Ever noticed how some people just have that distinct look? Those two front teeth that stand out a bit more than the rest. We usually call them "rabbit teeth," but in the dental world, they're technically known as prominent maxillary central incisors. It’s a look. Some people love it, some people spend thousands of dollars to change it, and honestly, the science behind why it happens is way more interesting than just "genetics."
You've probably seen it on famous faces. Think Freddie Mercury or even Kirsten Dunst. It gives a certain character to a smile that perfectly straight, bleached veneers just can't replicate. But for a lot of people, having people with rabbit teeth as a descriptor for their own face isn't always a compliment. It’s a mix of biology, habit, and sometimes, a little bit of bad luck during childhood development.

What's Actually Going On in Your Mouth?
Basically, "rabbit teeth" usually refers to a type of malocclusion. That's just the fancy medical word for "teeth that don't line up right." Specifically, we’re talking about an overbite or an overjet. People often use those terms interchangeably, but they aren't the same thing at all.
An overbite is when the upper teeth overlap the bottom teeth vertically. An overjet, which is what most people mean when they talk about rabbit teeth, is when the upper teeth protrude outward at an angle toward the lip. It’s that horizontal gap. According to the American Association of Orthodontists, about 20% of the population has some form of significant overjet. That’s a lot of people.
Why does it happen?
Genetics is the big one. If your dad has prominent front teeth, there’s a solid chance you will too. Your jaw size is inherited. If you inherit a small lower jaw from your mom and large teeth from your dad, those teeth have nowhere to go but out. It's like trying to fit ten people into a five-person elevator. Something is going to get pushed against the door.
The Habits That Shape Your Smile
But it isn’t just your DNA. Habits during those crucial years when your adult teeth are coming in play a massive role. Thumb sucking is the classic culprit. When a kid sucks their thumb, the constant pressure of the thumb against the back of the front teeth and the roof of the mouth literally tilts the teeth forward. It also narrows the dental arch. Pacifiers used past the age of three do the exact same thing.
Then there’s tongue thrusting. This is a weird one. Some people, when they swallow or speak, press their tongue forward against their front teeth instead of against the roof of the mouth. Do that thousands of times a day, every day, for years? Your teeth are going to move. It’s a slow-motion push that eventually results in that buck-toothed appearance.
Is it Actually a Health Problem?
Look, if you like the way it looks, that's great. Many people find it charming. But from a purely clinical perspective, people with rabbit teeth often face specific challenges that have nothing to do with aesthetics.
First, there’s the risk of trauma. It sounds scary, but it’s simple physics. If your front teeth stick out further than your lips, they are the first thing to hit the ground if you trip or get hit in the face during a basketball game. Studies published in journals like Dental Traumatology show that children with an overjet greater than 3mm are significantly more likely to suffer dental injuries.

Then you have the speech stuff. Your teeth, tongue, and lips have to work in perfect harmony to make certain sounds—especially "s," "f," and "sh." If the teeth are too far forward, the tongue can’t find the right "landing zone," leading to a lisp or a whistling sound. It’s not just in your head; it’s a physical obstruction.
The Dry Mouth Dilemma
Another thing people don't talk about is lip incompetence. That’s the medical term for when your lips can’t naturally close over your teeth without effort. If your teeth are always exposed to the air, they get dry. Saliva is your mouth's natural defense against tooth decay. It neutralizes acids and washes away food bits. Without it, those front teeth are sitting ducks for cavities and gum disease.
It’s also exhausting for the jaw muscles. Your mouth wants to be closed. If your teeth are forcing it open, your jaw muscles are constantly working to compensate, which can lead to TMJ disorders or chronic headaches. It’s all connected.
The Cultural Shift: Embracing the "Flaw"
Interestingly, we’re seeing a bit of a pushback against the "perfect" Hollywood smile. In some cultures, prominent front teeth are seen as a sign of youth or even good luck. In Japan, there was a trend called "yaeba," where people actually paid dentists to make their teeth look more crooked or prominent because it was seen as "kawaii" or cute.
In the West, models like Lara Stone or Georgia May Jagger have made careers out of their unique dental structures. It’s a rejection of that "uncanny valley" look of perfectly symmetrical veneers. There’s a certain authenticity to it.
However, there is a limit. While a slight protrusion can be a "signature look," a severe overjet can cause genuine psychological distress. For a teenager, being called "Bugs Bunny" or "Bucktooth" isn't a minor thing. The psychological impact of dental appearance is well-documented in the American Journal of Orthodontics and Dentofacial Orthopedics. Kids with visible dental issues are often targets for bullying, which can affect self-esteem well into adulthood.
Fixing Rabbit Teeth: Not Just Braces Anymore
If someone decides they want to change their look, the options are way more advanced than the "metal mouth" days of the 90s.
- Invisalign and Clear Aligners: These are great for mild to moderate cases. They use plastic trays to gradually push the teeth back. But, and this is a big "but," they don't always work for severe jaw-based overjets.
- Traditional Braces: Still the gold standard for a reason. They give the orthodontist total control over the movement of each tooth. They can also use rubber bands to pull the upper arch back and the lower arch forward.
- Palatal Expanders: Often used in kids. It widens the upper jaw so there’s actually room for the teeth to sit where they belong.
- Veneers: This is the "quick fix." A dentist shaves down the natural tooth and sticks a porcelain shell over it to make it look straight. It’s fast, but it’s permanent and doesn't fix the underlying bite issue.
- Jaw Surgery: For the most extreme cases where the actual bone structure is the problem. It’s a major procedure, but it can be life-changing for someone who can’t eat or breathe properly because of their jaw alignment.
Managing Your Dental Health Right Now
If you or your child have prominent front teeth, you don't necessarily need to rush to a surgeon. But you do need to be more careful than the average person.
Start with a custom mouthguard. If you play any kind of contact sport—even just recreationally—you need one. Because those teeth are "out there," they are vulnerable. A $50 mouthguard can save you a $5,000 dental implant later.
Pay attention to your breathing, too. Many people with rabbit teeth are "mouth breathers." This is often because it’s physically difficult to keep the mouth closed. Mouth breathing leads to a host of issues, including poor sleep quality and narrowed facial development in children. If you find you're always breathing through your mouth, it might be worth seeing an ENT (Ear, Nose, and Throat doctor) or a myofunctional therapist.
Myofunctional therapy is basically physical therapy for your mouth. They teach you how to rest your tongue in the right spot and how to swallow correctly. It sounds simple, but it can actually prevent teeth from drifting further forward over time. It’s about training the muscles to stop pushing the teeth out.
Actionable Steps for Moving Forward
If you're looking at your smile in the mirror and wondering what to do, don't just jump into the first treatment you see on Instagram.

- Get a professional evaluation: See an orthodontist, not just a general dentist. Orthodontists have two to three years of extra training specifically in tooth movement and jaw alignment.
- Check for underlying issues: Ask about your airway. Sometimes prominent teeth are a symptom of a narrow airway or sleep apnea.
- Evaluate the "Why": Are you fixing it because you don't like the look, or because your jaw hurts and you're chipping your teeth? The "why" determines the treatment.
- Invest in protection: If you have an overjet, buy a high-quality mouthguard today. Do not wait until after an accident happens.
Ultimately, having rabbit teeth is a physical trait like any other. It can be a health hurdle, or it can be a unique feature that defines your face. The key is making sure that your bite is functional and your teeth are protected, regardless of how much they stand out. Understand the mechanics of your own mouth so you can make an informed choice about whether to embrace the look or seek a correction.
