Dakota Johnson Teeth: Gap Teeth, Myths, and Facts

Short answer

• Dakota Johnson was known for years for a small gap between her two upper front teeth. In dental terms that gap is a diastema. In August 2019, after fans noticed at a film premiere that the gap seemed to be gone, she explained on The Tonight Show Starring Jimmy Fallon that she had not chosen cosmetic treatment to close it. She said she had worn a permanent retainer, glued behind her teeth, since she was 13, that she had been having neck problems, and that her orthodontist removed the retainer to see whether her jaw would expand. It helped, she said, and in her words, her gap closed by itself. She also said she was sad about losing it. That one documented account answers the celebrity question. There is no confirmed public evidence that Johnson had veneers, bonding, or any other cosmetic procedure to close the gap, and claims of that kind online are unconfirmed. Her wider dental history is private, and photographs are not a dental record. For readers with a gap of their own, the dental facts are simpler than the myths suggest. A diastema is common, especially between the upper front teeth, and Cleveland Clinic describes it as a variation of normal dental development in most cases. A stable gap in healthy teeth is usually a cosmetic matter, not a disease. A gap that is new, widening, painful, or paired with gum bleeding, swelling, or loose teeth is different, and a dentist should evaluate it. This article is general information only. It is not a diagnosis or a treatment plan for any individual, including Johnson.

What Is Documented About Dakota Johnson’s Gap

The gap as part of her public smile

Johnson’s front tooth gap was a visible part of her public image as she became widely known as an actor, and entertainment coverage often described it as a signature feature. That is a description of public perception, not dental health. A photograph can show that a space was visible at a given time. It cannot show why it was there, whether the teeth and gums were healthy, or what treatment sat behind the smile. The confirmed record is what she has said herself and what reputable outlets reported at the time. It does not include her dental charts, and the causes and treatments discussed later are about diastema in general, not a reconstruction of her case.

The 2017 Vanity Fair video

In February 2017, Johnson leaned into the public interest with humor. Entertainment coverage of a Vanity Fair video titled around how much she could fit in her gap teeth describes her playfully demonstrating the width of the gap with small objects. It shows one thing only: she was then comfortable treating the gap as a distinctive, even comic, feature rather than as a flaw. It says nothing about her dental health.

What changed in 2019, in her own account

The change was first widely noticed in photographs from the Los Angeles premiere of The Peanut Butter Falcon on August 1, 2019, where her front teeth appeared to meet with no visible gap. Speculation followed, much of it assuming a deliberate cosmetic procedure. Johnson addressed it days later on The Tonight Show Starring Jimmy Fallon, in an appearance reported by W Magazine on August 7, 2019. Her account, quoted in that reporting, was specific. She said: “I had a permanent retainer since I was 13, and it was just glued to the back of my teeth.” She continued that she had been having a lot of neck problems, that her orthodontist decided it would be a good idea to take the retainer off and see whether her jaw expanded, and that the removal helped her. Then she said her gap closed by itself.

Two details correct the usual retelling. First, she presented the closure as unwelcome, not as a makeover: she said she was really sad about it too, and joked that she would appreciate some privacy while she adjusted. Second, she joked that food now got stuck between her front teeth, where before it would slide through the gap, and laughed that the gap would come back with other retainers. These are talk show remarks, delivered partly as comedy. The factual core is narrow: a long worn retainer was removed on her orthodontist’s advice during a period of neck problems, and her front teeth then moved together.

What has not been confirmed

Much online content about celebrity teeth goes further than the evidence. In Johnson’s case, the following are unconfirmed and should not be repeated as fact: that she had veneers, bonding, whitening, or braces as an adult to close the gap; that any named dentist, clinic, or product was involved; that her original gap had a specific cause such as a large frenum or a size mismatch; and that her teeth are in any particular state of health today. She has confirmed none of this, and her 2019 account describes no closing procedure at all.

This pattern is not unique to Johnson. Our companion explainer on celebrity cosmetic dentistry sets out the same three way split, what is known, what is rumored, and what is not verified. If a page states a celebrity procedure as fact without a statement from the person or a treating clinician, treat it as speculation.

