A character smiles, and it is revealed that his or her 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 PrimalFear 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.

!!Examples:

[[foldercontrol]]

[[folder:Anime and Manga]]
* Arlong and Hody Jones from ''Manga/OnePiece''. 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 [[IdiotHero Luffy]]). Mostly PlayedForLaughs.
** The half-mermaid Charlotte Praliné also has these, and it's justified as her father is said to have been a hammerhead shark merman.
* Viral from ''Anime/TengenToppaGurrenLagann'' is a shark-type Beastman with feline genetics, and has the choppers to match.
* ''Manga/{{Naruto}}'''s Kisame Hoshigaki has pointed teeth, among other shark-like characteristics.
* Grell Sutcliff from ''Manga/BlackButler''.
* Gyro Zeppelli in ''[[Manga/JoJosBizarreAdventure Steel Ball Run]]'' is a rare good guy 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 ''Manga/SoulEater'' and Giriko both have mouths entirely full of pointed teeth, [[UnusuallyUninterestingSight neither of which is ever commented on.]]
* Emperor Ganishka from ''{{Manga/Berserk}}'' looks like an Indian Santa Claus with a bear trap for a mouth.
** Protagonist Guts goes into this territory himself [[SlasherSmile whenever he is]] [[TechnicallyASmile baring his teeth.]]
* Rin Matsuoka from ''Anime/{{Free}}'' has shark teeth for some reason (as a child he only had CuteLittleFangs). It's because his representative animal in the series is a shark, but in universe no explanation is given.
* Moral from ''Anime/{{Hamatora}}'' has shark-like teeth.
* Nanana from ''Manga/{{Bleach}}'' has regular-shaped teeth, but they're colored black and gold (in a checkered pattern).
* ''Webcomic/{{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 [[spoiler: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 ''Manga/Eyeshield21'' has these, and there's no in-universe explanation for them.
* Kirishima Eijiro from ''Manga/MyHeroAcademia'' has these

[[folder:Comicbooks]]
* In ''ComicBook/BatmanTheDarkKnightReturns'' the leader of the Mutant gang has filed his teeth to points. He nearly bites a chunk out of Batman's shoulder during their first fight, and later uses them to rip out the mayor's throat.
* This trope is also played with regarding SelfDemonstrating/TheJoker and his teeth - depending on the artist, his teeth can be a nasty yellowed color (implying he probably doesn't brush them), drawn unevenly, drawn longer than or as being more prominent than normal, [[MoreTeethThanTheOsmondFamily share space with FAR too many teeth for a normal human being]], or a combination of more than one of these.
* Gargamel in ''ComicBook/TheSmurfs'' mostly appears with only one top tooth in his mouth in most comic book and cartoon show appearances.
* ComicBook/SpiderMan villain [[EvilAlbino Tombstone]] has pointed teeth, because he purposely filed them that way to make himself look scary.
** The Power Man and Iron Fist series demonstrates in a flashback that he did this with other criminals as a part of conception for [[GangOfHats The Fang Gang]], following the example of a piranha like mutate on their team.

[[folder: Fan Works]]
* Subverted in ''Fanfic/TheKeysStandAlone: The Soft World'' by Mattagandas Bullslayer. He's got creepy pointed teeth that make the four uncomfortable, but they also feel he's being straight with them. He ultimately does turn out to be one of the few reasonably honest people they meet—not that it matters, since circumstances preclude their working with him.

[[folder:Films -- Animated]]
* Sharpteeth in ''WesternAnimation/TheLandBeforeTime''.
* Scar, at least once, in ''Disney/TheLionKing''. The hyenas too. "Yes our teeth and ambitions are bared!"
* Jafar from ''Disney/{{Aladdin}}'', in his old man disguise.
* In ''Disney/BeautyAndTheBeast''
** While the servants instruct Beast on making a good impression for Belle, Mrs. Potts suggests that he smile. The Beast tries to, but we see TheUnsmile showing MoreTeethThanTheOsmondFamily.
** While Maurice is describing the Beast to the villagers, one of them asks "With a long, ugly snout?" and puts a glass mug over his mouth, which magnifies his crooked teeth.

