What should be done if a child develops a mouth ulcer after having a tooth extracted?

When a child develops a mouth ulcer after tooth extraction, it is important to first maintain good oral hygiene and avoid food residue remaining on the extraction site and the ulcerated area, in order to reduce the risk of infection. If the ulcer causes significant pain, topical medications such as watermelon frost or cetidine lozenges may be used under the guidance of a physician to help alleviate discomfort. Regarding diet, it is recommended that the child maintain a balanced diet and consume more foods rich in vitamins and minerals, such as fruits, vegetables, and lean meats, to promote healing of the ulcer. In addition, if the mouth ulcer does not heal or recurs frequently, prompt medical attention should be sought for professional diagnosis and treatment. By maintaining oral hygiene, using appropriate medications, and following a nutritious diet, symptoms of mouth ulcers following tooth extraction in children can be effectively relieved. If in doubt, please consult a relevant medical professional.