What a Diastema Is

A diastema is a space between two teeth. The word is used for a gap anywhere in the mouth, but the most familiar form, and the form Johnson had, is a midline diastema: a space between the two upper front teeth, the central incisors. Gaps vary widely, from a fraction of a millimeter visible only up close to a space noticeable across a room.

Cleveland Clinic makes the central point plainly: most healthcare providers view diastema as a variation of normal dental development, and having a gap does not often have a negative impact on oral health. A diastema describes spacing. It is not a diagnosis of disease. The same word covers a lifelong, stable, healthy gap and a new gap that has appeared because gum disease has loosened teeth. The spacing can look similar in a mirror while the meaning is entirely different, which is why dentists ask about cause and change over time before discussing treatment.

Gaps in children

Gaps are especially common in childhood. The Colgate Oral Care Center notes that many children experience a diastema as their primary, or baby, teeth fall out, and that in most cases these spaces close when the permanent teeth come through. A child’s front tooth gap is therefore usually a stage of development that a dentist monitors at routine visits.

Adults are different. Once the permanent teeth are in place, a stable gap often stays much the same for years. A genuinely new gap in adulthood, or an old gap that is clearly widening, has a cause worth finding.

What Causes a Gap Between Teeth

Dental sources list a consistent set of causes. More than one can apply in the same mouth, and only an examination can say which apply to a particular person.

Tooth size and jaw size do not match

The most common background cause is a size mismatch. If the teeth are small relative to the jaw bone, there is extra room along the arch and spaces can open. If the teeth are large relative to the jaw, crowding is more likely instead. Tooth and jaw size are strongly influenced by inheritance, which is why gaps often run in families, and Cleveland Clinic lists inherited traits, including teeth that are too small, among the usual reasons a person is prone to a gap.

Missing or undersized teeth

A tooth that never formed, was lost, or is much smaller than it should be leaves room that neighboring teeth can drift into. Colgate notes this happens most often with the upper lateral incisors, the teeth beside the two upper front teeth. When a lateral incisor is missing or undersized, sometimes described as peg shaped, the central incisors can keep a space between them.

An oversized labial frenum

The labial frenum is the band of tissue connecting the inside of the upper lip to the gum above the two upper front teeth. Normally it sits clear of the teeth. In some people it is larger, lower, or continues between the two front teeth, where, as both Colgate and Cleveland Clinic explain, it can block the natural closing of the space and hold a midline gap open.

Habits and tongue pressure

Sustained pressure moves teeth slowly. Thumb sucking in childhood tends to pull the front teeth forward, creating or widening gaps. An abnormal swallowing pattern, often called tongue thrust, has a similar effect: the tongue usually presses against the roof of the mouth when swallowing, and if it presses against the front teeth instead, that repeated pressure can push them forward and open spaces, as both Cleveland Clinic and Colgate describe.

Gum disease and bone loss

This is the cause that changes the advice. In advanced gum disease, called periodontitis, infection damages the bone supporting the teeth. Cleveland Clinic describes the result directly: infection erodes the jawbone, causing gaps and loose teeth, and Colgate gives the same account. A gap that arrives this way is a symptom. Closing it cosmetically without treating the gum disease would hide the sign and leave the cause active.

Teeth shifting after orthodontic treatment

Teeth can move when the support holding them changes. Retainers exist because teeth tend to shift after orthodontic movement. Johnson’s 2019 account illustrates the principle: a retainer worn since age 13 was removed, and her front teeth moved together until the gap closed. In reverse, a gap closed with braces or aligners can reopen if a retainer is abandoned. Individual movement varies.

When a Gap Is Purely Cosmetic and When a Dentist Should Evaluate It

The usual case: stable, healthy, and a matter of preference

For many adults, a front tooth gap has been present since adolescence, has not changed, causes no pain, and sits in a mouth with healthy gums and a comfortable bite. Dental guidance treats that gap as a cosmetic feature. Treatment is available if the person wants it, and no treatment is also a complete and reasonable plan. There is no health deadline attached to a stable diastema.

