Identifying the Cause of a Gummy Smile
A gummy smile can result from several different underlying causes, including excess gum tissue covering more of the tooth crown than usual, a short or hyperactive upper lip that lifts higher than normal during smiling, an upper jaw that has grown slightly too far vertically, or teeth that appear short due to delayed passive eruption where gum tissue never fully receded during development.
Correctly identifying which of these factors, or combination of factors, is responsible is essential, since each requires a different treatment approach. Your dentist will examine your smile at rest and at full smile, and may take measurements or refer for orthodontic or oral surgery input where jaw position is involved.
Gum Contouring for Excess Tissue
When excess gum tissue is the primary cause, a procedure called gum contouring or crown lengthening can reshape the gum line to expose more of the natural tooth crown, immediately creating a more balanced smile proportion. This can be performed using a scalpel, laser, or electrosurgery depending on the case and available technology.
This procedure is usually done under local anaesthetic and recovery is generally quick, with mild tenderness for a few days. Results are visible almost immediately once initial healing settles, making it one of the more efficient gummy smile corrections available.
Addressing Lip and Jaw Related Causes
If a hyperactive upper lip is the main cause, options range from a minor surgical procedure to limit the lip's upward movement to, in some cases, carefully considered use of a muscle-relaxing injection to reduce lip elevation temporarily, an option some dentists offer in coordination with appropriately qualified practitioners.
Where the underlying cause is excessive vertical growth of the upper jaw, correction may require orthodontic treatment or, in more significant cases, orthognathic jaw surgery, which is a more involved undertaking but can address both the gummy smile and any related bite issues at the same time.
Setting Realistic Expectations
Because gummy smiles often involve more than one contributing factor, a combination of treatments sometimes provides the best result rather than relying on a single procedure alone. Your dentist will explain honestly which factors are treatable with straightforward dental procedures and which may require referral to an orthodontist or oral surgeon.
We always recommend a thorough assessment before proceeding with any surgical or orthodontic option, since gum contouring alone will not resolve a gummy smile caused primarily by lip movement or jaw position, and setting the wrong expectation early can lead to disappointment.
Questions patients ask us
- Is gum contouring painful?
- The procedure itself is performed under local anaesthetic so it is not painful at the time, and most patients experience only mild tenderness for a few days afterwards, manageable with the pain relief we recommend.
- How long do gum contouring results last?
- Results from gum contouring for excess tissue are generally permanent, since the reshaped gum line does not typically regrow to its previous position, provided the underlying cause was purely excess soft tissue rather than jaw-related growth.
- Can braces fix a gummy smile?
- In cases where the gummy appearance is linked to tooth position or mild jaw discrepancies, orthodontic treatment can help improve the smile line, though it is not effective for gumminess caused purely by excess soft tissue or lip hyperactivity.
- Will my teeth look too short after gum contouring?
- No, the procedure is designed specifically to reveal the natural tooth crown that was previously covered by excess gum, so teeth typically appear at their proper natural length rather than unusually short.
