A great smile can make a huge difference, and many celebrities know this better than anyone. Over the years, plenty of famous stars have quietly upgraded their teeth with veneers or dentures, turning uneven or discolored smiles into dazzling ones.
Some changes are subtle, while others are jaw-dropping transformations. Read on to find out which 17 celebrities switched up their smiles and why.
1. Miley Cyrus
Before fame hit full force, Miley Cyrus had misaligned teeth that needed braces to correct. Once she was in the spotlight, she went a step further and got porcelain veneers on her upper teeth.
The result? A radiant, symmetrical smile that photographs beautifully every time.
Veneers also help prevent staining, which is a huge bonus for someone always in front of cameras. Her transformation is one of the most talked-about in Hollywood.
2. Kendall Jenner
Kendall Jenner’s early photos tell a different story from what fans see today. Her front teeth were slightly narrow and uneven, with lateral incisors that appeared darker and sat further back than the rest.
After getting dental veneers, her smile became noticeably straighter and more balanced. Fans and beauty editors alike have pointed out the glow-up.
For a supermodel constantly in the public eye, having a flawless smile is practically part of the job description.
3. Kylie Jenner
Growing up in front of cameras meant Kylie Jenner’s dental journey was well-documented by fans online. As a kid, she had small gaps, jagged edges, and crooked front teeth where the incisors were noticeably longer than the rest.
Veneers completely changed the picture. Now her smile looks polished, natural, and sophisticated.
It is the kind of transformation that inspired a wave of young fans to ask their dentists about cosmetic dental options for themselves.
4. Dua Lipa
Dua Lipa wore braces as a child, so dental care was always part of her story. After having her wisdom teeth removed, she got crowns on her back teeth for better alignment, followed by veneers on her front teeth.
The end result is a brilliant smile with elegant, proportioned teeth that curve naturally outward. Many dentists actually point to her smile as a great example of veneers that look completely real rather than overly artificial or blindingly white.
5. Tom Cruise
Early career photos of Tom Cruise reveal a very different smile from the one the world knows today. His teeth were misaligned and uneven, which stood out even in his early film roles.
A combination of orthodontic treatment and dental veneers turned things around completely. Now his teeth are straight, white, and perfectly aligned.
That confident, wide smile has become one of his most recognizable features, helping fuel his charismatic leading-man image for decades on screen.
6. Zac Efron
Back in his High School Musical days, Zac Efron had a noticeable gap between his front teeth and some discoloration. It was charming in its own way, but Hollywood had other plans.
Through a combination of dental bonding, teeth whitening, and porcelain veneers, that gap was closed and his smile became a symmetrical standout. The result is a radiant, polished look that matches his leading-man status.
His transformation is a popular reference point in cosmetic dentistry discussions worldwide.
7. Demi Lovato
Demi Lovato’s early photos show teeth that were uneven and visibly damaged, something that was noticeable even in professional photoshoots. Veneers and cavity fillings early in her career helped improve the overall look significantly.
She later added clear aligners to correct misalignment and close a noticeable tooth gap. The combination approach gave her a striking, properly aligned smile that still looks natural and not overdone.
Her dental journey shows that sometimes the best results come from mixing multiple treatments.
8. Demi Moore
Losing a tooth is stressful for anyone, but when you are one of Hollywood’s biggest stars, the pressure to fix it fast is even greater. Demi Moore reportedly had veneer treatment after experiencing tooth loss, and the results were impressive.
Her teeth now look whiter, more uniform, and beautifully shaped. The work contributes to a youthful appearance that keeps fans doing double-takes.
It is a solid reminder that cosmetic dentistry is not just about vanity but also about restoring confidence after dental setbacks.
9. Victoria Beckham
Victoria Beckham was rarely caught smiling wide in her early Spice Girls days, and her slightly crooked teeth may have had something to do with that. Porcelain veneers changed everything, giving her a completely straight and uniform set of teeth.
The transformation enhanced the overall appearance of her face, adding a fuller, more youthful quality. Today she smiles with noticeably more confidence.
Cosmetic dentists often use her smile as a textbook example of how veneers can subtly but powerfully change a person’s look.
10. Millie Bobby Brown
Stranger Things fans who have followed Millie Bobby Brown since the early seasons have noticed a clear change in her smile over the years. Her teeth were somewhat crooked early on, which was completely normal for a young teenager in the spotlight.
Porcelain veneers gave her a stunningly even, bright, and flawless smile that fits her growing celebrity status. The change feels natural rather than dramatic, which is exactly what good cosmetic dentistry should accomplish for someone her age.
11. Scarlett Johansson
Scarlett Johansson’s smile has always been part of her appeal, but a closer look at early versus recent photos reveals some noticeable dental work. Composite bonding and veneers have brightened her teeth and created a more balanced, even look.
What makes her smile stand out is that it does not look overdone. The work complements her natural attractiveness without screaming “cosmetic procedure.” For anyone considering veneers, her smile is a great example of how to achieve results that look genuinely authentic and camera-ready.
12. Ben Simmons
Not many NBA stars make the news for their dental work, but Ben Simmons is an exception. He had noticeable gaps between his teeth and they were not particularly straight, which caught the attention of fans and media alike.
After orthodontic treatment and porcelain veneer shells, he now sports a bright, even smile that fans have nicknamed his “Hollywood smile.” The transformation proves that cosmetic dentistry is not exclusive to actors and musicians. Athletes care about their appearance just as much as anyone else in the public eye.
13. Hilary Duff
Hilary Duff had one of those smile stories that started with an accident. After chipping a tooth, she decided to go all-in on a full smile makeover using porcelain veneers.
The treatment corrected her previously crooked teeth and created a more harmonious, radiant result that looks completely natural. Her makeover story actually encouraged a lot of fans to consider cosmetic dentistry after their own dental mishaps.
Sometimes a small accident ends up being the push someone needs to finally address a long-standing dental concern.
14. George Clooney
George Clooney’s natural teeth were reportedly yellow, worn, stained, and cracked, partly because of a long-standing teeth-grinding habit. Not exactly the look you would expect from one of Hollywood’s most celebrated leading men.
Veneers gave him a sparkling white, clean-cut appearance while keeping a natural tooth structure intact. Dentists who have commented on his smile say the work is very well done and convincingly real.
His transformation is a perfect case study in how veneers can handle multiple dental issues at once.
15. Lindsay Lohan
Lindsay Lohan was photographed extensively throughout her early career, and older images clearly show teeth that were discolored and uneven compared to her current look. The contrast between then and now is pretty striking.
Porcelain veneers gave her a bright, aligned smile that looks polished and put-together. The transformation is part of a broader personal reinvention that fans have cheered on over the years.
Her updated smile is a small but meaningful piece of the comeback story she has been writing for herself.
16. Morgan Freeman
Morgan Freeman has one of the most recognizable voices in Hollywood, but his smile has also drawn attention over the years. He has openly discussed using dentures as a solution to dental health challenges he faced over time.
Dentures often carry an outdated stigma, but Freeman’s willingness to talk about them helps normalize a very common dental solution. Modern dentures look remarkably natural and fit comfortably, making them a practical choice for many people.
His openness is a refreshing change from the usual Hollywood silence on dental work.
17. Clark Gable
Clark Gable was known as the “King of Hollywood,” but behind that famous charm was a dental secret most fans never knew about. By the time he was just 32 years old, severe gum disease had caused him to lose most of his natural teeth.
Dentures allowed him to maintain his confident, charismatic on-screen persona throughout his career. His story is one of the earliest celebrity examples of how dental solutions can preserve a public image.
It also shows that dental health challenges are nothing new, even for the biggest stars of any era.
