A gummy smile happens when too much gum shows when your child smiles. It is common and often nothing to worry about, but many parents wonder whether their child will outgrow it or if it needs treatment. In this blog, we will discuss whether a gummy smile improves on its own or if you need treatment to fix it.
What Causes a Gummy Smile in Children?
There are a few possible reasons why your child might have a gummy smile:
- Natural growth–Young children often have short clinical crowns and a higher upper lip.
- Small teeth or extra gum tissue–Naturally small teeth can make gums look more prominent.
- Overactive upper lip muscle–The upper lip lifts higher than average when smiling.
- Jaw growth–Upper jaw grows longer vertically, showing more gum even with normal tooth and lip anatomy.
- Genetics–Often runs in families and may be normal for that child’s facial type.
Can Children Outgrow a Gummy Smile?
In many cases, yes. As children grow and their adult teeth come in, the proportions of their face and smile change. As the face elongates and permanent teeth erupt. This can naturally reduce gum show and make the smile look more balanced.
However, not every child will outgrow it. If the cause is related to jaw growth or lip movement, you may need to see a dentist or an orthodontist. They can diagnose the cause behind a gummy smile and provide potential treatment options.
Why Early Checkups Matter
Even if a gummy smile seems like only a cosmetic issue, it can sometimes signal other problems, such as:
- Misaligned jaws
- Improper tooth eruption
- Mouth breathing or airway issues
It is best to take your child for a check-up by age 7. Dentists will confirm whether it is just a phase or a growth consequence. Once the cause is diagnosed, you can get it treated in the early years when your child’s jaw is still developing.
Treatment Options for Gummy Smile
Note that most cases improve naturally. Some treatment descriptions (like veneers and gingivectomy) are not typical for children. If your child doesn’t outgrow the gummy smile, possible treatments include:
Behavioral & Airway Management
If mouth breathing contributes, treat allergies or nasal obstruction.
Orthodontic Guidance
Appliances like bite blocks, growth modification, or braces later on can address jaw-related causes.
Lip Repositioning Surgery
This is a minor surgery where the dentist will adjust the upper lip to prevent it from lifting too high. This procedure is administered under local anesthesia and takes a few minutes to complete.
Gum Contouring
It gently reshapes the gum line for a balanced look. It is often done with a laser or special dental tools to remove tiny areas of gum tissue for a more balanced and symmetrical smile. It is completed in a single visit.
Final Word
A gummy smile is when more gum than usual is showing when smiling. In many children, it improves naturally as they grow. However, if it doesn’t change over time, you might need to consider dental treatments to correct it. Some common treatments include gingivectomy, gum contouring, veneers, and lip repositioning surgery.
