Ive had it before, i think there is a slight chance of it developing after strep throat. Either way, its very painful. I went to a fluid diet for 5 days while using the antifungal mouthrinse. But the video itself is way overdramatized. Nothing to be afraid of.
You can get it by being on antibiotics. It throws off the bacterial balance in your body. Good bacteria keep the yeast in your body and a balanced level. You can also get it from too many sugars in your mouth. Babies can get it from formulas.
