Aliasing white_teeth → teeth
Link to alias

Reason:

Not needed.
Vast majority of teeth are white, and it's pointless to tag them as such. The color should only be tagged if it's something out of ordinary.

Agreed.
1+.

The only way I could see it being useful is if someone wanted to search for any usually colored teeth, they could search -white_teeth to get them all in one search instead of having to search them color-by-color.

Or if they only wanted normal colored teeth, having to minus out all the other colors out of a search would max out their search string.

So in those two instances, I could see some potential use. But for that to work, we'd have to actually be tagging white_teeth, and when we have so many other more important tags to worry about, I just don't see that happening. So I guess a reluctant agreed from me.
