Symptoms such as low fever, salivation, irritability and refusal to eat can occur during teething and are normal. If there is no other discomfort, parents need not worry too much, just observe. Teething fever in children is mostly caused by inflammation of the gums, as the teeth erupt by drilling through the gums, which can lead to small wounds that can easily cause infection. At the same time, children like to put toys, fingers, miscellaneous things into their mouths, which can breed bacteria and increase the risk of infection. However, it usually does not cause high fever and the body temperature is mostly between 37.5°C and 38°C. No special treatment is needed and children should drink more water appropriately. During the teething period, children should be given a light and liquid diet to avoid stimulating the mouth and gums as much as possible, and pay attention to oral hygiene, scrubbing the mouth and gums with light salt water once in the morning and once in the evening. If the body temperature exceeds 38℃ and there are obvious symptoms of discomfort, you can take cefprozil granules, pediatric aminoglutethimide granules and other drugs, together with antipyretic paste for treatment. If the body temperature exceeds 39℃ and does not subside for a long time, the child should be admitted to the hospital for examination and treatment after a clear diagnosis. In addition, children’s immunity is low during the teething period, and if they do not pay attention to weather changes, they are prone to catch cold and fever. Therefore, parents need to increase and decrease clothing for infants and children according to the temperature.
