A gummy smile is when more gum tissue than usual shows above your upper teeth when you smile, often of visible gingival display. While it’s often a cosmetic concern, the causes of a gummy smile can also point to alignment or bite issues worth addressing. The good news? In many cases, yes, it can be fixed.
People of all ages have gummy smiles. Some have lived with one since childhood, while others notice changes as they get older. Either way, you’re not alone, and you have options.
At Moon Orthodontics, Dr. Joe Moon helps patients understand what’s behind their smile and what can be done about it.
What Is a Gummy Smile?
A gummy smile, also called excessive gingival display, happens when of gum tissue shows above your upper teeth as you smile. It’s usually a cosmetic concern, but it can also signal underlying alignment or jaw issues. Gummy smiles affect people of all ages and are treatable in many cases.
Some folks barely notice their gummy smile. Others feel self-conscious every time they laugh or pose for a photo. Both reactions are completely valid.
Here’s what to know:
- It’s more common than you might think
- It can affect kids, teens, and adults
- Causes range from genetics to tooth position
- Treatment depends on what’s causing it
What Causes a Gummy Smile?
Several factors can lead to a gummy smile, and identifying the cause is the first step toward fixing it. Often, more than one factor is at play. The most common causes of a gummy smile include:
- Excessive upper jaw growth
- A hyperactive upper lip
- Short or worn teeth
- Gums that didn’t recede properly during development
- Misaligned or protruding teeth
Let’s break down the main causes:
What Is Vertical Maxillary Excess?
This is a technical way of saying the upper jaw grew a little too much vertically. When the jaw is longer than average, more gum tissue naturally shows when you smile.
What Is a Hyperactive Upper Lip?
Some people have lip muscles that lift higher than typical when smiling. The lip itself may be normal in size, but it pulls up more, exposing extra gum tissue.
Do Short or Small Teeth Cause It?
If your teeth are shorter than average, your gums can look proportionally larger. This can be genetic or caused by years of grinding and wear.
What Is Altered Passive Eruption?
As baby teeth fall out and adult teeth come in, the gums should naturally recede to expose the full tooth crown. Sometimes that recession doesn’t happen completely, leaving extra gum tissue covering the teeth.
How Does Tooth Position and Alignment Affect It?
Teeth that protrude or sit at certain angles can push the gum line forward, making more gum visible. Bite issues like overbites can also contribute. These are some of the most fixable causes of a gummy smile.
How Does Orthodontic Treatment Fix a Gummy Smile?
When the cause involves tooth position, alignment, or bite issues, orthodontic treatment can make a real difference. Both metal braces and clear aligners can gently move teeth up into the jaw (called intrusion), which reduces how much gum shows when you smile.
Here’s how Dr. Moon approaches it:
- Tooth intrusion: Moving teeth slightly upward into the bone reduces gum display
- Bite correction: Fixing overbites or deep bites can change how your smile looks at rest and when smiling
- Alignment improvements: Straightening protruding teeth balances the gum line
- Combined care: Some cases benefit from orthodontics plus gum contouring or other care
Clear aligners and metal braces are both effective options, depending on your case. Dr. Moon will walk you through what would work best for you during your first visit, which includes a no-goop digital scan to map out your customized treatment plan.
For gummy smiles caused by skeletal or muscular issues alone, orthodontics may not be the full answer. That’s why a thorough evaluation matters. According to the American Association of Orthodontists , evaluating the cause is key to choosing the right treatment.
Benefits of Treating a Gummy Smile
Fixing a gummy smile isn’t just about aesthetics, though that’s a big part of it for many people. The benefits go deeper, touching how you feel and how your mouth functions day to day.
Does It Improve How Your Smile Looks and Feels?
When you treat the underlying cause, you get a more balanced smile where your teeth, gums, and lips work together in better proportion. Confidence climbs too. Smiling without thinking twice feels pretty great, and many patients find themselves laughing in photos again. Here’s what changes:
- A more balanced smile. Your teeth, gums, and lips line up in better proportion.
- Boosted confidence. Smiling without second-guessing feels freeing.
Many of our patients tell us they didn’t realize how much they were hiding their smile until they didn’t have to anymore.
How Does It Help Your Oral Health Long-Term?
Correcting alignment and bite issues makes brushing and flossing easier and protects your teeth for years to come. Lasting results follow naturally. When treatment addresses the root cause, the change sticks. Here’s the payoff:
- Better oral health. Easier cleaning and stronger protection against wear.
- Lasting results. Fixing the source keeps your new smile in place.
What Are the Gummy Smile Treatment Options?
Different causes call for different solutions. Here’s a quick look at the main options:
| Treatment | Best For | What It Does |
|---|---|---|
| Orthodontics (braces or clear aligners) | Alignment, bite issues, tooth position | Moves teeth into better position, intrudes teeth to reduce gum show |
| Gum recontouring | Excess gum tissue, altered passive eruption | Reshapes the gum line for a more balanced look |
| Lip repositioning | Hyperactive upper lip | Limits how high the lip lifts when smiling |
| Jaw correction | Significant vertical maxillary excess | Addresses skeletal causes of gum display |
The right option depends on what’s causing your gummy smile. In some cases, a combination works best. That’s why Dr. Moon takes time during your first visit to look at the bigger picture before recommending any treatment.
What Affects the Cost of Treatment?
The cost of treating a gummy smile depends on several factors, including the underlying cause, the treatment type, how long care will take, and what your insurance covers. A free consult at Moon Orthodontics gives you a personalized estimate so you know exactly what to expect.
What goes into the cost:
- The underlying cause. Simpler cases involving tooth position may need less treatment than skeletal causes.
- Treatment type. Clear aligners, metal braces, or combined care each have different price points.
- Length of treatment. Some cases take 6 months, others 18-24 months.
- Insurance and financing. Coverage varies, and we offer affordable treatment options to fit your budget.
We’ll go over all of this at your first visit. No surprises, just clear information.
Are You a Candidate for Treatment?
Most people with a gummy smile are candidates for some form of treatment, but the best approach depends on what’s causing it. Good candidates include teens and adults whose gummy smile stems from tooth position, alignment, or bite issues. Some patients may need a multidisciplinary approach combining orthodontics with other care.
You might be a great fit if:
- Your gummy smile is connected to misaligned or protruding teeth
- You have an overbite or deep bite contributing to gum display
- You’re looking for aesthetic improvement and better oral health
