Used-teeth salesperson
For much of the 20th century, access to decent dental treatment was limited, particularly in Europe, and many people who couldn’t afford to visit the dentist resorted to buying second-hand false teeth when their pearlies had rotted away.
The foundation of the NHS in 1948 ended the icky trade in the UK, though it carried on in other parts of Europe for a while longer – this photo was taken in Amsterdam in 1955.
