QUICK ANSWER

A gummy smile is when a lot of gum shows above your teeth when you smile. The right treatment depends on why it happens: excess or uneven gum can be corrected with gum contouring; teeth that look short may need reshaping or restoration; and in some cases the position of the teeth or jaw, or a very active lip, is the cause and calls for orthodontics or other options. Often the answer isn’t veneers at all — it’s addressing the gum line. A proper assessment identifies the cause so the least invasive fix can be used.

KEY TAKEAWAYS

• A gummy smile shows excess gum above the teeth when smiling.

• The right fix depends on the cause: gum, teeth, lip or jaw position.

• Gum contouring can reshape an uneven or excessive gum line.

• Often the solution is the gum line — not veneers on the teeth.

Many people who dislike their smile assume the answer is veneers — but sometimes the teeth are fine and it’s the gum line that’s the issue. A “gummy smile,” where a lot of gum shows when you smile, is a good example. Treating it well means understanding why it happens, because the right fix can be simple and conservative. Here’s an honest guide to gummy smile treatment and the options available.

What is a gummy smile?

A gummy smile is when an excessive amount of gum tissue is visible above the upper teeth when you smile, making the teeth look short even if they’re a normal size.

It’s a common and completely normal variation, and how much gum “too much” means is partly personal preference. Some people are happy with it; others feel self-conscious. The good news is that it’s very treatable once the cause is clear.

What causes a gummy smile?

A gummy smile can be caused by excess or uneven gum tissue, teeth that appear short, an overactive upper lip, or the position of the teeth and jaw — often a combination.

Excess or uneven gum tissue

Sometimes the gum simply covers more of the tooth than average, or sits unevenly, making teeth look short.

Short-looking teeth

Teeth worn down or naturally short can create the impression of excess gum even when the gum is normal.

An overactive lip

A lip that lifts higher than average when smiling can expose more gum.

Tooth or jaw position

In some cases the position of the teeth or the way the upper jaw developed contributes, which may point towards orthodontics.

How is a gummy smile treated?

Treatment depends on the cause: gum contouring reshapes an excessive or uneven gum line, tooth reshaping or restoration addresses short teeth, and orthodontics or lip-related options are used where position or the lip is the cause.

• Gum contouring (gingivectomy) — reshaping the gum line to reveal more of the tooth, for excess or uneven gum.
• Crown lengthening — adjusting gum and sometimes bone to lengthen the visible tooth.
• Tooth reshaping or restoration — where teeth are short or worn.
• Orthodontics — where tooth or jaw position is the underlying cause (see our guide to orthodontics vs veneers).

Is gummy smile treatment worth doing without veneers?

Often yes — when the teeth themselves are healthy and well-shaped, correcting the gum line alone can transform the smile without touching the teeth, which is the most conservative option.

This is exactly the kind of case where a conservative clinic saves you unnecessary treatment. If your teeth are fine, there’s no reason to prepare them for veneers just to change how much gum shows — addressing the gum line directly is simpler, cheaper and preserves your natural teeth.

Does gummy smile treatment hurt, and how long does it take?

Gum contouring is usually a quick, minor procedure done under local anaesthetic with a short recovery, while treatments involving bone or orthodontics take longer.

The exact experience depends on which treatment you need. Simple gum reshaping is typically straightforward with minimal downtime; crown lengthening or orthodontic approaches involve more time. Your dentist will explain what to expect for your specific case.
