When Dr. Dave Dvorak looked into the teenager's mouth, he felt a wave of sadness.
The boy's parents had brought their son to Dvorak, who was caring for Syrian refugees in Greece, because of an agonizing toothache.
"He had braces on his teeth, but hadn't seen an orthodontist for 20 months," said Dvorak. "There was a buildup of plaque and a cavity eroding a back molar."
Dvorak understood why.
"Less than two years ago, this boy's parents were middle-class professionals living in a stable community, thinking about giving their son a nicer smile," he said. "Then their home was bombed and they had to run for their lives."
Dvorak, a 52-year-old emergency room doctor, usually treats patients at Fairview Southdale Hospital in Edina. But twice in the past year, he has volunteered on the Greek island of Samos to treat Syrian refugees stranded there.
After struggling to share the experience of the hordes of Syrians driven from their homes, he hit on a novel idea: He wrote a song about it.
"When you come back from seeing human tragedy on a mass scale, you want to tell people about it and evoke some compassion for the plight of the refugees," he said. "A song is a quicker way to tell a story."
