Gummy Smile in NYC? Why Do My Gums Show So Much When I Smile?
A gummy smile describes what you see, not why it happens. Extra gum coverage, lip movement, tooth position, jaw proportions, or swollen/enlarged tissue can all increase visible gum display.
Teeth look short
Extra gum coverage is only one possible explanation.
Lip rises high
Muscle movement can create gum display even when gums are healthy.

A gummy smile is often completely healthy. There is no universal amount of visible gum that every person needs to correct. Treatment is elective when the gums, teeth, and supporting tissues are healthy and the concern is aesthetic.
20-SECOND EXPLANATION
What Does Gummy Smile Actually Mean?
Clinicians often call it excessive gingival display: more upper gum tissue is visible during smiling than the patient prefers.
01
It is an appearance description.
Healthy gums can show prominently. The term does not automatically mean gingivitis or periodontitis.
02
Different causes can look almost identical
Short looking teeth may be covered by gum, actually worn, naturally small, or surrounded by enlarged tissue.
03
The cause determines the treatment
Removing gum tissue does not fix a lip-mobility or skeletal cause, and orthodontics does not remove excess gum tissue.
COMMON SMILE PATTERNS
What Does Excess Gum Display Look Like?
These patterns can overlap and do not diagnose the cause on their own.
Gums show above all front teeth
A broad band of healthy-looking tissue is visible when smiling.
Teeth look short or square
Natural crowns may be partly covered, or the teeth may truly be shorter from wear or development.
Upper lip rises very high
Everything may look normal at rest, but much more gum appears during a broad smile.
Uneven gumline
Some teeth show more gum than others.
Puffy gums cover more tooth
Inflamed or enlarged tissue can make normal teeth look shorter.
Gum display plus bite differences
Tooth position or skeletal relationships may be part of the smile pattern.
CONDITION-SPECIFIC INFOGRAPHIC
Why Does My Smile Show So Much Gum?
Five pathways can create a similar-looking smile, and more than one can occur together.
Extra gum coverage
More of the natural crown may remain covered by gum tissue.
Upper lip moves higher
Lip length or muscle activity may expose more gum during a broad smile.
Upper-jaw proportions
A vertically greater maxillary relationship can increase gingival display.
Tooth position or bite
Selected positions can move the gumline lower relative to the lip.
Gum enlargement or inflammation
Puffy or overgrown tissue can cover more tooth structure.
The Same Smile Can Need Completely Different Care
A soft-tissue issue, hypermobile lip, tooth-position issue, and skeletal proportion should not all be treated with the same procedure.
Not every case needs gum removal
Removing tissue only makes sense when tissue itself is a major contributor.
Not every case needs orthodontics
Aligners or braces only address selected tooth-position and bite factors.
Not every case needs treatment
Healthy gum display can be left alone if the patient is comfortable.
AESTHETIC FINDING VS GUM DISEASE
Gummy Smile Is Not the Same as Gingivitis or Periodontitis
One describes how much gum you see. The others describe inflammation or loss of tooth supporting tissues.
More Gum Can Show Without Disease
Pink, firm, stable gums can be completely healthy even when prominent during smiling.
- No routine bleeding, swelling, or drainage.
- Stable periodontal support.
- Any treatment is primarily elective and aesthetic.
Red, Puffy, or Bleeding Tissue Needs a Health Check
Plaque-associated gingivitis or other gingival enlargement can cover more tooth surface. Periodontitis is a separate disease affecting deeper supporting tissues.
- Bleeding, swelling, plaque, and pocketing may be present.
- Medication-related enlargement is possible.
- Health issues should be stabilized before elective reshaping.
RELATED CONDITIONS NOTE
If your main concern is bleeding or periodontal inflammation, use the Bleeding Gums or Gum Disease pathway.

TRUSTED CLINICAL GUIDANCE
Why Diagnosis Matters Before Cosmetic Gum Treatment
Excessive gingival display is widely described as multifactorial in clinical literature.
Authoritative references
The American Academy of Periodontology explains that some gummy smiles occur because normal-length teeth are covered by excess gum tissue and that crown lengthening can reshape gum and bone. Cleveland Clinic explains that gum contouring planning also considers lip position, tooth wear, oral health, and bone structure. StatPearls lists several distinct causes of excessive gingival display.

