"Yellow can be fungal, bacterial, or reflux related. The fact that your throat is sore as well suggests it may be reflux, but it could also indicate an infection spreading to your throat."
Yeah, it was my assumption that it was fungal because it came about while I was on Antibiotics and I no longer get acid reflux symptoms like heartburn and indigestion since changing my diet.
Also, some of it spontaneously fell off after drinking tea with a cinnamon stick in it, but cinnamon is also antibacterial so who knows.
Think I'll give oil pulling a go, sounds pretty straight forward and I shouldn't have any trouble finding sesame or sunflower oil.
