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 The price list carries only code WX003, 'sedaatio tai kivunlievitys ilman anestesiologia' — sedation or pain relief without an anaesthetist — which is conscious sedation and does not meet this criterion's definition of a patient asleep and unaware. [s2]

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 Opened and read on 2026-09-07: a current site with a combined service-and-price page, staff profiles, blog and contacts. [s1] | 4/4 |
| ✓ | Dentist names listed Six dentists named with individual profile pages, plus the hygienists and the managing director, who is himself one of the dentists. [s3] | 3/3 |
| ✓ | Dentist specializations listed Each dentist's profile states their areas of expertise — ceramic restorations, prosthetics, implants, root canal treatment, aligner orthodontics, trauma and anxious-patient care — and the clinic states it also offers erikoishammaslääkäri (specialist) services. [s3] | 2/2 |
| ✓ | Real clinic photos The place page carries an owner photo set and its lead image, read in a browser on 2026-09-08, is the practice's own team — six members of staff in navy uniforms — behind the clinic's own «HAMMASVAHTI» wordmark and tooth logo. Team and signage together, so the criterion is met. [gmpb] | 2/2 |
| ✓ | Service list published Nine service groups, each explained above its own price block: basic procedures, scaling, fillings and crowns, root canal treatment, stomatognathic physiology, extractions, implants and prosthetics, orthodontics, aesthetic treatment and physiotherapy. [s2] | 3/3 |
| ✓ | Clear contact details Phone, e-mail, street address and opening hours published, with the staff e-mail convention explained; consistent with the Google place record. [s4] | 2/2 |
| ✓ | English website version The site declares an English (en-GB) alternate and carries an "English (UK)" switcher in the header and footer. Opened on 2026-09-07 to confirm it renders rather than only being declared: https://hammasvahti.fi/en/ returns HTTP 200 with html lang="en". [s1] | 2/2 |
| ✓ | Address and map published Street address and opening hours on a dedicated contacts page and in the footer of every page. [s4] | 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 Standing price list itemised by official procedure code (SAA02, SFA00, SDA01…) with price, Kela reimbursement and patient's share, valid until further notice; the 15 € per-visit service fee, the roughly 30 % specialist uplift and the 10 %/20 % weekend surcharges are all disclosed. [s2] | 3/3 |
| ✓ | Cleaning price listed Parodontologinen hoito by hygienist 38–160 € and by dentist 50–316 €, banded by duration. [s2] | 2/2 |
| ✓ | Filling price listed Pieni täyte 70 €, up to 199 € for a large composite filling. [s2] | 2/2 |
| ✓ | Crown price listed Hammasterä tai kruunu 250 € (direct technique); Cerec ceramic crown 708 €, demanding anterior crown 781 €. [s2] | 2/2 |
| ✓ | Implant price listed Implantointi from 2300 € including laboratory costs, with surgical guide, bone graft and sinus lift priced separately. [s2] | 2/2 |
| ✓ | Consultation price listed Suun perustutkimus 75 €, limited examination 50 €, specialist examination from 139 €; orthodontic and whitening consultations free. [s2] | 2/2 |
| ✓ | X-ray / imaging price listed Intraoral 49 €, bite-wing 30 €, panoramic 105 €, cone-beam 115–220 €. [s2] | 2/2 |
Reputation & Reviews
18 / 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 on the place page in a browser on 2026-09-08. Unchanged from the automated reading of 2026-09-07. The star histogram — 111 five-star, 3 four-star, 0 three-star, 0 two-star and 0 one-star — sums to 114, matching the 114 in the place-page header exactly, and its weighted mean 4.974 reproduces the published 5.0. [gm1] [gmpb] | 6/6 |
| ◐ | Google review volume Read live on 2026-09-08 from the place-page header, and the star histogram sums to the same figure. The card carried no count before this pass: the automated map method used in the initial data collection returns the rating but never the review count on this listing, which is why it was queued for a manual browser check. [gm1] [gmpb] | 2/3 |
