Scary Teeth

With chompers like those, maybe it's for the best that
his head was cut off...

Makoto: Nagisa, [Rin] called you a loser!
Nagisa: Ay yo, homeboy looks like Shark Week, I ain't messin' with that.

A character smiles, and it is revealed that their teeth are... disturbing.

This trope manifests in myriad ways, from teeth being all askew to being rotten, from being a mouthful of sharp fangs to metallic prostheses, and sometimes even there not being any teeth at all (cute in an infant, disturbing in an adult).

This trope works for a variety of reasons. One of the biggest is that trauma to the teeth is a Primal Fear for most people. Also, teeth are very much associated with youth, vigor and hygiene, so nasty teeth instantly give an image of sickness, dirtiness and malevolence. Sharp, fanged teeth are an universal identifier of a predator, too, so anyone who sees fangs or a maw full of sharp teeth will instantly feel threatened.

Can be an indicator of an evil character, although good ones aren't disqualified (though even the good characters with teeth like this will typically still have some bestial, brutish traits).

Related to Tombstone Teeth, and Fangs Are Evil. Sub-Trope to Monster Mouth. Super-Trope to both More Teeth than the Osmond Family and Jagged Mouth, where the teeth seem to be rigid extensions of whatever passes for the lips.

• In one of ABC's Saturday Morning Bod Squad PSAs, a character called the Yuck Mouth shows the result of not taking care of your teeth, as he has only a few teeth left in his mouth, and one of them is severely rotted.

Anime and Manga

• Black Butler: Sebastian's true form has a mouthful, and he stills shows them sometimes in his butler guise.
• One Piece:
  • Arlong and Hody Jones. Justified as they're both shark fishmen (a sawshark and a great white shark respectively).
  • Anyone can have these whenever they're angry or irritated at something (usually Luffy). Mostly Played for Laughs.
  • Of the Doflamingo Family, Dellinger shows these during his fight with Ideo revealing he is a fishman of fighting fish descent.
  • Losing his mask reveals that Jack the Drought has these, due to being a fishmash.
  • The half-mermaid Charlotte Praliné also has these, and it's justified as her father is said to have been a hammerhead shark merman.
  • Charlotte Katakuri has a mouth full of fangs under his scarf. It's unclear if it's hereditary (many of his siblings are Half Human Hybrids), but he hides it because of past mockery. His two triplet brothers, Daifuku and Oven, don't have those though.
• Viral from Tengen Toppa Gurren Lagann is a shark-type Beastman with feline genetics, and has the choppers to match.
• Naruto:
  • Kisame Hoshigaki has pointed teeth, among other shark-like characteristics. Other members of the Seven Swordsmen of the Mist also have such teeth, though unlike Kisame they usually look like normal humans in all other respects. And Kisame is the most prominent example because he has far more screen time than all of the others.
  • When Naruto initially taps into his Jinchūriki powers, his teeth — particularly his canine teeth — start changing into fangs.
• Gyro Zeppelli in JoJo's Bizarre Adventure: Steel Ball Run is a rare protagonist example. His teeth are metallic and have "Go! Go! Zeppelli!" engraved on them. Most of the time his teeth are drawn normally, but when he throws a mischievous smile, the engravings can be seen, which can be a little jarring.
• The titular character of Soul Eater and Giriko both have mouths entirely full of pointed teeth, neither of which is ever commented on.
• Emperor Ganishka from Berserk looks like an Indian Santa Claus with a bear trap for a mouth.
  • Protagonist Guts goes into this territory himself whenever he is baring his teeth.

