Pupils at Ingoldmells Primary School were taking part in a Young Enterprise scheme this week in 2007.
They were then set a task to imagine there was an empty shop in Ingoldmells which needed filling.
Their teacher Mandy Jackson was astounded when the children decided it should be turned into a dentist.
She said: “They wanted to have a sports, games and music shop but they realised everybody within a community needs a dentist whatever their age, so they decided it wasn’t about what they wanted but what the community needs.
“It was lovely to see.”
Each child received a certificate to show they had completed the day-long course.
Linda Clements, a local business woman and chairman of the school governors, volunteered to help with the scheme.
