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) — Not verified 'Sedation' listed only as an appointment-form dropdown option; oral-surgery/implant pages have no anaesthesia detail at all.

Change History
| Date | Change |
|---|---|
| 2026-10-05 | Other review platforms re-checked on 2026-10-05: the DocDental page cited before only reproduces Google reviews; Doctify has only an unclaimed page without reviews and no profile was found on WhatClinic or Trustpilot; changed from yes to no. |
| 2026-09-24 | Re-read the clinic's website (fees, team, contact, check-ups and oral-surgery pages) and its Google listing. Recorded: named dentists with GDC numbers; a genuine clinician photo; consultation, hygiene, filling, crown and implant prices (no separate X-ray charge); X-rays taken as part of check-ups; a linked Facebook page; a children's hygiene fee; an online appointment-request form. Google reviews: newest within 3 months, owner replies to reviews, and no recurring complaint theme among the small number of low ratings. No TripAdvisor presence found. No WhatsApp contact and no documentation of treating international/overseas patients. Still unverified: whether the CT scan mentioned for implant planning is taken at this practice. |
| 2026-09-09 | Editorial gate: the pseudo-source "sq" (url "search:...London", the 2026-07-10 AI/search-visibility scout) was removed from 1 criterion field outside aiVisibility, where it had been co-cited beside a real piece of evidence. Every real source on those fields is kept and no value changed; the sq citation inside criteria.aiVisibility.googleIndexingQuality, where a search query is the legitimate evidence, is left in place. Raised by the E1 assertion pass (e1-report.md deviation 1). |
| 2026-08-26 | Deepen 2026-08-26: rechecked website/contacts/operating status (all confirmed, open) and CQC registration (still active); Google Maps rating newly captured (4.9/199, previously unset) with geo pin and place URL - notably 2 reviews flagged brand-new within the last 2-3 weeks; added 2 external sources (Google Maps, fresh CQC re-verification); visibility scout 5 queries (all false today); no uncited sources on this clinic. |
| 2026-08-25 | License verification 2026-08-25 against CQC: clinic CQC registration found (1-3957725008, exact address and phone match). No individual dentists are named on the clinic site, so no GDC doctor lookups were possible. |
| 2026-07-10 | Initial data collection. |
