A topical, antifungal mouthwash or an orally or intravenously administered antifungal medicine treats thrush. The name "thrush" refers to an infection caused by the Candida yeast growing out of control in the mouth or throat, according to the Centers for Disease Control and Prevention.
Normally, Candida yeast lives on the skin and mucous membranes of the body, causing problems only when it grows out of control, a condition called Candidiasis, explains the CDC. Candidiasis can occur in multiple locations on the body but occurs often in the genitals, where it commonly receives the diagnosis of "yeast infection." Treatment for these instances of Candidiasis is the same, involving a topical or oral antifungal medicine.
Illness, stress and certain medications can contribute to the overgrowth of candida. Symptoms of thrush include difficulty swallowing, a feeling of food stuck in the throat or mid-chest, and fever. Thrush can be diagnosed with a physical examination.
Following good hygiene practices is helpful to prevent thrush, according to WebMD. Brushing the teeth twice a day, flossing once a day, avoiding the overuse of mouthwash products and visiting a dentist regularly are important steps to prevent thrush. Sugar and yeast-containing foods can also contribute to thrush; limiting these in the diet can help prevent thrush.
