Changelog
Every data update, correction, and methodology change is logged here and in each clinic's own change history. The rating updates whenever the underlying public data changes.
| Date | Subject | Change |
|---|---|---|
| 2026-09-01 | 0900Dentist | Re-read of the clinic's website and Google listing following the clinic's free-check request of 2026-08-19: full NZa price list found on /rates/price-list (324 priced codes, rendered by script) and special-offer prices in HTML - all seven price criteria recorded; team page recorded (four dentists, one implant specialist); CBCT and digital X-ray, Invisalign, WhatsApp, emergency page and structured data on treatment pages recorded; nitrous-oxide sedation priced (no GA) - recorded; opening hours Mon-Fri 09:00-17:00 only - recorded as not convenient; Google rating refreshed (4.7 from 362, owner replies). BIG numbers for two dentists taken from the tandarts.nl listing (not published on the clinic site). |
| 2026-08-25 | 0900Dentist | Re-verification 2026-08-25: confirmed website live, address and phone unchanged, clinic open; Google review count moved 303→361, rating steady at 4.7. |
| 2026-08-25 | AltaDent Clinic Amsterdam | Re-verification 2026-08-25: confirmed website live, address and phone unchanged, clinic open; recorded new Google rating 4.9 (28 reviews) — previously unset. |
| 2026-08-25 | Amstel Dental | Re-verification 2026-08-25: confirmed website live, address and phone unchanged, clinic open; Google review count moved 245→315, rating steady at 4.3. |
| 2026-08-25 | Amsterdams Centrum voor Cosmetische Tandheelkunde (ACCT) | Re-verification 2026-08-25: confirmed website live, phone unchanged, clinic open; corrected postal code to 1063 ES (was recorded as 1063 BE) per Google Maps profile; recorded new Google rating 4.6 (114 reviews) — previously unset. |
| 2026-08-25 | Amsterdams Centrum voor Cosmetische Tandheelkunde (ACCT) | License verification 2026-08-25: clinic license found via Zorgaanbiedersportaal after correcting a postcode error in clinics.json (KvK 33211553, address-matched). BIG-register confirms Deirdre Beekmans and Freek Gols Linthorst as registered Tandarts; Bart Beekmans left null — no B-initial match among 5 Beekmans/Beekman BIG entries. |
| 2026-08-25 | De Amsterdamse Tandarts | Re-verification 2026-08-25: confirmed website live, address and phone unchanged, clinic open; Google review count moved 134→271, rating steady at 4.7. |
| 2026-08-25 | Dental Clinics Amsterdam Reguliersgracht | Re-verification 2026-08-25: confirmed website live (incl. general-anaesthesia treatment page), address and phone unchanged, clinic open. Google listing observed at 4.5 stars / 333 reviews on Maps, but a compliant place-URL source could not be captured this session due to a persistent Maps loading fault on the duplicate-listing search, so the rating/review-count/geo were left unrecorded rather than sourced to a search-results URL. |
| 2026-08-25 | Dental Clinics Amsterdam Reguliersgracht | Recorded sedation / general anaesthesia availability (informational): documented as available. Chain's narcose-tandarts page: sleep medication given, patient briefly 'away' and notices nothing of the treatment |
| 2026-08-25 | Dental Clinics Amsterdam Reguliersgracht | License verification 2026-08-25: BIG-register confirms all 3 named doctors as registered Tandarts, two under name variants (Dietvorst's compound married/maiden surname; Elenblaas's spelling matched only as 'Elenbaas'). Clinic-level registry lookup not performed this pass. |
| 2026-08-25 | Dental Practice Jacob Obrecht | Re-verification 2026-08-25: website live (was closed for renovation until 2026-08-19, now reopened and shown open on Maps); recorded previously-unpublished street address and phone number from its Google Maps profile; Google review count moved 130→182, rating steady at 4.9. |
