Thrush is a common oral disease in children, particularly in infants, caused by Candida albicans infection. Thrush is not easy to cure, so it is essential to treat it promptly when an oral infection occurs. It is necessary to apply a suspension of sodium bicarbonate and an antifungal agent locally to the child's mouth, and all items that enter the mouth, such as bottles and pacifiers, must be sterilized at high temperatures. If the child is breastfed, the mother's nipples should also be thoroughly cleaned. Additionally, for children who have been using antibiotics or corticosteroids for a long time, or who have weakened immune systems, it is crucial to maintain good oral hygiene to prevent the occurrence of thrush. Because all these details about thrush need attention, once diagnosed, it must be treated promptly; otherwise, it is truly not easy to recover from. (Please follow medical advice for the use of medication.)
