If you don't know, shut up. I guess youngboul is right. The author does not need to draw teeth. The impression of characters is determined by them teeth. In the first place, it is not drawn with a single horizontal line. There are two front teeth alone. Why is it a row? No gums either. Looking at these makes my nose damp and I'm about to be bitten by these guys. We should respect others. It's just a difference in legitimate thinking and feeling, but the guy who gives a negative rating to his comment is not mature.
