The easiest way to identify thrush is by observing the location and color of the lesions. Patients can make an initial differential diagnosis by observing and rubbing the thrush. However, a definitive diagnosis needs to be made by a doctor based on examination results. Usually thrush is distributed in the tongue, palate, buccal mucosa and gums, scattered in creamy white patches of white debris, sometimes fused into patches. The surrounding area is normal with no inflammatory reaction. The surface of thrush looks like creamy white milky lumps, and the white patches on the surface can be wiped with a cotton swab to reveal a flushed red welt. The final diagnosis of thrush should be made by a medical professional through a thorough examination to make a definitive diagnosis followed by symptomatic treatment.
