A gummy smile, clinically known as excessive gingival display, refers to a condition where an unusually large amount of gum tissue is visible above the upper teeth when smiling. Dental professionals typically define it as showing 3–4 mm or more of gum beyond the crown of the teeth, a threshold beyond which smiles may be perceived as “gummy”.
This condition is more common than many realize. Several studies estimate that around 10% of adults, particularly those aged 20–30, are affected by a gummy smile. In this age group, women tend to experience it at higher rates than men, partly due to anatomical differences in lip movement and gingival display.
While a gummy smile poses no health risks, the aesthetic concern it raises can deeply affect self-esteem and confidence for many individuals. This blog post aims to delve into the roots of gummy smiles from muscular hyperactivity and dental eruption patterns to structural factors and to guide you through the full spectrum of treatment options, including Botox for gummy smile, surgical procedures, and minimally invasive techniques. Whether you're exploring gummy smile treatment options or curious about gummy smile celebrities who have openly discussed their experiences, we'll provide clarity and actionable insights.
What Exactly Is a Gummy Smile? The Aesthetic That Bothers Millions
A gummy smile, clinically known as excessive gingival display, is characterized by the visibility of 3–4 mm or more of gum tissue above the upper teeth when smiling. Dental professionals commonly use this quantitative threshold, typically more than 2–3 mm, to distinguish between a standard and gummy smile.
From a clinical standpoint, a gummy smile isn’t a disease; it’s an aesthetic diagnosis based on gum exposure. In healthy adults, approximately 2 mm of gum is considered standard. Anything beyond that may be considered excessive. However, individual perception varies, and what feels “too gummy” depends on facial proportions and personal preference.
Aesthetic & Psychological Impact
While medically benign, a gummy smile often carries emotional and confidence implications. Many individuals find it embarrassing or feel self-conscious, particularly in social and professional environments where smiling is important. Excessive gingival display can make teeth appear shorter, disrupting facial balance and leading some to avoid smiling openly.
Why It Matters
Facial Harmony: A smile displaying too much gum can upset the visual balance between teeth, lips, and gums, indicating a mismatch in facial proportions.
Patient Concerns: Many people associate a gummy smile with being less attractive or youthful, prompting them to pursue cosmetic corrections for confidence and self-esteem.
Defining a gummy smile hinges on visibility; more than 3 mm of gum beyond the upper teeth is generally regarded as excessive. Though not a health issue, its impact on facial aesthetics and personal confidence is significant, prompting many to seek corrective options.
Why Do Gummy Smiles Happen? 4 Root Causes Dentists Look For
A gummy smile, or excessive gingival display, can originate from several underlying factors: muscular, dental, skeletal, or gingival. Below is a breakdown of the primary causes:
Hyperactive Upper Lip Muscles: A hyperactive upper lip is often the most common cause. In this scenario, strong lip elevator muscles, especially the levator labii superioris and levator labii superioris alaeque nasi, lift the upper lip higher than usual during smiling. This action exposes more gum tissue than normal. Lip mobility measurements exceeding 6–8 mm are typical in such cases.
Excessive Gum Tissue (Gingival Hypertrophy): Gingival hypertrophy refers to overgrown gum tissue that drapes over the teeth. Common triggers include genetics, poor oral hygiene, mouth breathing, hormonal changes (e.g., during puberty or pregnancy), and medications like antiepileptics, immunosuppressants, or calcium channel blockers. In such cases, the teeth appear shorter, and smiling brightens more than intended.
Altered Tooth Eruption: Some individuals experience altered passive eruption or dentoalveolar extrusion, where teeth either do not fully emerge or gum and bone cover more teeth than normal. This results in shorter-looking crowns and an increased gingival display during a smile.
Vertical Maxillary Excess (VME): Vertical maxillary excess is a skeletal condition where the upper jawbone (maxilla) grows downward excessively. This leads to a “long-face” appearance, with gums exposed far beyond the standard 3–4 mm threshold, even without additional factors. Often, VME requires more comprehensive intervention, like orthognathic surgery.
Why Multiple Factors Matter
Many gummy smile cases involve a blend of these causes. For instance, an individual might have both a hyperactive lip and gum overgrowth, or VME, accompanied by altered eruption. Accurate diagnosis via clinical exams, lip mobility measurements, X-rays, and dental evaluation is vital to determine the right treatment approach.
How to Fix a Gummy Smile - Proven Treatments That Work
Treatments for a gummy smile fall into two main categories: non‑surgical and surgical. Each option addresses different causes and varies in invasiveness, recovery time, and permanence.
Non‑Surgical Treatments
1. Botox Injections
How it works: Botox (botulinum toxin) is injected into the upper lip elevator muscles, particularly the levator labii superioris and levator labii superioris alaeque nasi to partially paralyze them, reducing lip elevation during smiling.
