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 Refuted in the verification pass from the clinic's own Happy Gas Dentist page: "you or your child will be awake throughout the procedure", and the page opens by saying the practice "cannot send you for general anaesthetic every time". Nitrous oxide only — conscious inhalation sedation, below the methodology's asleep-and-unaware bar. [s7]
Summary
General and cosmetic dental practice in the coastal western-Adelaide suburb of Semaphore. The clinic's named dentist, Dr Michael Frazis (practising since 2012), holds fellowships with the Australian Society of Implant Dentistry and the International Congress of Oral Implantologists and is fluent in Greek. The site publishes dedicated cost pages for Zoom whitening ($350–$1,000) and dental implants ($3,000–$6,000 per tooth), but declines to quote a figure for root canal treatment or Invisalign, so its price disclosure falls short of the methodology's three-service threshold for a published price list.

Score Breakdown
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 Dr Michael Frazis is named with a full bio on his own live profile page; the site's "Meet Our Team" hub link could not be resolved at the URL this agent guessed, so only this one dentist is individually confirmed even though the practice describes "our dentists" in the plural. [s2] | 3/3 |
| ✓ | Dentist specializations listed Dr Frazis: ASID Fellowship (implant dentistry, levels I–III), ICOI member, interest in cosmetic work and complex surgery. [s2] | 2/2 |
| ? | Real clinic photos | 0/2 |
| ✓ | Service list published Bridges, crowns, implants, Fast Braces, Invisalign, orthodontics, porcelain veneers, root canal treatment, tooth whitening. [s1] | 3/3 |
| ✓ | Clear contact details [s1] | 2/2 |
| ✓ | English website version [s1] | 2/2 |
| ✓ | Address and map published [s1] [sm] | 2/2 |
Price Transparency
2 / 15
Whether patients can estimate costs before visiting. Published price ranges count; exact prices are not required.
| ✗ | Prices or price ranges published Dedicated cost pages exist for four treatments, but only two (Zoom whitening, dental implants) actually quote a $ figure — the root-canal and Invisalign cost pages both explicitly defer to a free consultation instead of giving a number — short of the three-service threshold for a published price list. [s3] [s4] [s5] [s6] | 0/3 |
| ✗ | Cleaning price listed No standalone cleaning price; only a first-visit promotional bundle ("no gap or $199 without health fund, normally $272" comprehensive checkup + x-ray) is advertised, which is a time-limited new-patient offer, not a standing price. [s1] | 0/2 |
| ✗ | Filling price listed [s1] | 0/2 |
| ✗ | Crown price listed [s1] | 0/2 |
| ✓ | Implant price listed "A single tooth implant costs from $3000-$6000." [s6] | 2/2 |
| ✗ | Consultation price listed Only the promotional new-patient checkup bundle carries a figure; see cleaningPriceListed note. [s1] | 0/2 |
| ✗ | X-ray / imaging price listed X-rays are only priced as part of the promotional new-patient bundle, not as a standing standalone fee. [s1] | 0/2 |
Reputation & Reviews
19.5 / 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). Star histogram read from the same place page: 1*=5, 2*=1, 3*=5, 4*=30, 5*=706 — sums to 747, which reconciles with the header count, and its weighted mean reproduces the displayed rating. [gp] | 6/6 |
| ✓ | Google review volume Header count on the Google Maps place page, 2026-09-10. [gp] | 3/3 |
| ✓ | Review recency Newest customer review rendered on the place page is two months old. [gp] | 3/3 |
| ✓ | Clinic responds to reviews The owner has replied to reviews on Google: 1 of the 10 reviews read carry an owner reply; the latest reply is dated 2019-07-07 (to a review of 2019-07-07). [semaphore-dental-adelaide-r6rep] [gp] | 2/2 |
| ✓ | No recurring complaints Of 749 Google reviews, 6 are one- or two-star (0.8 %); the lowest-rated read (2019-2026) raise different matters (a root canal needing several visits, a booking problem, receptionists during a treatment plan), so no complaint recurs (read 2026-10-02). [semaphore-dental-adelaide-r6rep] | 2/2 |
| ✓ | No suspicious review patterns No five-star cluster and no repeated wording in the 10 Google reviews read (2019-07-07 to 2026-09-30); 9 are from accounts with other reviews of their own (read 2026-10-02). [semaphore-dental-adelaide-r6rep] | 2/2 |
| ✓ | Active Facebook presence Facebook page "Semaphore Dental" (1,195 followers) with posts up to 2026-04-23, found under the clinic's name; its About section gives the clinic's address and phone. [semaphore-dental-adelaide-presence] | 1/1 |
| ✗ | TripAdvisor presence No TripAdvisor listing found via its search for "Semaphore Dental Adelaide" and "Semaphore"; the clinic's site does not link to TripAdvisor (checked 2026-10-02 and 2026-10-05). [semaphore-dental-adelaide-tripadvisor] [semaphore-dental-adelaide-tripadvisor-2] | 0/0.5 |
| ✓ | Other review platforms Word of Mouth page for the practice at 62 Semaphore Road with 2 reviews (5.0), checked 2026-10-02. [semaphore-dental-adelaide-oop] | 0.5/0.5 |
Medical Infrastructure
13 / 15
The range of publicly documented equipment and services. This measures documented availability, not clinical quality.

| ? | CBCT (3D imaging) | 0/2 |
| ✓ | Implantology [s1] [s6] | 2/2 |
| ✓ | Orthodontics Fast Braces, Invisalign and a dedicated Orthodontics page. [s1] | 2/2 |

| ✓ | Pediatric dentistry "Kids Dentist" and "Happy Gas Dentist" pages target children. [s1] | 1.5/1.5 |
| ✓ | Emergency care The clinic's own Google Business Profile carries the owner-selected category "Emergency dental service" (place page read 2026-09-10). [gp] | 1.5/1.5 |
| ✓ | Works with international patients Dr Frazis "is fluent in Greek and enjoys helping patients who struggle to speak English." [s2] | 2/2 |
Communication & Service
6.5 / 10
How easy it is to contact the clinic, get answers, and book - especially for international patients.
