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.

Summary
Family-owned general practice in Parkside, just south of the Adelaide CBD, founded by Dr Polly Hing in 2015. Three dentists are named with individual bios (Hing, Dr Souchin Sam, and in-house oral surgery registrar Dr Benjamin Dang), and staff are stated to speak Khmer, Spanish, Serbian, Farsi and English. The clinic accepts public SADS/GDS/EDS/CDBS/Medicare schemes and advertises a discounted new-patient exam package, but that is a time-limited offer rather than a standing price list.

Price Transparency
0 / 15
Whether patients can estimate costs before visiting. Published price ranges count; exact prices are not required.
| ✗ | Prices or price ranges published The only figure published is a time-limited "New Patient Offer" ($380, save $114 off a regular $494 comprehensive exam+x-rays+clean package) — a promotional price, not a standing price list for three or more services. [s1] | 0/3 |

Reputation & Reviews
17.5 / 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) Read live from the clinic's Google Maps place page 2026-09-10 (automated two-step place read, name/address/phone cross-checked against the clinic's own site). Review count not carried by the response served for this place — queued for a manual browser check. [gp] | 6/6 |
| ◐ | Google review volume as of 2026-09-25; previously 80 [optimal-dental-care-parkside-adelaide-gbp-2026-09-25] | 1.5/3 |
| ✓ | Review recency Newest first-person star review readable on the Google Maps place page on 2026-09-10 is dated "a month ago" (3 reviews readable). Google Maps' sort-by-Newest control does not open in this browser session, so the list was read in its default relevance order; Google Business Posts on the same panel were excluded because they carry no star rating. [gp] | 3/3 |
| ✓ | Clinic responds to reviews The owner replies to reviews on Google: 10 of the 10 reviews read carry an owner reply, 9 of them to reviews from the last 12 months; the latest reply is dated 2026-10-01 (to a review of 2026-09-28). [optimal-dental-care-parkside-adelaide-r6rep] [gp] [gm-replies] | 2/2 |
| ✓ | No recurring complaints Of 91 Google reviews, 2 are one- or two-star (2.2 %); the lowest-rated read (2023-2025) raise different matters (a dispute over insurance claims and staff conduct), so no complaint recurs (read 2026-10-02). [optimal-dental-care-parkside-adelaide-r6rep] | 2/2 |
| ✓ | No suspicious review patterns No five-star cluster and no repeated wording in the 10 Google reviews read (2023-03-25 to 2026-09-28); 9 are from accounts with other reviews of their own (read 2026-10-02). [optimal-dental-care-parkside-adelaide-r6rep] | 2/2 |

| ✗ | TripAdvisor presence No TripAdvisor listing found via its search for "Optimal Dental Care Adelaide" and "Optimal"; the clinic's site does not link to TripAdvisor (checked 2026-10-02 and 2026-10-05).