Procedure: Quick (10–15 minutes), with minimal discomfort and virtually no downtime. Results begin to appear within a few days to two weeks and last about 4–6 months.
Ideal candidates: Best suited for those with a hyperactive upper lip and healthy gums, without structural dental or jaw issues.
Side effects: Temporary redness, swelling, mild bruising, upper lip tightness, asymmetry, difficulty speaking or drinking, and rarely, ptosis or dysphagia.
2. Lip Repositioning Surgery
What it does: A strip of tissue is removed from behind the upper lip, and then the lip is sutured lower to partially restrict muscle pull, thereby covering more gum.
Procedure and recovery: Typically done under local anesthesia in under an hour. Patients often return to work in 2–4 days, with most swelling, bruising, and tightness resolving within two weeks.
Results: More permanent than Botox but can relapse in rare cases.
Risks: Includes swelling, bruising, infection, temporary asymmetry, lip tightness, and possible recurrence.
Surgical Treatments
1. Crown Lengthening (Gum Lift)
What it corrects: Removes excess gum (and sometimes bone) to expose more of the tooth crowns, improving the gum-tooth ratio.
Procedure: Under local anesthesia, incisions are made, gum tissue (and possibly bone) is reshaped, and tissue is repositioned. Recovery involves sutures (removed in 1–2 weeks) and final impressions around 4–8 weeks later.
Ideal for: Individuals whose gummy smile results from excessive gingival tissue or altered eruption rather than lip hyperactivity or skeletal issues.
Risks: Post-op tenderness, swelling, modified crown-to-root ratio, and a healing period of several months. Maintaining hygiene is essential to prevent complications.
2. Orthognathic Surgery
When needed: Effective for cases of vertical maxillary excess (VME), where the upper jaw bone grows excessively, extending gum exposure beyond soft tissue or dental solutions.
Procedure: Includes Le Fort I maxillary impaction (raising the upper jaw) or bimaxillary surgery, often combined with orthodontic treatment.
Recovery: Requires general anesthesia, hospital stay, and extended healing time. Results in permanent structural correction and improved facial harmony.
Risks: Includes infection, nerve damage, relapse, and typical major surgery considerations.
Choosing the Right Treatment Path
Cause
Recommended Treatment
Hyperactive lip muscles
Botox → Lip repositioning
Excessive gum tissue/short teeth
Crown lengthening (± bone recontouring)
Altered tooth eruption
Crown lengthening +/– orthodontics
Vertical maxillary excess (skeletal)
Orthognathic surgery
Many cases involve mixed causes, e.g., a hyperactive lip plus excess gum tissue so a combination approach can yield optimum results.
A comprehensive diagnosis, including clinical exams, dental imaging, and lip mobility assessment, is essential for selecting the most effective and personalized treatment plan.
From fast and non-invasive options like Botox to permanent structural corrections via jaw surgery, there is a tailored gummy smile treatment for every case. The optimal path depends on a precise diagnosis of the underlying causes.
Botox for Gummy Smile: Fast, Painless, and Surprisingly Effective
Botox offers a minimally invasive, quick, and effective way to reduce a gummy smile by targeting muscle movement rather than altering bone or gum tissue.
Mechanism
Botox (botulinum toxin type A) works by blocking the release of acetylcholine at neuromuscular junctions, which reduces contraction of the upper lip elevator muscles, primarily the levator labii superioris, levator labii superioris alaeque nasi, and sometimes the zygomaticus minor. This limits how much the upper lip lifts, thus decreasing visible gum exposure when smiling.
Procedure
Injection sites: Typically, small doses are injected bilaterally 3 mm lateral to the alar-facial groove near the nose into the key lip elevator muscles.
Duration: The entire session takes 10–15 minutes and causes minimal discomfort.
Onset: Users typically notice improvement within two weeks, though some reports suggest results begin as soon as 4–7 days.
Effectiveness
Clinical studies indicate a significant reduction in gum recession on average, a 2–4 mm improvement, peaking at two weeks.
A notable study saw a 99.6% improvement in the gingival display two weeks post-treatment in 23 female patients.
Results last between 3–6 months, gradually diminishing without fully reverting to baseline at three months.
Considerations
Temporary results: Since muscle activity returns after several months, repeat treatments are required to maintain effects.
Candidate suitability: Ideal for individuals with a hyperactive lip and no underlying dental or skeletal causes; those with gum enlargement, altered tooth eruption, or vertical maxillary excess may need additional interventions.
Side effects: Rare and mostly mild include slight bruising, asymmetry, and temporary difficulty with lip movement or speech if improperly injected.
Contraindications: Not recommended for individuals with neuromuscular diseases (e.g., myasthenia gravis), certain allergies, pregnancy, or those taking specific medications; clinician assessment is essential.
