The smile transformations of the Stranger Things cast have recently emerged as a notable topic of discussion across social media. Thanks to orthodontic advancements and cosmetic touch-ups, both fans and dental professionals have observed how much the smiles of the young and adult actors have changed over time. In this article, we take a closer look at each cast member's dental journey—drawing from their comments and insights from our expert team. So if you're ready, let's dive in and start with Millie Bobby Brown.
Millie Bobby Brown - Eleven
In a 2024 interview, Millie Bobby Brown mentioned that young Eleven needed orthodontic treatment, and this actually reflected her own dental situation as a teenager. Photos from that time show that Millie had noticeable crookedness and alignment issues. Her recent pictures, however, make it clear that she went through orthodontic treatment and later chose veneers for a more polished look.
To close the gap near her canine teeth, dentists used a method that avoided removing too much enamel, and her front veneers were designed with a soft, slightly square shape. The final result looks very refined, but some fans still think her naturally crooked smile gave her a charming and unique look.
Finn Wolfhard - Mike Wheeler
When you look at Finn Wolfhard's smile over the years, there's no indication that he had veneers. But comparing his 2015 Stranger Things photos with his more recent ones shows that his teeth have become noticeably straighter—especially his canines. This kind of improvement can happen naturally as someone grows, but it might also be the result of orthodontic treatment. Today, Finn's smile looks more even, balanced, and mature than it did in his early teens.
Noah Schnapp - Will Byers
Looking at Noah Schnapp's photos from 2015, you can see that his teeth were completely natural—small, slightly spaced, and typical for his age. His smile's alignment had significantly improved by 2018, indicating that he might have received orthodontic treatment at that time. After 2020, his teeth started to look brighter, more symmetrical, and overall more polished, hinting at possible cosmetic treatments like whitening, light shaping, or even veneers.
Between 2023 and 2025, the change became even more obvious. His teeth looked more even in size, much whiter. Another clear improvement is the correction of the inward tilt seen in his back teeth in 2015—this has completely disappeared in his recent photos.
Gaten Matarazzo - Dustin Henderson
Gaten Matarazzo has a genetic condition called Cleidocranial Dysplasia (CCD), which affects the way his jaw and teeth develop. Because of this, he grows many extra teeth that stay trapped under the gums, causing both functional and aesthetic issues. His treatment over the years has focused on removing these extra teeth and helping his adult teeth come in correctly. In 2020, he had another surgery as part of this ongoing process.
Caleb McLaughlin - Lucas Sinclair
Back in 2015, Caleb McLaughlin's smile looked natural, a little uneven, and slightly discoloured—pretty normal for his age. By 2017, his teeth appeared brighter and more evenly aligned. When you look at his photos from 2020, his smile seems much more polished: whiter, straighter, and overall more refined. This suggests he may have had some cosmetic treatments like professional whitening, light shaping, or even a few veneers.
Between 2023 and 2025, Caleb's teeth appear longer and more proportionate, his smile has become more Hollywood-like, and the tiny spaces between his teeth seem to have disappeared.
Sadie Sink - Max Mayfield
Sadie Sink's smile has undergone significant aesthetic improvement over the years, becoming whiter, more symmetrical, and more balanced. Photographs from 2013-2015 show her teeth retaining their natural structure, with slight irregularities and a matte hue. Minor cosmetic touch-ups and initial whitening treatments during this period have resulted in initial improvements in her smile aesthetics.
After 2018, thanks to regular professional teeth whitening procedures, Sadie's teeth have become noticeably lighter in color, and their surface texture has become smoother and more uniform. Examining the images reveals that, aside from the whitening procedures, no significant cosmetic or restorative dental interventions were performed. This natural yet effective transformation of Sadie Sink's smile demonstrates the remarkable results even minimal cosmetic procedures can produce when planned correctly.
Winona Ryder - Joyce Byers
When examining recent photographs of Winona Ryder, who had a remarkably aesthetic smile even in her youth, it appears that one of her upper front teeth, in particular, has now become more symmetrical with the opposing tooth. Visual analysis suggests that veneers may have been applied to a total of six front teeth between the canines to achieve this symmetry and create a more balanced smile. Although Winona Ryder has not officially stated this, the changes in tooth form, surface texture, and color harmony provide strong evidence supporting the possibility of veneers.
David Harbour-Jim Hopper
An examination of David Harbour's dentition reveals no significant cosmetic interventions or structural changes over the years. Photographs show that his dental form and alignment largely maintain their youthful natural appearance, with no evidence of any restorative or cosmetic procedures. This suggests that Harbour maintained consistent oral and dental health and that the likelihood of him having undergone any cosmetic dental procedures is extremely low.
Natalia Dyer - Nancy Wheeler
Natalia Dyer's teeth have undergone a significant aesthetic transformation, starting from the natural and innocent smile of her childhood and continuing until 2025. The minor imperfections and natural youthful appearance of the 2010s became more aligned and brighter after 2015 with regular whitening and light cosmetic touch-ups. In 2020 and beyond, she has achieved a flawless, symmetrical, and radiant appearance, perhaps thanks to porcelain veneers and professional cosmetic procedures, that we might call the "Hollywood smile."
Charlie Heaton - Jonathan Byers
When you look at Charlie Heaton's teeth, there's really no sign that he's had any dental work done. His teeth still have their natural shape, alignment, and texture, and there's nothing that suggests he's had bonding, veneers, whitening, or any other cosmetic procedure. Everything about his smile points to it being completely natural. Based on all the photos and observations, it's clear that Charlie Heaton hasn't had any dental treatment.
Maya Hawke - Robin Buckley
Maya Hawke's smile has been practically reimagined over the years. In the early stages of her career, her teeth were completely natural, with slight discolorations and minor irregularities—a perfectly normal occurrence for most people. But as her acting career took off and her on-screen appearance became more prominent, her smile was significantly brightened and shaped by orthodontic treatments from 2015 to 2020.
Conclusion
Most members of the Stranger Things cast have experienced some level of dental transformation as their careers have progressed. From orthodontic improvements to whitening and cosmetic touch-ups, many of them chose treatments that helped refine their on-screen appearance. These changes highlight how common and accessible dental enhancements have become, especially for actors whose smiles play a key role in their public image.
