Doctor's Notes on Oral Thrush

Thrush is the name given to a yeast infection of the mouth or throat, most often caused by Candida yeast. Thrush can be linked to yeast infection of the esophagus as well and is sometimes referred to as oral candidiasis. Thrush is more common in people with some degree of immune system suppression than in those with healthy immune systems.

The characteristic symptom of thrush is a raised, creamy, white, curd-like coating that can be seen on the tongue, insides of the cheeks, tonsils, gums, roof of the mouth, or back of the throat. Possible associated symptoms can include pain, redness, burning, loss of taste sensation, mild bleeding, or discomfort. Another symptom can be abnormal sensation in the mouth, such as a “cotton-like” feeling. This can cause pain with swallowing and refusal to eat in young children.
