Sour breath
Every few weeks this happen. It happened again yesterday. When I eat/drink something my breath turns sour. For example, yesterday I drank diet soda and my breath was sour. And then I drank soy milk and the same happened. After I brush my teeth and used mouthwash and chewed gum, my breath was still really sour.

Also I frequently have a white coating on my tongue. When I use a tongue scrapper,  it never comes off all the way. I can never get rid of it 100%. Is it a medical condition I should be worried about?

I don't think it is anything serious but I would consider seeing your doctor and if you get no satisfaction then see if your dentist might know what is going on.
