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.

Reputation & Reviews

12.5 / 20

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.

◐ Google rating (Bayesian-adjusted) Star histogram read live on 2026-09-06 from the place page: 61 five-star, 4 four-star, 1 three-star, 3 two-star, 7 one-star. The buckets sum to 76, matching the 76 in the place-page header exactly, and the weighted mean 4.434 reproduces the published 4.4. [gmpI5] 4/6
◐ Google review volume Read live on 2026-09-06 from the place-page header; the star histogram sums to the same figure. [gmpI5] 1.5/3
✓ Review recency The newest review visible is 1 month old, which proves the within-3-months bucket and no better. Sample: the 3 reviews Google Maps renders on the place page, in Google's relevance order; a newest-first list was not available. [gmpI5] 3/3
✓ Clinic responds to reviews The owner has replied to reviews on Google: 4 of the 9 reviews read carry an owner reply; the latest reply is dated 2025-05-07 (to a review of 2025-05-07). [koh-dental-surgery-jurong-east-deepen-18] [gmpI5] 2/2
? No recurring complaints 1–2★ ratings are 10 of 77 (13.0 %), but the lowest-rated reviews read as different matters (rude customer service, a 90-minute wait in 2016, a denture that did not fit, an appointment pushed back a month, one bare “No good”), so no theme is shared by three. [koh-dental-surgery-jurong-east-deepen-18] 0/2
✓ No suspicious review patterns The 61/4/1/3/7 shape populates every bucket, tapers plausibly and carries a substantial genuine negative tail; that is the opposite of a manipulation signature. The three visible reviewers hold 2, 2 and 20 reviews (the last a Local Guide with 41 photos), name three different dentists and post one, five and eleven months apart. Sample: the 3 reviews Google Maps renders on the place page, in Google's relevance order; a newest-first list was not available. [gmpI5] 2/2
✗ Active Facebook presence Corrected from true to false on 2026-09-07 after opening the page, which the earlier pass could not do. Koh Dental Surgery runs one Facebook page and it is the other branch's: it is named "Koh Dental Surgery Pte Ltd NeWest", writes itself as "Koh Dental Surgery Pte Ltd@NeWest", carries 566 followers and publishes 1 West Coast Drive, Newest Condo #01-03/04, Singapore 128020. The operator's own site links that page and no other. This card is the Jurong East premises at Blk 252 Jurong East St 24 #01-149, 600252 — a separate premises that the MOH register also lists separately — and it has no Facebook page of its own. The earlier true rested on the chain-level link from the operator's site; the same branch discipline this index applied to the Google listing and the MOH licence is applied here. [s1] [y1a] [y1b] 0/1
✗ TripAdvisor presence No TripAdvisor listing found; site does not link to TripAdvisor [koh-dental-surgery-jurong-east-deepen-12] [koh-dental-surgery-jurong-east-deepen-13] 0/0.5
✗ Other review platforms No clinic profile on WhatClinic, Dental Departures, Bookimed or Trustpilot (checked 2026-10-01).

Medical Infrastructure

11 / 15

The range of publicly documented equipment and services. This measures documented availability, not clinical quality.

✓ On-site X-ray X-rays taken at check-ups when due; an OPG X-ray is taken at the wisdom-tooth assessment. [s3] [s4] 2/2
? CBCT (3D imaging) 0/2
✓ Implantology Straumann and Osstem implant brands named. [s1] 2/2
✓ Orthodontics Braces, Invisalign, Zenyum. [s1] 2/2
✓ Oral surgery Wisdom-tooth extraction. [s1] 2/2
✓ Pediatric dentistry "Children are welcome at both clinics"; first visits kept short and unhurried. [s3] 1.5/1.5
✓ Emergency care "We keep time aside each day for patients who need to be seen quickly" — same-day urgent slots documented. [s3] 1.5/1.5
? Works with international patients 0/2

Communication & Service

8.5 / 10

How easy it is to contact the clinic, get answers, and book - especially for international patients.

