Thrush is a local lesion caused by the infection of oral mucosa by Candida albicans. Comprehensive treatment measures should be adopted for treatment, starting with addressing the cause. Nystatin and baking soda water can be used to rinse the mouth three to four times daily. Additionally, good oral hygiene must be maintained. All items that come into contact with the mouth should be sterilized before and after eating or feeding, not just daily, as sterilizing only once a day is insufficient. Thirdly, children and patients can consume probiotics to regulate gastrointestinal function and enhance immunity; appropriate medication to boost immune strength can also be taken. Of course, if there are underlying diseases, treatment should still continue. (Medication should be used under the guidance of a professional doctor.)
