When you search for “Billie Eilish teeth,” you are not simply looking for gossip about a pop star’s smile. You are looking at one of the most fascinating, well-documented, and honestly inspiring dental journeys in modern celebrity culture. Unlike many artists who quietly disappear and resurface with a dramatically different smile, Billie Eilish went through her transformation almost entirely in public view, step by step, year by year, from a teenager in braces to a Grammy-winning adult with a radiant and natural-looking set of teeth. This detailed review covers every phase of that journey, examines what procedures she likely underwent based on observable evidence, and answers all the questions fans and dental patients consistently ask.
Who Is Billie Eilish? A Brief Look at the Person Behind the Smile
Before diving into the dental details, it is worth understanding who Billie Eilish actually is and why her appearance matters so much to so many people. Born Billie Eilish Pirate Baird O’Connell on December 18, 2001, in Los Angeles, California, she is currently 24 years old (as of early 2026). She was homeschooled alongside her older brother Finneas O’Connell, who later became her primary collaborator and producer. Their parents, both working in the entertainment industry, cultivated a creative household that pushed the siblings toward music from very early ages.
Billie began playing the ukulele at age six and joined the Los Angeles Children’s Chorus at eight. The real turning point came in 2015 when Finneas wrote a song called “Ocean Eyes” for his band but decided to record it with Billie instead. He uploaded it to SoundCloud for her dance teacher, and the track went viral almost overnight. Record labels came calling. By 2017, she had released her debut EP Don’t Smile at Me, and by 2019, her debut album When We All Fall Asleep, Where Do We Go? dominated global charts and made her a cultural phenomenon.
Her accolades are staggering for someone her age. She won all four major Grammy categories, Record of the Year, Album of the Year, Song of the Year, and Best New Artist, in a single night in 2020, making her the youngest artist in Grammy history to accomplish this feat, and only the second artist ever after Christopher Cross. She went on to win two Academy Awards, the first for “No Time to Die” from the James Bond franchise and the second for “What Was I Made For?” from the 2023 Barbie film. She has accumulated 10 Grammy wins in total, two Oscars, and over 180 awards across her career. Billboard ranked her at number 15 on its 2025 “Top 100 Women Artists of the 21st Century” list. She is, without question, one of the most influential artists of her generation.
What makes her relevant to a dental discussion is this: throughout her meteoric rise, fans watched her teeth change in real time. They watched a teenager with crooked, slightly misaligned teeth gradually develop one of the most photographed smiles in the entertainment world. And, crucially, she never tried to hide the process. In fact, she embraced it.
Billie Eilish Teeth in 2017: What Did Her Natural Smile Look Like?
If you go back to early photographs and interview footage from 2017, when Billie was 15 and just beginning to attract mainstream attention, you see a very different smile compared to what she has today. Her teeth were natural and unmodified: slightly uneven, with a noticeable gap between her upper central incisors, and mild misalignment in her lateral incisors. Her canines were slightly more pronounced than they are now. The color was natural, meaning off-white rather than the bright, luminous white seen in her more recent appearances.
This natural, imperfect smile was very much in keeping with her brand at the time. Billie Eilish was the anti-pop-star: she wore oversized hoodies, kept her aesthetics raw and unpolished, and deliberately avoided the kind of corporate grooming that defined many of her peers. Her smile fit that image. It was real, relatable, and unpretentious. Young fans loved her partly because she did not look airbrushed or surgically perfected the way many industry products do.
From a purely clinical standpoint, her dental presentation in 2017 showed mild crowding in the lower anterior teeth, a slight diastema between the upper centrals, and a midline that was not perfectly centered. None of these are serious clinical issues from a health perspective, but they are exactly the kind of aesthetic concerns that many people address through orthodontic or cosmetic treatment.
