After extraction of a baby tooth, the following precautions should be taken: 1. After extraction of a baby tooth, the child should bite down on the cotton ball for 10-20 minutes to prevent bleeding after extraction. 2. The child is asked not to eat food that is too hot to prevent any effect on the blood clot in the extraction wound. 3. Do not keep sucking on the extraction socket, again to prevent the blood clot from falling out of the socket and possibly causing a local infection. Many children can consider taking oral antibiotics for 1-2 days after tooth extraction to prevent the possibility of infection, especially children with poor resistance should pay more attention to this point. 4. If pain or bleeding occurs after extraction of a baby tooth, be sure to return to the hospital in time for consultation, generally the chances of infection and bleeding after extraction of a baby tooth are relatively small, but it is still important to pay attention.
