Worms falling from the tooth
The tooth worm belief: in Northeast Anatolia, a person with toothache puts their head under a blanket, henbane seeds are sprinkled on embers, and the smoke is drawn in through the mouth. It is said that the small worms rotting the tooth fall into the bowl of water below. Researchers note that the tooth worm belief has its origins in Anatolia. Caution: henbane is poisonous, and its smoke is dangerous too.
