Understanding Gummy Smiles: What They Are and Why They Happen 

Are you revealing too much gum when you smile? That’s called a gummy smile , and it’s a common dental problem that can influence both how you look and how confident you feel. Medically called excessive gingival display, it is a dental condition when more than 3–4 millimeters of gum tissue is visible above your upper teeth when smiling. 
For more than 10 years, our dentists, Dr. Tommy Song and Dr. Joon Cho in Frisco Clinic , have been diagnosing and treating gummy procedures at Smile Lounge in Frisco, TX, using methods that are safe and effective.  

What Is a Gummy Smile? 

A gummy smile occurs when the gums show excessively due to a variety of reasons, including hyperactive upper lip muscles, altered tooth eruption, short teeth, or jaw-related issues. For patients seeking cosmetic or functional improvement, understanding the underlying cause is key. 

How “gummy” you think your grin is depends a lot on your taste. But you should realize that it’s not that unusual.

What Causes Excessive Gum Growth? 

Identifying the root cause helps determine the best gummy smile treatment. The most common causes are: 

  • Hyperactive Upper Lip Muscles – When you smile, your upper lip goes up too high. 
  • Short or Partially Erupted Teeth—Teeth may appear small, making gums more prominent. 
  • Excess Gum Tissue (Gingival Overgrowth)—This might happen because of heredity or drugs. 
  • Jaw Position (Vertical Maxillary Excess)—If the upper jaw grows too much, it might make the gums stand out more. 
  • Genetic Factors—Some people are born with teeth that are smaller or gums that are longer. 

Understanding what causes a gummy smile ensures the correction method is both safe and effective. 

Medically Approved Gummy Smile Treatments 

At Smile Lounge, we offer clinically validated Gum lift procedures. Each treatment targets a specific cause and is safe when performed by licensed professionals. 

1. Botox for Gummy Smile 

Botox for a gummy smile is a non-surgical treatment that works well for those with overactive upper lip muscles. 

How it works: Botox relaxes the muscles that pull the top lip up too high for a brief time, which makes the gums less apparent. 

Benefits : 

  • Quick procedure (10–15 minutes): Get your treatment done in a matter of minutes. 
  • Minimal downtime: Get back to your daily routines right away. 
  • Effective for mild to moderate gummy smiles: Provides noticeable improvement without surgery. 
  • Results last 3–4 months: Enjoy a balanced smile for several months. 

2. Laser Gum Contouring (Gingivectomy)

For smiles caused by excess gum tissue, laser gum contouring is highly effective. 

How it works: A dental laser modifies the shape of the gums so that more of the tooth surface is visible, which makes a smile that is even and balanced. 

Benefits: 

  • Minimally invasive: Gentle on gums with precise laser technology. 
  • Precise and quick: Allows for accurate reshaping in one session. 
  • Fast recovery (1–2 weeks): Heal quickly and comfortably. 
  • Ideal for: Patients needing gummy smile correction due to overgrown gum tissue. 

3. Orthodontic Treatment (Braces or Invisalign) 

Orthodontic treatment addresses gummy smiles corrections caused by crooked teeth or jaw issues. 

How it works: It slowly moves teeth into the right position, which makes your smile look better and your bite stronger. 

Benefits: 

  • Long-term results: Correct your smile permanently over time. 
  • Non-surgical: Stay away from procedures that need cutting. 
  • Corrects mild skeletal discrepancies: Improves alignment of teeth and bite. 
  • Ideal for: Patients wondering how to fix a gummy smile caused by misaligned teeth or eruption issues. 

4. Crown Lengthening

People with small teeth or changed passive eruption should get crown lengthening.

How it works: The dentist takes away a little piece of gum and sometimes bone to show more of the tooth’s natural crown.

Benefits: 

  • Permanent results: Long-lasting improvement to your smile. 
  • Improves gum-to-tooth ratio: Achieve better aesthetics and proportion. 
  • Enhances smile aesthetics: Makes teeth appear longer and balanced. 
  • Ideal for: Patients asking how to get rid of a gummy smile due to short teeth. 

5. Orthognathic (Jaw) Surgery

For severe skeletal causes like vertical maxillary excess, orthognathic surgery is the gold standard. 
How it works: A maxillofacial surgeon repositions the upper jaw to balance gum display and facial aesthetics. 

Benefits: 

  • Permanent solution: Corrects skeletal gummy smiles permanently. 
  • Corrects both function and appearance: Improves bite and aesthetics simultaneously. 
  • Can improve bite alignment: Enhances overall dental function. 
  • Ideal for: Patients with extreme gummy smiles not treatable by non-surgical methods.

Based on the type of treatments used, the treatments vary, like:

  • Botox: 3–4 months, minimal downtime
