Causes and Symptoms of Oral Thrush
By Sally Robertson, BSc
Oral thrush or oral candidiasis refers to infection of the mouth with the fungus Candida albicans. It is usually harmless, is not contagious and is easily treated with antifungal medication.
The Candida albicans fungus exists at low levels in the mouth and digestive system in most individuals, but in some cases, overgrowth can occur and lead to symptoms. If this happens, white lesions develop on the tongue and inside of the cheeks. In some cases, the lesions may also appear on the gums, tonsils, the roof of the mouth and the back of the throat.
