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 Site blocks automated access (HTTP 403 / bot-challenge); no accessible third-party source found describing sedation depth.

Change History

DateChange
2026-10-05Reputation check 2026-10-02 on the clinic's Google listing (10 reviews read): suspicious review patterns no.
2026-10-01Other review platforms re-checked on 2026-10-01: no clinic profile on WhatClinic, Dental Departures or Trustpilot, so onOtherPlatforms is now false; the datum previously rested on the clinic's own site.
2026-09-25Re-read on 2026-09-25: the clinic's pricing, our-dentist, gallery, treatments and FAQ pages, plus its Google listing. Recorded: a named dentist with credentials; genuine team and case photos; cleaning, filling, crown, consultation and X-ray prices; documented emergency care; a free written quote on request before treatment; weekend opening hours; Dentist structured data; no TripAdvisor presence; recent reviews describe unclear billing on a couple of occasions.
2026-08-25License verification 2026-08-25: clinic website and Facebook page both blocked automated access (HTTP 403); no Thai name, licence number, or dentist names could be retrieved to check against the Dept. of Health Service Support or Dental Council registries.
