After tooth extraction, children can consider applying analgesic drugs in the form of ibuprofen suspension. Clinically, for children’s analgesia, the first step of pain relief and analgesic drugs are generally used, and among them, ibuprofen suspension is relatively more commonly used, with relatively small side effects and high medication safety, and can be used by children. For tooth extraction in children, parents must first send their children to a professional dentist and then apply the medication under the guidance of a physician. Since most of the tooth extractions in children are for baby teeth, the extraction is not very traumatic because the baby teeth are relatively small, and children are not very sensitive to pain, so there is no need to apply analgesic drugs in most cases. Clinically, if children have severe pain after tooth extraction, it may be due to the infection of the extraction wound in children, and the effect of applying pain-relieving drugs alone may not be satisfactory, and other treatments are needed.
