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 Conflicting community reports: one Facebook comment says the clinic does not offer general anaesthesia, another consumer post implies it was used - no reliable single source, left unknown.

Change History
| Date | Change |
|---|---|
| 2026-09-29 | Checked TripAdvisor's own search and the clinic's website for a TripAdvisor profile: the site's only "tripadvisor" occurrence is an unused icon-sprite id from a reviews-widget plugin, not a real link; no matching profile found. |
| 2026-09-17 | Re-read on 2026-09-17: the clinic's website is now directly reachable (previously not directly fetchable) — its X-ray diagnostics, team, contacts, services, crown and implant/surgery pages in English, plus its Google listing. Recorded: no prices published anywhere despite an extensive site; own digital segmental/panoramic X-ray equipment, no CBCT; children's orthodontic treatment offered; no WhatsApp; an online booking form with file upload; hours to 20:00 on weekdays; Organization structured data; own-hosted team photos. Google reviews are recent, individually answered even when critical, and show no signs of manipulation. Still unverified: TripAdvisor presence; a documented same-day emergency service (not a Google Business Profile category and only incidental 'emergency' wording in unrelated blog posts). |
| 2026-09-10 | Name-verification pass 2026-09-10 (browser): 'Dr. Karteva' appears neither on the clinic’s own exhaustive fourteen-person team page (impressiondent.com/ekip/, read 2026-09-10) nor in the BZS national register under the Cyrillic spelling of Karteva at all (surname searches for Karteva and Kartev in that spelling both return 0 in a real browser, with a passing positive control Ivanov → 430); the one Sofia dentist whose surname romanises to “Karteva” under the statutory transliteration and whose specialty is endodontics — Dr. Teodora Georgieva Karteva (a different Cyrillic spelling of the surname), LPK 160010843 — is registered at a different practice, Sofia, bul. Tsarigradsko shose № 96, not at 13 Henrik Ibsen St.; removed. |
| 2026-08-26 | Deepen 2026-08-26: rechecked website/contacts/operating status (unchanged); added Google rating (4.8/220) and a Bulgarian dental-clinics Facebook community discussion as external sources; recorded a recurring-complaints pattern (pricing/quality) visible across two independent Google reviews plus the community thread (previously null); visibility scout 5 queries - appears only for expats; sedation left null - one community comment said general anaesthesia is not offered, another implied it was used elsewhere in the same thread, so the evidence is contradictory and not treated as reliable; no uncited sources found to triage. |
| 2026-08-26 | License verification 2026-08-26 against BZS dentist register and IAMN/his.bg outpatient-care registry: founder Dr. Byalev confirmed active BZS member at Impression Dent's own address, with matching clinic registration found (220911200751); Yana Mohammad-Byaleva and Karteva not found under name/surname variants tried (recorded as null, not false). |
