The teeth of several character on BDO are totally different and even many are completely nonexistent.

Here is a list of allcharacter. all screenshot are made in Remastered mode ( The lightning on not remastered mode react really differently ^^)

The disparity of nice teeth are realy serious.
Smiling totally not worth it on some class cause of ugly teeth.

Reason why 99% of people don't use expression settings and 99% of all screenshot of character are with mouth close and inexpressive face.

My biggest concern are the spacing between the 2 jaws

This spacing with the in-game light over pixelate most of the old class teeth and make mostly invisible the bottom tooth rack 

It's horrible and its super strong contrast to everything else ^^

For example of good teeth(Rare) the Archer and Shai ( she literally open its mouth for smiling ;D) had definitely a special treatment in this matter.

Would be agreeable to be able to smile without looking like Princess Tiabeanie !!!
