I recall from the last cat we had around 10 years ago, the vet said the better quality dried foods are nutritionally pretty good for them (and the cat loved it), but they can cause quite a lot of mineral build up around the teeth.
I would imagine that eating a more meat/flesh 'natural' based diet is proably better for the teeth - but who wants to be mucking about with meat.
So feed the cat what's easiest for you and don't worry about its teeth? 😀
