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) — General anaesthesia / deep sedation documented The group publishes that treatment "under laughing gas or general anaesthetic" is possible thanks to its own team of anaesthetists. [s1]
Summary
Cornavin branch of the six-clinic CHD group, at Rue de Lausanne 65 — the address MedReg records as the authorised practice address "Clinique d'Hygiène Dentaire de Genève" for one of its managing dentists. The branch publishes its own roster of dentists and orthodontists with the languages each speaks, and the group publishes a full public price list with instalment terms. Its Google Business listing is titled "Dental Hygiene Clinic Geneva"; the card keeps the name the clinic uses for itself.

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
20 / 20
Whether basic facts about the clinic - its team, premises, services, and location - are publicly verifiable.
| ✓ | Has a working website Read live 2026-09-07: HTTP 200 with real clinic content (branch roster, treatment tree, pricing, FAQ), not a placeholder. [s1] | 4/4 |
| ✓ | Dentist names listed The Cornavin branch page names its own team: Dr Abra Hussein and Dresse Valentina Pagliara (heads of clinic), Dr Alessandro Guau, Dr Alireza Alipour Therany, Dresse Nina Jeanrenaud, Dresse Oumnia Bey and Dr Adrien Tellier (dentists), Dr Christian Schütz, Dr Valentin Friang, Dr Gauthier Bodart and Dresse Marion Pierrat (orthodontists), and Dresse Shainara Mascaro, Dr Robin Thomas and Dr Sofian Ameur (managing partners). [s1] | 3/3 |
| ✓ | Dentist specializations listed Each name on the branch roster carries a role (head of clinic, dentist, orthodontist, managing partner) and the languages that practitioner speaks. [s1] | 2/2 |
| ✓ | Real clinic photos The site serves photographs hosted on its own domain and named per branch ("chd-geneve-cornavin-3.jpg", "chd-geneve-eaux-vives-1.jpg"), i.e. genuine premises photography rather than only stock imagery. [s1] | 2/2 |
| ✓ | Service list published The group publishes a concrete treatment list with a page per item across hygiene and prevention, general dentistry, cosmetic dentistry, oral surgery, implantology, orthodontics and children's care. [s1] [s2] | 3/3 |
| ✓ | Clear contact details The branch publishes its own direct line 022 512 66 12, a WhatsApp route and an online booking link keyed to the Cornavin clinic; the number matches the Google place record. [s1] [m1] [m2] | 2/2 |
| ✓ | English website version Complete EN/FR site; the English tree carries the branch, pricing, treatment and team pages. [s1] [s2] | 2/2 |
| ✓ | Address and map published The branch page publishes the Rue de Lausanne 65 address with access details; it matches the Google place record and the practice address MedReg holds under the clinic's own name. [s1] | 2/2 |
Price Transparency
15 / 15
Whether patients can estimate costs before visiting. Published price ranges count; exact prices are not required.
