Heading into 2022, Billie Eilish's dental transformation appeared complete. Her smile was now so flawless that it sparked a new wave of fan and media speculation – this time over whether she had gotten porcelain veneers to achieve such perfection. Her teeth in 2022 were 'perfectly white, perfectly aligned and [had] a shine almost unimaginable', as one celebrity dental blog described. Such superlatives led many to assume that some form of cosmetic dentistry (beyond just Invisalign and whitening) must be at play. Despite the rumors, no concrete evidence of veneers ever emerged. Billie never commented on it, and no cosmetic dentist has claimed credit for a veneer procedure.
In her early teens, Billie Eilish had what she later described as a 'classic teenage smile' – not Hollywood-perfect, but authentic. Photographs from before fame show that one of her lateral incisors was somewhat rotated, and she had a slight gap (diastema) between her front teeth. These minor imperfections gave her smile a quirky charm, but they also became a source of self-consciousness for the young singer. In a 2017 Billboard interview, Billie admitted she didn't like smiling because of what she jokingly called 'an ugly little tooth' that 'likes to poke out,' revealing a deep-seated insecurity about her smile. In fact, her debut EP was pointedly titled 'dont smile at me,' hinting at her reluctance to smile openly in photos.
By her mid-teens, Billie Eilish embarked on a clear-aligner orthodontic journey that would significantly transform her smile. Both Billie and her brother Finneas O'Connell wore Invisalign aligners for about a year and a half to straighten their teeth. Billie chose Invisalign specifically because she wanted to fix the 'slight gap' in her front teeth without having to get noticeable metal braces. She made no secret of this orthodontic treatment – in fact, in her 2019 'Bad Guy' music video, Billie famously begins the video by removing her clear aligners from her mouth on camera, a cheeky acknowledgment of her dental gear.
With her teeth now straight, Billie turned to enhancing their color and shape. In 2020, fans and media began to observe that her smile looked brighter than before – not just straight, but truly gleaming white. Billie has openly documented her experiences with teeth whitening, even sharing videos of the whitening process on social media. These whitening treatments gave her a more radiant smile to match her growing superstar status. By the time of award shows and high-profile appearances in 2020–2021, Billie's teeth appeared uniformly bright white, suggesting she invested in professional whitening (or high-end at-home kits) once her Invisalign treatment concluded.
In the last couple of years, Billie Eilish has fully owned her smile – even experimenting with decorative dental accessories – all while continuing to maintain her oral health. In August 2023, Billie surprised fans by posting Instagram photos of herself with diamond-studded grillz on her teeth. In the pics, she sported a gold cap on one of her molars and a tiny diamond gem in the gap between her two front teeth, adding some sparkle to her grin. This temporary 'bling' was purely cosmetic (grillz are removable covers and do not alter the teeth underneath), but it certainly got people talking. As of 2025, Billie Eilish's smile is a striking part of her image – healthy, aligned, and camera-ready.
Dr. Emily Parker
DDS, Orthodontist
Dr. Emily Parker, DDS, who analyzed Billie's smile in detail, concluded that 'while speculation persists about Billie Eilish having veneers… the evidence suggests that Billie's smile transformation is primarily attributed to Invisalign and her teeth whitening practices.' In her analysis, the shape and subtle translucency of Billie's teeth still looked consistent with natural teeth – just better aligned and whitened.
Dr. Sara Hart
Cosmetic Dentist
Dr. Sara Hart (via a TikTok 'veneer check' series) analyzed Billie's teeth and noted that her two front teeth did stand out in color, initially leading her to suspect veneers – but on closer look she leaned toward it being a result of whitening and natural variation, because 'they just look like her natural teeth' and not like obvious caps.
Dr. Jordan Davis
Cosmetic Dentist
Dr. Jordan Davis, another cosmetic dentist, posted his take on Billie's smile in 2024, saying after a few years her teeth still look as natural as the day any work was finished, and 'luckily, she doesn't have that fake 'Halloween teeth' look', implying no overly fake veneers were used.

Some curious details fueled rumors of further cosmetic dental work. Observers noticed that Billie's two front teeth (central incisors) often appeared whiter than the rest – a slightly uneven coloration. Another possibility floated by dentists is the use of ultra-thin 'no-prep' veneers or bonding on a couple of teeth to perfect the smile's appearance. These 'label veneers' (as one blog termed them) could subtly refine a tooth's shape or color without the telltale bulk of traditional veneers.
In the last couple of years, Billie Eilish has fully owned her smile – even experimenting with decorative dental accessories – all while continuing to maintain her oral health. Notably, during the 2024 Oscars telecast, a few observers thought Billie had a slight lisp, which is a common side-effect of speaking while wearing clear aligner trays. Since Billie doesn't usually have any speech impediment, that tiny lisp led to speculation that she might have had her Invisalign retainer in that night.