| ✓ | Review recency The newest review visible is two weeks old, which proves the within_3_months bucket and no better. Visible dates: 2 weeks, then 1, 2, 3, 4 and 5 months, then 1 and 1 years. Sample: the eight reviews Google Maps renders on the place page in its own relevance order — the "Newest" sort does not open to automation, so a review more recent than the newest one visible may exist. [gmpb] | 3/3 |
| ✓ | Clinic responds to reviews The owner answers seven of the eight of the reviews visible on the place page on 2026-09-08. Sample: the eight reviews Google Maps renders on the place page in its own relevance order — the "Newest" sort does not open to automation, so a review more recent than the newest one visible may exist. [gmpb] | 2/2 |
| ✓ | No recurring complaints The listing carries no one-star, two-star or three-star rating at all — the whole distribution is 111 five-star and 3 four-star ratings — so there is no negative account anywhere on the record to carry a complaint, and the criterion is false on a complete distribution rather than on a sample. The one- and two-star mass is 0 of 114. Sample: the eight reviews Google Maps renders on the place page in its own relevance order — the "Newest" sort does not open to automation, so a review more recent than the newest one visible may exist. [gmpb] | 2/2 |
| ✓ | No suspicious review patterns Judged on the histogram shape, the spread of dates, the variety of reviewers and the wording, on 2026-09-08. A near-wall on a three-figure base (111/3/0/0/0 on 114) and it is disclosed as such rather than explained away. Against a manipulation reading: three four-star ratings exist, so the distribution is not uniform; the visible dates run from two weeks to over a year without clustering in any one month; the accounts are written in at least two languages, run from three words to several sentences and describe different work including extractions; and the owner answers seven of the eight individually. The count had never been read before this pass — six automated query shapes returned the 5.0 but never the base — so a rating that read as unanchored now rests on a measured 114. [gmpb] | 2/2 |
| ✓ | Active Facebook presence The clinic links its own Facebook page from the footer of every page, alongside Instagram and LinkedIn. [fb1] | 1/1 |
| ✗ | TripAdvisor presence No TripAdvisor listing found via its search for "Hammasvahti Oulu" and "Hammasvahti Dental"; the clinic's site does not link to TripAdvisor (checked 2026-10-05). [hammasvahti-oulu-tripadvisor] [hammasvahti-oulu-tripadvisor-2] | 0/0.5 |
| ✗ | Other review platforms No profile on WhatClinic or Trustpilot, and Dental Departures and Bookimed list no Finnish clinics; no Yelp page was found under its name, nor a Finnish dentist-review site with reviews of its own. [hammasvahti-oulu-deepen] [hammasvahti-oulu-deepen-2] [hammasvahti-oulu-deepen-3] [hammasvahti-oulu-deepen-4] | 0/0.5 |
Medical Infrastructure
11.5 / 15
The range of publicly documented equipment and services. This measures documented availability, not clinical quality.
| ✓ | On-site X-ray Intraoral, bite-wing and panoramic imaging priced by procedure code. [s2] | 2/2 |
| ✓ | CBCT (3D imaging) Kartiokeilatutkimus (cone-beam CT) priced for single teeth (115 €), one to two jaw halves (195 €) and three to four (220 €). [s2] | 2/2 |
| ✓ | Implantology Implant placement, surgical guides, bone grafts and sinus lifts all priced. [s2] | 2/2 |
| ✓ | Orthodontics Suresmile aligner orthodontics with a free consultation and priced retention appliances. [s2] | 2/2 |
| ✓ | Oral surgery Implant surgery, bone grafting and sinus lift priced; extractions are a separate priced group. [s2] | 2/2 |
| ✗ | Pediatric dentistry Children's dentistry is not named among the nine service groups or in the price list. [s2] | 0/1.5 |
| ✓ | Emergency care The clinic is open at weekends and its price list explicitly prices weekend and Sunday emergency surcharges, i.e. it runs an out-of-hours reception. [s2] [s4] | 1.5/1.5 |
| ? | Works with international patients The clinic keeps a non-Finnish version of its site, but nothing in its own channels documents experience with foreign patients — no statement about international insurance, cross-border reimbursement, English paperwork or treating patients from abroad. Re-read 2026-09-07 and left unassessed rather than recorded as a negative. [s1] [s4] | 0/2 |
Communication & Service
8.5 / 10
How easy it is to contact the clinic, get answers, and book - especially for international patients.
