Teeth VAM's weak spot?

[Henriyk]

Teeth texture It's just not good enough for me!. Let me admit, maybe I set too high demands on V1 in relation to this point, but where other parameters can create a quality product, it is a shame that teeth texture fails. you can easily edit them in relation to size, skewness, or discoloration, etc. But even if you use maps and countless textures and glossery, they still seem inauthentic and doll-like. And it's a shame compared to beautifully created mouth and tongue textures. Maybe I've overlooked something?, use photoshop and zbrush myself.
Have attached (compressed from 16B png to jpg) an example which immediately has depth and variety but in VAM seems quite mediocre, even if you work with light and shadows and etc.
