Question

What signal did her mother’s false teeth give to the poet ?

Answer 1

that the mother is lying to them

Answer 2

Her mother’s false teeth gave her the signal that if she did not take care of her teeth, she, too, would have to get the false teeth for herself. She had neglected the care of her teeth. She developed many cavities in her teeth. She was likely to lose some teeth. So she thought that her mother’s false teeth gave a sort of warning to her.
