The baby only grows two teeth at the age of one.

Every baby's growth rate is different, especially during teething, some babies grow teeth faster and some slower. If your baby only grows two teeth when he is one year old, this has a lot to do with genetic factors. In addition, if the baby lacks vitamin and calcium supplements during his growth, it will also cause slow tooth growth. Therefore, as parents, you must pay attention to your baby's growth problems and solve and treat them in time.

1. Genetic factors

If a baby's teeth grow slowly, it may be due to genetic factors. Sometimes there are certain differences between genders. Generally speaking, girls' teeth grow relatively early.

2. Acquired factors

After the baby is born, if it is a premature baby, it is very likely that the overall development will be slow, resulting in slow teeth growth.

3. Physical illness

When a child's pituitary gland secretion is abnormal or the ectoderm is incompletely developed, it will affect the child's tooth growth speed.

4. Oral infection or injury

If the baby's gums are stimulated by external force, it will also affect the speed of tooth growth. Therefore, parents should pay attention to their baby's safety in daily life and try not to hurt their child's fragile oral cavity.

When is the normal time for teething in babies?

1. Generally speaking, the first tooth grows out at about 4 to 7 months of age, located between the two central deciduous incisors in the lower row. After 4 to 8 weeks, the 4 upper incisors will grow out, followed by the two lateral incisors in the lower row a month later.

2. After the 8 teeth in total grow out, the first deciduous molars and deciduous canines at the back of the upper and lower parts will grow next, and finally the second deciduous molars at the back of the upper and lower parts will grow, for a total of 20 deciduous teeth. Most of the time, this stage is completed before the age of two and a half. After the deciduous teeth grow out, they must go through the process of tooth replacement before they can become permanent teeth.

3. The first deciduous teeth to fall out are the deciduous incisors, which occurs around the age of six. As for deciduous canines and molars, they can be used for a longer time. Deciduous molars fall off at around 10 to 12 years old, and permanent teeth grow out to replace the deciduous molars at 13 years old.

There are many reasons why a baby only grows two teeth at the age of one. Parents need to pay more attention to the baby's physical condition. Trace elements will be checked during physical examinations at the hospital. If the baby is calcium deficient, the teeth will grow slower. Of course, other reasons can also cause slow teething, which requires different treatments in different situations. Under normal circumstances, the baby should have about 8 teeth by the time he is one year old, and at this time the baby can eat some complementary foods very well.
