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.
In mild cases of thrush, once treatment has begun, relief may be felt in twenty-four to forty-eight hours. In severe cases, the symptoms may take three to five days to disappear.
