It has been reported that some patients have been misdiagnosed with Apthous Mouth Ulcers, when in fact the correct diagnosis in their specific case was Oral Thrush In Adults.
Oral thrush or candidiasis is a disease where the fungus candida albicans grows on the lining of the mouth. It is naturally occurring in the mouth but when your immune system is suppressed it can grow and cause symptoms. These symptoms include slightly raised creamy white lesions on the tongue, and cheeks, redness, burning and soreness that is severe enough to cause difficulty eating and swallowing, a cottony feeling in the mouth, and loss of taste. Oral thrush can be mistaken as conditions such as geographic tongue, coated tongue from poor hygiene, oral lichen planus, oral leucoplakia, and apthous mouth ulcers.
