Insecure about his teeth in his youth, Amis spent $20,000 on extensive dental work, including the removal of his rotting upper teeth. He denied he had the work done out of vanity. In an interview about his autobiography, Amis
said, “In one of those soul-searching media pieces at the time, I remember Mark Lawson saying, 'There has been a lot written about his teeth, and maybe we should have been told more about the teeth to make sure we got that right.' And I would like to say to Mark, 'Here's more about the teeth, and perhaps you can now see that it wasn't your business.' Tell my dentist that it was cosmetic." British people nevertheless saw it as an
act of betrayal.
