Patients with fungal cheilitis often exhibit symptoms such as ulceration at the corners of the mouth, and even cracking. There may be a pus-like white membranous substance at the corners, and sometimes crusting can occur. Patients must pay attention to oral hygiene, avoid irritations in the mouth, refrain from consuming spicy and irritating foods, and avoid frequently licking with the tongue, as these actions may exacerbate the fungal infection.
