The following sentence is taken from Wifey Redux by Kevin Barry:
"He was seventeen, six two, with blonde, floppy hair, and about eight million quids’ worth of dental work."
How to understand the expression "eight million quids' worth of dental work?" Is the author suggesting that "he" has a mouthful of bad teeth that may take eight million pounds to correct, or "he" has perfect teeth that seems to have been corrected by eight million worth of dental work?
