If the tooth figure pic has some sort of hidden or implied threat associated with it. Maybe there are dark shadows around the teeth, or it gives the impression that something evil is lurking behind those teeth. It could also be that the teeth seem to be part of a larger, more menacing creature that is not fully shown in the pic, which can fuel the horror aspect.
The abnormal appearance of the teeth in the pic can make it suitable for a horror story. For example, if the teeth are extremely large, crooked, or discolored in a very unnatural way, it can create a sense of unease and horror.
Once there was a tooth figure pic that hung in an old dentist's office. Late at night, it seemed to come alive. The teeth in the pic started to chatter and drip with blood. A young cleaner witnessed this and was so terrified that he ran out and never returned to that place again.
A funny tooth fairy story can be created by having unexpected events. Imagine the tooth fairy being chased by a little mouse while trying to get to the child's pillow. Or she gets her wings stuck in a spider's web on the way. Another aspect is when the child in the story reacts in a very different way to the tooth fairy's visit. Instead of being scared or excited in the normal way, the child might be really calm and start bargaining with the tooth fairy for a better gift. This twist on the usual scenario makes the story humorous.
It should have simple and not-too-scary elements. The plot should be easy to understand and not cause nightmares.
Well, in a tooth fairy horror story, it might show the tooth fairy as a malevolent being. It could be that the tooth fairy has been corrupted or is some sort of ancient evil entity that uses the guise of collecting teeth. The story might include elements like children going missing after losing their teeth, and it turns out the tooth fairy is behind it, luring them into some otherworldly and terrifying realm.
Once upon a time, a child lost a tooth. That night, instead of a cute little tooth fairy, a dark figure emerged from the shadows. It had long, sharp claws and a menacing grin. The 'tooth fairy' grabbed the tooth with a force that made the child scream. It then hissed and vanished into the night, leaving the child terrified and with a sense of dread that never fully went away.
The appearance of the tooth fairy could be the scariest. If it has a distorted face, like a grotesque mask with sharp teeth and bulging eyes, it can be really terrifying.
The unique plot. It might have a story that stands out from the common ones, with twists and turns that keep readers engaged.
The deviation from the expected appearance. Usually, we think of the tooth fairy as a small, cute, and friendly being. But in a scary story, if it has a distorted face, sharp teeth, or a menacing look, it becomes scary.
The unknown aspect makes it scary. We're used to the idea of a cute tooth fairy, but in these stories, it's a complete opposite. So, the deviation from the norm is terrifying.
A horror story I heard was about a person who got an infection right after wisdom tooth removal. The infection spread really quickly, and they developed a high fever. They were in so much pain that they couldn't sleep or eat. The dentist had to drain the abscess and prescribe a very strong antibiotic. It took weeks for them to fully recover, and they were really scared of ever having any dental work done again.
