1) How It Works & Materials
1-1. Principle of In-office Whitening
A peroxide-based in-office gel acts on internal pigments to brighten teeth from the inside — without shaving enamel. Unlike abrasive polishing, it won’t scratch the tooth surface.

1-2. Premium In-office Gel
We use a premium gel optimized for the balance of low sensitivity and quick results, paired with controlled LED activation. Concentration and timing are managed under clinic protocols (details during consultation).
Why we chose this gel & our protocol
1-3. Home Whitening (Maintenance)
Our at-home whitening kit costs 400,000 KRW. Ask the hospital about its contents and instructions for use.

3) Procedure Flow (~90 minutes = 3 sessions)

4) Expected Results & Limits
We typically aim for 3–4 shades of improvement (varies). Yellowish teeth respond well; grayish or non-vital teeth may respond less. In those cases, ceramic veneers/crowns can improve both color and shape.
5) Safety & the “3-Session” Concept (Aftercare)
- 3 sessions in one visit: controlled LED activation targeting a natural finish with individualized timing.
- Gingival protection & sensitivity care are included for safety.
- For 24 hours post-treatment, avoid dark food/drinks & smoking. For ~2 hours post, avoid very hot/cold drinks and carbonated beverages for stability.
