(CNN) TEETH. Sorry, we got distracted. The first trailer for the "Sonic the Hedgehog" movie dropped this week, and people are having strong reactions to it.

Maybe it's because adapting a beloved '90s video game character is a losing proposition no matter how hard you try, because someone will always feel as if you kidnapped their childhood memories and shoved them through a funhouse mirror.

OR MAYBE IT'S BECAUSE OF THE TEETH.

People are weird about teeth, and always have been. According to dental researcher Rosemary Wells, ancient cultures had a variety of ways of dealing with baby teeth, as described in her essay "The Making of an Icon: The Tooth Fairy in North American Folklore and Popular Culture:"

(1) the tooth was thrown into the sun; (2) thrown into the fire; (3) thrown between the legs; (4) thrown onto or over the roof of the house, often with an invocation to some animal or individual; (5) placed in a mouse hole near the stove or hearth or offered to some other animal; (6) buried; (7) hidden where animals could not get it; (8) placed in a tree or on a wall; and (9) swallowed by the mother, child or animal.
