Whether or not a "gummy smile" is considered cute varies from person to person. While the amount of gum visible when you smile affects the overall impression, it isn't the only factor that determines your attractiveness. If it doesn't bother you, treatment isn't necessarily required.
"People tell me my gummy smile is cute, but it bothers me." "I wonder what people think when my gums show when I smile."<p> </p>
Have you ever felt that way?
While some people consider a smile that shows their gums to be their best feature, others may be conscious of their mouth when having their picture taken.
There's no need to force yourself to change either of those feelings.
In this post, BIANCA CLINIC will discuss the impact of a smile. Let’s explore this topic together—not only from a dental perspective but also by considering what makes a smile seem cute.
Is a gummy smile cute? The impression a smile makes varies from person to person.
A "gummy smile" refers to a condition in which the upper gums are relatively visible when a person smiles. It is a cosmetic characteristic and does not in itself indicate a medical condition.
While some people find a "gummy smile" cute, others prefer a smile that doesn't show much gum.
To begin with, what people find appealing varies from person to person.
What I think is important is not just how others see you, but how you yourself feel about your smile.

What Makes a "Gummy Smile" Cute? Considering the Balance of a Smile from a Dental Perspective
The appeal of a gummy smile isn't just about how much gum is visible; the impression it makes also depends on the balance between the teeth and lips, as well as the natural expression when you smile.
Let's take a look at the factors that contribute to the appeal of a smile from a dental perspective.
The Amount of Gum Visible and Aesthetic Evaluation
In fact, research has shown that the impression people form of you changes depending on how much of your gums are visible when you smile.
A 2022 report summarizing 34 studies on the general public's evaluation of smiles found that smiles in which the gums are barely visible tended to be preferred.
On the other hand, even if about 3 mm of the gums are visible, this is considered to be within an acceptable range [1].
In other words, just because a little bit of your gums show doesn’t mean your smile will look bad. After all, everyone has their own standards for what they find cute.
The balance between your teeth, lips, and gums also affects your overall appearance.
Even if the same amount of gum is visible, the impression a smile makes can vary depending on how the front teeth look, the shape of the upper lip, and the movement of the mouth.
There’s one more thing I’d like you to know. It’s that the smile you make when taking a photo is different from the expression you make when you laugh spontaneously.
A study comparing photos and videos of 380 people found that people tended to show more of their gums when they smiled naturally [2].
A single photo isn't enough to fully capture the charm of that person's smile.
Why do people find a gummy smile cute?
When we think, “She has a gummy smile, but she’s cute,” we’re probably not just focusing on her gums.
For example, the way the corners of their eyes and mouth turn up when they smile. I suppose people perceive this—including the way they smile naturally—as part of their unique charm.
On social media and elsewhere, Erika Toda is sometimes mentioned as a celebrity whose “gummy smile” is considered cute. It seems that her smile, which shows her gums, is seen as a unique part of her charm.
Of course, it’s not possible to medically diagnose a gummy smile based on a photo alone.
Cuteness isn't determined solely by how many millimeters of gum are visible. I think the overall atmosphere of the smile and the expression that reflects the person's unique personality are also important.
Why do people find a gummy smile unattractive?
One reason people may find a gummy smile unattractive is that it reflects others’ opinions or the gap between their actual smile and their ideal one.
Let's think about how we perceive smiles and how we deal with our insecurities.
Sometimes, how others see you and how you feel about yourself don't match up.
Even when people around you say, “You’re cute,” you still can’t help but be self-conscious about your mouth. Haven’t you had that kind of experience?
Some people might find it hard to smile when having their picture taken.
The aspects that others find attractive aren't necessarily the same as the ones you're self-conscious about. That's exactly why you don't need to force yourself to believe they're your best features.
Don't let negative words alone determine your smile
On the internet, you sometimes come across strong statements like, “A gummy smile is gross” or “A gummy smile isn’t cute.”
However, such terms are not medical assessments. They also reflect personal preferences and biases.
I don’t think the value of my smile is determined by what someone else says.
Of course, if you want to change the appearance of your mouth, it’s perfectly fine to value that desire.
Is the "gummy smile" more common in women? Here's why.
Haven't you heard that a "gummy smile" is more common in women?
In fact, there is research indicating that there are gender differences in how the gums appear.
A study published in 2022 examined the amount of gum visible when smiling among 120 men and women aged 20 to 40. The results indicated that women tended to show more of their upper gums [3].
It is thought that factors such as lip length, lip movement, and tooth position may play a role, but there is no single definitive reason.
Also, please note that this study involved a limited number of participants. It may not apply to all women.
What if you want to change the appearance of your gummy smile?
Regardless of whether others think it’s “cute” or not, some people may want to get closer to the smile they envision for themselves.
In that case, treatment for a gummy smile is one option.
For example, if the issue is caused by movement of the upper lip, we may consider Botox injections or lip repositioning (upper lip mucosal resection).
If the position of the gums is a factor, a procedure called aesthetic crown lengthening may be an option. Depending on the alignment of the teeth, orthodontic treatment may be the best approach.
However, simply reducing gum exposure isn't enough.
Whether or not the natural movement of the face when smiling can be preserved is also an important factor to consider when deciding on a procedure.

Frequently Asked Questions About the Charm of a Gummy Smile
Here are answers to common questions we receive from patients regarding the appearance of their smiles and treatment options.
Q1. How many millimeters of gum must be visible for it to be considered a "gummy smile"?
Generally, a guideline is that when you smile, your upper gums should be visible by at least 3 mm.
However, we do not base our judgment solely on numbers. We also consider the condition of the teeth, gums, and upper lip when determining whether treatment is necessary.
Q2. Is it okay not to treat a gummy smile?
If it's just a cosmetic issue, treatment isn't necessarily required.
However, this does not apply if you experience symptoms such as swollen gums or difficulty closing your mouth. If you have any concerns, please consult your dentist.
Q3. Is a reverse gummy smile cute? What does it look like?
The term “reverse gummy smile” refers to a condition in which the upper front teeth are not very visible when a person smiles.
Like a "gummy smile," this is a term used to describe the appearance of the mouth, and whether people find it cute varies from person to person.
Q4. Does changing the way you smile change the impression of a gummy smile?
Being mindful of how you move your lips can sometimes temporarily change how your gums appear.
However, this does not address the underlying cause of a gummy smile. Please also refer to our article explaining what you can do on your own and what your limitations are.
Q5. Will treating a gummy smile change the way my smile looks?
The impression your smile makes changes depending on how much of your gums are visible and how your upper lip moves.
However, the results may vary from person to person. During your consultation, please describe in detail the specific smile you’d like to achieve.
A gummy smile is just another way to express your unique smile
Is a gummy smile cute?
I don't think there's a single answer to that question that applies to everyone.
I don’t think it’s necessary to change the way you smile just to please those around you. That said, if you personally want to change, I’d like to respect that decision as well.
At BIANCA CLINIC, we assess the condition of your teeth, gums, and upper lip while considering the overall balance of your smile.
