Below is an instruction that describes a task. Write a response that appropriately completes the request in English. Please answer in English.

### Instruction:
All 20 of Grant’s baby teeth have fallen out and he has a total of $54 from the tooth fairy. Every time he lost a tooth, he put it under his pillow for the tooth fairy, except for one that he dropped on the way home from school and another he swallowed accidentally. The tooth fairy left Grant $20 when he lost his first tooth. How much did the tooth fairy leave him per tooth after his first tooth, assuming equal money exchanged for each tooth thereafter?

### Response:
Grant’s 20 baby teeth – 1 tooth he dropped – 1 he swallowed = <<20-1-1=18>>18 teeth.
Of the 18 teeth, 18 teeth – 1 first tooth = <<18-1=17>>17 teeth.
For 17 teeth, the tooth fairy left Grant a total of $54 - $20 = $34.
So on average, the tooth fairy left him $34 / 17 teeth = $2 for each tooth after the first.
