Anestesia general y sedación profunda
Si la clínica documenta tratamientos bajo anestesia general o sedación profunda / crepuscular — la «odontología del sueño», en la que el paciente duerme y no percibe nada (no siente, ve ni oye el procedimiento). La sedación consciente ordinaria, en la que el paciente permanece despierto y receptivo, no cuenta aquí. Es información orientativa y no afecta a la puntuación de transparencia.
- ? Anestesia general / sedación profunda (odontología del sueño) — No verificado FAQ lists 'Sedation Dentistry' among services offered, but no page specifies depth (asleep vs conscious)
Resumen
Clínica de larga trayectoria en Tijuana que ofrece implantes, All-on-4, odontología cosmética, endodoncia y ortodoncia con un equipo de especialistas nombrado. Personal que habla inglés; la página principal carece de datos de contacto, que se encuentran en una página de contacto separada.
Alongside the real staff page, the site still serves theme template pages at /team/ with invented dentists, lorem ipsum text, the placeholder phone 1800 (123) 4567 and john@dentalcare.com (read 2026-10-20).

Historial de cambios
| Fecha | Cambio |
|---|---|
| 2026-10-20 | Re-read on 2026-10-20 together with the other neighbours of The Special Teeth, which asked for the free check (lead of 2026-10-19), as the rule of 2026-09-14 requires. Google listing read in two review sorts: rating 4.9 from 103 reviews, newest review 2026-09-18. Review responses are now read rather than unknown: the owner-reply block carries no reply on any of the ten reviews rendered. The site still serves unedited theme pages with invented dentists next to its real staff page. Visibility re-read with the same run: the clinic is no longer among the results for the search for an English-speaking dentist and the search for dental implants. The five canonical Tijuana queries were read once on 2026-10-20 for every clinic of the list. |
| 2026-10-05 | Facebook presence checked on 2026-10-05: the clinic's identified page has not posted since 2024-03-07 and has 4 reviews, while the clinic's website is live. |
| 2026-09-29 | Corrected 2026-09-29: review recency within 3 months (newest review dated 2026-09-18). |
| 2026-09-25 | Search visibility checked on 2026-09-25 for the four pending Tijuana queries: present for "English speaking dentist Tijuana", "dental implants Tijuana"; not present for "emergency dentist Tijuana", "Tijuana dental clinic for expats". |
| 2026-09-25 | Re-read on 2026-09-25: Corrected: a full price list is now published on a dedicated page, covering cleaning, fillings, crowns, implants, a free consultation and X-rays; No CBCT or pediatric dentistry found anywhere on the site; walk-in patients welcomed; No WhatsApp/LINE contact found; Structured business data present; Google 4.9 from 104 reviews; no recurring-complaint theme (each negative review describes a different issue). Still unverified: whether the owner replies to reviews, a Facebook page. |
| 2026-08-26 | License verification 2026-08-26 against RNP and CLUES: both confirmed unreachable/non-functional today. CLUES clinic-registry search not executable for 'Dental Solutions Tijuana'; RNP dentist-registry search not executable for 5 named doctors. No new registry matches found; existing licensing data left unchanged. |
| 2026-08-25 | Re-verification 2026-08-25: website live; address confirmed via Maps (Calle 11 8691-A), phone confirmed via a Yelp listing matching the stored number exactly (site itself is JS-rendered and didn't expose contact text to the fetcher); captured Google rating 4.9 (103 reviews, was unset) and place URL/coordinates. Sedation research: site's FAQ lists 'Sedation Dentistry' among services without specifying depth, left as null. |
| 2026-07-10 | Initial data collection. |
