It is everyone's wish to have neat and white teeth. So many people will correct their teeth because they are not satisfied with them. In fact, strengthening nursing when the baby changes teeth is the best way to help the baby get perfect teeth. So, how should we care? Let's briefly answer some questions that the baby encountered when changing teeth. 1. Retention of deciduous teeth: If the baby reaches the age of changing teeth, the permanent teeth are about to grow, and the upper deciduous teeth are still delayed, it is called retention of deciduous teeth. Permanent teeth can't grow from the normal position, so they have to grow from the abnormal position. If this deciduous tooth is loose, it can be pulled out at home; If it is strong, you must go to the hospital to pull it out. 2. Early deciduous teeth fall off: As the name implies, early "retirement" of deciduous teeth may make the permanent teeth on both sides close to the gap in the middle, resulting in insufficient space for the permanent teeth at this position to grow out of place or be crowded together. In this case, you have to go to the hospital, and the doctor will put on the gap retainer according to the situation and wait for the permanent teeth to grow out. 3, more teeth: redundant, naturally have to be pulled out, but remember to go to the hospital! 4. If the child's first deciduous tooth falls off, but the permanent teeth can't be opened, it will cause the baby to chew with the gums, which will make the gums hard, which is not conducive to the growth of permanent teeth. In this case, you should go to the hospital to check the cause, whether it is nutritional deficiency, especially calcium deficiency. , and pay attention to supplement. 5, deciduous tooth caries: deciduous tooth caries may affect the development of permanent teeth, it is best to go to the hospital to see the degree of influence. If it is too large, it is recommended to remove it to create a healthy environment for the growth of permanent teeth. 6. The gap between the upper teeth is too large: it is caused by the low attachment point of the labial ligament and requires surgery. 7. Eat more chewy food: promote the normal shedding of deciduous teeth and provide space for the growth of permanent teeth. If the front teeth and molars have come out, you can eat some chewy food, such as celery. 8. Nutritional balance: This is very important. Without nutrition, permanent teeth can't grow out in time. If the nutrition is balanced, the permanent teeth will grow out step by step. If you want a balanced diet, don't be partial to food. You should eat vegetables, lean meat, eggs, milk, rice and steamed bread.