Billie Eilish Teeth in 2020: The Invisalign Phase Becomes Public
By 2019 and into 2020, observant fans and dental professionals began noticing small plastic attachments, known as buttons, on Billie’s teeth in close-up photographs and concert footage. These buttons are small dots of composite resin bonded to the tooth surface that help clear aligners grip the teeth and apply precise directional forces during movement. Their presence was a strong visual indicator that she was undergoing Invisalign treatment or another brand of clear aligner therapy.
What made this particularly noteworthy was that Billie did not hide it. Rather than avoiding close-up camera angles or refusing to smile, she continued performing, doing interviews, and appearing at award ceremonies with her aligners and buttons visible to anyone paying close attention. She even appeared in her own music video for “Bad Guy” with her aligners in place. This became a quietly powerful message to millions of young fans: getting orthodontic treatment is not something to be embarrassed about.
Clear aligner therapy such as Invisalign works by using a series of custom-fabricated, nearly invisible plastic trays, each worn for approximately one to two weeks, that gradually shift teeth into a target position programmed by the treating orthodontist using 3D digital planning software. The attachments (buttons) she visibly had on her teeth are placed strategically to allow movements that the aligners alone cannot easily achieve, such as rotation, torque, or extrusion. Billie reportedly wore her Invisalign aligners for approximately a year and a half, which is consistent with the level of correction she appeared to need: moderate rather than severe.
The results of this phase were visible by 2020 and 2021. The gap between her central incisors had closed significantly. Her lower anterior crowding had been resolved. Her midline was more centered. Her canines had been brought into better proportion with the rest of her smile arc. The overall alignment was dramatically improved, and her smile had become noticeably more symmetrical.
Billie Eilish Teeth in 2022: The Refinement Phase and Possible Bonding
The year 2022 marked another visible evolution in Billie Eilish’s smile. By this point, the buttons were gone, suggesting her active aligner treatment had concluded, likely followed by a period of wearing retainers. However, dental observers and cosmetic dentists who analyzed her high-resolution photographs noted that the transformation appeared to go beyond what alignment alone could achieve.
Specifically, the shape of her teeth looked more uniform and proportionate. In orthodontic treatment, straightening the teeth improves their position relative to each other, but it does not change the actual shape of individual teeth. If a lateral incisor is slightly smaller or a central incisor has an irregular edge, these issues remain after alignment. The photographs from 2022 onwards suggest Billie may have had composite bonding performed in addition to her orthodontic work.
Composite bonding is a minimally invasive procedure in which a tooth-colored resin material is sculpted directly onto the tooth surface to improve its shape, size, or surface texture. It does not require significant tooth reduction, meaning it preserves the natural tooth structure. For a young woman in her early twenties who is concerned about maintaining a natural appearance, composite bonding would be a logical choice to address any remaining shape irregularities after completing orthodontic treatment. The results from this period show teeth that are well-proportioned, evenly shaped, and aesthetically harmonious without looking overly manufactured or artificial.
Billie Eilish Teeth in 2025: The Current State of Her Smile
By 2025, Billie Eilish’s smile was drawing consistent praise from cosmetic dentistry professionals and fans alike. Her most recent appearances at award ceremonies, music video shoots, and her Hit Me Hard and Soft world tour show a smile that is straight, symmetrical, proportionate, and bright, without crossing into the territory of unnaturally white or overcrowded veneers that characterize the overdone celebrity smile.
Her upper central incisors are well-proportioned relative to her face: not overly wide, not disproportionately tall. The lateral incisors complement them naturally. The canines provide appropriate definition without appearing too sharp or too reduced. Her lower teeth are cleanly aligned with no visible crowding. The gum line appears healthy, with no signs of recession or inflammation. The color is a natural bright white, consistent with professional whitening rather than the hyper-bleached appearance of zirconia crowns or heavily opaque veneers.
This is, genuinely, an excellent outcome. Not because it is perfect by some artificial standard, but because it looks entirely like her. Her smile in 2025 feels authentic to her face, her personality, and her brand. It has clearly been refined and improved by skilled dental professionals, but it has not been erased and replaced with something generic.