| ✓ | Prices or price ranges published Permanent public price list covering hygiene, dentistry, orthodontics, aesthetics and surgery, with instalment terms (24 interest-free monthly payments) and a written estimate promised before treatment; these are standing prices, not a time-limited promotion. [s2] | 3/3 |
| ✓ | Cleaning price listed "Teeth cleaning + Polishing + Inspection + 2 X-rays 140.-" and, with a dentist's check-up, "190.-"; fast polishing 20 min 42.-. [s2] | 2/2 |
| ✓ | Filling price listed "Treatment of cavities from 200.- to 350.-". [s2] | 2/2 |
| ✓ | Crown price listed "Dental crown — On estimate after assessment ~1200.-". [s2] | 2/2 |
| ✓ | Implant price listed "Dental implants — Implant + crown ~3100.-" and, under replacement of missing teeth, implant from 2700.-. [s2] | 2/2 |
| ✓ | Consultation price listed "Check-up — Dental check-up with 2 x-rays 95.-" (50.- inside the Clean package); first orthodontic consultation 95.-. [s2] | 2/2 |
| ✓ | X-ray / imaging price listed Radiography is priced inside published packages ("Dental check-up with 2 x-rays 95.-", "Teeth cleaning + Polishing + Inspection + 2 X-rays 140.-"); read as a published price under the methodology's convention that a stated package price covering the x-ray counts, with the packaging disclosed here. [s2] | 2/2 |
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) Re-read live on the place page in a browser on 2026-09-08 and unchanged at 4.9. The star histogram's weighted mean, 4.858, reproduces the published figure. [gmp1] [gmpb] | 6/6 |
| ✓ | Google review volume Headline count for this branch read on the place page in a browser on 2026-09-08. The histogram is labelled in thousands and sums to the same figure: 1,226 five-star, 29 four-star, 4 three-star, 5 two-star and 33 one-star = 1,297. This is deliberately not the 4.9 out of 3,576 the group publishes in its own schema.org AggregateRating: that figure is group-wide and about two and three-quarter times this branch's base, although the 4.9 average matches. [gmpb] | 3/3 |
| ✓ | Review recency Browser 2026-09-08, 8 visible reviews, sort: Google's own "Most relevant" order. Two of the eight are three months old; the rest run 7 months to 6 years. [gmpb] | 3/3 |
| ✓ | Clinic responds to reviews Browser 2026-09-08, 8 visible reviews, sort "Most relevant": the owner has replied to seven of the eight. [gmpb] | 2/2 |
| ✓ | No recurring complaints Browser 2026-09-08, 8 visible reviews, sort "Most relevant": no review below five stars surfaced and no repeated theme is readable. One-star and two-star ratings together are 38 of 1,297, or 2.9 per cent of the base. [gmpb] | 2/2 |
| ✓ | No suspicious review patterns Browser 2026-09-08: histogram 1,226/29/4/5/33 with a mean of 4.858 against a published 4.9; a twenty-nine-strong four-star tail and thirty-three one-star ratings sit under the average, dates run from three months to six years and the accounts name different clinicians and hygienists. No manipulation signature. [gmpb] | 2/2 |
| ✓ | Active Facebook presence The group links its own Facebook page facebook.com/cliniquehygienedentaire and Instagram account from its site. [s1] | 1/1 |
| ✗ | TripAdvisor presence No TripAdvisor listing found via its search for the clinic's name and a short form of it; the clinic's site does not link to TripAdvisor (checked 2026-10-05). [chd-cornavin-geneva-tripadvisor] [chd-cornavin-geneva-tripadvisor-2] | 0/0.5 |
| ✓ | Other review platforms local.ch, the Swiss directory with its own user ratings, has the clinic's entry at its address: 3.7 of 5 from 7 ratings, 2 with written reviews (checked 2026-10-02). [chd-cornavin-geneva-platforms] | 0.5/0.5 |
Medical Infrastructure
13 / 15
The range of publicly documented equipment and services. This measures documented availability, not clinical quality.
| ✓ | On-site X-ray The published price list bills two x-rays inside its standard hygiene and check-up packages, i.e. radiography is performed on site. [s2] | 2/2 |
| ? | CBCT (3D imaging) No cone-beam/3D imaging statement was found on the pages read; not asserted either way. | 0/2 |
| ✓ | Implantology Dedicated implant pages including All-on-4, All-on-6 and All-on-8, with published implant prices. [s1] [s2] | 2/2 |
| ✓ | Orthodontics Dedicated orthodontics and Invisalign pages, four named orthodontists on the branch roster and a full published aligner and braces tariff. [s1] [s2] | 2/2 |
| ✓ | Oral surgery Dedicated pages for wisdom-tooth extraction and gum grafting under a "Dental Surgery" section with published prices. [s1] [s2] | 2/2 |
| ✓ | Pediatric dentistry A dedicated children's section (CHD Kids) with children's check-ups, cavity treatment, fissure sealants, children's orthodontics and emergencies, plus a reduced under-13 hygiene price. [s1] [s2] | 1.5/1.5 |
| ✓ | Emergency care Dedicated "Dental emergencies Geneva" page and a published emergency price ("According to treatment ~150.-"); the branch markets same-day care. [s1] [s2] | 1.5/1.5 |
| ✓ | Works with international patients The branch page publishes the languages each named dentist, orthodontist, hygienist and assistant speaks — French, English, Italian, Spanish, Portuguese, Arabic, Russian, German, Albanian, Turkish, Romanian, Cantonese and Mandarin among them. Verified live 2026-09-07. [s1] | 2/2 |
Communication & Service
8.5 / 10
How easy it is to contact the clinic, get answers, and book - especially for international patients.
