During the period of alternating milk and permanent teeth in children, the upper milk teeth become progressively and significantly loose due to the growth of the permanent teeth below. This tooth will sometimes fall out naturally, but sometimes more slowly. Parents who have basic medical knowledge can consider helping their children to remove this tooth. However, it is important to note that there are certain risks associated with extraction because sometimes a tooth that appears to be loose may be difficult or painful to extract, and parents do not have the tools or anesthesia equipment at their disposal to do so, which may cause the extraction to fail and other accidents to occur. Therefore, it is better to go to a professional dentistry department and have the operation of extraction of baby teeth done by a professional dentist.
