Change History
| Date | Change |
|---|---|
| 2026-09-18 | Re-read on 2026-09-18 together with a neighbouring clinic's re-read: the clinic's English and Thai sites, the Google listing and reviews of the Ratchadaphisek head office, the Ministry of Public Health register of private healthcare facilities and the Dental Council of Thailand register. The head office holds operating licence 10103002557 (valid until 2033), and the fifteen dentists named on this page hold a licence in the Dental Council register. The fee list gives standing prices for check-ups (free), X-rays, cleaning, fillings, crowns and root canal treatment; implant fees are shown only as promotions. The site also describes 3D CT scanning, children's dentistry and same-day appointments by phone. Four Google reviewers state that the clinic offered a discount or a promotional price in return for a review, several low-rated reviews describe long waits or an appointment not kept, and the clinic does not reply to Google reviews. Google: 5.0 from 2,834 reviews. |
| 2026-08-26 | Correction 2026-08-26: the clinic licence had been shown as not published after two Thai spellings of the name returned no match; under the Thai-script spelling Samai Siknechoe (Smile Signature) the Ministry of Public Health register lists licence 10103002557 at the clinic's Ratchadaphisek address, valid to 31 December 2033. |
| 2026-08-25 | Re-verification 2026-08-25: confirmed website live (smilesignature.com) and Ratchadapisek head-office address unchanged; recorded updated Google rating 5.0 with 2,827 reviews (up from 4.8/683). Google lists the business as 'Smile Signature Ratchada Dental'. |
| 2026-08-23 | Recorded sedation / general anaesthesia availability (informational): documented as available. Partners with BIDH Dental Hospital for 'total sleep dentistry' (GA/IV sedation) for anxious patients. |
| 2026-08-14 | Added Licensing & Credentials (methodology v1.1): clinic licence and dentists/their licence numbers. (originally recorded 2026-07-08) |
| 2026-08-14 | Imported from the city-tier dataset (data originally collected 2026-07-03). |