Signs that call for an examination

Book a dental examination rather than a cosmetic consultation alone if any of the following apply:

• The gap is new in adulthood, or an existing gap is widening.
• A tooth feels loose, or several teeth seem to be drifting.
• The gums bleed, look swollen or receded, or there is a persistent bad taste.
• There is pain, sensitivity that does not settle, or difficulty biting or chewing.
• Food packs into the gap and irritates the gum, or cleaning the area has become difficult.
• The gap followed an injury, a lost tooth, or a lost filling or crown.
• Speech has changed, or a child has a gap alongside a strong thumb sucking or tongue thrust habit that is not easing.

Cleveland Clinic draws the same line: if the gap is new or changing size because of a gum infection, gum disease treatment is what is needed. The examination comes first because it separates a spacing preference from a health problem, and treating a cause comes before any discussion of appearance.

Myths and Facts About Gap Teeth

How Gaps Are Closed, in General Terms

This section describes the options dentists discuss in general. It is not a recommendation for any reader, and it is not a claim about Johnson, whose gap closed without any of these procedures according to her own account. Suitability depends on the cause of the gap, its size, the bite, gum health, and the health of the teeth on either side.

Start with the cause, not the product

Every credible path starts with an examination, often with imaging, that answers three questions. Why is the gap there? Are the teeth and gums healthy enough for cosmetic work? Will the force that opened the gap reopen it? Closing a gap without addressing its cause invites the space to return. Readers comparing restorative approaches can read our general explainer on restorative dentistry, which covers crowns, bridges, and restorations in plain terms.

Orthodontics: braces and clear aligners

Orthodontic treatment moves the teeth themselves. Braces use brackets and wires to guide teeth together over time. Clear aligners use a series of removable trays to do the same job in stages. Orthodontics suits wider gaps, gaps within a wider spacing or bite pattern, and people who prefer to keep their natural tooth surfaces intact. The trade off is time, in months rather than a single visit, plus retention afterward. If aligners are part of your thinking, our guide on whether Invisalign is worth it for adults works through the commitment and wear time questions adults ask first.

Bonding

Bonding builds the teeth up rather than moving them. A dentist applies tooth colored resin to the sides of the teeth beside the gap, shapes it so each tooth looks slightly wider, hardens it with a light, and polishes it. For a small gap it can be a conservative option, often completed without removing enamel. Its limits matter: resin can stain and chip more readily than enamel or porcelain and may need repair over time, and bonding does not correct tooth position or the bite. It changes the apparent width of the teeth, suiting some small gaps and not larger or unstable ones.

Veneers

A veneer is a thin shell fitted over the front surface of a tooth. The Journal of the American Dental Association explains that veneers sit over the front, visible part of the tooth, may be used to correct uneven spaces or a diastema, and come in two main kinds: ceramic veneers, made in a laboratory to fit the individual teeth after a small amount of enamel is removed from the front and sides, and resin based composite veneers, generally placed in one appointment with the material bonded and sculpted directly on the tooth. The same source sets out the key cautions: teeth must be healthy and free of decay and active gum disease first, the process is not reversible once enamel is removed, and people who clench or grind their teeth are not good candidates because thin veneers may chip, break, or peel. A veneer plan makes the two front teeth look wider so the space disappears, a long term commitment on otherwise healthy teeth, which is why dentists usually discuss bonding and orthodontics first for a small, simple gap.

Frenum and gum treatment, where the cause requires it

If an oversized labial frenum holds the front teeth apart, a dentist may refer the patient for a frenectomy, a procedure that reduces or repositions the frenum. Colgate describes referral to a periodontist for this and notes that, in a younger child, the space may close on its own afterward. In adults it is usually one part of a plan, and orthodontic closure may still be needed. If gum disease caused or widened the gap, periodontal treatment comes first, to control the infection and stabilize the supporting bone, before any cosmetic step. Where a gap exists because a tooth is missing, the discussion is different again: replacing that tooth, with an implant, a bridge, or a partial denture in general terms, rather than moving or widening the others.

