If Wolverine's skeleton is completely bonded with Adamantium, why are his teeth still white?

Interesting point - since Wolverine is a fictional character, it could simply be because adamantium teeth are not good looking.

However according to this article It seems to be related that teeth do not have any cells to repair themselves, plus they are exposed to what we breath in and eat.

Maybe the bones that where bonded where only the ones that could repair themselves. Wolverine could heal himself quickly if not instantly, so it would stand to reason that the bones inside the body would be able to cope with the transformation, and the teeth couldn't.

Then again, it is only a theoretical answer for a fictional character.
