Symptoms of Oral Thrush

In the mouth, thrush looks like creamy white patches or small red spots on the tongue, roof of the mouth (also called the hard palate), gums or throat. Crusting on the corners of the mouth is also a symptom of thrush. Thrush can make it difficult or painful to swallow and can cause chest pain. It can cause nausea and make your food taste different.

Your doctor can usually tell if you have oral thrush by checking your mouth and throat. X-rays or visual examination of your esophagus and stomach with a special instrument called an endoscope may also be necessary for more serious cases.
