Teething fever usually lasts for 2-3 days, and the temperature usually does not exceed 38°C and mostly resolves on its own. When teething, as the teeth penetrate the gums, infection is easily induced and fever of different degrees occurs. In general, as long as the body temperature does not exceed 38.5℃, and the appetite is normal and the mental state is good, this condition suggests drinking more water and can be cooled down by physical methods without special treatment. If the temperature exceeds 38.5℃ and the fever does not subside, accompanied by abnormal crying, irritability and loss of appetite, it is recommended to go to the hospital for relevant examinations in time to clearly diagnose whether there is a combination of other infections and actively treat the symptoms to prevent the baby’s brain nerves from being damaged by prolonged high fever. During the teething period, babies need to pay attention to keeping their mouths clean and hygienic, drink more water, and use teething sticks to relieve swollen and painful gums during teething.
