Ordinary conscious sedation, where the patient stays awake and responsive, does not count here. This is informational and does not affect the transparency score.

| 2026-08-25 | License 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. |
| 2026-08-25 | Re-verification 2026-08-25: confirmed via Google Business Profile that the clinic is open with address and phone unchanged and the listed website domain (dentalexcellencebylerts.com) matches; direct fetch of the site itself returned HTTP 403 / a bot-challenge in both WebFetch and a real browser, so site content and sedation info could not be independently verified today; captured first Google rating 4.9 (313 reviews) and coordinates. |
