Why does your mouth water after eating something yummy like chocolate? I don't see the point!!?!
The brain registers that food is coming, and instructs the saliva gland underneath your tongue to produce saliva, which helps break down the food as we chew it and makes it softer as it enters the gullet. As this is a subconscious reaction, it will occur even if you are not actually intending to eat the food you see or smell. As an aside, Ivan Pavlov used this reaction to illustrate his experiments on "conditioning" in dogs, but ringing a bell before feeding the dogs. When he withdrew the food, the dogs would still salivate on hearing the bell ring.
Answers: My mouth doesn't water after I eat something nummy, but it sure waters before I eat if I get a good whiff!

Its your mouth getting ready to start chewing and digesting the food; the more saliva produced the easier this is. So the nicer the food looks to you the better prepared your brain tells your mouth to be
I think It means you want more
Maybe a fetish or wierd desire. Or maybe that is the person mouth watering because of being thirsty.
