Yes, teeth, plural. No longer just a tooth, but teeth.
To be strictly accurate, a tooth and a little bit of one poking through next to it, but there is more than one, so it’s teeth.
If you ask him nicely to show you his teeth, he clamps his jaw firmly shut. If you try and pry his lips apart to take a peek, he gets upset (I can’t say that I blame him). They are his teeth, and he shows them off when he feels the need (which is why I took a photo of them).

Little, razor sharp, gnaw on your toes, sink into your tender flesh teeth, and he knows how to use them!
He’s also coming for the camera.
