Oral thrush is a fungal infection of the mouth. It is not contagious and is usually successfully treated with antifungal medication. It is also called oral candidosis (or candiasis) because it is caused by a group of yeasts called Candida. Symptoms of oral thrush can include: 1  white patches (plaques) in the mouth that can often be wiped off, leaving behind red areas that may bleed slightly. 2  loss of taste or an unpleasant taste in the mouth. 3  redness inside the mouth and throat.
Initially, you may not even notice symptoms of oral thrush. Depending on the underlying cause, signs and symptoms may develop slowly or suddenly, and they may persist for days, weeks or months. Signs and symptoms may include: 1  Creamy white lesions on your tongue, inner cheeks, and sometimes on the roof of your mouth, gums and tonsils. 2  Slightly raised lesions with a cottage cheese-like appearance. 3  Redness or soreness that may be severe enough to cause difficulty eating or swallowing.
