When a baby’s upper lip tie, which is the part of the upper lip attached to the gums, breaks and bleeds, the wound needs to be disinfected, cleaned and sutured as appropriate. Usually, if the injury is relatively mild, only a slight break and a small amount of bleeding, and the bleeding is easy to stop, then as long as to keep the wound clean, you can first clean the wound, and then disinfect it with iodine, and then rinse the mouth with light salt water every day after eating, and at the same time, avoid spicy and stimulating and hot food, and do not vigorously brush the teeth so as not to aggravate the wound. If the wound is deeper, the tear is more serious and bleeding, especially if the wound has come into contact with unclean objects, it is recommended to go to the hospital immediately for debridement and suturing. If a child’s upper lip tie is injured, parents must pay more attention and send the child to the doctor in time to prevent the wound from becoming infected and causing more damage.
