General Anaesthesia & Deep Sedation
Whether the clinic documents treatment under general anaesthesia or deep / twilight sedation — "sleep dentistry", where the patient is asleep and unaware (does not feel, see, or hear the procedure). Ordinary conscious sedation, where the patient stays awake and responsive, does not count here. This is informational and does not affect the transparency score.
- ? General anaesthesia / deep sedation (sleep dentistry) — Not verified No sedation service described on site; only notes doctor's membership in Korean Society of Dental Anesthesia.

Score Breakdown
Every criterion below is scored from public sources. ✓ verified yes · ✗ verified no / not found · ◐ partial · ? unverified (scores 0, not a negative finding).

Price Transparency
Whether patients can estimate costs before visiting. Published price ranges count; exact prices are not required.
Reputation & Reviews
Public review signals. The Google rating is adjusted with a Bayesian prior (rating 4.0, weight 25) so a 5.0 from a handful of reviews does not outrank a 4.8 from hundreds.

| ✓ | Clinic responds to reviews The owner replies to reviews on Google: 1 of the 10 reviews read carry an owner reply, 1 of them to reviews from the last 12 months; the latest reply is dated 2026-09-15 (to a review of 2026-09-15).

| ? | No recurring complaints 1–2★ ratings are 7 of 84 (8.3 %), but the lowest-rated reviews read as mostly treatment-quality complaints (pain after treatment, damage found by another orthodontist after veneers, a rough cleaning), but three of the five come from accounts sharing one family name within four weeks, so one story may be counted three times. [gangnam-gentle-dental-deepen-2] | 0/2 |
| ? | No suspicious review patterns A 1★ review (2025-08-09) alleges that the positive reviews are fake, and three 1★ reviews from accounts with one family name fall within four weeks (2025-01-31 to 2025-02-28); the five-star reviews read show no burst, but the allegation and the cluster keep the pattern open.
