Gap Teeth (Diastema) Correction in Seomyeon, Busan

Gap teeth (diastema) correction closes spaces between teeth, most often between the upper front teeth. At Seomyeon clinics, options include orthodontic closure with aligners or braces over a few months, tooth-coloured resin bonding or veneers in one or two visits, or a combination. The right choice depends on the gap's cause, size and your bite, and retainers are needed after orthodontic closure.

What is a diastema?

A diastema is a visible space between two teeth. Small gaps are common in children and often close as permanent teeth erupt. In adults, gaps may be caused by teeth that are small relative to the jaw, missing or peg-shaped lateral incisors, a thick lip frenum (the tissue attaching the lip to the gum), tongue thrusting, or gum disease causing teeth to drift and fan out.

Who is it for?

• Adults and teens who want gaps closed for appearance
• People whose gaps trap food or affect speech
• Patients with spacing from missing teeth who also need space redistributed for implants

If gaps are new or widening in adulthood, gum disease should be ruled out first, because closing spaces without treating the cause will not be stable.

What happens at the clinic

1. Assessment: the dentist or orthodontist checks tooth size, bite, frenum and gum health, often with X-rays.
2. Option discussion: orthodontic closure moves teeth together; bonding or veneers make teeth wider. Combining both can give balanced tooth proportions.
3. Orthodontic route: clear aligners or partial braces close the space, typically over several months.
4. Restorative route: composite resin is added and shaped, or veneers are made.
5. Retention: a thin fixed retainer behind the teeth or a removable retainer keeps the gap closed.

Recovery and aftercare

Orthodontic closure causes mild pressure for a few days with each adjustment. Bonding needs no recovery, though resin can stain and chip, needing occasional polishing or repair. Retainer wear is important because midline gaps are known for reopening.

Risks and side effects

Gaps can reopen without retention. Closing large gaps only with bonding can make teeth look too wide. If a frenum is the cause, the gap may not stay closed until it is addressed. Underlying gum disease must be controlled first.

Choosing a clinic for gap correction in Seomyeon

• Ask whether orthodontics, bonding, veneers or a combination gives the most natural proportions.
• Ask whether your frenum or tongue habit contributes to the gap.
• If gaps are new, ask for a gum health assessment before treatment.
• Ask what type of retainer is planned and for how long.
• Request a digital preview or mock-up if choosing bonding or veneers.

Short-stay option

Resin bonding can be completed in a single visit during a trip to Busan, while orthodontic closure needs months. Seomyeon's clinics are a quick subway ride from Busan Station.

Frequently asked questions

What is the fastest way to close a gap between teeth?

Composite bonding can close small gaps in a single visit. Orthodontic closure takes months but moves teeth without adding material, keeping natural tooth proportions.

Will a gap between my front teeth come back?

Midline gaps commonly reopen without retention. A thin bonded retainer behind the teeth is often recommended after orthodontic closure.

Do I need a frenectomy to close a gap?

Only if a thick or low frenum is preventing closure or causing relapse. Your dentist or orthodontist will assess this and may refer for a minor procedure.

Can clear aligners close gaps?

Yes. Aligners are well suited to closing many gaps, often within several months, as long as the bite allows.

Why are new gaps appearing between my teeth?

New spacing in adults can signal gum disease, tongue pressure or tooth loss elsewhere. See a dentist to identify the cause before closing the gaps.
