Teeth recolors?

I've tried to make recolors of the default teeth (normal, gap, rabbit, mess) in Sims 4 Studio, but unsuccessfully so. I just found a tutorial explaining that teeth doesn't have their own texture file, but uses the skin template. I think I would need to recreate each of the default teeth with texture files in order to recolor, and I'm not experienced enough to do so.

So - question - does there exist CC recolors out there already?

All I want is the exact same teeth, just not so white, for my poorest sims. Would be great if sims "sleeping under bridges" did not have the same smile as my Global stars... I'm thinking pale yellow/brown, it doesn't need to be detailed, just all-over-recolored. I know there are some yellow teeth in Get Famous, but they are so bright yellow that I'm not sure if they are supposed to be golden or rotten... ha! :) I'm looking for something a bit less dramatic...

Please share a link if you know any...
