This is odd

Two of my teeth hurt, but there's no rhyme or reason as to why. They've been cleaned, poked, prodded, xrayed, and all is well. They don't always hurt, but seem to hurt if I have ice cream. It's not because it's cold, because I can swish ice water all around the tooth, and even chew on ice cubes, and it's not the sweet/sugar because I noshed on some Skittles and it didn't faze my teeth. I brushed teeth and rinsed after the ice cream, and the ache didn't go away. Also, no reaction if I eat/drink something hot, unless the teeth are already sore, so the teeth aren't infected.

Two Nurofen and the pain goes away and doesn't return, so again, not an infection.

Bizarre.
