My parents home was flooded in 2009. The house almost completely underwater and all of their possessions were lost or damaged beyond repair. A few items simply floated away.
One such item was my Mother's dentures. She had a 'spare' she kept in her dresser that she never liked to wear because they didn't quite fit right and hurt her mouth. So she tended to wear her old ones unless it was a very special occasion. Even though we went through all of their things before throwing them in the dumpster, we never found those teeth.
