What should we pay attention to when children have tooth replacement?

When you have a baby at home, parents must master some knowledge related to the baby's growth so that the baby can grow up healthier and stronger. As the baby grows up, the deciduous teeth will fall out and the permanent teeth will grow out. At this time, parents also need to have some knowledge about the child's tooth replacement, so as to avoid the child's teeth growing crooked and tooth decay. So, when do babies usually start to change their teeth? What should you pay attention to when your baby is changing his teeth?

1. When does the baby change teeth?

Under normal circumstances, the deciduous central incisor (central front tooth) of the mandible begins to shake and fall out at the age of 5 to 7 years old. Soon, the permanent central incisor grows in this place; at the same time, the first permanent molar grows behind the second deciduous molar. After that, the other teeth were replaced one after another. The permanent monocuspids and bicuspids can only grow out after the deciduous teeth in the same position fall out. By the age of 12 to 13, all the deciduous teeth have fallen out and have been replaced by permanent teeth. After that, permanent teeth will grow separately: the second molar will grow behind the first molar at the age of 12 to 14, and the third molar will grow after the age of 18. It is normal for some people to not have third molars.

Second, the precautions for tooth replacement:

1. Parents should educate their children to develop good oral hygiene habits from an early age. In addition to brushing their teeth twice a day in the morning and evening, they should rinse their mouths after every meal.

2. Try not to give your children sweets as they can cause tooth decay. Children should not eat anything after brushing their teeth before going to bed.

3. Let your child eat food that requires a long time to chew, so as to stimulate the deciduous teeth more and allow them to retire on time and make way for the permanent teeth.

4. After the deciduous teeth fall out, educate your children not to lick the missing teeth and the newly emerged permanent teeth with their tongues, otherwise it will affect the growth of the teeth and cause them to grow unevenly in the future.

Generally, babies start to change their teeth after the age of five. When the baby is changing his teeth, you should make sure that the deciduous teeth do not fall out and the permanent teeth grow out. You should go to the dentist in time to extract the deciduous teeth to prevent them from growing crooked. Don’t let your baby lick his teeth with his tongue all the time, as this can easily cause the teeth to grow crooked. Teach your children to brush their teeth in the morning and evening and rinse their mouths after meals to avoid tooth decay.
