Generally speaking children do not need to have loose teeth extracted. When the permanent teeth come in, the milk teeth will fall out automatically, so there is no need to worry too much. However, if the permanent teeth have already come in and the milk teeth have not yet fallen out, you should take your child to have a dental checkup in time. This is because the permanent teeth below have reached the roots of the milk teeth, so the roots of the milk teeth will be absorbed. After resorption, the milk teeth will loosen and then fall out, and the permanent teeth can grow in. If the milk teeth have loosened but have not fallen out, manual intervention can be performed, in conjunction with the doctor pulling out the teeth, to help the milk teeth fall out and allow the permanent teeth to grow in. If the milk teeth are not loose, but the permanent teeth have grown in and formed a double row of teeth, the milk teeth should be removed promptly. It is important to take good hygienic care after the removal of the milk teeth to protect the wound from infection.
