What's the difference between cute_fangs and snaggletooth_(disambiguation)? Or should they be aliased?

snaggletooth_(disambiguation) is a tag nobody should be using in the first place. If you see a disambiguation tag, you are supposed to remove it and replace it with better tag. I'm not sure why the alternatives have not been listed in the wiki though.

Also cute_fang is a tag that is exclusively used for tiny barely visible cartoony pointy fang(s) poking from character's mounth. A lot of the content under that snaggletooth disambiguation tag does not fit under this definition at all.
