A beautiful smile is all about balance and facial harmony. When your teeth, gums, and lips are in balance, they create a naturally attractive and confident appearance. But when too much gum tissue shows above the upper teeth, even if the teeth themselves are perfectly healthy, it can make the smile look uneven or the teeth appear smaller than they are. This is what’s commonly known as a gummy smile.
While it’s not a medical issue, many people feel self-conscious about how a gummy smile affects their overall appearance. The teeth may feel hidden or out of proportion, especially in photos or while speaking.
But what causes a gummy smile, and what are the options for correcting it? Let’s take a closer look.
What is a Gummy Smile?
A gummy smile is when too much gum tissue shows above the upper teeth when you smile. It’s most often noticed when the gumline extends lower than average, making the teeth appear shorter.
There isn’t a strict standard for what qualifies as a gummy smile, but many dentists consider it noticeable if more than 3 to 4 millimetres of gum is exposed. It’s not a health issue, but it can affect how a smile looks and how a person feels about it.
In most cases, the teeth are completely healthy. The concern is cosmetic. When the gums dominate the smile, it can throw off the natural balance between the teeth, gums, and lips. That’s why many patients choose to have it assessed and treated.
What Causes a Gummy Smile?
There are a few different reasons why a gummy smile can develop:
- Your gum tissue covers too much of your teeth, making them appear shorter.
- Your upper jaw is longer or more prominent, causing more gum to show.
- Your upper lip lifts too high when you smile, revealing more of the gum line.
- Your teeth didn’t erupt fully, which can leave more of the crown hidden beneath the gum.
Understanding the cause is the first step to choosing the most suitable treatment. Your dentist can assess your smile and guide you toward the right solution.
Why Do People Choose to Fix a Gummy Smile?
Excessive gum display can make the teeth appear short and disrupt the overall balance of the smile. Many patients seek treatment to achieve better proportions between their teeth and gums, thereby feeling more confident when smiling or speaking.
For others, it’s part of a broader cosmetic plan, especially when combined with veneers or other restorative work. Regardless of the reason, treating a gummy smile can have a noticeable impact on both aesthetics and self-esteem.
What Treatments Are Available for a Gummy Smile?
Gummy smile treatments aren’t one-size-fits-all. The best option depends on what’s causing the excess gum exposure. Here are five effective options dentists use to reduce the appearance of excessive gum:
- Gum Shaping (Laser Gum Contouring): Gum shaping involves removing excess gum tissue using a precise dental laser. It’s often used when healthy teeth are partially hidden by overgrown gum, making them appear shorter. The laser gently trims and sculpts the gum line to expose more of the natural tooth. The procedure is performed under local anesthesia, and most people return to normal activities within one to two days.
- Dental Veneers: Porcelain veneers are custom-made ceramic covers that are bonded to the front of teeth. When teeth are short, uneven, or have cosmetic flaws, veneers can improve their size and shape to balance your smile. They don’t remove gum tissue, but can be paired with gum contouring for a more dramatic effect.
- Orthodontic Treatment: If your gummy smile is related to the position of your teeth or how your bite fits together, orthodontic treatment such as braces or Invisalign might help. By moving teeth into better alignment, this option can reduce gum display in a gradual, long-term way.
- Crown Lengthening: This is a minor surgical procedure that removes both gum and small amounts of bone to uncover more of the tooth’s structure. It’s typically used when teeth haven’t fully erupted or are structurally short.
- Anti-Wrinkle Injections: When a hyperactive upper lip lifts too high while smiling, small doses of muscle relaxant (like botulinum toxin) can reduce its movement. This is a temporary, non-invasive solution to improve smile balance.

Things to Keep in Mind Before Choosing a Treatment
While treatments like gum contouring, porcelain veneers, and anti-wrinkle injections can significantly improve the appearance of a gummy smile, not every case is straightforward. Some individuals may need more advanced procedures, like lip repositioning surgery or orthodontic correction, depending on the structure of their gums, teeth, and jaw.
The right treatment for you will depend on factors like the severity of gum display, the underlying cause, and your aesthetic goals. Every smile is unique, and so is every treatment plan.
Can a Gummy Smile Be Corrected?
Yes, a gummy smile can be improved with the right treatment. The solution depends on what’s causing the extra gum visibility, whether it’s too much gum tissue, smaller-looking teeth, or the way the upper lip moves when you smile.
At Perfect Smile in Adelaide, we focus on conservative, cosmetic options such as laser gum contouring and porcelain veneers. These treatments are designed to bring out the natural proportions of your teeth and create a more balanced, confident smile.