Did Billie Eilish Get Veneers?
This is probably the single most searched question related to Billie Eilish’s dental transformation, and the answer requires some nuance. Based on available visual evidence, it appears unlikely that Billie Eilish has porcelain veneers in the traditional sense, at least not as her primary treatment. Here is why that assessment makes clinical sense.
Porcelain veneers involve permanently removing a thin layer of enamel from the front surface of the tooth, which is an irreversible process. The veneer is then bonded over the prepared tooth. The results are excellent in terms of color, shape, and longevity, but the process commits the patient to veneers for life, since the natural enamel cannot be restored. For a young woman who came up in the industry as an authenticity-driven artist and who underwent a natural, gradual orthodontic transformation rather than an overnight makeover, choosing veneers would have been inconsistent with her general approach.
The photographic evidence supports this interpretation. Her teeth do not show the high-opacity, flat color uniformity that typically characterizes porcelain veneers. They retain translucency at the incisal edges. They have slight natural variation in shade depth. These characteristics are consistent with well-whitened and possibly composite-bonded natural teeth rather than veneer-covered ones. Many dental professionals who have publicly commented on her smile have reached similar conclusions.
That said, it is technically possible that she has had minimal-prep or no-prep veneers applied to some teeth, which involve very little or no enamel reduction. Without access to her dental records, certainty is impossible. What can be said with confidence is that if she does have any veneers, they are excellent quality and expertly calibrated to look natural rather than artificial.
Did Billie Eilish Wear Braces?
Traditional metal or ceramic bracket braces: almost certainly not, or at least not in any detectable phase of her public career. The orthodontic treatment visible in her photographs from 2019 to 2021 is consistent exclusively with clear aligner therapy, specifically the kind using small composite buttons for attachments. No bracket-and-wire hardware was ever observed in images from this period.
It is theoretically possible she wore traditional braces in early adolescence, before her public career, but there is no photographic evidence to support this. What is documented is her clear aligner journey, which multiple dentists who have commented publicly, including prominent cosmetic dentist Dr. Rhona Eskander, have identified as Invisalign-type treatment.
Billie Eilish and Diamond Grillz: The Temporary Fashion Statement
While discussing Billie Eilish’s teeth, it is worth addressing the periodic appearance of decorative dental accessories in some of her stylized photoshoots and editorial appearances. Grillz, removable gold or jeweled dental coverings, have appeared in certain images associated with her more avant-garde visual projects. These are cosmetic accessories, not permanent dental work, and are completely removable. They are frequently used in music video styling and editorial photography as fashion statements rather than representing any permanent modification to her teeth.
It is important not to confuse these fashion accessories with actual dental treatment. The existence of styled grillz in certain images does not mean Billie Eilish has modified her actual teeth with gold or diamond inlays. Her underlying teeth, as consistently visible in non-styled appearances, are natural, well-aligned, and unmodified by decorative metalwork.
Are There Any Signs of Tooth Decay or Dental Health Concerns?
Analyzing the available photographic evidence from multiple angles and over multiple years, there are no visible signs of active tooth decay, significant enamel erosion, or gum disease in Billie Eilish’s teeth. Her gum tissue appears healthy with a consistent, pink, firm appearance. There are no visible dark spots, staining patterns consistent with caries, or areas of enamel breakdown that would indicate serious decay.
This is noteworthy because young people, particularly those under the sustained pressure of touring, recording, and public life, sometimes develop dental health issues related to high-sugar diets, irregular sleep and eating schedules, stress-related teeth grinding (bruxism), or infrequent professional care. None of these warning signs are apparent in her visible dental presentations.
It should be said honestly: neither this review nor any observer can definitively assess someone’s dental health from photographs alone. Interproximal decay (decay between teeth), early-stage gum disease, or hairline cracks in enamel are not visible to the naked eye. Only a clinical examination with X-rays and professional probing can fully assess dental health. But based on observable evidence, her smile shows no red flags.
