I relate to Lils here
I had my teeth done a few years ago but because I hadn't smiled with my teeth for many years before that, I still can't smile naturally, even though I am super happy with teeth now! But at least I don't feel self-conscious when I talk to people, which is nice.
With Lily, it's almost like she wants to show off the new teeth, so she smiles much wider than she ever had before she had that discolouration.
Like here, she is smiling quite wide but it's not so forced as nowadays, it's like she also is smiling from within in this picture.
