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) — No general anaesthesia or deep sedation documented Only oral sedation and nitrous oxide ("happy gas") offered, both explicitly conscious; no IV/twilight/general anaesthesia mentioned. [tlc-dental-castlereagh-deepen-9]

Every criterion below is scored from public sources. ✓ verified yes · ✗ verified no / not found · ◐ partial · ? unverified (scores 0, not a negative finding).
Information Transparency
18 / 20
Whether basic facts about the clinic - its team, premises, services, and location - are publicly verifiable.
| ✓ | Has a working website [s1] | 4/4 |
| ✓ | Dentist names listed AHPRA register and topexperts.com.au independently corroborate. Google Business listing now stands alone as 'TLC Dental' rather than being framed only as Dr Hoffenberg's smiledocs.com.au sub-profile.

Price Transparency
0 / 15
Whether patients can estimate costs before visiting. Published price ranges count; exact prices are not required.
Reputation & Reviews
18.5 / 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) Directly verified via Google Maps 2026-08-26 - supersedes the prior directory-reported figure of 4.9 from 188 reviews. [tlc-dental-castlereagh-deepen] | 6/6 |
| ◐ | Google review volume Directly verified via Google Maps 2026-08-26 - supersedes the prior directory-reported figure of 188. [tlc-dental-castlereagh-deepen] | 2.5/3 |
| ✓ | Review recency Most recent review ~1 month old (as of 2026-08-26) [tlc-dental-castlereagh-deepen] | 3/3 |
| ✓ | Clinic responds to reviews The owner replies to reviews on Google: 9 of the 10 reviews read carry an owner reply, 5 of them to reviews from the last 12 months; the latest reply is dated 2026-09-14 (to a review of 2026-09-09). [tlc-dental-castlereagh-deepen-11] [tlc-dental-castlereagh-gbp-2026-09-26] | 2/2 |
| ✓ | No recurring complaints Only 1 of the 257 Google ratings is 1–2★ (0.4 %), and 1 of the five lowest-rated reviews read scores 3★ or below, too few to repeat one complaint three times (1★ 1 / 2★ 0 / 3★ 0 / 4★ 3 / 5★ 253). [tlc-dental-castlereagh-deepen-11] | 2/2 |
| ✓ | No suspicious review patterns No burst and no templated texts: the 10 reviews read (dated 2015-06-03 to 2026-09-30) fall on 9 different days, at most 4 five-star reviews fall within any 3 days (under 10 % of the 257 reviews), and no two open with the same wording. [tlc-dental-castlereagh-deepen-11] | 2/2 |
| ✓ | Active Facebook presence Facebook page "TLC Dental" (987 followers) with posts up to 2026-09-29, found under the clinic's name; its About section gives the clinic's Castlereagh Street address. [tlc-dental-castlereagh-presence] | 1/1 |
| ✗ | TripAdvisor presence No TripAdvisor listing found via its search for "TLC Dental Sydney" and "TLC Dental"; the clinic's site does not link to TripAdvisor (checked 2026-10-05). [tlc-dental-castlereagh-tripadvisor-3] [tlc-dental-castlereagh-tripadvisor-2] | 0/0.5 |
| ✗ | Other review platforms No review profile on WhatClinic, Word of Mouth, RateMDs or HealthEngine (checked 2026-10-02): the RateMDs page is an empty automatic listing and HealthEngine shows only the Google rating.