Cleveland Clinic - Gum Contouring
PubMed / StatPearls - Excessive Gingival Display
WHEN THE GUMS ARE NOT THE MAIN CAUSE
Lip Movement, Tooth Position, and Jaw Proportions Can Matter
Removing tissue cannot solve every gummy smile.
Upper-Lip Movement
Selected patients show more gum because the upper lip elevates strongly. Botulinum toxin may be used by appropriately trained clinicians in selected muscle-related cases, but the effect is temporary and does not change the gums, teeth, or jaw.
- Not appropriate for every cause.
- No fixed duration should be promised.
- This page does not confirm current DDD availability of botulinum toxin treatment.
Tooth Position or Skeletal Proportions
Selected tooth-position causes may improve through orthodontic movement, while significant skeletal causes may need specialist assessment.
- Clear aligners or braces can address selected tooth-position problems.
- Orthodontics does not remove excess gum tissue.
- More significant skeletal cases may require interdisciplinary consultation.
SMILE EVALUATION
How Does a Dentist Evaluate a Gummy Smile?
The goal is to identify which structure is contributing before discussing a procedure.
MIXED CAUSES NOTE
Periodontic, orthodontic, or oral-maxillofacial input may be useful in more complex cases.
Start with goals and medical history
Review medications, gum history, previous orthodontics, and whether the appearance changed recently.
Compare the smile at rest and in motion
Lip length, elevation, and the pattern of gum display are considered.
Measure tooth proportions and gum health
Clinical crown height, gum contour, inflammation, pocketing, and tissue thickness help identify soft-tissue contributions.
Check tooth position and bite
Alignment and eruption position are considered before orthodontic treatment is proposed.
Assess supporting bone when appropriate
Dental imaging or specialist records may be used when bone position or skeletal relationships could affect planning.
TREATMENT DEPENDS ON THE CAUSE
What Can Be Done About a Gummy Smile?
There is no universal best treatment. The safest plan targets the structure creating the gum display.
HEALTHY EXCESS SOFT TISSUE
Gum Contouring / Gingivectomy
Selected soft-tissue cases may be treated by reshaping excess gum when periodontal anatomy allows.
GUM + BONE RELATIONSHIP
Crown Lengthening
Selected patients may need a periodontal procedure that reshapes gum and sometimes supporting bone to expose a more natural crown.
MUSCLE / LIP MOBILITY
Temporary Muscle-Relaxing Treatment
Botulinum toxin may temporarily reduce upper-lip elevation in selected muscle-related cases when administered by an appropriately qualified clinician.
TOOTH POSITION / BITE
Orthodontic Movement
Clear aligners or braces may help selected tooth-position causes.
INFLAMMATION / ENLARGEMENT
Gum-Health Treatment First
Plaque control, professional cleaning, and periodontal care come before elective contouring when gums are inflamed or enlarged.
TOOTH-SIZE / WEAR COMPONENT
Cosmetic Restorative Planning
Bonding or veneers may alter tooth proportions in selected cases, but they do not treat lip hypermobility, skeletal causes, or active gum disease.
KEEP THE GUMS HEALTHY
What Can You Safely Do at Home?
Home care can reduce plaque-related swelling, but it cannot change lip movement, jaw proportions, or safely remove gum tissue.
Helpful habits
- Brush twice daily with fluoride toothpaste and a soft-bristled toothbrush.
- Clean between teeth daily.
- Keep professional cleaning and periodontal follow-up on the schedule recommended for your risk level.
- If gum enlargement began after a prescription change, tell both the dentist and prescribing clinician.
- Monitor new bleeding, swelling, tenderness, or rapid tissue enlargement.
What home care cannot do
- It cannot diagnose altered passive eruption or bone position.
- It cannot reposition the upper lip or change skeletal proportions.
- It cannot orthodontically intrude or reposition teeth.
- Never cut, burn, scrape, or chemically push back gum tissue at home.
- Do not stop or alter prescription medication without medical guidance.
WHEN GUM DISPLAY IS MORE THAN COSMETIC
When Should Enlarged or Puffy Gums Be Checked Promptly?
A stable healthy gummy smile is usually not urgent. Rapid overgrowth, bleeding, pain, swelling, drainage, or mobility is different.
Rapid gum enlargement
New overgrowth over weeks or months deserves a dental and medication review.
Frequent or spontaneous bleeding
Persistent bleeding is a gum-health concern, not simply cosmetic.
Swelling, pus, drainage, or fever
These findings may accompany active dental or periodontal infection.
Newly loose or shifting adult teeth
Mobility can indicate periodontal support loss or trauma.
Gum change after starting a medication
Do not stop the medicine yourself; coordinate with the prescribing clinician and dentist.
Rapid facial swelling or difficulty breathing/swallowing?
Seek emergency medical care immediately.

Common Questions
Questions Patients Ask About Gummy Smiles
Possible contributors include extra gum coverage, strong upper-lip elevation, tooth position, upper-jaw proportions, and gingival enlargement. More than one factor can occur together.
Not necessarily. Many gummy smiles are healthy anatomical variations. Redness, swelling, bleeding, or support loss is a separate health concern.
They may be normal-length teeth partly covered by gum, actually worn down, naturally smaller, or surrounded by enlarged tissue.
It can help selected soft-tissue cases, but not every cause. Lip movement, tooth position, bone position, and gum health must be assessed first.
Dental crown lengthening is a periodontal procedure that can reshape gum and, when needed, underlying bone to expose more natural tooth structure.
Botulinum toxin may temporarily reduce excessive upper-lip elevation in selected muscle-related cases. It does not remove gum tissue, move teeth, or change the jaw.
Clear aligners can help selected tooth-position or bite-related contributors, but they cannot treat every soft-tissue, lip-mobility, or skeletal cause.
Yes. Gingival inflammation or enlargement can cover more tooth surface and should be treated as a gum-health issue before cosmetic reshaping.
Some prescription medications can contribute to gingival enlargement. Do not stop the medication yourself; discuss the change with the prescribing clinician and dentist.
Yes. Upper-jaw proportions can contribute to gingival display in some patients. More significant skeletal cases may need orthodontic or specialist assessment.
No. Some cases need no treatment; others may involve periodontal, orthodontic, muscle-related, or specialist options depending on the cause and patient goals.
Arrange prompt evaluation for rapid gum enlargement, frequent bleeding, significant swelling, drainage, fever, pain, or newly loose adult teeth.
