A gummy smile occurs when an excessive amount of gum tissue is visible while smiling and can be an aesthetic concern for many people. This condition may affect self-confidence and cause individuals to avoid smiling. Treatment for a gummy smile aims to create a more balanced and aesthetic gum-to-tooth appearance. Below you will find what a gummy smile is, its causes and the available treatment options.
A gummy smile is defined as more than 2 millimetres of visible upper gum tissue when smiling. It can make the gums appear overly large and the teeth look shorter than they are. While usually considered an aesthetic issue, in some cases it can also affect gum health.
Common causes include:
Gingival overgrowth: Excess or swollen gum tissue making the gums more prominent.
Tooth position/size: Short or small teeth that make the gums more visible.
Jaw anatomy: Excessive vertical growth or abnormal position of the upper jaw.
Muscle activity: Overactivity of the muscles that elevate the upper lip.
Genetic factors: A hereditary tendency toward increased gum display.
Treatment depends on the underlying cause and severity. Common approaches include:
Gingival contouring (gingivectomy): Surgical removal of excess gum tissue to create a more aesthetic gum line.
Orthodontic treatment: Braces or aligners to correct tooth and jaw position.
Botulinum toxin (Botox) injections: Used when excessive upper-lip elevation is due to hyperactive muscles; injections reduce muscle activity and decrease gum display.
Lip-repositioning surgery: A surgical procedure that alters the position of the upper lip to reduce gum exposure.
Crown lengthening (tooth lengthening): Reshaping gum and sometimes bone around a tooth to expose more tooth structure and make teeth appear longer.
Improved aesthetics: A more balanced appearance between gums and teeth.
Increased self-confidence: A more pleasing smile can boost self-esteem and social comfort.
Better gum health: Procedures that correct excess gum tissue can improve hygiene and gum health.
Long-term solutions: Orthodontic and surgical options can provide permanent improvement.
To support healing and maintain results after gummy smile treatment:
Maintain good oral hygiene: brush and floss regularly and keep gums healthy.
Attend regular follow-up appointments so your dentist can monitor healing and outcomes.
Follow a healthy lifestyle and avoid tobacco to support gum health.
A gummy smile can be effectively managed with appropriate treatments. If you are unhappy with your smile or notice excessive gum display, consult a dentist to discuss suitable treatment options.
