Should children's back teeth be replaced?

Generally speaking, babies between the ages of 2 and 6 basically have deciduous teeth, and they will start to change their teeth at the age of six. The deciduous teeth need to be replaced with permanent teeth. Children will replace all their teeth, but during the period of tooth replacement, babies must maintain oral hygiene and develop a good habit of brushing their teeth in the morning and evening. If the baby has cavities, parents need to go to the hospital for treatment in time, and try to let the child eat less sweets.

1. Will children's molars change when they change their teeth?

Will children's molars change when they grow teeth? Children's molars will change when they grow teeth. Children start to change their molars around the age of six, that is, they start to change their milk teeth. All 10 milk teeth in the upper and lower rows must be replaced in the order in which the milk teeth grow. When they are 12-13 years old, all the milk teeth are replaced by permanent teeth.

2. Children's teeth will not change except for the sixth molars.

When children are around six years old, which is when they start to replace their deciduous teeth, their first tooth will grow. This tooth is the "six-year molar" and it will not be replaced. Therefore, if you do not pay attention to protecting it, it will lead to permanent tooth loss. Its early loss will not only greatly reduce the child's chewing function and cause malnutrition in the child, but also affect the development of the jaw and cause the adjacent teeth to tilt and the elongation of the jaw teeth, resulting in a disordered occlusion relationship, which has a very adverse effect on the physical and mental health of children.

3. How many teeth should children replace?

All twenty baby teeth need to be replaced. Baby teeth begin to erupt at around 6 months old, starting with the front incisors of the lower jaw. At around 2 and a half years old, all 20 baby teeth will be replaced by permanent teeth. By around 12 years old, 28 teeth will have grown in total, which varies from person to person. Generally, the number of wisdom teeth is 0 to 4. All 32 teeth usually come out at around 20 years old.

4. The order of children's tooth replacement

There is a certain order for children to replace their teeth. Simply put, it is "a certain time, a certain order, left-right symmetry, first lower and then upper". Left-right symmetry, first lower and then upper refers to teeth with the same name. At around 6 years old, the first permanent molar, also called the sixth-year molar, grows out just behind the last deciduous molar; slightly earlier or at the same time as the lower central incisor, the deciduous lower central incisor falls out and the permanent lower central incisor grows out at around 6 years old; at 7-8 years old, the deciduous upper central incisor falls out and the permanent upper central incisor grows out, the deciduous lower lateral incisors fall out and the permanent lower lateral incisors grow out; at 8-9 years old, the deciduous upper lateral incisors fall out and the permanent upper lateral incisors grow out; at 9-12 years old, the first and second deciduous molars fall out and the first and second bicuspids grow out; at 10-12 years old, the deciduous canines fall out and the permanent canines grow out.

Children will lose their molars when they change their teeth, but the replacement time of molars will be relatively late. So if you have tooth decay in your deciduous teeth during childhood, don’t worry. As long as you protect the permanent teeth that are replaced after they are replaced, you will not have to worry about food and drink for the rest of your life.
