What causes swollen gums and mouth ulcers in children?

Children's swollen gums and mouth ulcers may be caused by various factors. 1. Deficiency of B vitamins, vitamin C, or zinc may lead to fragile oral mucosa that is prone to damage, thus causing ulcers. 2. Oral infectious diseases such as gingivitis and periodontitis are also common causes. These inflammations are bacterial in origin and irritate the gum tissue, leading to redness, swelling, bleeding, and pain. 3. Infectious diseases such as thrush, hand-foot-and-mouth disease, and herpetic stomatitis can also result in oral ulcers and swollen gums. Trauma, such as accidental biting or injury to the oral mucosa caused by consuming excessively hot or hard foods, is another significant cause. In response to these symptoms, parents should promptly bring their child to see a healthcare professional and implement appropriate treatment according to the underlying cause, such as vitamin supplementation, topical anti-inflammatory treatment, pain relief, or antiviral therapy. Maintaining good oral hygiene and adjusting the diet are also important to promote recovery.
