Bad Breath Halitosis Forum

I was thinking of buying some Agar Culture Plates. The ones doctors use to determine back bacteria of the mouth. I wanted to take samples from multiple parts of the mouth. For example a plate for each tonsil, the tongue and the throat and see what kinds of bacteria live in there. Basically I think it might help me see the magnitude of bacteria going on back there. It might be a lot or a little. I was just curious to see what's going on in there.
