Oral Thrush, a yeast infection or candiasis, is very common, and thrives on sugar, alcohol, yeast, so limiting them may help, and boosting your immune system since it's an oportunistic infection, not contagious, being your body can't make a balance of the naturally occurring candida in everyones bodies, that basically went out of control. Also, the usual treatment, besides home remedies, proper oral care, is local treatment with antifungals first, like the nystatin, so you don't develop drug resistance. If it goes further, it's treated systemically, usually with the zole medications like clotrimizole, flucanizole (diflucan), etc. it's easily treatable, if treated properly, if not, it can invade the esphogus (esphogitis), stomach, and go into the blood stream from there or through the gums, mouth ulcers. Once in the blood stream it's called invasive or disseminated candiasis, and difficult to treat, intraveniously, and can be deadly, up to 40%.

Probiotcs are often recommended by some doctors, some may not with a compromised immune system, like cancer, which can be dangerous some reports say, but in healthy people it may be ok.

In addition to the WaterPic, my radiation center sprayed my mouth everyday before or after radiation, and that help with the Mucocitis and oral thrush.