| ✓ | WhatsApp / LINE available Working WhatsApp links (wa.me/41765637908 and a second group number) are published on the clinic's own pages. [s1] | 2/2 |
| ? | Response speed No response-time data available in this pass. | 0/1.5 |
| ✓ | English spoken The branch roster lists English among the languages spoken by every dentist on it, and the group runs a complete English site. [s1] | 2.5/2.5 |
| ✓ | Pre-visit consultation possible The group publishes a free-quote route and states that an estimate is drawn up before each treatment and will not be exceeded; online booking is keyed per branch. [s1] [s2] | 1.5/1.5 |
| ✓ | Clear service explanations Each treatment has its own page and the pricing page explains what each package contains in plain language. [s2] | 1/1 |
| ✓ | Convenient opening hours Hours published on the branch's own Google Business record run 7 AM–9 PM, i.e. well into the evening. [gmp1] | 1.5/1.5 |
AI & Search Visibility
6 / 10
Whether the clinic is discoverable when patients search - including via AI assistants. Checked with fixed queries: "best dentist Switzerland", "English speaking dentist Switzerland", "dental implants Switzerland", "emergency dentist Switzerland", "Switzerland dental clinic for expats".
| ✓ | Mentioned for: best dentist Switzerland Web search results for "best dentist Geneva Switzerland" collected centrally on 2026-09-07 (re-run with a country qualifier). The clinic's own Geneva page cliniquehygienedentaire.ch/en/chd-geneva/ is returned at rank 3. [bsq1] | 1/1 |
| ✗ | Mentioned for: English speaking dentist Switzerland Web search results for "English speaking dentist Geneva" collected centrally on 2026-09-07. All ten results are on-target for Geneva, Switzerland, so this is a checked negative; the clinic does not appear. [bsq2] | 0/1 |
| ✗ | Mentioned for: dental implants Switzerland Web search results for "dental implants Geneva Switzerland" collected centrally on 2026-09-07 (re-run with a country qualifier). The clinic does not appear in the returned list. [bsq3] | 0/1 |
| ✗ | Mentioned for: emergency dentist Switzerland Web search results for "emergency dentist Geneva" collected centrally on 2026-09-07; four of the eight results are on-target for Geneva, Switzerland, so this is a checked negative. The clinic does not appear. [bsq4] | 0/1 |
| ? | Mentioned for: Switzerland dental clinic for expats Query not run in the AI-visibility pass: the query budget ran the expats query only for the first research city of each country, which for Switzerland was Zurich. | 0/1 |
| ✓ | Structured data on website Two schema.org JSON-LD blocks per page carrying Dentist, PostalAddress, FAQPage and SiteNavigationElement types; the same markup also embeds a self-declared AggregateRating, which was not used as data. [s1] | 1.5/1.5 |
| ✓ | Google indexing quality A name-and-address search returns the group's own domain at ranks 1, 2, 3, 8, 9 and 13 of twenty, with the Cornavin branch page first, alongside its own Facebook and LinkedIn channels (web search 2026-09-07). [giq1] | 2/2 |
