What makes your mouth more sensitive to the cold after chewing on mint gum?

Whenever I chew on mint gum, then get a drink of cold water, my mouth will be very sensitive to the cold water.  Why is this?

The oils in mint and other minty plants bind to the nerve receptors that detect cold (similar to the way that the capsaicin in peppers binds to the heat receptors), so your mouth already thinks it's cold. When you add actual cold things, the nerves fire even more, making your brain think that your mouth is colder than it actually is.
