Hi stormcat...Hope this helps.....
Oral thrush (oral candidiasis) is caused by a fungus called candida that causes an infection in the mouth. It is not a type of infection that can be passed on to others.
Everybody has some thrush in their mouths, even babies.
It is also possible to get thrush in other parts of the body, such as the vagina, nappy area or nail folds.
Oral thrush most commonly affects people who wear dentures. People who have difficulties keeping their mouth clean, people with diabetes and those who take steroids are also at a higher risk of developing the condition.
Some antibiotics may cause thrush and many people find that taking certain antibiotics encourages the infection to recur, especially if taken over a long period of time.
A dry mouth caused by certain drugs or after chemotherapy or radiotherapy to the head and neck may also lead to thrush.
