Oral thrush is caused by an overgrowth of fungus called Candida, and it is normally found on skin or mucous membranes. If the environment inside the mouth or throat becomes unbalanced, Candida can multiply.
Thrush infection usually presents itself with painless, white spots or lesions in your mouth. Without complications they will usually go away in a couple of weeks.
If you have frequent occurrences of candida fungus overgrowth you may need to check with your doctor for treatment via an antifungal medication.
Overuse of antifungal drugs can increase your chances that they will eventually not work because the candida fungus develops resistance to medications. Therefore, it is important to be sure of the diagnosis before treating with over the counter thrush treatment or any other antifungal medications.
A natural treatment is to gargle with a little tea tree oil mixed in water, giving it a healthy whoosh around to discover if it thrushes out your problem. Uh, don’t swallow.
