The answer lies in your electrons. Under the proper circumstances your mouth is like a lead acid battery. A very weak lead acid battery. The saliva is acidic in order to help predigest food. Now to work with the battery idea a bit, the acid in your mouth can't wait to exchange electrons with the aluminum (just like the lead works with the concentrated acid in the battery) which is an electrical current strong enough to be sensed. You can play with the idea by looking up Potato Clocks and other similar subjects dealing with bio-electricity. The site below deals with your actual question. Better than I can most likely.

When two dis-similar metals touch, electrical energy is created.
When you bite into aluminum (which is metal), your filling/cap/crown (which is also metal) touch each other. Now, an electrical energy is created. You are tasting what this energy does to your nerve endings in your mouth and you are perceiving it as "taste." If your filling is deep, it can also be conducting the electrical energy to your nerve endings in root of the teeth.
It is very weak energy but it IS measure-able. Take any two dissimilar metal, twist it together, take a VERY sensitive electrical meter and dip the whole thing into a liquid. (tap water will do)
It is in order of millivolts (thousandth of a volt), but it is there, and is enough to cause you the sensation.

You have fillings or metallic root - canal posts in your mouth which contain metal. The metal carries a slight charge and is attracked to the aluminum that you are eating?

Actually I thought it was cavities that hurt from foil?

go for a checkup, your fillings may need more work
