E will get around to doing something with his teeth when this is done.
However....
Whatever he does will be balanced against the potential impact on his singing. Why do you think that libeal freak Babs Streisand keeps her nose big? Messing with that changes her vocals.
I kind of laugh when I see all these posts about E going in to the dentist to have a "quick fix" done on his teeth. What he has to do to "fix" his teeth is get his palate cracked and expand his upper jaw. You can't do that in one visit to the cosmetic dentist. His "smile" is too narrow. There's really nothing wrong with his "teeth", per se.
Of course, all that work might change the sound of his tone. It happened to Mr. StrictTime....
