One, Two, Buckle My Shoe by Agatha Christie

A visit to the dentist doesn't usually but end up with a visit from the police, but it happens to our favorite protagonist. After he sees Dr. Morely for a tooth issue, the man ends up dead. It is possibly a suicide but Japp would like to talk to Poirot anyway. Alistair Blunt had an appointment with the same dentist and there is a possibility that this was an assassination attempt on the banker. 

There is a sprawling cast of characters in this one including an actress who was also at the dentist but who has since disappeared, a political activist, and the people who live with Mr. Blunt. The solution is a bit convoluted but wouldn't be out of place in a story that was written today.
