What Makes a Smile "Gummy"
If your smile shows more gum than tooth, you have what's called a "gummy smile." This means that when you smile, your upper lip rises higher than ideal, exposing an excessive amount of your gum tissue.
There's nothing wrong with a gummy smile from a health perspective. It's purely cosmetic. But if it bothers you, modern dentistry offers several effective solutions. The best approach depends on what's causing your gummy smile—sometimes it's the gum itself, sometimes it's the teeth, and sometimes it's how your lips move when you smile.
Why Smiles Can Look Gummy
There are several reasons your smile might show a lot of gum:
Excess Gum Tissue: Your body simply produced more gum tissue than average. Your teeth are actually a normal size, but they're covered with extra gum. This is the most common cause. Short Teeth: Sometimes your teeth genuinely are shorter than average, making it look like gums are excessive even when the amount of gum is normal. Your Upper Lip Movement: Some people's upper lips are very mobile and rise high when smiling. Even if the amount of visible gum is technically normal, the movement makes it seem excessive. Jaw Position: In rare cases, the upper jaw is positioned lower than ideal (a skeletal issue), naturally showing more gum. Combination: Many people have a combination—some extra gum plus some tooth shortness plus significant lip movement.

This determines which solution will work best for you.
Gum Contouring (Gingivectomy)
This is the most common approach for excess gum tissue.
Your cosmetic dentist carefully removes excess gum tissue using a laser or surgical instruments, reshaping the gum line to show more of your teeth and less of your gums. The goal is a natural-looking gum line that frames your teeth beautifully.
How It Works: The procedure is straightforward. After numbing the area, your dentist uses either a soft-tissue laser or a scalpel to precisely remove excess gum. The laser vaporizes the tissue cleanly, while surgical instruments cut it. The dentist carefully contours the gum line to create a natural shape. How It Feels: You feel pressure and vibration but no pain because the area is completely numbed. There's no bleeding because the laser seals blood vessels, or the dentist uses special instruments that minimize bleeding. After Contouring: The area looks slightly raw for a few days but heals quickly. You might have mild soreness, similar to scratching your gum with your toothbrush. Most people return to eating soft foods by day 2-3 and normal eating by day 5-7. Results: You immediately see more of your teeth and less gum. The change is dramatic and obvious. The new gum line typically looks natural and well-proportioned to your face. Permanence: Gum contouring results are permanent. The gum tissue that was removed doesn't grow back.Lengthening Teeth (Crown Therapy)
If your teeth are naturally short or if gum covers too much of the tooth surface, your cosmetic dentist might recommend crowns.
New crowns can be designed to show more tooth surface and less gum. This makes the teeth look longer and the smile less gummy.
Advantages: If your teeth need cosmetic restoration anyway (due to old fillings, staining, or damage), crowns solve multiple problems at once—they lengthen the teeth, improve color, and improve shape. Disadvantages: Crowns require preparing the tooth surface, which means removing some of your natural tooth. They also cost more than gum contouring alone. But they last 10-15 years or longer. Results: Your teeth look longer, more prominent, and more proportional to your face. The gummy appearance significantly improves.Lip Repositioning
If your upper lip rises too much when you smile (hypermobile lip), your cosmetic dentist might suggest a muscle relaxing injection or, rarely, surgical lip repositioning.
Botox for Lips: A small amount of Botox injected into the muscles that elevate your upper lip limits how high the lip rises when you smile. This reveals less gum without changing your teeth or gum tissue. Results are temporary (lasting 3-4 months), but the injections are quick and painless. Surgical Lip Repositioning: Rarely, if Botox doesn't achieve enough correction, a surgeon can surgically reposition the lip muscles to limit lift. This is more invasive and permanent but provides dramatic correction.Orthodontic Correction
In some cases, especially if you have jaw positioning issues, orthodontics might be part of the solution.
Braces or clear aligners can intrude (move downward) your upper teeth slightly, which can reduce how much gum is visible. This approach takes 12-24 months but is very effective for certain types of gummy smiles.
Combination Approaches
Most people benefit from a combination strategy:
- Gum contouring to remove excess tissue
- Crown therapy to make the teeth look longer
- Botox to limit upper lip movement
The Ideal Gum Exposure
Cosmetic dentists have standards for what looks ideal. Generally:
- Showing 1-2 millimeters of gum in a natural smile is considered ideal
- Showing 3-4 millimeters is still acceptable
- Showing more than 4 millimeters is generally considered "gummy"
Timeline and Recovery
Immediately After: Your gums might be slightly swollen and sensitive. Days 1-3: Mild soreness (like a mouth scrape). Most people can return to work. Days 3-7: Swelling resolves. Most people return to normal eating. Week 1-2: Healing is essentially complete. Weeks 2-4: The gum line is completely healed and the result is fully visible. After 1 Month: The final result is stable and will remain permanent.If you had Botox, you'll see improvement over days 3-7 as it takes effect, with maximum effect by week 2.
Before and After Smile Design
Modern cosmetic dentistry uses digital smile design technology to show you exactly what your smile will look like after treatment. Your dentist can take a photo of your smile and digitally modify it to show:
- How much gum will be visible
- What your new gum line shape will be
- How your teeth will look
- Overall smile proportions
Cost Considerations
- Gum contouring alone: $500-$1,500
- Crown therapy: $1,000-$3,000 per tooth
- Botox injections: $200-$400
- Lip repositioning surgery: $2,000-$4,000
Long-Term Stability
Gum contouring results are permanent—the removed tissue doesn't grow back. Crown results last 10-15 years or longer. Botox effects fade after 3-4 months and require repeat injections.
Many people are thrilled with their gum contouring results for decades. It's one of the most permanent cosmetic dental procedures.
Will My Teeth Look Longer
Yes. Removing gum tissue that was covering your teeth reveals more of the tooth surface, making teeth look longer. If you also get crowns, the effect is even more dramatic because the crowns can actually be designed longer than your natural teeth were.
This is usually exactly what you want in a gummy smile correction. Longer-looking teeth generally look more youthful and esthetic.

Conclusion
A gummy smile is purely cosmetic and doesn't affect your oral health. But if it bothers you, several effective solutions exist. Gum contouring removes excess tissue for immediate, permanent results.
Crown therapy lengthens teeth and improves their appearance. Botox limits upper lip movement with temporary but reversible results. A combination approach often works best. Modern cosmetic dentistry can redesign your smile to show the ideal amount of gum—usually just 1-2 millimeters—creating a more balanced, esthetic smile you'll love.
> Key Takeaway: Gum contouring removes excess gum tissue to reveal more of your teeth and create a more balanced smile. The procedure is quick, healing is rapid, results are immediately visible and permanent. Most people achieve their ideal smile with gum contouring alone or combined with other cosmetic approaches like crowns or Botox.
