Errrr… are you looking for me to provide you a primary scientific source for how teeth work in animals with differing diets? Most of that is in veterinary texts (which is an amalgam of info), but it’s akin to asking for a scientific evidence for gravity. What you’re asking is too broad to be covered in a single paper and shows a misunderstanding of how scientific studies focus and function. I was simply giving you a primer since you asked, and that blog is good enough for that (and accurate from the portion I read).

I can point you at papers (such as this one on Tooth root morphology as an indicator for dietary specialization in carnivores) which can help explain part of how food selection works in evolution, but I’m not sure what level of information would satisfy you or why you’d even want it?

Here’s one on how tooth wear affects teeth differently based on evolutionary eating habits.

Here’s one on the development and evolution of teeth.

Here’s one on mammalian teeth in specific.