[[folder:Films -- Live-Action]]
* ''Film/JamesBond'':
** Jaws from ''Film/TheSpyWhoLovedMe'' and ''Film/{{Moonraker}}''.
** Silva from ''Film/{{Skyfall}}''. [[spoiler:His dentures hide the fact that his real teeth have been [[BodyHorror reduced to rotten nubs]] as a result of a defective CyanidePill.]]
* Jack has one for a moment in ''Film/FightClub'', when he smiles at a fellow coworker during a meeting and his mouth is a bloody mess.
* ''Film/ShanghaiKnights'': During a chase scene, Roy runs into a demure-looking street vendor and starts putting the moves on her... then she smiles, revealing hideous rotting BritishTeeth. He understandably panics.
* In ''Film/{{Coneheads}}'', the titular characters have this until they fix their teeth to blend better amongst humans: not only are their teeth shark-like, when they open their mouth wide, it shows endless rows of them.
* Seth Brundle in Creator/DavidCronenberg's remake ''Film/TheFly1986'' slowly loses his teeth as the transformation progresses, making him look more inhuman and threatening.
* ''Film/TheLordOfTheRings'':
** When the MouthOfSauron appears, 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.
** Less pronounced, but if his slightly insulting behavior at the beginning of the first movie hasn't suggested to you that [[spoiler:Saruman]] might be a bad guy, his rather filthy teeth (compared to Gandalf's fairly healthy ones) really ought to have.
*** They are, in fact, Creator/ChristopherLee's [[BritishTeeth natural set]], but they are made more pronounced by making his otherwise white beard dark around his mouth.
* Winslow Leach in ''Film/PhantomOfTheParadise'' had his teeth replaced with sharp stainless steel teeth while he was in prison.
* The Film/DCExtendedUniverse version of the Joker has unnerving metallic prostheses for teeth and we get to see them quite a lot thanks to a nigh permanent SlasherSmile.
** Killer Croc has jagged, pointy crocodile teeth.
* In ''Film/SleepyHollow'', the Hessian who would become the Headless Horseman has a mouthful of almost shark-like teeth, making an already vicious killer even more menacing.

[[folder:Literature]]
* Pennywise in ''Literature/{{It}}'' can morph his teeth into a fanged maw.
** Also in ''Literature/{{IT}}'', Henry Bowers has "rotting, Maine back-woods teeth," described like the headstones in a graveyard gone to disrepair.
** ''Literature/ArtemisFowl''
** [[LoveableRogue Mulch Diggums]], like all dwarves in the setting, has some very large and intimidating teeth, described as looking like enamel tombstones. At one point, he intimidates a human mobster by giving him a good look at them.
** Arno Blunt, TheDragon from ''The Eternity Code''. After getting his teeth shattered early on in the book, he gets a number of interesting - and somewhat disturbing - prostheses.
* In Literature/{{Discworld}}, Cohen the Barbarian has dentures made out of diamonds. In the Disc, diamond teeth are associated with trolls, so anyone who sees Cohen's is understandably disturbed.
* Apparently Randall Flagg in ''Literature/TheStand''. "There were worse things than death. There were teeth." (illustrated rather well with a big lamprey-mouth sketch in the comic.)
* Every time Vlad in ''Literature/CountAndCountess'' is about to take a bite out of someone, he grins. The glimpse of artificially sharpened teeth serves as the victim's first and last warning.
* ''Literature/RedDragon'' : The Tooth Fairy, for obvious reasons. Francis Dolarhyde likes to bite his victims, using a plate from his dead grandmother, who had terrible snaggle-teeth.
* ''And I Darken'' 's Lada (a female imagining of Vlad the Impaler) has small, sharp teeth that she uses [[ManBitesMan in her fighting]].
** another, different set of scary teeth, in the sequel ''Now I Rise'', are those of Princess Vasilisa, Lada's mother: her teeth are eerily shattered from years of abuse at the hands of Lada's father.

