Beyond the Gums: How Orthodontic Treatment Can Fix a Gummy Smile
When you look in the mirror and smile, do you feel like your gums take center stage? A “gummy smile”—clinically known as excessive gingival display—is a common aesthetic concern. While many people believe this is strictly a dental or periodontal issue, the truth is that the most effective, long-term solutions often start with an orthodontist.
At MacKenzie Orthodontics, we help patients in Saint John, Quispamsis, and St. Stephen understand that a gummy smile is usually about the relationship between your teeth, your jaw, and your lips. Here is how orthodontic treatment can transform your smile balance.
What Causes a Gummy Smile?
Before we can fix it, we have to identify why it’s happening. Common causes include:
- Vertical Maxillary Excess (VME): This is when the upper jaw bone is longer than average, causing the entire dental arch to sit lower.
- Abnormal Tooth Eruption: Sometimes teeth appear short because they didn’t fully emerge from the gum tissue, even though the teeth themselves are a normal length.
- Hyperactive Upper Lip: If the muscles that control your upper lip are too strong, they may pull the lip up too high when you laugh or smile.
- Bite Issues: An “overbite” or “deep bite” can cause the upper teeth to be positioned in a way that pushes the gum tissue forward and downward.
- Short Upper Lip: In some cases, the upper lip is simply shorter in length, meaning it cannot physically cover the gum line as effectively as a longer lip would.
- Gingival Hypertrophy (Overgrowth): This is an actual overgrowth of the gum tissue itself, which can sometimes be caused by certain medications, systemic health factors, or even poor oral hygiene while wearing braces.
- Tooth Wear and Compensatory Eruption: If teeth are worn down over time due to grinding (bruxism), they may “erupt” further to maintain a biting surface, bringing the gums down along with them.
The Orthodontic Approach to Correction
While a “gum lifts” (gingivectomy) treats gingival overgrowth and Botox treats a hyperactive lip temporarily, orthodontic treatment addresses the structural root cause.
1. Intrusive Mechanics with Braces or Invisalign
One of the most effective ways we treat a gummy smile is through “intrusion.” By using specific wires in traditional braces or precisely engineered Invisalign aligners, we can gradually move the upper teeth upward into the jawbone. As the teeth move up, the gum line naturally follows, reducing the amount of tissue visible when you smile.
2. Temporary Anchorage Devices (TADs)
For more significant cases, we may use TADs. These are tiny, biocompatible “mini-screws” placed temporarily in the bone. They act as a fixed anchor point, allowing us to apply a steady upward force to the entire upper arch. This is a highly effective, non-surgical alternative to jaw surgery for many patients.
3. Correcting the Bite
By fixing an overbite or adjusting the tilt of the upper teeth, we can change the way the lip drapes over the gums. Properly aligned teeth often “fill out” the smile more effectively, making the gums appear much less prominent.
4. Orthognathic Surgery to Address VME
Sometimes the bone discrepancy is very large and only jaw surgery can correct the cause of the gummy smile. In that case, we send you for a consultation with an oral and maxillofacial surgeon so they can assess and provide you with all the options. Keep in mind that the surgery happens together with orthodontic treatment.
A Life-Changing Transformation
Choosing an orthodontist in Southern New Brunswick to treat your gummy smile means you are looking at the “big picture.” We don’t just look at the gums; we look at your facial symmetry, your profile, and your long-term dental health.
When your teeth and jaws are in their ideal positions, the “gumminess” often disappears naturally, leaving you with a balanced, confident smile that feels as good as it looks.
