A gummy smile is a condition where, when smiling, the upper gums are excessively exposed (usually more than 3mm from the gum line to the upper lip). This is not a disease but rather an aesthetic imbalance between three elements: teeth, lips, and gums.

What causes a Gummy Smile?

It is rarely just one thing. A gummy smile is usually the result of a “tug-of-war” between your teeth, your lips, and your jawbone.

  • Hyperactive Upper Lip: The muscles that control your upper lip are a bit “overachievers.” When you smile, they pull the lip up higher than average, exposing the gums.
  • Vertical Maxillary Excess (VME): This is a fancy way of saying the upper jawbone is simply longer than average.
  • Gingival Hyperplasia: This is when the gum tissue is overgrown. Your teeth might be the perfect size, but they are “hiding” under too much gum.
  • Altered Passive Eruption: The teeth didn’t fully erupt from the bone and gum tissue during childhood, making them appear “short” or “square.”

Yes, absolutely. Categorize treatments:

  • Non-Surgical (Temporary): Botox or Fillers can relax the lip or add volume to hide the gums.
  • Micro-Invasive (Permanent): Laser Gingivectomy (Gum Contouring). This uses a laser to “trim” and reshape the gum line. It’s painless and heals in days.
  • Surgical (Permanent): Lip Repositioning Surgery. This is a minor procedure that “tucks” the inside of the lip so it cannot physically lift as high when you smile.
  • Orthodontic/Orthognathic: If the issue is bone-related, braces, Invisalign, or jaw surgery can reposition the entire dental arch upward.
