Thrush is a fungal infection, so its treatment is relatively simple. Generally, the approach involves maintaining an alkaline environment in the affected area, such as using 2% baking soda solution to cleanse and apply to the mouth. This 2% baking soda solution is made by diluting the 5% baking soda solution commonly available in pharmacies or hospitals by half, resulting in a 2%-2.5% solution. This can be used to rinse the mouth three to four times a day. After three to four days of cleaning, if there is no improvement, antifungal tablets such as miconazole or fluconazole dissolved in water can be applied to the affected area, typically yielding very good treatment outcomes. If there is no improvement after applying the baking soda solution and the antifungal solution, oral antifungal medication may be considered. In addition to these treatments, I believe prevention is most important. Preventing fungal infections involves maintaining cleanliness of the mouth and hands, ensuring the cleanliness of items such as baby bottles, pacifiers, and spoons, especially ensuring that adults' hands are free of fungal presence.
