Feeding wear or erosion?

[Per Christian]

So I've got this theropod indet tooth that's from the elrhaz formation, or so the seller claims anyway. The tip is missing and I'm wondering if it's due to feeding wear or erosion? The tooth seems to have been quite worn by the owner, the distal carinae is almost worn away, but i suspect it's also eroded some. The angle of the break makes me think it's feeding wear, but il not certain. Any help is appreciated!

I find this question hard to answer, as I'm most familiar with wear patterns on marine reptile teeth, which often show occlusal damage in a completely different way. And while dry and wet bone breaks may give you an impression of whether damage to bone tissue may have occurred ante- or post-mortem, I'm not sure whether the same interpretations of patterns would also apply to teeth. If they do, I agree with Frank's assessment quoted below (from the thread mentioned in the OP):

Very very difficult to make that call.  My guess and would lean more towards it occured post mortem.  I say that because it's not a shed tooth and it's state of preservation.

 

The reason being the break is not a clean break, but rather an uneven one. This would correspond to dry-bone fractures, i.e., something post-mortem, when the tissue already had time to dry out.
