Identification by Dental Records

A crime drama trope. Sometimes a dead body will be so devastated (e.g. burned or decayed beyond recognition) that identifying the victim by their appearance is impossible. The investigators have no choice but to use the victim's dental records to find out their identity.

Dental indentification lets the audience know the death was gruesome without necessarily showing the body. It also adds another layer of complexity to the plot. Was the body really correctly identified? What if the records are missing?

Sometimes the Genre Savvy criminal knows to avert this trope by removing the victim's teeth.

Sometimes in fiction a character has his teeth surgically altered so he can fake his death. Such surgery is easily identifiable in Real Life, at least in modern times, and in most cases the best way to fake a death through dental ID would be to switch the records.

A common trope in police procedurals, medical mysteries, and forensic shows. Identifying bodies from dental records is Truth in Television, but it works a lot better in fiction than in real life. See the Notes.

Anime and Manga

 * In Fullmetal Alchemist, when Roy Mustang is led to believe that Maria Ross assassinated Maes Hughes, he cuts off her escape and incinerates her to the point that the corpse can only be identified in this fashion.
 * Subverted in Higurashi no Naku Koro Ni:
 * In Umineko no Naku Koro Ni,
 * In Loveless, Seimei's body is identified this way after it is mangled beyond recognition before the start of the story.
 * In Veritas, this is how Lightning Tiger's remains are identified after he's burnt to a crisp.

Film

 * The Whole Nine Yards the main character has a Chekhov's Skill: his are a dentist, and can thus can fake deaths by altering the teeth and dental work of corpses to resemble those of living people.
 * Wild Things. Police find some teeth by the beach and use Suzie Toller's dental records to identify them as hers and confirm her death.
 * Earl Talbot Blake fakes his death in Ricochet by switching his dental records with another inmate, and killing said inmate after escaping from prison.

Literature

 * Several Lord Peter Wimsey stories invoke this trope, though the identification is usually subverted.
 * In the short story In the Teeth of the Evidence, the dentist who makes the initial identification is working from written records and is so disturbed by the state of the badly-burned body that he performs only a cursory examination. It's only after the coroner finds hyoscine in the remains that he re-examines the teeth and determines that
 * The Nine Tailors also featured a failed dental identification.
 * Dental identification is also a key plot point in Agatha Christie's novel One, Two, Buckle My Shoe.
 * In Rupert Holmes' novel Swing, a character is killed in a fiery car accident and identified via dental records.
 * Brat Farrar by Josephine Tey discusses this but eventually averts it. The protagonist is impersonating a long-lost heir; it turns out that he doesn't have to deal with matching the heir's dental history, as the dentist who could have recognized him died along with the heir's parents.
 * In the Nancy Drew Files book "Till Death Do Us Part'' a woman plots to kill Nancy's boyfriend Ned Nickerson and pass him off as her husband so she can collect the husband's inheritance. Stealing Ned's dental records was part of her fiendish scheme.
 * Gorky Park. Three bodies are found in Gorky Park, Moscow -- shot and with their faces cut off. Each was also shot in the face, not as a coup-de-grace but to destroy their teeth. However a clue survives in that one of the characters had gutta-percha in his dentalwork (anyone living in the Soviet Union would have stainless steel dentistry) revealing that he's a foreigner.
 * Brotherhood of the Rose by David Morrell. One of the protagonists -- on the run from the CIA -- visits a Mexican dentist and asks to have all his teeth removed. It turns out to be a trap and his surrogate father Elliot recaptures him while he's under the anesthetic. Elliot asks his 'son' why he wanted his teeth removed, and is shocked to find he intended to commit suicide; as his body would never be identified, his surrogate family would think he had successfully escaped, thus being spared the pain of his death.

Live Action TV

 * Frequently on Bones, where they deal with corpses in advanced states of decay and/or dismemberment.
 * Also frequent in Wire in The Blood, where they deal with deeply disturbed people who either frantically mutilate their victims or cold-blooded sociopaths min-maxing their way to maximal bodycount by removing other identifying features from their victims.
 * Referenced on How I Met Your Mother when Barney says that, given the things he knows about Goliath National Bank, he'll never be fired, but that he might one day "wash up on shore with no fingerprints or teeth."
 * CSI: several episodes, being a long running cop show. For example "Bad To The Bone": skeletal remains are identified as Marissa Cleary from her dental records.
 * The Bill Several episodes. For example Season 5, Episode 6: "Life And Death" a man has a drug overdose after confessing to a murder. He is identified by dental records, allowing the police to track down his family.
 * NCIS
 * One episode featured an odd variation: The one suspect in the murder case is said to have burned to death three years ago, and dental records confirm this... but the forensics team, on a hunch, tests the blood type of both the teeth and the corpse, and finds that they don't match. Meaning that the killer faked his own death all those years ago by removing his own teeth and gluing them in the corpse's skull.
 * In another episode, Tony is arrested for murder when he is tied to a bite mark on a dismembered leg via dental impressions.
 * There's an Urban Legend that the reason you're told to adopt the "brace position" or "crash position" in case of a plane crash or emergency landing is to preserve your dental records if you die. This was debunked on QI, and David Mitchell commented that he'd never believed it in the first place, because surely they'd just say, "In the unlikely event of the plane crashing, I think we can all agree you'd like to be identified. Bite down hard on your armrest."
 * Brought up on Its Always Sunny in Philadelphia when Mac and Charlie want to fake their deaths. They leave a few of Charlie's teeth in a car. This is not how it works.
 * Mentioned in an episode of Hustle: a deceased criminal, quoth Morgan, "threw himself under a goods train a week after his release... there was so little left, by the time they scraped him off the track, they had to identify him from dental records". (Their goal is to make it seem like they Never Found the Body, and that he actually faked his death to abscond with the stolen gold.)
 * An episode of Law and Order had them discover skeletal remains where the teeth had been purposely removed by the killer to prevent positive ID.
 * One episode of The Mentalist had a body burned in a car identified by dental records. As it turned out,.
 * In the Grand Finale of House,

Real Life

 * The four Ted Bundy victims found at his Taylor Mountain dump site were identified by dental records -- mainly because all they found were skulls and jawbones.
 * One of the pieces of evidence presented at a trial was bite marks on one of his victims which were compared to Bundy's dental records.
 * In fact, dental records are one of the three methods of positive identification of human remains (the others being nuclear DNA and fingerprints). Dental records are used to identify thousands of people every year in the US, including murder and accident victims, suicides, and even living persons such as Alzheimer's victims who have strayed far from home.

Tabletop Games

 * An interesting subversion of this can be found in most versions of Dungeons and Dragons regarding the spell Speak With Dead. In most cases, the spell required that the corpse's jaw was intact in order to function (basically the caster was briefly animating the corpse for the purpose of answering some questions) so a common practice was to remove the lower jaw of anyone you killed and didn't want blabbing about it later.

Videogames

 * Mentioned in the opening sequence of Eternal Darkness, but the dental records cannot be used (because the victim's head is missing).
 * In Grim Fandango, the computer terminals at the Department of Death scan the user's teeth to give them access, which makes sense seeing as a person's chompers are one of the few identifying physical features one can carry over from the Land of the Living. This is used in a puzzle early on in the game, where Manny has to make a mold so that a local resistance group can make a replica of his teeth and access the Department of Death's computer network.
 * In Rama, Puck identifies the skeleton of this way.