What Procedures Has Billie Eilish Most Likely Undergone? A Clinical Summary
Drawing together the photographic evidence, professional commentary, and timeline analysis, the most clinically coherent reconstruction of Billie Eilish’s dental journey looks like this. Between approximately 2019 and 2021, she underwent clear aligner orthodontic therapy, most likely Invisalign, to address her diastema (gap), mild crowding, and midline discrepancy. This phase was publicly visible through the presence of composite attachment buttons on her teeth. The treatment appears to have lasted approximately 18 months.
Following the completion of active aligner treatment, likely sometime in 2021, she would have transitioned to a retention phase, wearing retainers to maintain the new position of her teeth. At some point around 2021 to 2022, she appears to have had professional teeth whitening performed, as the color of her teeth became noticeably brighter without the artificiality of porcelain work. Additionally, some form of shape refinement, most consistent with composite bonding rather than veneer preparation, appears to have been applied to create more harmonious proportions in her anterior teeth.
This combination of orthodontics, whitening, and conservative bonding represents an excellent and sensible approach to cosmetic enhancement. It is minimally invasive, preserves natural tooth structure, is appropriate for a young patient, and produces results that enhance natural features rather than replacing them.
Billie Eilish’s Smile vs. a Typical Hollywood Veneer Smile: The Key Difference
To truly appreciate what makes Billie Eilish’s dental transformation clinically admirable, it helps to compare it with what a more aggressive Hollywood smile overhaul looks like. The classic over-treated celebrity smile typically shows excessive uniformity: every tooth the same length, the same width, the same flat opaque white, with no translucency, no incisal variation, and no individual character. This is the look you get when 10 to 20 teeth are all prepared for full porcelain veneers and given a dramatic shade lift. It is immediately recognizable and, to many observers, looks unnatural.
Billie Eilish’s smile avoids all of this. Her teeth have natural slight variations in color depth, with translucency at the incisal edges. They are not all precisely the same length. Her midline is well-centered but not robotically perfect. Her gum line shows natural scalloping rather than an artificially even contour. All of these small imperfections, to use an inadequate word, are actually the features that make her smile look genuine and beautiful. It is the kind of result that skilled cosmetic dentists describe as biomimetic: imitating the aesthetics of healthy natural teeth while correcting functional and aesthetic problems.
This is worth emphasizing for anyone considering their own dental treatment: the most sophisticated cosmetic dentistry is not the most dramatic. It is the kind that makes people say “you look great” rather than “did you get veneers?”
Billie Eilish’s Dental Arch and Facial Harmony
One element of her transformation that rarely gets discussed is the relationship between her dental arch and her overall facial proportions. Orthodontic treatment does not only improve the aesthetics of the teeth themselves; it also changes the way the teeth support the lips and define the lower third of the face. When anterior teeth are properly positioned and the arch form is correct, the lips rest more naturally, the smile arc follows the curve of the lower lip more harmoniously, and the overall facial profile improves.
In Billie Eilish’s case, the closure of her diastema and the correction of her arch alignment have had a subtly positive effect on how her upper lip falls. The slight gap in her earlier photographs created a minor shadow at the center of her smile that is absent in more recent images. The corrected alignment allows light to reflect more evenly across the incisal edges, giving her smile a brighter, more dimensional appearance even under varying lighting conditions, including the intense stage lighting of her world tours.
Before and After: A Year-by-Year Photographic Analysis
Looking at the documented photographic record from 2017 through 2025 tells a clear and coherent story. In 2017, a teenager with a natural, slightly irregular smile. By 2019 to 2020, clear aligner hardware visible, with buttons on the upper and lower teeth, but the alignment actively improving. By 2021, buttons gone, gap closed, alignment noticeably improved, smile brighter. In 2022, further refinement of tooth shape and color, suggesting the completion of a full cosmetic protocol that began with orthodontics and ended with finishing touches. By 2023 and 2024, a fully mature, natural-looking enhanced smile appearing consistently across all contexts, red carpets, stage performances, editorial photographs, and candid shots. In 2025, the most polished version of her smile, with no visible signs of over-treatment, decay, or age-related change.
