provided my Secret Santa present for this year, a dual helping of my purple squirrel doctor, Amethyst du Sciur, both with and without visible teeth. (♪All I want for Christmas is my two front teeth...♫ :p ) Normally, I portray my rodents without visible teeth when their mouths are closed, just as most real life rodents do,* but FloofySpaceBun is correct that rodents are often depicted with their buckteeth showing. Perhaps she's biting her lip as some accessories of hers get emphasized just a wee bit? (With those clothes, she's off work, so would not be in a professional state of mind. :o )
Still, I appreciate them both equally, so thank you, Floofy. :)

* Naked mole rats are the only exception I can think of offhand. Because they use their teeth for digging, their lips are behind the front teeth to keep dirt out of their mouths.
