Gummy Smile Treatment Options Explained

What counts as a gummy smile

Gum exposure of 3 mm or more above the top of the upper front teeth when smiling is usually perceived as gummy. 1–2 mm is well within the normal range and often considered youthful.

The four main causes

1. Short clinical crowns

Your teeth are there, but gum covers too much of them. Treatment: gum contouring or crown lengthening to expose more tooth surface (gum contouring explained).

2. Overactive upper lip

Your lip lifts too high when you smile. Treatment: botulinum toxin (anti-wrinkle) injections into the lip-elevator muscles — a quick injection whose effect typically lasts around 3–6 months.

3. Vertical maxillary excess

The upper jaw is positioned too low, so gum naturally shows. Treatment: orthognathic (jaw) surgery, carried out in a hospital setting and usually combined with orthodontic treatment. It is generally only considered when other features also warrant surgery.

4. Altered passive eruption

The gums didn't fully recede during tooth eruption. Treatment: crown lengthening with soft tissue and sometimes bone recontouring.

Diagnosis matters

The same "gummy" appearance can come from any of these four causes. Before treatment, the smile is usually photographed and videoed, upper-lip movement is measured and tooth proportions are assessed. Getting the diagnosis right determines which treatment actually works.

Treatment costs in Dubai

• Gum contouring (per arch): AED 2,500–4,500

Crown lengthening involving bone and lip injections are priced after an assessment, and jaw surgery is a hospital procedure outside routine dental fees. The pricing page lists current treatment ranges.

Combining approaches

A common plan: crown lengthening + veneers + repeat lip injections as needed. This tackles both the tooth-length issue and the lip hyperactivity. Gum contouring and porcelain veneers describe the dental parts of that plan.

What recovery looks like

Gum contouring

3–5 days of mild tenderness, a soft diet for 48 hours, and full healing at about 2 weeks.

Crown lengthening

5–10 days of soreness and stitches removed at about 1 week. The gum line keeps maturing for several months, so final veneers are often placed once it has settled.

Lip injections

Immediate return to normal; the effect builds over the first one to two weeks.

When to avoid lip injections as the sole fix

If gum exposure exceeds 5–6 mm and your teeth actually look short in proportion, lip injections alone will help only modestly. In those cases, crown lengthening (exposing more tooth) combined with injections gives a more balanced result. The laser options for reshaping soft tissue are covered in laser dentistry applications.

Common questions

Can you fix a gummy smile at home?

No. There is no at-home method that changes how much gum shows when you smile. The treatments that do, such as laser gum contouring to reshape the gum line, anti-wrinkle injections to relax an overactive upper lip, and crown lengthening for more complex cases, all need to be carried out by a dentist after assessing the cause. A gummy smile can come from the gums, the lip or the jaw, so the cause determines which treatment makes sense.

Practical decision guide

Cosmetic dentistry is strongest when the smile plan starts with healthy teeth and gums, not with a material choice. Before committing to a visible change, confirm the diagnosis, preview the result on your own face, and understand what tooth structure will or will not be removed.

Check this first

• Gum health, cavities, bite forces, grinding history, and old restorations.
• Whether whitening, bonding, alignment, veneers, or crowns is the least-invasive option that meets the goal.
• How the proposed shade and tooth shape will look in daylight, photos, and normal conversation.

When to book sooner

• The tooth is chipped, dark after trauma, sensitive, mobile, or changing colour quickly.
• You are being offered irreversible treatment without x-rays, gum screening, photos, or a trial smile.
• You grind at night and no nightguard or bite plan is included.

Topic-specific notes

• For cosmetic work, the most protective sequence is health check, photos, smile preview, trial or mock-up where appropriate, then final treatment. Irreversible tooth preparation should not be the first step in the conversation.

Questions to ask at the appointment

• Can I see a digital preview or trial smile before irreversible preparation?
• How much enamel will be removed, and is there a lower-prep alternative?
• What happens if the restoration chips, stains, or needs replacement later?

Dubai patient note

For Dubai cosmetic treatment, ask for a written plan that separates consultation, scans, mock-up, treatment, nightguard, warranty terms, and maintenance visits. If a clinician or facility is unfamiliar, verify licensing through DHA before starting.
