If your child has been given an injection of local anesthetic, the teeth, lip, gums and cheek may be numb for a few hours. Some children may become upset at the feeling of numbness, interpreting that feeling as pain. Reassure them that this is temporary and that the “funny feeling” will shortly subside and go away. It may help to give the child a popsicle to suck. Wait until the numbness subsides before giving any food.
It is very important that you watch your child closely, in order to monitor accidental biting of the numb lip, tongue or cheek. Should your child inadvertently bite his or her lip, keep the area clean. Saltwater rinses, cool compresses, popsicles and ice cream, as well as children’s ibuprofen, may help. It will take a few days, but the bite will heal. Swelling is normal and will subside with proper care. Antibiotics are not necessary if the swelling is localized to the area of the injury.