| 2026-08-25 | Dental Practice Jacob Obrecht | License verification 2026-08-25: no BIG-register match for 'Obrecht'; the clinic's own website confirms 'Jacob Obrecht' is used only as a brand/street-derived practice name, not a named dentist, so the doctor entry is left null. Clinic-level registry lookup not performed this pass. |
| 2026-08-25 | Expat Orthodontics Amsterdam | Re-verification 2026-08-25: confirmed website live, address and phone unchanged, clinic open (listed on Google as "Orthodontiepraktijk Amsterdam Zuid", the Dutch trading name of Expat Orthodontics); recorded new Google rating 4.3 (220 reviews) — previously unset. |
| 2026-08-25 | Lassus Tandartsen | Re-verification 2026-08-25: confirmed website live, address and phone unchanged, clinic open; Google rating moved 4.2→4.3 and review count 765→868. |
| 2026-08-25 | Methodology v1.3.0 | Corrected how the two licensing red flags are applied ("Clinic operating licence not published" and "Dentists / their licences not listed"). Previously they were applied whenever licensing data was absent from our records, which treated unchecked data as a negative finding — contrary to the methodology's own rule that unverified data is a fact about our coverage, not about the clinic. Both flags now apply only where we have verified that the information is not published. Manual licensing flags that rested on unverified data were removed from the affected clinics. No other scoring rules changed; most scores rise because the incorrect penalty is removed. |
| 2026-08-25 | MOQM Dental | Re-verification 2026-08-25: confirmed website live, address and phone unchanged, clinic open; recorded new Google rating 4.8 (94 reviews) — previously unset. |
| 2026-08-25 | Tandarts Jordaan | Re-verification 2026-08-25: confirmed website live, address and phone unchanged, clinic open; recorded new Google rating 4.3 (619 reviews) and pin coordinates — previously unset. |
| 2026-08-25 | Tandarts Jordaan | License verification 2026-08-25: BIG-register confirms all 4 named doctors as registered Tandarts (Vaartjes, Doghri, Petras, Betti). No clean match for the clinic itself in Zorgaanbiedersportaal under its trading name or a broader 'Jordaan' search — left null, not false, since the registered legal entity name is unknown. |
| 2026-08-25 | Tandartspraktijk Apollo | Re-verification 2026-08-25: confirmed website live, address and phone unchanged, clinic open; recorded new Google rating 4.8 (84 reviews) — previously unset. |
| 2026-08-25 | Tandartspraktijk Apollo | License verification 2026-08-25: BIG-register confirms Veronique van der Lee as a registered Tandarts. Roderik van Rens left null (2 same-initial candidates, cannot disambiguate); Sabine Leijten left null (0 results under 2 spelling variants). Clinic-level registry lookup not performed this pass. |
| 2026-08-25 | Tandartspraktijk De Liefde | Re-verification 2026-08-25: confirmed website live, address and phone unchanged, clinic open; recorded new Google rating 4.4 (496 reviews) — previously unset. |
| 2026-08-25 | The Dentist Amsterdam | Re-verification 2026-08-25: confirmed website live, address and phone unchanged, clinic open; Google rating moved 4.7→4.9 and review count 130→93 (lower count likely reflects Google's periodic review filtering). |
| 2026-08-25 | TTH van Wou Tandartsenpraktijk | Re-verification 2026-08-25: confirmed website live, address and phone unchanged, clinic open; recorded new Google rating 4.5 (271 reviews) — previously unset. |
| 2026-08-23 | Methodology v1.2.0 | Added an informational "Sedation & general anaesthesia" availability field to every clinic and a new "Sleep Dentistry (Sedation / GA)" list, for patients who cannot tolerate — or would rather not be awake for — treatment. This field is informational and does not change any transparency score. |
| 2026-07-08 | Methodology v1.1.0 | Added licensing transparency: clinics are now penalised when they do not publish their operating licence, or do not list their dentists together with their professional licence numbers. Each clinic page now shows a Licensing & Credentials section. |
| 2026-07-03 | Methodology v1.0.0 | Initial public methodology. |
