oral thrush or candidiasis

Generally, people have some amount the candida fungus in the mouth, oral cavities, digestive tract and skin, but they are mostly harmless and under control due to the presence of good bacteria in the mouth. But, on interaction with a certain type of medicine or invasion of other infective germs, the fungus can disturb the balance and go out of control and ultimately lead to oral thrush.

Apart from the foreign invasion, thrush can also occur due to HIV infection, uncontrolled diabetes, cancer, pregnancy, excessive smoking or poorly fitted dentures. It is very common in infants and toddlers and in some cases adults, in the form of creamy white lesions in the tongue, inner cheeks, but can also spread to the roof of the mouth, back of the tongue or even tonsillitis.

It is extremely contagious and may pass on to another person unless treated on time.
