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

It is the one clinic in this set that publishes a complete standing price list in both Chinese and English, stated to follow the schedule announced by the Taichung City dental association, and it operates entirely on a private-pay basis with no National Health Insurance contract.

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
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 The medical-team page names Chang Wen-Hsin alongside Hung Chi-Chih, Lin Chun-Pei and Hsu Ken-Shih. The MOHW institution record counts 1 dentist registered at these premises (checked 2026-09-04); the register never publishes their names, so the published roster and the registration count cannot be reconciled from any official source. [s2] | 3/3 |
| ✓ | Dentist specializations listed Each dentist carries hospital appointments and society certifications, covering endodontics, orthodontics and oral surgery. [s2] | 2/2 |
| ✓ | Real clinic photos A clinic-space page showing the clinic's own premises. [s5] | 2/2 |
| ✓ | Service list published [s1] [s3] | 3/3 |
| ✓ | Clear contact details The site publishes a toll-free appointment line (0800-008-817) while the MOHW register carries the landline 04-23200250; the address matches exactly. [s1] [reg1] | 2/2 |
| ✓ | English website version A full English page covering the team, services and the complete price list. [s1] | 2/2 |
| ✓ | Address and map published [s1] [s4] | 2/2 |
Price Transparency
Whether patients can estimate costs before visiting. Published price ranges count; exact prices are not required.
| ✓ | Prices or price ranges published A standing two-part price table — first-visit charges and treatment charges — covering more than a dozen procedures with ranges, not a time-limited promotion. The clinic states the schedule follows the criteria announced by the Taichung City dental institution. [s1] | 3/3 |
| ✓ | Cleaning price listed Dental cleaning NT$1,200-3,000. [s1] | 2/2 |
| ✓ | Filling price listed Resin restoration for cavities NT$1,000-2,000; ceramic onlay NT$12,000-14,000. [s1] | 2/2 |
| ✓ | Crown price listed All-ceramic crowns NT$25,000-30,000; zirconia NT$30,000-35,000. [s1] | 2/2 |
| ✓ | Implant price listed Dental implant including crown NT$80,000-100,000; bone graft NT$20,000-60,000. [s1] | 2/2 |
| ✓ | Consultation price listed Registration fee NT$150 per visit; dental check-up and diagnosis NT$350. The clinic separately offers a free consultation for smile design and microscopic endodontics. [s1] | 2/2 |
| ✓ | X-ray / imaging price listed X-ray photograph NT$1,000 (one-off); 3D computed tomography NT$5,000 per region. [s1] | 2/2 |
Reputation & Reviews
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: 73 five-star, 1 four-star, 1 three-star, 0 two-star, 8 one-star. The buckets sum to 83, matching the 83 in the place-page header exactly, and the weighted mean 4.578 reproduces the published 4.6. [gmp1] | 4/6 |
| ◐ | Google review volume Read live on 2026-09-06 from the place-page header; the star histogram sums to the same figure. [gmp1] | 1.5/3 |
| ◐ | Review recency The newest review visible is 7 months old, which proves the within-a-year bucket and no better. Sample: the three reviews Google Maps renders on the place page in its own relevance order; a newest-first list was not available. [gmp1] | 1.5/3 |
| ✓ | Clinic responds to reviews The owner replied under visible reviews. Sample: the three reviews Google Maps renders on the place page in its own relevance order; a newest-first list was not available. [gmp1] | 2/2 |
| ✓ | No recurring complaints None of the three reviews Google renders is critical; all three are five-star, two of them naming the treating dentist. The histogram carries eight one-star ratings out of 83 (9.6 per cent) that the visible sample cannot reach, so this reading rests on the sample and the size of the unread tail is stated here. Sample: the three reviews Google Maps renders on the place page in its own relevance order; a newest-first list was not available. [gmp1] | 2/2 |
| ✓ | No suspicious review patterns The 73/1/1/0/8 shape carries a genuine negative tail rather than a clean wall, and the visible reviewers hold 90, 2 and 34 reviews. Sample: the three reviews Google Maps renders on the place page in its own relevance order; a newest-first list was not available. [gmp1] | 2/2 |
| ✓ | Active Facebook presence Facebook page of the clinic (2,758 followers) with 29 reviews (100% recommend); its About section gives the clinic's Dadun Road address, phone and website. [georgemicro-dental-taichung-presence-5] | 1/1 |
