Recognising saints: tooth and pincers
A tooth and pincers are the common attributes of Saint Apollonia
Saint Apollonia died in 249 AD. Her teeth were extracted and she was threatened with fire unless she renounced her Christian faith. She threw herself into the flames voluntarily.
She is the patron saint of dental diseases and is prayed to by people with toothache. In art she is shown with a golden tooth on a necklace, or a tooth and pair of pincers.
