Babies will have teeth coming out at a certain month, which often leads to itching and a desire to bite anything they see. This is a normal phenomenon of teething. Itching roots in babies need to be relieved by biting, and teeth will quickly grow out. However, some babies grow teeth very slowly compared to their peers. They have already grown eight teeth, and their babies only grow two teeth. So, what's wrong with babies only growing two teeth at one year old? Let's take a look with the editor:
What's going on with the baby only growing two teeth at one year old
1. Genetic factors
If a baby grows teeth slowly, it may be due to genetic factors, and sometimes there are gender differences. Generally speaking, female babies will grow teeth relatively early.
2. Postnatal factors
After the baby is born, if it is a premature baby, it is very likely that the slow overall development will lead to slow tooth growth.
3. Physical illness
When a child's pituitary gland secretion is abnormal or the development of the ectoderm is incomplete, it can affect the child's tooth growth rate.
4. Oral infection or injury
If the baby's gums are stimulated by external forces, it can also affect the speed of tooth growth. So, parents should pay attention to the safety of their babies in their daily lives and try not to let their fragile oral cavity be harmed.
When should a baby have normal teething
1. Generally speaking, the first tooth grows out at around 4-7 months old, located in the lower two central incisors. After 4-8 weeks, the four upper teeth will grow out, followed by the two lower side teeth one month later.
2. After a total of 8 teeth grow out, followed by the first molars and canines at the upper and lower back, and finally the second molars at the upper and lower back, a total of 20 baby teeth grow out. This stage is mostly completed before the age of two and a half, and after the baby teeth grow out, they must undergo a tooth replacement process to become permanent teeth.
3. The earliest deciduous teeth to fall out are the incisors, which occur around the age of six. As for the canine and molar teeth, they can be used for a longer period of time, with the molar teeth falling off at around 10-12 years old and permanent teeth growing to replace the molar teeth at 13 years old.
There are many reasons why a baby only grows two teeth at the age of one, and parents need to pay more attention to their baby's physical condition. When going to the hospital for a physical examination, trace elements will be checked. If the baby lacks calcium, the teeth will also grow slowly. Of course, other reasons can also cause slow tooth growth, which requires different treatments for different situations. Under normal circumstances, a baby should have grown about 8 teeth by the age of one, and at this time, the baby can eat some complementary foods well.
