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.
What Happens. Most cases of thrush are mild and clear up with the use of an antifungal mouth rinse or lozenges. Very mild cases of thrush may clear up without medical treatment. It usually takes about 14 days of treatment with an oral antifungal medicine to cure more severe thrush infections. In some cases, thrush may last several weeks even with treatment.
