The reason why the baby's teeth grow in the wrong order

Generally, when the baby starts to grow teeth, many parents will find that the first teeth to grow are the small front teeth, namely the central incisors, followed by the other teeth. In fact, the baby's teeth grow in a certain pattern and in a certain order. We should pay more attention to protecting the teeth and maintaining the baby's oral hygiene. However, many friends have found that the baby's teeth grow in the wrong order. What is the reason for this? Let me introduce it to you in detail.

Teeth erupting in order is just a general rule, but it is not uncommon for some babies to have their teeth grow in the wrong order or in reverse order. As long as the quality of the teeth is good, it does not matter.

The order of teeth eruption is incorrect. This is related to congenital genetics, and may also be caused by calcium deficiency in the baby. Go to the hospital to check whether there is calcium deficiency and supplement calcium according to the doctor's advice. Pay attention to your baby's calcium supplementation and absorption. If you breastfeed, you should also pay attention to appropriate calcium supplementation.

There are great differences in the time when babies' teeth erupt. Some babies' teeth erupt early, while others erupt late, but as long as it is within the range of individual differences, it is normal. Generally speaking, the order in which babies grow teeth follows a certain pattern, with the left and right teeth developing symmetrically. The specific order in which babies grow teeth is as follows:

1. Central incisors: 2 in mandibular (6 months); 2 in maxillary (7.5 months).

2. Lateral incisors: 2 in mandibular (7 months); 2 in maxillary (9 months).

3. First deciduous molars: 2 in mandibular (12 months); 2 in maxillary (14 months).

4. Canines: 2 in the lower jaw (16 months); 2 in the upper jaw (18 months).

5. Second deciduous molars: 2 in mandibular (20 months); 2 in maxillary (2 years old).

The eruption of baby's deciduous teeth follows such a physiological law: eruption at a certain time, growth in a certain order, and symmetrical development of the left and right teeth. Generally speaking, baby's primary teeth begin to erupt when they are 6-7 months old. However, some babies will grow baby teeth 4 months after birth, while others may not grow them until 10 months or even a year after birth. Every baby's physical development is different, and the time of tooth growth is different. It is normal for a baby to start growing deciduous teeth within 18 months after birth.
