Gummy Smile Treatment Auckland
Gummy Smile Treatment in Auckland
A gummy smile — where an excessive amount of gum tissue is visible when you smile — is one of the most common aesthetic concerns that brings patients to an orthodontic specialist. It is also one of the most misdiagnosed and mistreated. The right treatment depends entirely on correctly identifying the cause, and the cause is not always what it appears to be.
Dr Adith Venugopal has published peer-reviewed research specifically on gummy smile aetiology and treatment. At Parnell Orthodontics, every gummy smile case begins with a thorough diagnostic process — not an assumption — and the treatment recommended is the most conservative, stable option available for your specific situation.
What causes a gummy smile?
There are three broad categories of cause, and they require very different treatments.
A dental cause occurs when the teeth appear short because they have not fully erupted from the gum — a condition called altered passive eruption. In these cases, the teeth are actually a normal length but are partially covered by excess gum tissue. Laser or surgical gum recontouring can expose the full tooth surface, instantly improving the appearance of the smile with minimal orthodontic involvement.
A skeletal cause occurs when the upper jaw has grown excessively in a vertical direction — known as vertical maxillary excess. This pushes the gum line downward and increases the amount of gum displayed during smiling. Mild to moderate cases can be corrected using TAD-based orthodontic mechanics to intrude the upper front teeth. Significant skeletal cases may require orthognathic jaw surgery, typically in combination with orthodontic treatment.
A muscular cause occurs when the upper lip elevates excessively during smiling due to hyperactive lip elevator muscles, exposing more gum than normal even when the teeth and jaw are in normal positions. This is a soft-tissue issue and is typically managed outside of orthodontics.
Can a gummy smile be fixed without surgery?
Many gummy smiles can. For cases where the cause is dental or involves moderate vertical excess, TAD-based intrusion mechanics allow Dr Adith to push the upper front teeth upward into the bone, effectively reducing the amount of gum visible during smiling without any jaw surgery. This is one of the most clinically demanding applications of orthodontic TADs, and one that requires genuine expertise in biomechanics to plan and execute correctly. Dr Adith is among the most published researchers in this specific area internationally.
For patients who have been told surgery is their only option, a specialist assessment at Parnell Orthodontics is worth obtaining before making that decision.
What does gummy smile treatment involve?
The process begins with a comprehensive assessment including photographs, 3D scanning, and where clinically indicated, CBCT imaging to evaluate the position of the teeth roots and the bone available for movement. From this, Dr Adith establishes the cause of the gummy smile and maps out the most appropriate treatment pathway. This is communicated clearly in writing and in person before any treatment begins.
Treatment duration depends on the nature and severity of the case. TAD-based orthodontic correction typically takes 12 to 18 months. Surgical cases involve a pre-surgical orthodontic phase, the surgery itself, and a post-surgical settling phase.
