Can Orthodontic Treatment Fix a Gummy Smile? What Are Your Options?

Braces can improve a gummy smile when the cause is dental — specifically, when the upper front teeth have over-erupted (moved too far downward) and the orthodontist can use intrusion mechanics to move them back upward. This physically raises the gum line relative to the upper lip, reducing gum show when smiling. However, if the gummy smile is caused by a structurally long upper jaw (vertical maxillary excess), an overactive upper lip muscle, or simply a short upper lip, braces cannot change these features and other treatments — jaw surgery, Botox, or lip repositioning — are needed instead. A specialist orthodontic assessment with X-rays is required to determine the cause and the appropriate treatment.

A gummy smile can be caused by several different factors: over-erupted upper front teeth (the teeth have moved too far downward, lowering the gum line); a long upper jaw bone (vertical maxillary excess), which is a skeletal cause; an overactive upper lip muscle that pulls the lip unusually high when smiling; a short upper lip that cannot cover the gum line; or altered passive eruption, where excess gum tissue has not receded to its normal level and covers too much of the tooth crown. Each cause requires a different treatment approach, which is why an accurate diagnosis is essential before pursuing any treatment.

The best treatment depends on the cause. For over-erupted upper teeth, orthodontic intrusion using braces or aligners — sometimes with temporary anchorage devices (TADs) — can be highly effective. For excess gum tissue covering the teeth (altered passive eruption), crown lengthening or gingivectomy performed by a periodontist can expose more of the tooth crown. For an overactive upper lip, Botox injections into the lip elevator muscles can temporarily reduce gum display. For a structurally long upper jaw, orthognathic surgery is the most effective permanent solution. Many patients benefit from a combination of approaches. A specialist orthodontist is the best starting point for a diagnosis and referral to the right colleagues.

Invisalign and other clear aligner systems can address a gummy smile when the cause is dental — specifically, when orthodontic intrusion of the upper front teeth is appropriate. Clear aligner systems have improved significantly in their ability to deliver intrusion mechanics, though some cases still require fixed appliances or temporary anchorage devices (TADs) to achieve effective and precise tooth movement. Whether Invisalign is suitable for your specific gummy smile will depend on the severity, the cause, and your orthodontist’s clinical assessment of whether aligner mechanics can deliver the needed movement reliably.
