Many people suffer from what is known as a “gummy smile”, which is a condition that makes the appearance of the smile not harmonious due to the exposure of a large part of the gums when smiling. And although this condition does not cause direct health damage, it may affect self-confidence and the overall aesthetic impression, especially in social or professional meetings.
Fortunately, treatments for gummy smile have developed significantly, to include non-surgical solutions and other surgical or precise cosmetic options that can make a clear difference without pain or long recovery periods.
What is a gummy smile?
A gummy smile is a condition in which a large part of the upper gums appears clearly when smiling, which gives the impression that the teeth are shorter or not proportional with facial features.
Aesthetic standards of the perfect smile
A balanced smile shows the upper teeth in a proportionate ratio with the lips and gums. The normal amount of gum exposure should not exceed approximately 2 mm when smiling fully. Any increase beyond that may be classified as a gummy smile.
Difference between a gummy smile and a natural smile
In a natural smile:
- The upper third of the front teeth appears
- The upper lip covers most of the gums
In a gummy smile:
- A large part of the upper gums appears, which disrupts the natural harmony between teeth and lips
Causes of gummy smile
Differences in tooth development:
Sometimes, the way your permanent teeth grow can lead to a gummy smile. Although this varies from person to person, a small study conducted in 2014 found that it may be a family trait.
If your gums cover a larger part of the surface of your teeth when they erupt – a condition called altered passive eruption – it may lead to a gummy smile.
If the teeth in the front of the mouth grow too long or excessively, the gums may have grown excessively as well. This condition is known as dentoalveolar extrusion.
A gummy smile can also occur due to a condition called vertical maxillary excess. This happens when the upper jaw bone grows longer than normal.
Lip differences:
A gummy smile can occur when the upper lip is short. And if your lips are very mobile – meaning they move a lot when you smile – they may expose more of the gum line.
Medications:
Some medications can cause your gums to grow excessively around your teeth. This is known as gingival overgrowth, such as medications that prevent seizures, suppress the immune system, or treat high blood pressure, which can cause gum overgrowth.
In this case, it is important to treat the condition. If not treated, gum overgrowth can lead to gum disease.
Diagnosis of gummy smile
Diagnosis of gummy smile depends on a comprehensive evaluation of the condition by a specialized dentist.
Measuring gum exposure ratio
The dentist measures the distance between the upper lip edge and the gum line during smiling, and analyzes the extent of tooth coverage.
Analyzing tooth occlusion
The shape of the smile is closely related to the occlusion between the upper and lower jaws. Any occlusal disorder may cause or increase the appearance of a gummy smile.
3D imaging
3D imaging is used to accurately visualize bones and teeth, and determine whether there is maxillary protrusion or tooth positioning issues.
Lip movement assessment
The upper lip muscles and their movement during speaking and smiling are examined. Some cases are due to hyperactivity of the lip muscles, not a gum or tooth problem.
Latest gummy smile treatment methods
There is no one solution that fits all. The choice of gummy smile treatment depends on the main cause of the condition.
1- Conservative treatments:
Invisible orthodontics (Invisalign): used to gently move teeth and reduce their protrusion, which reduces the visible gum area.
Botox injections (temporary effect 4–6 months): Botox is injected into the upper lip muscles to reduce their movement when smiling. It is considered a non-surgical and fast-result option.
Gum laser (gum reshaping): laser is used to remove excess gum tissue without surgery and improve the appearance of the gum line. It is an effective option for those who suffer from excess gum length rather than short teeth.
2- Surgical treatments:
Upper jaw surgery: if the cause of the gummy smile is maxillary protrusion, surgery can be performed to adjust the jaw position.
Gum removal (gingivectomy): also known as “clinical crown lengthening”, where excess gum tissue is removed to expose more of the teeth.
Upper lip repositioning: used in cases of excessive upper lip movement, where tissues are repositioned to reduce movement and improve harmony.
Jaw orthognathic surgery: if the jaw is part of the cause of excessive gum display, the dentist or oral surgeon may recommend corrective surgery. This procedure balances the length of the upper and lower jaws.
Lip repositioning surgery: this is done by removing a portion of the connective tissue from the underside of the upper lip. This prevents the lifting muscles in the lip and nose area from raising the upper lip above the teeth.
3- Cosmetic treatments:
Ceramic veneers (to visually lengthen teeth): dental veneers can be used to make teeth appear longer, balancing tooth length and gum exposure.
Filler injections (to improve lip harmony): fillers are used to enhance the upper lip and adjust its position, thereby covering part of the gums when smiling.
Laser procedure steps (gum reshaping)
Laser treatment is considered one of the most popular modern methods for treating gummy smile without pain or surgery.
- Local anesthesia: the gums are fully numbed to avoid any sensation of pain during the procedure
- Determining excess gum amount: a preliminary line is drawn to define the ideal gum line level
- Laser removal of tissue: the laser precisely cuts excess tissue without bleeding or sutures
- Shaping the new gum line: the gums are reshaped to match the natural tooth contour
- Final polishing: the laser is also used to smooth tissues and prevent inflammation after the session
The result is usually immediate, and the patient can see the change in the smile right after completion.
Conclusion
A smile is an inseparable part of human self-confidence, and a gummy smile should not be an obstacle for you. With the advancement of medicine and the emergence of non-surgical gummy smile treatments such as laser or Botox, it has become possible to restore facial aesthetic balance easily and safely.

FAQs
What are the real causes of gummy smile, and are there non-surgical solutions?
Gummy smile (gingival display) results from several factors: either hyperactivity of the upper lip muscles, short tooth crowns, or maxillary bone protrusion. Currently, we provide very effective non-surgical solutions; such as Botox injections to relax the upper lip and prevent excessive elevation, or laser gum reshaping that removes excess tissue in one session without traditional surgery.
What is the difference between laser gum contouring and traditional surgery?
Traditional surgery relies on scalpel and sutures, causing swelling and long recovery. At Wonders Dentistry, we use soft tissue laser; the laser cauterizes tissues while cutting, meaning no bleeding or pain, and healing starts immediately. The patient can return to normal life the same day with a completely new smile.
Can gummy smile be treated by orthodontics only?
Yes, in certain cases. If the cause is tooth positioning or mild jaw protrusion, orthodontics or Invisalign can reposition teeth upward. Sometimes we use mini orthodontic anchors (TADs) to help lift the teeth and gums together, avoiding complex jaw surgery.
Does the gum grow back after removal surgery?
When the procedure is performed precisely and professionally at Wonders Dentistry, laser gum contouring results are permanent in most cases. We measure the “biological width” to ensure only excess tissue is removed while preserving healthy supporting tissue, preventing recurrence in the future.
