Okay... I've had a trend of submitting random general furry art. XD But hey, this is one of the more amusing ideas that I had.
I asked jakkal to draw Polec here looking rather angry because, well, with those chompers, you absolutely SHRED toothbrushes. I imagine that it's the same for sharks as well.
Subtle land before time shout-out (Which I didn't realize until someone over on her submission posted that LMAO), but I also imagine that in an anthro world, a toothbrush meant for sharptooths would ALSO apply to sharks and crocodiles.
