If you find yourself holding back your smile in photos, or feeling self-conscious every time you laugh out loud, you are not alone. A gummy smile, where an excess of gum tissue makes the teeth appear shorter than they should, is one of the most common cosmetic dental concerns we hear about from patients in Sydney’s CBD.
The good news is that it is also one of the most treatable. Modern cosmetic dentistry offers several safe and effective approaches to gummy smile correction, and results can be genuinely life-changing for those who have spent years hiding their smile.
This article explains what causes a gummy smile, how teeth lengthening and gum treatment works, and what you can expect from the process.
What Exactly Is a Gummy Smile?
A gummy smile occurs when too much gum tissue is visible above the upper teeth during a smile. Most dental professionals consider a gum display of more than three to four millimetres above the teeth to be a gummy smile, though what looks proportionate varies from person to person.
In many cases, the teeth themselves are a perfectly normal length; they just appear short because excess gum tissue is covering part of the crown. This is where teeth lengthening and gum treatment becomes relevant. By carefully removing or reshaping that excess tissue, more of the natural tooth surface is revealed, creating a more balanced and proportionate smile.
What Causes a Gummy Smile?
There are several reasons why someone might show more gum than they would like. The most common cause is a condition called altered passive eruption, where the gum tissue does not recede fully as the adult teeth emerge, leaving the teeth looking shorter than they are.
Other contributing factors can include:
A hyperactive upper lip that rises higher than normal when smiling. Overgrowth of the upper jaw, which causes the gums to appear enlarged. Certain medications that cause gum tissue to thicken. Genetics, which simply means some people are naturally predisposed to a fuller gum line.
Understanding the underlying cause matters because it determines which treatment approach will deliver the best result. A proper assessment with an experienced cosmetic dentist is always the first step.
How Does Teeth Lengthening Gum Treatment Work?
Teeth lengthening for a gummy smile is most commonly achieved through a procedure known as a crown lengthening procedure or gum contouring. These terms are sometimes used interchangeably, though they can differ slightly in scope.
During gum contouring, the dentist removes or reshapes the excess gum tissue to expose more of the tooth’s surface. In a full crown lengthening procedure, bone tissue may also be gently reshaped to ensure the new gum line remains stable over time.
Both approaches are performed under local anaesthetic, so you remain comfortable throughout. The level of complexity depends on how much tissue needs to be adjusted and whether bone involvement is required.
Laser Gum Lift: A Modern Alternative
Many patients today opt for a laser gum lift, which uses a precise dental laser to remove and reshape gum tissue instead of a scalpel. A laser gum lift in Sydney CBD is increasingly popular because it tends to involve less bleeding, a reduced risk of infection, and a faster, more comfortable recovery compared to traditional surgical methods.
Healing time varies depending on the extent of the treatment, but most patients find that gum lift recovery time is relatively manageable, typically a week to two weeks before the gum line fully settles. Mild sensitivity and some swelling in the first few days are normal and usually well-managed with over-the-counter pain relief.
Who Is a Good Candidate for a Gum Lift?
Gum lift candidates are generally adults in good overall oral health who feel that their gum line is disproportionate to their teeth. Any existing gum disease or decay must be treated before cosmetic gum reshaping is considered.
Ideal candidates tend to be people who:
Feel self-conscious about showing too much gum when smiling or laughing. Have teeth that appear short or stubby despite being structurally sound. Are you looking for a minimally invasive cosmetic solution with lasting results? Want to improve smile symmetry and overall facial aesthetics?
If you are unsure whether you qualify, a consultation will allow your dentist to assess your gum line, tooth proportions, and underlying jaw structure to determine the most appropriate treatment plan.
Gum Lift vs Veneers: Which One Do You Need?
A question that comes up often is whether a gum lift or veneers would better address a gummy smile. The honest answer is that it depends entirely on your individual anatomy and goals.
Porcelain veneers are thin shells placed over the front surface of the teeth. They are excellent for improving the shape, colour, and length of teeth, and they can sometimes create the appearance of a more proportionate smile. However, if the underlying issue is excess gum tissue rather than short teeth, veneers alone will not fully resolve a gummy smile.
In some cases, a combination of cosmetic gum reshaping followed by veneers delivers the most complete aesthetic result. In others, a gum lift alone is all that is needed. This is why personalised assessment matters; there is no one-size-fits-all answer.

What Does a Gum Lift Cost in Sydney?
Gum contouring cost in Australia varies depending on the extent of the treatment, the number of teeth involved, and whether a laser or surgical approach is used. As a general guide, a cosmetic gum lift for multiple teeth in Sydney will typically range from several hundred to a few thousand dollars.
Because this is a cosmetic procedure, it is generally not covered by Medicare. Some private health funds may provide a partial rebate under extras cover, particularly if there is a clinical component such as crown lengthening to support restorative work. It is always worth checking with your fund before your appointment.
During your consultation, your dentist will provide a detailed, itemised treatment plan so you know exactly what to expect before committing to any procedure.
What to Expect: Gum Lift Before and After
Most patients are genuinely surprised by how much difference a gum lift makes to the overall appearance of their smile. Even small changes to the gum line can dramatically alter the perceived length and proportion of the teeth, making the smile look more natural, balanced, and aesthetically pleasing.
Before your procedure, your dentist will often show you a visual preview of the expected outcome so you can feel confident going in. After the procedure, as the gum tissue heals and settles over the following weeks, the full result gradually becomes visible.
Gum lift before and after photos can give a helpful sense of what is achievable, but keep in mind that individual results depend on your unique anatomy and the skill of your treating dentist.

Practical Tips for a Smooth Recovery
Recovery from a gum lift is generally straightforward. To support healing and protect your results, keep the following in mind:
Eat soft foods for the first few days and avoid anything hard, sharp, or excessively hot. Keep the area clean by gently rinsing with warm saltwater as directed. Avoid smoking, as it significantly slows gum healing. Attend any scheduled follow-up appointments so your dentist can monitor the healing process.
Most patients return to normal daily activities within a day or two, though the gum tissue itself continues to heal for several weeks.
Final Thoughts
A gummy smile is something many people feel deeply self-conscious about, yet it is a condition that can often be corrected with a straightforward, minimally invasive procedure. Whether the right approach is a laser gum lift, a crown lengthening procedure, or a combination of treatments, the key is understanding your options and getting the right professional advice from the start.
Addressing excess gum tissue earlier rather than later also means you can enjoy the benefits of a more proportionate, confident smile for longer, and in some cases, it can support the long-term health and stability of your teeth and gums.
