Thrush in babies is an oral disease caused by Candida albicans infection and is treated with topical medications and vitamin supplements. Thrush is a disease that occurs when Candida albicans infection destroys the oral mucosa and forms a white patchy film on the surface of the oral mucosa. Newborns are mostly infected by the birth canal or acquired from contaminated nipples and breast tools during breastfeeding. 1. Topical medication: 2% sodium bicarbonate solution can be applied before breastfeeding or gargling to change the oral environment and inhibit bacterial growth. Or apply 100,000~200,000U/ml mycotoxin solution locally 2~3 times a day. 2. Supplementary vitamins: vitamin C and vitamin B₂ can be supplemented in moderation, which is conducive to the recovery of oral mucosa. The above drugs need to be taken under the guidance of a doctor on medical advice, do not blindly use your own medicine.
