Black triangles—small gaps between the teeth near the gumline—are a common cosmetic concern. They can occur due to gum recession, bone loss, tight contacts between teeth, or the natural shape of the teeth. Many patients in Korea seek treatment not only for cosmetic reasons, but also to improve oral hygiene and prevent food impaction.



What Are Black Triangles?

Black triangles are triangular dark spaces that appear between adjacent teeth when the gum tissue does not completely fill the interdental space. They can make the smile look aged or uneven and may trap food particles, which can contribute to plaque buildup.

Treatment Options Available in Korea

There are several ways to address black triangles, depending on their size, cause, and the patient’s overall dental condition. Common treatment options in Korea include:

• Composite Bonding: Tooth-colored resin is added to fill the gap and reshape the teeth.
• Porcelain Veneers: Thin ceramic shells are bonded to the front of the teeth for a more permanent and aesthetic solution.
• Orthodontic Treatment: Braces or clear aligners can adjust tooth position to improve contacts and reduce black triangles.
• Gingival Recontouring: Minor gum surgery to reshape the gumline for a more uniform appearance.

Each method varies in complexity, longevity, and cost.

Average Cost of Fixing Black Triangles in Korea

The cost to fix black triangles in Korea depends on the treatment chosen:

• Composite Bonding: Approximately ₩100,000 to ₩300,000 per tooth, depending on the amount of material and complexity of shaping.
• Porcelain Veneers: Typically ranges from ₩600,000 to ₩1,200,000 per tooth, depending on veneer type and clinic.
• Orthodontic Treatment: Clear aligner or braces treatment can range from several million to over ten million Korean won, based on treatment duration and system used.
• Gingival Recontouring: Usually around ₩50,000 to ₩300,000 per site, depending on whether laser or surgical techniques are used.

Final costs vary by clinic location, dentist expertise, and whether additional procedures are needed.

Factors That Influence Pricing

Several factors affect the total cost of black triangle correction:

• Number of Teeth Treated: More teeth require more materials or longer procedures.
• Method Chosen: Bonding is generally less expensive, while veneers and orthodontics cost more.
• Dentist Skill & Technology: Specialist expertise and digital planning tools may increase pricing.
• Clinic Location: Clinics in central Seoul or premium districts may charge higher fees.

Insurance Coverage in Korea

Most black triangle treatments are considered cosmetic and are not covered by Korean National Health Insurance. Orthodontic treatments may have limited coverage under specific conditions, but usually patients pay out of pocket. Composite bonding and veneers are typically not reimbursed.

Longevity of Results

The durability of results varies by treatment:

• Composite Bonding: Lasts several years with good oral hygiene, but may need periodic maintenance or touch-ups.
• Veneers: Can last 10 years or more with proper care.
• Orthodontic Treatment: Results are long-lasting when retention protocols are followed.
• Gingival Recontouring: Soft tissue results are permanent, though gum changes may occur over time.

A dentist can provide personalized guidance on which option best fits your needs.

Costs depend on the method chosen, number of teeth involved, and the clinic selected. Consulting with an experienced cosmetic dentist will help you determine the best approach for both aesthetics and oral health.