| ✓ | WhatsApp / LINE available The clinic runs a WhatsApp chat widget (the JoinChat plugin) on its own site ("Tarvitsetko apua? WhatsApp — Avaa chat"), present in the footer of every page. Read directly on 2026-09-09: the widget's own `data-settings` JSON, embedded in the served page, carries `"telephone":"358413154131"` — the plugin does not inject the number at runtime, it is present statically, just not as a visible wa.me link. contacts.whatsapp filled from it. [s4] [s5] | 2/2 |
| ? | Response speed | 0/1.5 |
| ✓ | English spoken The clinic maintains an English version of its site. [s1] | 2.5/2.5 |
| ✓ | Pre-visit consultation possible Free orthodontic and whitening consultations are published as bookable items, and the clinic invites patients to contact it for a more exact estimate. [s2] | 1.5/1.5 |
| ✓ | Clear service explanations Each price block is preceded by a plain-language explanation of the treatment and, for scaling, of what periodontitis is. [s2] | 1/1 |
| ✓ | Convenient opening hours Confirmed on the clinic's own Google Business Profile, read in a browser on 2026-09-08, which publishes the full week: Monday to Friday 08:00–19:00 and both Saturday and Sunday 10:00–14:00. That agrees exactly with the contacts page and footer of the clinic's own site, so evening surgery and seven-day opening are published clearly on both of its channels. [s4] [gmpb] | 1.5/1.5 |
AI & Search Visibility
3.5 / 10
Whether the clinic is discoverable when patients search - including via AI assistants. Checked with fixed queries: "best dentist Finland", "English speaking dentist Finland", "dental implants Finland", "emergency dentist Finland", "Finland dental clinic for expats".
| ✗ | Mentioned for: best dentist Finland The canonical city query was run in the AI-visibility pass on 2026-09-07; the clinic does not appear in the returned result list, which is held by national chains, the city and wellbeing-county pages, Wikipedia and directories. [bsq1] | 0/1 |
| ✗ | Mentioned for: English speaking dentist Finland The canonical city query was run in the AI-visibility pass on 2026-09-07; the clinic does not appear in the returned result list, which is held by national chains, the city and wellbeing-county pages, Wikipedia and directories. [bsq2] | 0/1 |
| ✗ | Mentioned for: dental implants Finland The canonical city query was run in the AI-visibility pass on 2026-09-07; the clinic does not appear in the returned result list, which is held by national chains, the city and wellbeing-county pages, Wikipedia and directories. [bsq3] | 0/1 |
| ✗ | Mentioned for: emergency dentist Finland The canonical city query was run in the AI-visibility pass on 2026-09-07; the clinic does not appear in the returned result list, which is held by national chains, the city and wellbeing-county pages, Wikipedia and directories. [bsq4] | 0/1 |
| ? | Mentioned for: Finland dental clinic for expats The fifth canonical query was not run for this city in the AI-visibility pass: the pass ran it only for the first research city of each country (Helsinki for Finland). Left unset rather than guessed. | 0/1 |
| ✓ | Structured data on website The site's schema.org JSON-LD graph carries a business-level Organization entity for the practice ("Hammasvahti") alongside the generic WebPage/WebSite/BreadcrumbList nodes. Re-read on 2026-09-07: that Organization node carries the business name, the site URL and, where present, its social profiles — but no PostalAddress, no telephone and no geo. It is therefore not LocalBusiness or Dentist markup; it is credited under the criterion's "or equivalent" wording as business-level structured data. [s1] | 1.5/1.5 |
| ✓ | Google indexing quality The clinic's own domain holds the first result for its own name and three of the first seven (front page, staff page, a named dentist's profile); the rest are its own social profiles, a partner gym's recommendation and press coverage. [giq1] | 2/2 |
| ✗ | Dedicated service pages Services are explained in blocks on one combined price-and-services page rather than on individual pages; only the dentists have pages of their own. [s2] | 0/1.5 |
