Common causes of gum redness, swelling, and recurrent fever in babies include teething, oral infections, and local manifestations of systemic diseases.

1. teething period

During the process of teething, the eruption of teeth in babies can stimulate gum tissue, causing redness and swelling of the gums, and some babies may experience recurrent fever. This is because when teeth erupt, the local gingival tissue is mechanically stimulated, triggering an inflammatory response, and the body may experience mild fever symptoms due to stress. Generally, the body temperature is low, usually not exceeding 38.5 ℃.

2. Oral infection

When the baby's oral hygiene is poor, it is easy to breed bacteria and cause oral infectious diseases such as gingivitis. For example, infections such as Staphylococcus aureus and Streptococcus can cause gum redness and swelling, and inflammatory reactions can lead to fever in the body. The fever caused by bacterial infection can have high or low body temperature, and if the infection is severe, the body temperature may exceed 38.5 ℃.

3. Local manifestations of systemic diseases

Some systemic diseases may also first manifest as redness and swelling of the baby's gums and recurrent fever, such as Kawasaki disease. In addition to gum redness and swelling and fever, it may also be accompanied by conjunctival congestion, lip cracking, and hard swelling of the hands and feet; There are also blood system diseases such as leukemia, and symptoms such as gum swelling and fever may occur, but they are relatively rare.
