Children with thrush mainly suffer from an infection by Candida albicans. In the child’s oral mucosa, including the lips and pharynx, a white membranous substance can be observed, which cannot be wiped off. In this situation, thrush should be considered. Often, it is due to the child repeatedly having an infection, the long-term use of antibiotics or corticosteroids, leading to decreased immunity and thus the occurrence of thrush. Therefore, it is essential to pay attention to oral care. Once thrush is diagnosed, the child should be locally treated with a sodium bicarbonate solution and an antifungal to quickly treat the thrush. At the same time, it's important to prevent diseases from entering through the mouth. All items entering the mouth, like bottles and milk utensils, should be sterilized at high temperatures.
