"Hysteria," according to Gordon, was written in Oxford just before Eliot married Viv. It is unlikely he already was preoccupied with her teeth.
I would be interested in your source for this claim about getting teeth out for sexual reasons--and a very unlikely effect. But the English had notoriously bad teeth for a very long time because of so much sugar in tea.
In 'Hysteria' Eliot wrote of the woman's teeth as "accidental stars".
And in the Lil section of A Game Of Chess:
Now Albert’s coming back, make yourself a bit smart.
He’ll want to know what you done with that money he gave you
To get yourself some teeth. He did, I was there.
//You have them all out, Lil, and get a nice set,//
He said, I swear, I can’t bear to look at you.
And no more can’t I, I said, and think of poor Albert,
He’s been in the army four years, he wants a good time,
And if you don’t give it him, there’s others will, I said.
Oh is there, she said. Something o’ that, I said.
Then I’ll know who to thank, she said, and give me a straight look.
I wonder if any critic has pointed to the practice (then?) among (certain?) young women of having their teeth "all out" in order to provide more sucking/kissing/oral sex (?) pleasure to their partners? Or taken note of this aspect of social life? As does Eliot, perhaps?
And, was Eliot alluding to the "accidental stars" of his first wife, Vivien, in 'Hysteria"?
