Children’s gum pus is also a situation that will be seen in the Department of Dentistry, some children are very poor, into the hospital when there are not only pus pockets on the gums, but also the whole face is swollen, this situation is mostly caused by inflammation of the root tip, called apical abscess caused by apical inflammation. The treatment of abscesses on children’s gums is as follows: 1. Smaller abscesses: If only small abscesses appear on the gums and recur, consider the possibility of chronic inflammation and need to go to the stomatology department for professional examination, which generally requires x-rays. Through the X-ray film, we can see the situation of the abscess under the tooth, which tooth it is caused by, and can determine whether the abscess can be eliminated through treatment. 2. Swelling of the face: In more serious cases, not only is there an abscess on the gums, but the whole face is also swollen, which requires not only going to the stomatology department, but also possibly taking the child to the pediatric department for systemic anti-inflammatory treatment, i.e. hanging saline. Once there is a pus on the gum, it usually indicates that the root of the tooth is inflamed, which is one of the more serious cases of tooth decay. In some cases, the tooth can be preserved, but in case of recurrent abscesses, the tooth can only be extracted. Once an abscess appears on the gums, it is an important warning that the child must be brought to the hospital in time.