Botox provides a safe, fast, and effective non-surgical option for mild to moderate gummy smiles driven by muscular overactivity. It's best suited to those seeking quick results with minimal downtime, provided they have the right clinical profile and realistic expectations about longevity and required follow‑up.
Celebrities With Gummy Smiles: Who Fixed Theirs and How?
Celebrities often face the same aesthetic concerns as anyone, gummy smiles included. Here are some notable public figures who’ve addressed (or openly experienced) excessive gingival display:
Meghan Trainor
Pop star Meghan Trainor underwent a Botox lip flip aimed at enhancing her smile. However, the procedure backfired: she reported that she "could not smile properly", with her face feeling stiff when attempting to express herself. She later cautioned fans that "nobody warned me" about this possibility, sharing that it taught her how important her natural smile is in lighting up a room.
Other Celebrities
Some public figures are known for their gummy smiles but have embraced or enhanced them in different ways:
Nicole Kidman, Gwen Stefani, and Katie Couric have been cited for having gummy smiles that they either subtly control or have treated through cosmetic dentistry, gum contouring, or laser procedures.
Jennifer Garner, Jon Heder, Anna Paquin, and Cobie Smulders have also been recognized for their gummy smiles. Some fans even speculated they've had minor corrective procedures like veneers or gum reshaping.
Why It Matters
Awareness & normalization: When celebrities openly discuss or show their gummy smiles, whether untreated or after cosmetic enhancement, it helps normalize concerns and reduces stigma.
Highlighting options: Their high-profile cases demonstrate a range of solutions, from subtle adjustments to full procedures like gum contouring.
Transparency on risks: Meghan Trainor’s candid remarks stress that even “simple” cosmetic treatments carry risks and that patient education and injector expertise are crucial.
Gummy smiles are common, even among the famous. Some choose to correct them through dental or cosmetic intervention, while others wear them confidently. Celeb stories, particularly Meghan Trainor’s lip flip experience, underscore the importance of knowing both the benefits and the potential downsides before undergoing any procedure.
The Road to a Confident Smile: Steps to Get Rid of Gummy Gums

What Could Go Wrong? Side Effects and Risks You Should Know
When addressing a gummy smile, both non-surgical and surgical treatments carry potential risks. Understanding and planning for these can help ensure a safe and satisfying outcome.
Botox Injections: Common Side Effects
Botox is considered a safe, minimally invasive procedure, but like any injection, it comes with temporary side effects:
Bruising and swelling at the injection site are often mild and resolve within a few days.
Redness, tenderness, or skin bumps near the treated area.
Temporary upper lip weakness, heaviness, or awkward movement, particularly with pronunciation, sipping, or puckering, as the lip muscles adjust to Botox.
Rare complications may include asymmetrical smile, drooping lip, numbness, or spread of paralysis to nearby facial muscles; these usually resolve as the toxin wears off.
Some patients report mild systemic symptoms like headaches, flu-like feelings, or nausea.
Mitigation Tip: Choosing a qualified, experienced injector dramatically reduces risk. Follow post-care guidelines such as avoiding strenuous activity, rubbing, and massaging for at least 24 hours.
Surgical Procedures: Potential Risks
Crown Lengthening (Gum Contouring)
Infection at the surgical site is rare, but is more likely with poor oral hygiene or smoking.
Bleeding and swelling are typically mild and manageable with proper care.
Increased tooth sensitivity to hot or cold due to exposed root surfaces.
Gum recession or bone loss may occur if excessive tissue removal impacts tooth stability, which can sometimes require gum or bone grafting.
Scarring or uneven healing may affect aesthetics if tissue removal is asymmetrical.
Orthognathic & Lip Repositioning Surgery
Infection, bleeding, scarring, and complications from anesthesia are inherent to any surgery.
Lip surgery may also cause temporary pain, bruising, swelling, and minor asymmetry visible during recovery.
Jaw surgery carries more serious risks like nerve damage, prolonged swelling, altered sensation, and rare relapse of the corrected position.
Post-Treatment Care: Crucial for Recovery
Adhering to aftercare instructions is mandatory for minimizing complications and optimizing results:
Botox: Avoid vigorous exercise, touching or massaging the area, alcohol, and lying down for several hours. Keep clean and hydrated.
Surgery: Follow prescribed medications, use ice packs, maintain a soft-food diet, and avoid smoking or alcohol; maintain oral hygiene as directed.
Follow-up care: Attend scheduled visits to monitor healing, check for infection, assess cosmetic results, and apply touch-ups if needed.
Both Botox and surgical methods are effective at reducing gummy smiles, but they carry distinct risks:
Botox: Temporary and less invasive, with side effects like swelling or temporary weakness that fade within weeks.
Surgery: More definitive results, but involves longer recovery and risks like infection, sensitivity, or scarring.
The best approach depends on the cause and desired permanence. Always consult a qualified specialist, understand possible complications, and follow aftercare meticulously for safe and lasting outcomes.
