"Falling out teeth, falling tears"
In this scene the dentist pulls out the demon's all teeth.The Chinese poem at the upper side is "Falling the teeth" written by Han Yu.
Last year I lost a tooth
This year I lost a tooth
Suddenly I lost 6 and 7 teeth.
The momentum of falling
especially still won't stop.
All remaining teeth are shaken.
All teeth will fall out,
then it should finally stop at last.
