Definition

Oral thrush is a condition in which the fungus Candida albicans accumulates on the lining of your mouth.

Oral thrush causes creamy white lesions, usually on your tongue or inner cheeks. The lesions can be painful and may bleed slightly when you scrape them or brush your teeth. Sometimes oral thrush may spread to the roof of your mouth, your gums, tonsils or the back of your throat.

Although oral thrush can affect anyone, it occurs most often in babies and toddlers, older adults, and in people with compromised immune systems. Oral thrush is a minor problem for healthy children and adults, but for those with weakened immune systems, symptoms of oral thrush may be more severe, widespread and difficult to control
