"He's still disgusted by filth…"
Feinstone, the dentist, who has not gotten over his wife’s infidelity, to the point of going made, flees from a mental institute and goes to heal his traumatism in his home town. After the self-proclaimed dentist of the town gives him a bad treatment, Feinstone once again becomes angry and murders him.
The village is left without a dentist and Feinstone accepts the full-time job. He also meets, in the days that follow, a blonde that he compares to his wife. He tries not to get too involved but when he learns she is frequenting another man, he is plunged back into a psychosis that is felt by his clients. Suddenly, no one comes back from the dentist that amuses himself by vandalizing his patient’s mouths and by crushing their teeth.
