Toothache, Symptom or Issue?

So, back on the job to continue the story of what happened the night things turned around for good. Ok, there was particularly one tooth that ached like....
Not sure exactly how things came about or why but I remember I realized more and more that my tooth pains actually were a symptom of something being wrong. An health issue where the toothache is a symptom more than an issue or cause in itself. Now we were getting closer to the solution. Must admit though at the time I was not as  rational of thought as may sound. So what did I do? 
I started looking in the refrigerator for various stuffs that mess in there.
Was it milk? No 
Was it cream? No
It was something else but still something white and creamy. Something that starts with Y!
This I put into a drinking glass and put a toothbrush into.


Find out in next post what was in the drinking glass or have you already guessed it?
