What Is the American Girl Doll Teeth Trend?

The term “American Girl Doll Teeth” refers to a dental aesthetic that mimics the small, slightly spaced front teeth seen on the classic American Girl dolls from the 90s and early 2000s. These dolls, known for their porcelain-smooth skin, glassy eyes, and that distinctive closed-mouth grin, have become a nostalgic touchstone for many Gen Z and millennial users on TikTok. But in a twist that’s both ironic and disturbing, some people are altering their real smiles to match this doll-like appearance.

The trend isn’t just about looking like a toy. It’s tied to a broader fascination with “baby aesthetics” and youthful features, which have been growing in popularity across fashion, beauty, and even plastic surgery trends. The idea is that smaller front teeth give off a more “innocent” or “cute” vibe, which aligns with certain online aesthetics like “cottagecore” and “soft girl.” But unlike makeup or filters, this is a permanent physical change—one that can come with serious consequences.

So, where did this idea come from? It turns out, the trend has been around for a while. It first gained attention in early 2021 and has resurfaced multiple times since, especially on TikTok, where short-form videos can quickly amplify niche ideas into mainstream movements.

Why Did the Doll Teeth Trend Go Viral?

Like most viral trends, the American Girl Doll Teeth movement started with a few key influencers and a bit of nostalgia. TikTok user Christina Scully (@uhmmokayyy22) went viral after sharing a clip about how she filed down her own teeth when she was just 14. Her reasoning? She thought her front teeth looked too prominent and reminded her of those classic American Girl smiles. That post, and others like it, helped spark a wave of similar content.

But why now? Part of it is the broader resurgence of Y2K and early 2000s aesthetics. From low-rise jeans to butterfly clips, the early 2000s are back in a big way. And for many Gen Z users who grew up playing with American Girl dolls, the iconic teeth became a symbol of childhood innocence. Mimicking that look is a way to tap into that nostalgia—but also, in a way, to reclaim or redefine it.

Another factor is the influence of filters and digital aesthetics. With the rise of AI filters that smooth skin, enlarge eyes, and refine jawlines, people are getting used to seeing digitally altered versions of themselves. When real-life features don’t match those idealized images, some turn to physical alterations to bridge the gap. The American Girl Doll Teeth trend is just one of many ways people are trying to match their real smiles to their filtered ones.

Real-Life Impacts of the Trend

For some, the American Girl Doll Teeth look is just a joke—a funny filter or a meme. But for others, it’s become a real-life beauty standard. Videos showing people filing down their teeth or joking about how they “look like a doll” have been viewed millions of times. And while many are quick to dismiss these clips as harmless fun, there’s a growing concern about how this might be influencing teens and young adults.

Take, for example, the case of Christina Scully. She admitted to filing her teeth down at a very young age, without professional supervision. While she may not have suffered serious consequences, not everyone is so lucky. Improper dental filing can lead to tooth sensitivity, increased risk of decay, and even permanent damage. And yet, some people are still choosing to do it at home.

Meanwhile, dentists and orthodontists are raising alarms. They’re seeing more young patients asking about ways to reduce the size of their front teeth or create that “doll gap.” While there are safe, professional ways to reshape teeth—like enameloplasty or veneers—those procedures come with their own costs and risks. And the viral nature of the trend means many are trying to do it themselves, without any guidance.

Dental Risks of Filing Down Teeth

Here’s the thing: teeth are not like hair or nails. Once you file them down, there’s no growing them back. And unlike cosmetic changes like hair dye or makeup, dental modifications are permanent and can have long-term consequences. Here’s what you need to know about the risks:

• Tooth Sensitivity: Filing down enamel can expose the dentin layer underneath, making teeth more sensitive to hot and cold.
• Increased Risk of Decay: Thinning the enamel can make teeth more vulnerable to cavities and bacterial damage.
• Structural Damage: Improper filing can weaken the tooth structure, leading to cracks or fractures.
• Costly Repairs: If damage occurs, fixing it can require expensive dental procedures like bonding, crowns, or even root canals.

And if someone tries to file their teeth at home using nail files or sandpaper—something that has been documented in some TikTok videos—the risks go up even more. These tools are not designed for dental use and can cause uneven wear, microfractures, and infections.

“I’ve had patients come in with serious sensitivity after trying to file their own teeth,” one dentist shared online. “It’s not something you can undo. Once the enamel is gone, it’s gone for good.”

So, while the American Girl Doll Teeth look might seem cute or trendy, the reality is far from glamorous. It’s important for viewers—especially younger ones—to understand that this isn’t a safe or reversible change.

How to Talk to Teens About Dental Fads

If you’re a parent, teacher, or mentor, you might be wondering how to approach this topic with younger people. After all, teens are often drawn to trends that seem rebellious, unique, or attention-grabbing. So how do you address something like this without sounding judgmental or dismissive?

Here are a few tips:

1. Start with Empathy: Acknowledge that they’re not the only one who might feel self-conscious about their smile. Let them know it’s okay to feel unsure or insecure about how they look.
2. Provide Accurate Information: Share what dentists are saying about the risks. If possible, show them videos or articles from professionals who explain why dental filing is dangerous.
3. Encourage Open Dialogue: Ask them what they think about the trend. Do they find it funny? Do they feel pressure to look a certain way? Listen more than you speak.
4. Offer Alternatives: If they’re unhappy with their smile, talk about safer options like orthodontics, whitening, or even just embracing their natural look. Confidence starts with self-acceptance.

It’s also a good idea to monitor what’s trending on platforms like TikTok. While it’s not realistic to police everything your teen sees, being aware of what’s popular can help you guide them in a way that feels supportive rather than intrusive.