[[folder:Music]]
* The subject of Music/WeirdAlYankovic's song "Toothless People" from ''Polka Party!''
* Music/TheRollingStones' "Jumpin' Jack Flash" has the line "I was raised by a toothless bearded hag."
[[/folder]]

[[folder:Music Videos]]
* One of the last mouth close-up shots of the Music/WeirdAlYankovic's "Bedrock Anthem" (a parody of Music/ Music/RedHotChiliPeppers' "Give It Away") has dinosaur teeth. A memorable, and hilarious left-field gross-out moment. Al also has a scary set of teeth in the latter end of the video for "I Love Rocky Road".
* [[{{Mascot}} The Guy]] of ''Music/{{Disturbed}}'' has this and GlowingEyesOfDoom as his trademark appearance.
[[/folder]]

[[folder:Video Games]]
* ''VideoGame/KillerInstinct'' has Hisako, the spirit of a child who died protecting her village hundreds of years ago. She can open her mouth to inhuman lengths, but doing so also reveals a bunch of monstrous teeth in said mouth.
* In ''VideoGame/TheLegendOfZeldaBreathOfTheWild'', the [[FishPeople Zora]] all have sharp, carnivorous teeth, but they're generally nice and unintimidating people, with Prince Sidon's teeth in particular being very sharp and shark-like but veering more toward CuteLittleFangs thanks to his NiceGuy personality and friendly TwinkleSmile. It's played more straight with the elderly royal adviser Muzu, whose teeth are more spaced out due to age in a way that gives them an appearance similar to an angler fish's, and who starts off with a brusque personality and an [[FantasticRacism intense prejudice against Hylians]].
* In ''Franchise/TheElderScrolls'', the [[OurElvesAreDifferent Bosmer (Wood Elves)]] within their homeland of Valenwood are bound by the Green Pact, a deal their ancestors struck with the forest's patron deity promising to never harm the plant life within. As a result, they live on an almost exclusively carnivorous diet, including [[ImAHumanitarian other sentient races]] under certain circumstances. As a result, some of the "less civilized" Bosmer who still live deep within the forests have been known to sharpen their teeth into points.
[[/folder]]

[[folder:Web Comics]]
* ''Webcomic/PennyArcade'' combines it with GrossUpCloseUp to illustrate Gabe's [[http://www.penny-arcade.com/comic/2011/05/18/the-maw less-than-stellar mouth hygiene]] (how he doesn't realize he has a rabid badger living inside his mouth, we may never know).
* № 4 from ''Webcomic/{{Hellp}}'' with his shark-like teeth is a non-villainous example.
* ''Webcomic/TheInexplicableAdventuresOfBob--'' "[[http://bobadventures.comicgenesis.com/d/20080401.html Hey!]] [[EverythingsWorseWithBears A bear!]] [[FearlessFool He's smiling!]]"
* ''Webcomic/TheOrderOfTheStick'' features [[OurGoblinsAreDifferent goblinoids]] with tusks protruding from their lower jaw, and fangs visible when they open their mouth. In fact, we see that ALL their teeth are sharp, such as when goblin cleric [[DragonInChief Redcloak]] [[http://www.giantitp.com/comics/oots0901.html shows off more chompers]].
[[/folder]]

[[folder:Western Animation]]
* TheGrinch.
* Ren in ''WesternAnimation/RenAndStimpy''. Especially in "Ren's Toothache", where he refuses to brush his teeth and they eventually rot and fall off.
* In both ''WesternAnimation/TimeSquad'' and ''Film/HudsonHawk'', this is why Leonardo da Vinci ends up painting the Mona Lisa with a closed-mouth smile.
* In ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' [[MadGod Nightmare Moon]] has [[FangsAreEvil fangs]]...which tend to [[CaptainObvious look slightly creepy]] on a horse.
* [[spoiler: The Terras]] in {{WesternAnimation/Motorcity}}.
* ''WesternAnimation/TheSmurfsTheLegendOfSmurfyHollow'' gives us a nice close-up view of the few teeth that are left in Gargamel's mouth.
* SelfDemonstrating/TheJoker, as mentioned above, got these in ''WesternAnimation/TheBatman'', which gave him a gaping mouthful of bright yellow teeth with jigsaw-like protrusions and holes, causing them to slot together in a highly unnatural fashion.
** The same series also gives these to Oswald Cobblepot, the Penguin, with a frankly shark-like array of jagged, pointed fangs.
