What Is a Cavity?

A cavity (also called dental decay) is damage to a tooth’s surface or inner structure caused by bacterial acid. If left untreated, it can progress into deeper layers of the tooth, leading to pain, infection, or even loss of the tooth. Clinics in Gangnam focus on early detection and efficient treatment using modern materials and technology.

Why Choose Gangnam, Seoul for Cavity Treatment

• Numerous dental clinics in Gangnam offer advanced diagnostics (digital X-rays, intra-oral scanning) and efficient, high-quality fillings.
• Many clinics cater to international and expat patients, with English-speaking staff, transparent pricing, and foreign-patient support.
• Competitive pricing compared to many Western countries, making cavity treatment more affordable without compromising quality.

Types of Filling Materials & Options

• Composite (Resin) Fillings: Tooth-coloured resin material blended to match your natural teeth. Good for visible areas and aesthetic repair.
• Ceramic / Inlay / Onlay: More durable, high-quality materials for larger cavities or replacement of old fillings. In Korea, inlays can cost from ~$300 to $600 USD per tooth.
• Amalgam or Glass Ionomer: Less common in premium aesthetic clinics, but sometimes used depending on location and budget.

Procedure: What to Expect

1. Consultation & X-Ray / Scan – The dentist identifies decay, checks the depth, and discusses options.
2. Numbing the Area – Local anaesthesia is applied if needed to ensure comfort.
3. Decay Removal – The dentist removes the decayed portion of the tooth and cleans the cavity.
4. Filling Placement – Resin or chosen material is placed, shaped, cured (hardened by light) and polished.
5. Bite Check & Final Adjustment – Ensuring the filling aligns well with your bite and feels comfortable.
6. After-care Advice – Guidance on how to look after your restoration and prevent future decay.