Keeping a Gap: A Valid Choice

Keeping a gap is a normal outcome of a dental discussion, not a failure to act. Many people like how their gap looks. Others weigh months of orthodontics, or a permanent restoration on healthy enamel, against a feature that causes no pain or health problem, and decide the feature wins. Johnson’s remarks point the same way: she did not campaign to close her gap, and she missed it when it closed. That is one person’s preference, not advice for anyone else, but it breaks the assumption that every gap is waiting to be fixed.

If you keep a gap, keep the routine that makes keeping it safe: regular dental visits so the dentist can confirm the gap is stable and the gums healthy, daily cleaning between the teeth, and an earlier return if anything changes. A kept gap that is monitored is good dentistry. A gap that is never examined is a guess.

Looking After Teeth When You Have a Gap

Daily care for a diastema is mostly the familiar routine, done carefully. Brush twice a day with fluoride toothpaste, and clean between the teeth once a day with floss or another interdental cleaner your dentist recommends, working gently around the wider front space rather than skipping it because it feels open. The gum there can be a little more exposed, so gentle technique matters more than force.

Pay attention to food trapping. A gap that occasionally catches a fibrous strand is unremarkable. A gap that packs food at most meals, leaves the gum sore, or bleeds when cleaned deserves a mention at your next visit, and an earlier visit if soreness persists. If you have had a gap closed, care for any retainer as instructed, and tell your orthodontist if a fixed retainer feels loose or a removable one no longer fits.

Questions to Ask a Dentist About Your Own Gap

Ask what is causing your gap, whether it is stable and how change would be detected, whether your gums and supporting bone are healthy, and whether any treatment in your case is needed for health or is purely cosmetic. If you wanted it closed, ask which options fit a gap of this size and cause, what each involves in time, visits, maintenance, and retention, and what happens if you do nothing except keep routine visits. Take time afterward: a stable gap carries no urgency, and the decision should rest on examination findings and your own preference.

Frequently Asked Questions

What is Dakota Johnson’s gap tooth?

It was a small space between her two upper front teeth, known in dentistry as a midline diastema. It was a visible part of her public smile for years and was widely discussed in entertainment coverage. This article does not diagnose why she had it.

What happened to Dakota Johnson’s tooth gap?

By her own account on The Tonight Show Starring Jimmy Fallon in August 2019, the gap closed on its own after her orthodontist removed a permanent retainer she had worn since she was 13. She said it was removed because she had been having neck problems and her orthodontist wanted to see whether her jaw would expand, and that the removal helped her. She said she was sad the gap had closed.

Did Dakota Johnson get veneers?

That claim is unconfirmed. She has not confirmed veneers, bonding, or any cosmetic procedure to close the gap, and her 2019 account attributes the closure to retainer removal and natural tooth movement. Online claims naming a procedure, clinic, or product are speculation unless she or a treating clinician confirms them.

Does a tooth gap need to be fixed?

Not always. A stable gap in healthy teeth is usually cosmetic and may need no treatment. A gap that is new, widening, painful, or paired with bleeding or swollen gums, loose teeth, or difficulty eating should be assessed by a dentist, because the cause may need treatment.

Can a gap be closed without veneers?

Yes, in many cases. Depending on cause and size, dentists discuss orthodontics with braces or clear aligners, which move the teeth together, and bonding, which widens the teeth beside a small gap with resin. A frenum procedure or gum disease treatment may also be part of the plan. An examination determines which options fit.

Is a gap a sign of bad teeth?

No. A diastema can occur in otherwise healthy teeth and often reflects inherited tooth and jaw size. It becomes a health concern when linked to gum disease, a missing tooth, bite problems, or change over time, which is why a new or changing gap deserves an examination.

Can a tooth gap close on its own?

In children, yes, commonly. Many gaps appear as baby teeth fall out and close when the permanent teeth come through. In adults, a long standing gap usually stays stable, although teeth can move when the forces holding them change, as Johnson described after her retainer was removed. Adult tooth movement either way is a reason to talk to a dentist.