| ✗ | TripAdvisor presence No TripAdvisor listing found via its search for "Georgemicro Dental Clinic Taichung" and "Georgemicro Dental"; the clinic's site does not link to TripAdvisor (checked 2026-10-05). [georgemicro-dental-taichung-tripadvisor] [georgemicro-dental-taichung-tripadvisor-2] | 0/0.5 |
| ✗ | Other review platforms No review profile found (checked 2026-10-02): no reviewed or clinic-kept page on Dent&Co, Taiwan's dental review and booking site; WhatClinic and Bookimed do not cover Taiwan; no Trustpilot page. [georgemicro-dental-taichung-presence] [georgemicro-dental-taichung-presence-2] [georgemicro-dental-taichung-presence-3] [georgemicro-dental-taichung-presence-4] | 0/0.5 |
Medical Infrastructure
The range of publicly documented equipment and services. This measures documented availability, not clinical quality.
| ✓ | On-site X-ray Radiography is itemised in the published price list and documented on the equipment page. [s1] [s6] | 2/2 |
| ✓ | CBCT (3D imaging) 3D computed tomography is itemised in the published price list at NT$5,000 per region. [s1] [s6] | 2/2 |
| ✓ | Implantology [s3] | 2/2 |
| ✓ | Orthodontics Traditional orthodontics and Invisalign, both with published price ranges. [s1] | 2/2 |
| ✓ | Oral surgery Wisdom tooth extraction and bone grafting are itemised in the price list; the clinic also runs a referral channel for oral surgery. [s1] | 2/2 |
| ✗ | Pediatric dentistry Children's dentistry appears neither in the published service list nor in the price schedule. [s1] [s3] | 0/1.5 |
| ✗ | Emergency care The clinic works by appointment and documents no emergency or same-day service. [s1] [s3] | 0/1.5 |
| ✓ | Works with international patients The clinic publishes a full English page including its price list and states that all its dentists communicate in English. [s1] | 2/2 |
Communication & Service
How easy it is to contact the clinic, get answers, and book - especially for international patients.
| ✗ | WhatsApp / LINE available No LINE or WhatsApp channel is published; contact is by the toll-free line or the online reservation form. [s1] | 0/2 |
| ? | Response speed | 0/1.5 |
| ✓ | English spoken The clinic states that all of its dentists have English communication skills. [s1] | 2.5/2.5 |
| ✓ | Pre-visit consultation possible A free consultation is offered and an online reservation form promises contact within 24 hours. [s1] [s7] | 1.5/1.5 |
| ✓ | Clear service explanations [s3] | 1/1 |
| ✓ | Convenient opening hours Read in a browser on 2026-09-06. The published grid runs three sessions - 09:00-12:00, 14:00-17:00 and 18:00-21:00 - with Saturday and Sunday marked closed in all three rows, so there are no weekend clinics; the evening session runs to 21:00 on Tuesday, Wednesday, Thursday and Friday. Evening availability four nights a week is what carries the value, on the same reading applied to cheng-kuang-dental-tainan and shangding-dental-kaohsiung, which also publish evenings and no weekend. A correction to the open questions worth recording: the timetable is NOT an image - it is an ordinary HTML table on the page today, and the schedule names the dentists (Chang Wen-Hsin, Hsu Ken-Pin, Hung Hsu-Chih, Chen Yun-Ting, Lin Chun-Lu) session by session. [br1] | 1.5/1.5 |
AI & Search Visibility
Whether the clinic is discoverable when patients search - including via AI assistants. Checked with fixed queries: "best dentist Taiwan", "English speaking dentist Taiwan", "dental implants Taiwan", "emergency dentist Taiwan", "Taiwan dental clinic for expats".

| ✓ | Structured data on website A schema.org JSON-LD block is present in the page source (WebPage, WebSite, SearchAction, Article, Person, ImageObject), re-read 2026-09-04. [s1] | 1.5/1.5 |

| ✓ | Dedicated service pages Separate pages for microscopic endodontics, implants, digital smile design and the smile-design clinic process. [s3] | 1.5/1.5 |
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: Institution code 3703280212 — Georgemicro Dental Clinic, private dental clinic, operating status: operating, 1F and mezzanine, No. 817, Dadun Road, Nantun District, Taichung, phone 04-23200250; NHI-contract flag: no. MOHW medical institution search, checked 2026-09-04. (The clinic is absent from the National Health Insurance contracted-clinic file refreshed 2026-09-04, which matches the MOHW flag and the clinic's own statement that it is entirely self-pay; roughly 330 licensed Taiwanese dental clinics operate without an NHI contract, so this is not evidence of any licensing problem. The MOHW staffing record counts one registered dentist at these premises against the four the clinic names — consistent with visiting hospital specialists whose practice registration sits elsewhere, since the register never links a dentist to a clinic.)