The consistency of her smile across different contexts in recent years is itself a positive indicator. Poorly executed cosmetic work tends to look different under different lighting conditions. Veneers that are too opaque look unnaturally white in daylight and strangely flat in stage lighting. Composite bonding that is not properly polished can absorb staining quickly. The fact that Billie’s smile looks equally good in paparazzi daylight shots and high-resolution stage photography suggests the work was executed by highly skilled clinicians using quality materials.
What Can Patients Learn From Billie Eilish’s Dental Journey?
Beyond the celebrity fascination, there are genuine lessons in Billie Eilish’s dental story that apply to real patients considering their own smile improvements. The most important is that conservative, staged treatment planning often produces better long-term outcomes than rushing to the most dramatic solution. She did not jump straight to 20 veneers at age 17. She underwent orthodontics first, allowing her teeth to reach their optimal position before any further cosmetic work. This sequencing matters enormously.
Orthodontics before cosmetics is a clinical principle followed by the best smile design practitioners worldwide. When veneers or bonding are placed on misaligned teeth, the results are always compromised. The shape and position of the underlying tooth determine how light interacts with the restoration. Straightening first gives the cosmetic clinician the best possible canvas to work on. Billie Eilish’s treatment, whether by design or good fortune, followed this principle exactly.
The second lesson is that natural-looking results require both clinical skill and thoughtful design. Choosing a clinician who understands facial aesthetics, smile design principles, and the optical behavior of dental materials, not just one who can technically place a veneer, makes an enormous difference in the final result.
The third lesson is about timing and patience. Billie’s transformation took approximately three to four years from the beginning of her visible orthodontic treatment to the polished smile she has today. Rushed cosmetic dentistry often cuts corners in ways that lead to problems down the road. The patience to complete each phase properly is an investment in a lasting result.

Billie Eilish’s Front Teeth: A Closer Look at Her Central Incisors
Dental analysis of public figures often focuses on the front six upper teeth, the “social six,” which are the teeth most visible when smiling. In Billie Eilish’s case, the upper central incisors are the key teeth that anchor the aesthetics of her entire smile. Looking at high-resolution images from 2023 onward, her centrals appear to have a width-to-length ratio in the range of 0.75 to 0.80, which dental aesthetics textbooks identify as the ideal proportion for upper central incisors. This ratio gives the teeth a naturally tall, well-proportioned appearance without looking blocky or stubby.
The incisal edges of her centrals show subtle translucency rather than the flat, opaque appearance of thick porcelain veneers. This strongly suggests that the teeth are either natural with composite additions at the edges, or that if any veneer-type restoration is present, it is of the minimal-prep variety that preserves the existing incisal translucency. The interproximal contacts (the points where adjacent teeth touch each other) appear tight and well-positioned, consistent with properly retained orthodontic outcomes.
Her lateral incisors are appropriately sized at roughly 70 to 75 percent of the width of the centrals, following natural dental proportioning rules. Her canines provide the appropriate definition at the corners of her smile, giving it character without appearing aggressive. The overall arc of her smile follows the curve of her lower lip in full smile mode, which dental aestheticians describe as a “consonant smile arc,” considered one of the most aesthetically pleasing configurations possible.
The Role of Teeth Whitening in Billie Eilish’s Transformation
Teeth whitening deserves its own section because it is one of the most underappreciated elements of smile transformation, and it appears to be a significant factor in Billie’s case. Professional teeth whitening, whether in-office bleaching using high-concentration peroxide gels with light or laser activation, or take-home custom tray bleaching, can dramatically improve the brightness and perceived cleanliness of a smile without any physical alteration to tooth structure.
