What Is a Gummy Smile?
A gummy smile is characterized by the visible display of an excessive amount of upper gum tissue—typically more than 3 to 4 millimeters—when smiling. While completely harmless from a health perspective, it can throw off the aesthetic balance between the lips, gums, and teeth. Factors such as lip movement, tooth size, and natural anatomy all play a role in how much gum is exposed.
What Causes a Gummy Smile?
Several anatomical and genetic factors may contribute to the presence of a gummy smile:
- Overactive Upper Lip Muscles
Muscles that control the upper lip may be hyperactive, pulling the lip too far upward when you smile. - Extra Gum Tissue
Some individuals naturally have a larger amount of gum covering their teeth, leading to more visibility when smiling. - Short or Small Teeth
When teeth are undersized or have not fully erupted, the ratio of gum to tooth can make the gums appear dominant. - Facial and Jaw Structure
A short upper lip, a high lip line, or the positioning of the jaw may also enhance gum exposure.
Pinpointing the specific cause of your gummy smile allows our Pasadena team to tailor treatment using Botulinum toxin to produce the most flattering results.
Signs You May Have a Gummy Smile
Not sure if what you’re seeing qualifies as a “gummy” smile? Here are a few signs:
- Noticeable Gum Exposure
More than 3–4 millimeters of gum tissue shows above your teeth when you smile. - Smile Imbalance
The gums may overpower the teeth, giving your smile an uneven or disproportionate look. - Self-Consciousness or Insecurity
Some individuals with a gummy smile feel less confident in photos or avoid smiling widely.
How Botox® Injections Can Improve a Gummy Smile
At Metropolis Dermatology in Pasadena, we use precise Botulinum toxin injections to subtly adjust the upper lip’s movement and reduce gum show.
Here’s how the treatment works:
- Targeted Placement
Small amounts of Botox®, Dysport, or Jeuveau are injected into the muscles that elevate the upper lip too far. - Lip Relaxation
The treatment relaxes the targeted muscles just enough to allow the upper lip to sit lower when smiling, concealing more of the gums. - Non-Surgical + Quick
This approach doesn’t require downtime or anesthesia and can be done in a few minutes during your visit. - Temporary and Adjustable
Most patients enjoy results for around 3 to 4 months, making this an ideal trial for those not ready to commit to surgical options.
Our providers customize the injection technique to suit your facial anatomy, ensuring the outcome looks natural—not frozen or overcorrected.