✓ WhatsApp / LINE available [s1] 2/2
? Response speed 0/1.5
✓ English spoken [s1] 2.5/2.5
✓ Pre-visit consultation possible Services page invites patients to book a consultation before treatment, with cost/timeline explained at that visit [s3] 1.5/1.5
✓ Clear service explanations [s1] 1/1
✓ Convenient opening hours Jurong East branch open Saturdays (site: 9am-5pm; Google listing: 9-1, 2-5:30pm), satisfying the weekend-opening criterion [koh-dental-surgery-jurong-east-deepen-2] [koh-dental-surgery-jurong-east-deepen-10] 1.5/1.5

AI & Search Visibility

Licensing & Credentials

Whether the clinic publishes its operating licence and the dentists working there together with their professional licence numbers. A verified “not published” is recorded as a red flag; data we have not checked yet is shown as unverified and carries no penalty.

Clinic operating licence: 9400866(L) - MOH HCI code (Mode of Service Delivery: L, Permanent Premises), registered as KOH DENTAL SURGERY PTE LTD - JURONG EAST at 252 Jurong East St 24 #01-149, Singapore 600252 (HealthHub Healthcare Directory, the Ministry of Health's public institution register, read in a browser 2026-09-06) UEN 199003611D — KOH DENTAL SURGERY PTE LTD, Live Company, incorporated 26 Jul 1990, registered office 1 West Coast Drive #01-03/04, NEWEST, Singapore 128020 (sgpbusiness.com, an ACRA-sourced business register mirror, read 2026-09-07). (The register independently confirms the two-branch structure the verification pass warned about when it queued the g.page row: the practice's other premises is registered as KOH DENTAL SURGERY PTE LTD at 1 West Coast Drive #01-03/04 NEWEST, Singapore 128020, and only the Jurong East record carries this card's address and unit. No UEN is published on the record. sgpbusiness.com lists only one live Koh Dental Surgery entity, matching this card's MOH licensee name exactly; its ACRA registered office is the practice's other premises, at NEWEST, not this card's Jurong East premises — consistent with the MOH register's own finding that one Pte Ltd (this UEN) operates both branches under separate HCI codes.)

Change History

DateChange
2026-10-01Checked WhatClinic, Dental Departures, Bookimed and Trustpilot on 2026-10-01: no profile of the clinic on any of them, so presence on other review platforms is recorded as absent.
2026-09-29Checked TripAdvisor's own search and the clinic's website for a TripAdvisor profile: none found on either channel.
2026-09-29Corrected 2026-09-29: no recurring complaints now unverified: 1–2★ ratings are 10 of 76 and the low reviews themselves were not read.
2026-09-17Re-read on 2026-09-17: the clinic’s website (services, CHAS/Medisave, contact, team and history pages) and its Google listing photos. Recorded: no price figures for any listed treatment anywhere on the site; genuine business-uploaded photos of the Jurong East premises and team; a booking-a-consultation offer; Saturday opening; site-wide structured data; one consolidated services page rather than dedicated pages per treatment. Still unverified: TripAdvisor and other review-platform presence, whether the clinic documents work with international patients, and whether it offers CBCT imaging.
2026-09-07Close-out, 2026-09-07: UEN found via ACRA copy sgpbusiness.com: 199003611D, registered office is the company's other branch (NEWEST).
2026-09-07Close-out, 2026-09-07: the two Jurong East Facebook pages were opened. Sincere Dental's is confirmed against this card's address; Koh Dental Surgery's turns out to be the operator's other branch, so this card's onFacebook is corrected to a disclosed negative.
2026-09-06Checked by hand in a browser: the Google Maps branch place page was opened in a real browser and read for the full Google reputation block and the pin, and the branch's MOH operating licence was read from the HealthHub Healthcare Directory.
2026-09-04Adversarial verification pass 2026-09-04: the clinic's own /our-dentists, /services and /chas-medisave-subsidies pages were opened for the first time; dentist names, specializations, X-ray, paediatric and same-day emergency care all corrected from "not published" to published. SDC entry D25266B re-checked live.
