing out of the jawbone is medically called tooth eruption, or commonly known as tooth growth.

There is a certain order and approximate time for tooth eruption. For example, the deciduous lower incisors begin to emerge 6-8 months after birth, and all 20 deciduous teeth will grow in by the age of two to two and a half. Because each child's development is different, some may be earlier and some may be later.

If the teeth have not emerged after the child is one year old, you should ask a doctor to check the cause. If a child suffers from rickets, severe malnutrition, congenital bone development disorders, etc., the calcification of the teeth will be affected and the eruption time will be delayed.

The order of the emergence of deciduous teeth

Name of deciduous teeth Number of teeth at the time of eruption Total number of teeth in months

2 lower central incisors May-October 2

Upper incisors/lower lateral incisors 4/2 6-14 months 8

First deciduous molars 10-17 10-17 months 12

Fangs 4 18-24 16

Second deciduous molars 4 20-30 months 20

Mothers can also go to the hospital to check trace elements to see if calcium supplements are needed. The time of teething for babies varies. The earliest deciduous teeth begin to erupt at 4 months, but most babies start to grow teeth after 6 months. Teeth usually grow in pairs. The lower incisors (front teeth) appear first, followed by the upper incisors, then the lateral incisors, then the premolars and canines, and finally the molars. Generally, all 20 deciduous teeth will appear by the age of 3.

The appearance of a baby's first tooth may occur at different times, but it is generally normal for it to appear between 4 and 12 months. If the baby has not grown teeth by the age of one, there is no need to worry as long as other development is normal. Only in very rare cases may late tooth eruption be due to metabolic disorders, but usually this will not only be reflected in the teeth, but also in other aspects. The order of tooth growth is related to genetics, calcium content in the body, whether the deciduous teeth are missing, etc. Observe whether the baby has other abnormal behaviors, such as crying at night, sweating, baldness on the back of the head, growth and development, etc. If these phenomena occur, it is recommended to go to the hospital to check blood calcium.

If your baby has obvious signs of calcium deficiency, such as irritability, restlessness, restless sleep, easy to be startled, crying at night, sweating, occipital protrusion, etc., it is best to go to the hospital to check for trace elements, use medication according to the doctor's instructions, supplement calcium and cod liver oil in time, and have regular check-ups.

The best time to supplement your baby with cod liver oil is between half a month after birth and two years old. If the baby has no obvious signs of calcium deficiency, there is no need to supplement calcium. Just take 400IU-800IU of cod liver oil every day until the age of two. In the northern region, it can be extended to three years old. This is a preventive amount. Because breast milk and milk powder contain high calcium content and very little vitamin D, calcium supplements can meet the baby's current body needs. Cod liver oil promotes calcium absorption, so cod liver oil must be supplemented additionally.

In addition, sunlight exposure to the skin is also the best way to absorb calcium. If it is summer, you can let your baby bask in the sun for two hours a day, but avoid direct exposure to strong sunlight. You can choose Icosin as cod liver oil, which has good absorption effect and can also be put in milk powder for consumption.

Two reasons for late eruption of deciduous teeth

(1) It may be that the gingival hyperplasia makes it difficult for the deciduous teeth to penetrate;

(2) The baby may suffer from rickets. Due to the lack of vitamin D, the calcium and phosphorus metabolism in the body is abnormal, resulting in delayed development of tooth germs and delayed eruption of deciduous teeth.

In addition, if the baby suffers from hypothyroidism, endocrine disorders, and growth hormone deficiency, the eruption of deciduous teeth will be affected. You should also pay attention to whether your baby's deciduous teeth erupt too late due to congenital tooth loss. You can take your baby to the hospital for an X-ray.

If it is caused by hypertrophy of deciduous teeth, the gums can be surgically cut to help the deciduous teeth erupt. If the deciduous teeth erupt too late due to systemic diseases, the cause should be identified as soon as possible with the help of a doctor, and the eruption of deciduous teeth should be promoted based on symptomatic treatment.
