I'm not a figure modeller but I heavily use the Genesis 8 digital human from Daz 3D [0] My guess is that teeth haven't been that interesting to date and that the modellers don't have access to hundreds of reference pictures / geometries of teeth for their modelling. As opposed to reference images of skin textures, etc. Tongues are probably the same. In fact I don't think I have ever created a render of a figure with their tongue out. Once they take the time, the teeth should be easy to improve. [0] https://www.daz3d.com/technology/ https://www.daz3d.com/technology/

I would say that modeling teeth with geometry is very easy. The material, lighting, and rendering is the challenge, especially when you consider all of the occlusion (and hard/soft body dynamics) from your lips that is inevitable with teeth. Some form of subsurface scattering[1] is a must, and not easily done in games/apps because you can't really "bake" it like you do for most other textures to run performantly.

  (20 years vfx experience, me) Subsurface scattering is the correct answer. It's a very small area and a very expensive calculation. Teeth are translucent and the coloured lighting on them changes rapidly.
