A confident smile can change the way you feel — and how others see you. But if you find yourself covering your mouth when you laugh or holding back a full grin because too much gum shows, you’re not alone. A “gummy smile” is one of the most common cosmetic dental concerns patients ask about, and the good news is that it’s very treatable.
This guide breaks down everything you need to know about gummy smiles: what causes them, which treatments actually work, and what to expect when you visit a dental professional.
What Is a Gummy Smile?
A gummy smile — clinically referred to as excessive gingival display — occurs when a noticeable portion of your gum tissue is visible above your upper teeth when you smile. Most dental professionals consider it a concern when four millimeters or more of gum tissue is exposed.
It’s worth noting that a gummy smile is not a sign of poor oral health. Rather, it’s an aesthetic issue that many people want to address for personal confidence reasons. Whether it’s mild or more pronounced, today’s dental and cosmetic treatments make it easier than ever to achieve a balanced, attractive smile.
What Causes a Gummy Smile?
Understanding the root cause matters a lot — because the most effective treatment depends entirely on why the gummy smile occurs in the first place. Common causes include:
- Excess gum tissue — The gums cover too much of the tooth surface, making teeth appear shorter than they actually are.
- Teeth that didn’t fully erupt — Sometimes teeth don’t fully emerge from the gum line, leaving more gum exposed.
- Hyperactive upper lip — In some people, the upper lip rises higher than normal during a smile, revealing more gum tissue.
- Jaw position or skeletal growth — If the upper jaw protrudes or is vertically longer than average, this can cause gum display.
- Medication side effects — Certain medications, especially those used to treat high blood pressure or seizures, can cause gum overgrowth.
Gummy Smile Treatment Options
There is no single fix for a gummy smile — but there are several excellent options, and a skilled dentist will recommend the one that fits your specific anatomy, goals, and budget.
1. Gum Contouring (Crown Lengthening)
For patients whose gummy smile is caused by excess gum tissue, gum contouring — also called a gingivectomy or crown lengthening — is one of the most direct and lasting solutions. During this procedure, the dentist carefully removes or reshapes excess gum tissue to expose more of the natural tooth crown.
The result is a more balanced gum-to-tooth ratio and a noticeably more attractive smile. Recovery is typically quick, and most patients see a dramatic improvement in a single appointment.
- Minimally invasive with laser or scalpel techniques
- Permanent results
- Can be combined with other cosmetic procedures
2. Botox Injections for Hyperactive Upper Lip
When the cause is a hyperactive upper lip — meaning the lip rises too high when you smile — Botox offers a surprisingly simple and effective solution. Small injections into the upper lip muscles temporarily relax the muscle, limiting how high the lip rises when you smile.
This is a minimally invasive option with no downtime. Results typically last three to six months and can be repeated as needed. Botox for gummy smiles is especially popular among patients who want to test a solution before committing to a more permanent procedure.
- Quick, in-office treatment — often under 15 minutes
- No surgery or recovery time
- Natural-looking results
3. Dental Veneers
If your teeth appear short because of how they’ve erupted — not necessarily because there’s too much gum — porcelain veneers can create the appearance of longer, better-proportioned teeth. Veneers are ultra-thin shells bonded to the front of the teeth to enhance shape, size, and color.
Veneers don’t address the gum itself, but they can create a visually balanced smile that significantly reduces the perceived gumminess. They’re an excellent choice for patients who also want to improve tooth color or symmetry at the same time.

4. Orthodontic Treatment
In some cases, the gummy smile is related to the positioning of the teeth or jaw. Invisalign or traditional braces can help by moving teeth into better positions, which in turn alters how much gum is visible. This is especially true when the bite is the underlying issue.

5. Orthognathic Surgery (For Skeletal Cases)
When a gummy smile stems from the underlying bone structure — such as an overgrown upper jaw — orthodontic or soft-tissue solutions alone may not deliver the desired result. In these more complex cases, orthognathic (jaw) surgery may be recommended in coordination with orthodontic treatment.
This is typically reserved for severe skeletal discrepancies and is performed by an oral and maxillofacial surgeon. While it involves a longer recovery, the results can be transformative for the right candidate.
Which Treatment Is Right for You?
The best approach depends on the underlying cause. Here’s a quick overview to help set expectations:
| Cause | Recommended Treatment | Invasiveness |
| Excess gum tissue | Gum contouring / Crown lengthening | Minimally invasive |
| Hyperactive upper lip | Botox injections | Non-invasive |
| Short-looking teeth | Dental veneers | Minimally invasive |
| Bite / tooth position | Invisalign / Orthodontics | Non-surgical |
| Skeletal jaw excess | Orthognathic surgery | Surgical |
Your dentist will evaluate several factors during a consultation — including the amount of gum exposure, lip mobility, tooth length, and jaw alignment — to recommend the most appropriate treatment plan.
What to Expect During a Gummy Smile Consultation
If you’re curious about treatment, the first step is a thorough dental evaluation. During your consultation at Miracle Dental, the team will:
- Review your dental and medical history

Combining Gummy Smile Treatment with Other Cosmetic Procedures
Many patients choose to address a gummy smile as part of a broader smile transformation. Once gum tissue is properly contoured, the reveal of more tooth surface opens up additional cosmetic possibilities:
- Teeth whitening to brighten the newly exposed enamel
- Dental bonding to refine the shape of teeth
- Veneers for a complete aesthetic overhaul

Frequently Asked Questions About Gummy Smile Treatment
In most cases, a gummy smile is a cosmetic concern rather than a dental health issue. However, if gum overgrowth is caused by a medication or gum disease, it’s important to address the underlying cause with your dentist.
Yes — procedures like gum contouring and crown lengthening offer permanent results. Botox injections are temporary (lasting a few months) but can be maintained with periodic touch-ups.
Most gummy smile treatments are performed with local anesthesia, so you should feel little to no discomfort during the procedure. Some mild soreness or swelling is normal afterward, especially with gum contouring, but typically resolves within a few days.
Most patients recover from gum contouring within one to two weeks. During this period, you’ll want to eat soft foods and follow your dentist’s aftercare instructions. Swelling and mild discomfort are common but manageable.
A consultation with a dental professional is the best way to find out. Your dentist will examine your gum tissue, teeth, lip movement, and jaw structure to identify the root cause and recommend the most effective option for your situation.
Yes — for patients whose gummy smile is caused by a hyperactive upper lip, Botox is a well-established, effective treatment. It temporarily limits lip elevation when smiling, reducing gum exposure. Results typically last three to six months.