Comparing her 2017 images to her 2023 and 2025 appearances, the color shift is notable. Her earlier teeth showed natural, slightly yellowish dentinal color, which is the normal baseline for unwhitened teeth. Her current shade is a bright, natural white that sits comfortably within the range of realistic tooth color without tipping into the uncanny bright white that signals artificial restorations.
Professional whitening of this quality requires careful technique and typically a maintenance protocol: periodic touch-up treatments, custom whitening trays for home use, and avoidance of significant staining agents in the diet. Given the frequency of her public appearances and the consistency of her tooth shade across years, it is likely that she follows a regular maintenance whitening protocol. This is actually one of the most cost-effective long-term strategies for maintaining a bright smile and is accessible to patients at virtually any dental practice.
What Happened to Billie Eilish’s Teeth? A Final Expert Review
Summarizing everything known and reasonably inferred about Billie Eilish’s teeth from a dental professional’s perspective, the story is genuinely positive. A naturally talented young woman who entered the public eye with typical teenage dental imperfections chose a sensible, staged, and conservative approach to cosmetic improvement. She underwent clear aligner orthodontic treatment, closing a gap and correcting mild crowding. She likely followed this with professional whitening and conservative composite bonding to refine tooth shape. She did not undergo the dramatic full-arch veneer overhaul that many celebrities choose and that often leaves teeth looking artificially perfect rather than naturally beautiful.
The result is a smile that enhances her natural features, suits her face, and holds up under scrutiny from professional clinicians. It is, from a clinical standpoint, an excellent case. From a patient perspective, it is an instructive example of what thoughtful, phased dental improvement can achieve. And from a cultural perspective, the fact that this transformation happened gradually, visibly, and without any attempt at concealment, made it relatable and encouraging to millions of young people who saw their own dental concerns reflected in a global superstar.
If the Billie Eilish teeth journey has one central takeaway for anyone considering their own dental care, it is this: the best cosmetic dentistry is the kind that makes you look more like yourself, only better. Not a different person, not an idealized mannequin, but you, with the best version of the smile you were naturally developing toward all along. That is what she achieved, and it is what skilled dental professionals aim for with every patient who sits in the chair.
Frequently Asked Questions About Billie Eilish Teeth
Did Billie Eilish get her teeth done?
Yes, almost certainly. The evidence from years of public appearances strongly supports that she underwent clear aligner orthodontic treatment, professional whitening, and likely some conservative cosmetic refinement such as composite bonding. She has not publicly confirmed specific procedures, but the visual evidence is consistent and coherent.
Does Billie Eilish have veneers?
The available evidence does not strongly support traditional porcelain veneers. Her teeth retain natural optical characteristics including translucency and slight color variation that are typically absent in heavily veneered smiles. Conservative bonding or no veneers at all is the more likely explanation based on observable evidence.
Did Billie Eilish wear braces?
Traditional bracket-and-wire braces have never been visibly observed. Her orthodontic treatment appears to have been exclusively clear aligner-based, consistent with Invisalign or a similar system.
What is the gap in Billie Eilish’s teeth?
A diastema between her upper central incisors was visible in early career photographs from 2017 and 2018. This gap was progressively closed during her clear aligner treatment and is no longer present in recent photographs.
Are Billie Eilish’s teeth natural?
Her underlying natural teeth appear to form the foundation of her current smile, with professional refinements applied on top. Unlike heavily veneered smiles, hers retains the optical characteristics of natural tooth structure, suggesting her actual teeth were preserved and enhanced rather than covered or replaced.
Does Billie Eilish have gold teeth?
No permanent gold dental modifications have been observed. Grillz, which are removable decorative accessories worn over the teeth, have appeared in some styled editorial and artistic contexts. These are fashion items and not permanent dental work.
How long did Billie Eilish’s dental transformation take?
Based on the photographic timeline, her visible orthodontic phase ran from approximately 2019 to 2021, approximately 18 months of active aligner treatment. Further cosmetic refinement appears to have occurred through 2022, making the full transformation approximately three to four years from beginning to polished completion.
