If there’s one thing the internet loves more than a Single’s Inferno romantic snooze, it’s a forensic-level glow investigation. And right now? All eyes are on Su-ben’s smile.
A few new clips were released after the show and suddenly the timeline turned into a dental exam.
People are zooming in, screenshots, side-by-sides… and the running theory is that it might have had veneers. Has he confirmed anything? No. But did that stop anyone? Also not…
People think that Su-been has made a change
The veneer is so ugly! She had such a beautiful smile 😭😭😭😭

Speculation really took off after new interview clips and social media posts began to circulate.
In them, Su-been’s teeth look noticeably brighter and more even than in the show.
A viral post on X clearly said, “Veneer is so ugly! She had such a beautiful smile,” which is both dramatic and very on-brand for reality fans.
Here’s the important part, though. Su-ben has not said publicly that he has faked it. There is no statement, no interview confirmation, nothing official. Right now, it’s pure speculation.
Also, teeth can look very different depending on lighting, camera angles, whitening treatments, and even video filters. HD filming and bright studio lights can make natural teeth look super white and super even.
And veneers themselves are simply thin shells glued to the front of teeth to improve shape or color, they’re cosmetic, but they’re also incredibly common in the entertainment industry.
So yes, people think something has changed. But until Su-been says otherwise, this remains in the “internet theory” category.
Some cast members of Single Inferno chose to undergo surgery
Part of why the veneer theory has gained so much traction is because cosmetic surgery isn’t exactly unheard of in the Single’s Inferno universe.
Some cast members have openly admitted to plastic surgery, and several alumni have been candid about their modifications.
Lee Si-an, for example, has talked about a nose job and a minor facial contouring procedure. They were refreshingly upfront about it, which the fans really appreciated. Meanwhile, Song Ji-a also previously revealed that she had a nose job at the age of 17, tackling the rumors head-on instead of letting the speculations fester.
The key word here is acceptable. In these cases, the cast members themselves confirmed their procedures. This is very different from people guessing based on a few comparison photos.
And to be fair, cosmetic enhancements, from surgeries to injectables to dental work, are incredibly common in the realms of reality TV, especially in South Korea’s ultra-competitive beauty culture. But there is a big difference between something being possible and something being asserted.
Right now, Su-been sits firmly in the speculation zone. People think his smile looks different. Some prefer “before.” Some think he looks great either way. And others are just too preoccupied with whether he and Hee-Sun are still together to care about his fangs.