• Moral from Hamatora has shark-like teeth.
• Nanana from Bleach has regular-shaped teeth, but they're colored black and gold (in a checkered pattern).
• Kubera: Despite looking almost entirely human, Yuta actually has rows on rows of teeth in his mouth. We get an even clearer picture when we see Yuta hide Leez in his sura-form mouth to protect her from a hail of energy blasts. After their attacker leaves, Yuta anxiously wants Leez to come out but she's remarkably casual about getting stuffed into a mouth full of sharp, pointed teeth. She even cuts herself while climbing out but manages to keep her reaction to mild surprise/interest, going to show how hard she's trying to show she trusts her friend.
• Yoichi Hiruma from Eyeshield 21 has these, and there's no in-universe explanation for them.
• My Hero Academia:
  • Eijiro Kirishima has shark-like teeth, to fit with how his entire body gets sharp-edged whenever he uses his Hardening quirk.
  • The villain Moonfish really takes the cake as this is his Quirk. Specifically it's known as "Blade-Tooth" and lets him grow and control his teeth, with his preferred usage making LONG branching sharp fangs to stab people and move around with them. Combined with him being a Ax-Crazy death row inmate who may be a I Am a Humanitarian, and you got some very scary teeth.
  • One of All For One's old customers had a monstrous set of teeth as his Quirk. He, however, recieved scorn for this to the point of being disowned by his parents, causing him to seek All For One's aid to remove them in exchange for loyalty.
• Hawk from Goemon Ishikawa's Spray of Blood has large metal teeth that would make Jaws proud. He rarely smiles, but when he does the effect is very intimidating.
  • Chlo, an assassin from Lupin III: Part 5, which is part of the same franchise, has filed teeth that can chew through metal. She even manages to catch Goemon's sword in her mouth.
• Hime Mishiro from Mishiro-san to Yamada-kun has a mouth full of sharp teeth. They aren't pointed out too often, but it's revealed that a fair number of people find them unattractive (alongside her eyes, which combined with her teeth make her look a bit shark-like), and it upsets her when she hears people say it, though her friends don't think so. It's eventually revealed she inherited them from her mother. Presumably, people can just look like that naturally in this universe.
• Helga's mouth in How to Treat a Lady Knight Right looks like a miniature bear trap. This does not in any way detract from her role as a Shrinking Violet.
• Misago from Yokohama Kaidashi Kikou is a mermaid-like being that has a hard time making friends despite being kind, loving and good-natured because she has shark-like teeth. She actually is carnivorous, but the only flesh she eats is fish.
• Hitomi from Hitomi-chan Is Shy with Strangers is drawn with this kind of teeth to emphasize her misleadingly scary face.
• Frederica and Garfiel from Re:Zero have such teeth. Subaru once noted that Frederica would probably be a really pretty woman if she didn't have teeth like that. Both have such teeth because they are hybrids of humans and beastmen. Despite the creepy teeth, both are good guys, even if Garfiel isn't always the nicest.
  • The Gluttony triplets, Lye Batenkaitos, Roy Alphard, and Louis Arneb, who are collectively the Sin Archbishop of Gluttony, all have shark-like teeth.
• The main character of Fire Force, Shinra Kusakabe, has sharp teeth that makes his smiles look far more malicious than they actually are. This is actually a hereditary characteristic, as his mom has similarly sharp teeth.
• ST☆R: Strike it Rich: Ichika is drawn with shark-like teeth to emphasis the fact she is a rude Dirty Cop.
• The 100 Girlfriends Who Really, Really, Really, Really, Really Love You: Rin Baio's teeth are shown to be sharp and pointed, not unlike a shark. This is in stark contrast to her general demeanor of a refined, if sheltered, young girl. Her teeth only really become apparent when her Nightmare Fetishism is triggered, as she smiles widely and sharply at the sight of anything sufficiently violent.

Cody later declares the experience to be even better than chocolate and strawberries.

Most Don Bluth villains, such as Drake, Carface, or Jenner, wear big, toothy grins most of the time and tend to snap their jaws as they speak.

  • When the Mouth of Sauron appears in The Return of the King, his helmet covers up every part of his face except for his mouth, which often grins with elongated, pointy teeth covered in black ichor. Eugh. Special effects trickery was used to enlarge the actor's mouth to make it look even more freaky and uncanny. It is strongly implied that the reason the Mouth's teeth are so horrible is because hundreds of years of repeating Sauron's evil words was enough to rot his mouth and teeth.
