A gummy smile occurs when excess gum tissue is visible above the upper teeth while smiling. While not a medical concern, some individuals feel self-conscious about the appearance of their smile and prefer a more balanced, proportionate look.
At Metropolis Dermatology in Costa Mesa, CA, we offer Botox® injections and other non-invasive treatments to relax the upper lip muscles, reducing excessive gum exposure for a more symmetrical and aesthetically pleasing smile.
What is a Gummy Smile?
A gummy smile is characterized by more than 3 to 4 millimeters of gum tissue showing when smiling. This condition affects smile symmetry and is influenced by muscle activity, tooth structure, and jaw alignment. While some people embrace their gummy smile, others prefer subtle enhancements to create a more balanced facial appearance.
Causes of a Gummy Smile
Several factors contribute to the appearance of a gummy smile, including:
- Hyperactive Upper Lip Muscles: Overactive lip muscles pull the upper lip higher than normal, exposing more gum tissue while smiling.
- Excess Gum Tissue: Some individuals naturally have more gum coverage over their teeth, making their gums more visible.
- Tooth Size & Eruption: Small or under-erupted teeth can make gums appear more prominent.
- Jaw and Lip Anatomy: A short upper lip, high lip line, or particular jaw structure can also influence the appearance of a gummy smile.
Identifying the underlying cause of a gummy smile is essential for selecting the most effective treatment. Botox® injections provide a simple, muscle-focused solution for many patients.
Symptoms of a Gummy Smile
The primary concern with a gummy smile is its cosmetic impact, though symptoms may include:
- Excess Gum Visibility: More than 3 to 4 millimeters of gum tissue shows when smiling.
- Imbalanced Smile Proportions: The gums appear more dominant than the teeth, creating an uneven smile.
- Self-Consciousness: Many individuals with a gummy smile feel less confident in photos or social settings and seek ways to enhance their smile.
How Botulinum Toxin Can Help with a Gummy Smile
Botox® offers a non-surgical solution for a gummy smile by relaxing the muscles responsible for excessive lip elevation:
- Targeted Injections: Botox® is precisely injected into the muscles that control lip movement, reducing excessive elevation while smiling.
- Muscle Relaxation: The Botulinum toxin weakens these muscles temporarily, allowing the upper lip to sit slightly lower, covering more gum tissue.
- Quick & Minimally Invasive: The procedure is fast, requires no downtime, and allows patients to resume daily activities immediately.
- Temporary but Effective: Results typically last 3 to 4 months, making Botox® a great non-permanent option for those exploring treatment.
This treatment is customized to individual anatomy and cosmetic goals, ensuring a natural-looking improvement.
