5-year-old child, two upper incisors are loose together, do you want to change teeth?

Children usually start to change their teeth around the age of 6. Most of the physiological shedding of the first deciduous teeth occurs around 6 years old, but some of them are as early as 4 years old or as late as 7-8 years old, so don't worry. Natural deciduous teeth have no roots, and their surfaces are gnawed. Parents should pay attention to observation and don't confuse it with deciduous teeth.

People have to grow teeth twice in their life, that is, primary teeth and permanent teeth. There are 20 deciduous teeth, which usually erupt around 6 months, and grow together at the age of 2-3, and 28-32 permanent teeth (the number of wisdom teeth is 0-4). Generally, they grow together at the age of 6, and the age is 12- 13 (wisdom teeth vary from person to person), so the tooth replacement period is generally 6. There are certain rules for changing teeth. Simply put, it is a certain time and order. According to the principle of "left-right symmetry, first down and then up", left-right symmetry is aimed at teeth with the same name.
