A gummy smile means a lot of gum shows when you smile. The cause decides the treatment: it can be an active upper lip, extra gum, short-looking teeth or the position of the jaw. Jaw botox is published at ₩90K–₩150K, but botox suits only some cases, so an examination comes first. Many people need only one approach, and some need a combination, which your dentist explains after seeing your smile.
What Causes a Gummy Smile
A gummy smile is usually described as showing a large band of gum above the upper teeth. Several different things can produce this, and they are treated differently.
Looking at a photo of you smiling, plus an examination of the teeth, gums and bone, helps your dentist work out which cause applies to you.
It helps to know that a gummy smile is a variation, not a disease. Some people are not bothered by it, and treatment is a personal choice. If you do want to change it, the first step is understanding which of the causes below is yours, because treating the wrong one gives little benefit.
Bring a smiling photo you feel is natural, and mention if the look has changed over time. A change after orthodontic treatment, gum swelling or medication can point to a different cause than a lifelong pattern.
- An upper lip that lifts higher than average when you smile.
- Gum that sits lower over the teeth, so the teeth look short.
- Upper front teeth that have moved down or forward.
- The position or growth of the upper jaw.
Treatment Options
The options range from a temporary, non-surgical approach to longer-lasting changes. The simplest suitable option is usually discussed first.
Botox for the lip muscles
A small amount of botulinum toxin can reduce how far the lip lifts. The effect is temporary and wears off, so it may need repeating. The published figure is for jaw botox; confirm the price for your own case.
Gum reshaping (crown lengthening)
Where gum covers too much of the tooth, a dentist can reshape the gum line. It is suitable only when the tooth and bone allow it.
Orthodontics
If front teeth have moved down or forward, moving them back into position may reduce the gum shown. Invisalign is published at ₩2.5M–₩7M.
Veneers or crowns
When teeth are short, longer-looking teeth may balance the smile. A laminate veneer is published at ₩600,000 per tooth, VAT included.
Gummy Smile Correction for Taepyeong, Moran, Sujin and Bundang Residents
The clinic is in Sujin-dong, Sujeong-gu, Seongnam, beside Taepyeong Station Exit 5. Residents of Moran, Sujin, Sinheung and Gachon, and those coming from Bundang, can reach us by rail without relying on a car.
English consultation is available, so you can describe what you notice and ask questions as you go. The clinic is open Mon–Wed 09:30–20:30, Thu 09:30–19:00, Fri 09:30–18:30 and Sat 09:30–13:00, with no lunch break; it is closed on Sundays and open on public holidays.
Some options, such as orthodontics or a veneer plan, involve several visits, while others, such as botox, are shorter. Use a map app to plan your route; we do not state travel times.
Matching Cause to Treatment
The table shows how causes usually line up with options. It is a general guide, and your dentist applies it to your own face and teeth.
| Likely cause | Option to discuss | Lasting? |
|---|---|---|
| Very active upper lip | Botox | Temporary; may need repeating |
| Extra gum over the teeth | Gum reshaping | Longer lasting; depends on the case |
| Teeth positioned low or forward | Orthodontics | Lasting with retainers |
| Short-looking teeth | Veneers or crowns | Long-lasting, may need replacement later |
| Jaw position | Specialist assessment | Depends on the approach |
Honest Limits
Not every gummy smile needs treatment, and not every treatment suits every cause. Botox cannot move teeth or remove gum. Gum reshaping cannot help if the main cause is the lip. A large skeletal cause may need an approach beyond what a general clinic offers, and your dentist should say so plainly.
Results depend on your case, and we do not promise a particular outcome. You will be told the likely benefits, the limits and the cost before you decide.
If you have a mix of causes, a combination may be suggested, but a combination is not always necessary. Ask your dentist which single step would make the biggest difference, and whether you can start with the least invasive one.
What to Expect at the First Visit
The first visit is about understanding the cause. You are not expected to decide anything on the day.
Smile assessment
Your dentist looks at how your lip, gums and teeth move together when you smile.
Examination
Teeth, gums and bite are checked, with X-rays if needed.
Options explained
You hear which option fits your cause, the simplest first, with pros and cons.
Cost
Published prices are a guide. Your final cost is quoted after examination.
Comparing Costs
Costs vary a great deal between options, from a small one-off fee to a full treatment plan. The table lists published figures where they exist.
| Option | Published price (KRW) | Notes |

| Jaw botox | ₩90,000–₩150,000 | Confirm for your own case |
| Gum reshaping | Quoted after examination | Depends on the area |

Gummy Smile Correction: frequently asked questions
Can botox fix a gummy smile?
It can help when an overactive upper lip is the main cause. It is temporary, and it does not help if the cause is gum or tooth position.
How much does botox for a gummy smile cost?
Jaw botox is published at ₩90K–₩150K. Confirm the price for your own case at consultation.
Can Invisalign correct a gummy smile?
It may help when front teeth have moved down or forward. Invisalign is published at ₩2.5M–₩7M, depending on the case.
Is the treatment permanent?
That depends on the option. Botox wears off, while gum reshaping and orthodontics are longer lasting. Your dentist will explain which applies.
Is gum reshaping suitable for everyone?
No. It works when extra gum covers the teeth and the bone allows it. If the lip is the main cause, reshaping will not help.
Will veneers help a gummy smile?
They can help when teeth look short, by making them look longer. A laminate veneer is published at ₩600,000 per tooth, VAT included.
Do I need treatment at all?
No. A gummy smile is a variation, and treatment is a personal choice. An examination shows what is possible if you want a change.
Do I have to book in advance?
Please contact the clinic first so a time can be arranged. English-language consultation is available. We are open Monday to Saturday (Saturday until 13:00), closed Sundays.
