I just bought a Thor set on eBay (the polybag one with the cosmic cube) and while everything came in amazing condition, there's a small dot of brown right in the middle of Thor's white teeth.

What should I do to cover this up? Is there such a thing as white sharpie? Or is my Thor doomed to have a bit of potato stuck between his pearly whites forever?

Any help would be greatly appreciated, as the brown is really, really noticeable.
