No, I don't think oral thrush is that common for people with a good immune system. "Lady" yeast infections are quite common, from using antibiotics. Eating a diet with plain yogurt is good for that, but we don't do much dairy in this house.

I was introduced to thrush when my eldest was a baby. She had a lot of allergies, sinus and ear infections . . . so lots of antibiotics. I was not aware that antibiotics could cause ORAL thrush, but I suppose that makes sense because it can cause "lady" yeast infections.

I am a smoker, and have tried to quit several times. I know that smoking is RECOMMENDED for those who have Ulcerative Colitis, which I have. That's my excuse, and I'm sticking to it.
