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
Summary
Private practice in St. Alban-Vorstadt run by a Swiss-British dental surgeon, publishing English, German and Spanish versions and one of the most complete public price lists in Basel: two tables covering roughly forty treatments and the hygiene programme, with the SSO tariff point value stated alongside. The dentist holds an active Basel-Stadt practice authorisation recorded in MedReg. The practice is not in the federal BetReg facility register, which for Basel lists only the university clinics.

Score Breakdown

Information Transparency
20 / 20
Whether basic facts about the clinic - its team, premises, services, and location - are publicly verifiable.

| ✓ | Clear contact details Street address, telephone +41 61 271 06 04, a second mobile number, an online booking link and a contact page are published on the site. [s1] | 2/2 |
| ✓ | English website version The site is published in English first, with German and Spanish versions linked from every page. [s1] | 2/2 |
| ✓ | Address and map published The site publishes the postal address and links its own Google place by place id from the page. [s1] | 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 The practice publishes two permanent price tables of its own: a treatment list of roughly forty lines from consultation and X-ray through extractions, root canal treatment, fillings, inlays, veneers, implants, orthodontics and a full smile makeover, and a separate dental-hygiene list; it states the SSO Denotar tariff point value of CHF 1.70, that material and anaesthesia are included, and that prices may vary by up to ten per cent. [s3] | 3/3 |

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) Re-read live on the place page in a browser on 2026-09-08 and unchanged at 4.7. The star histogram's weighted mean, 4.664, reproduces the published figure. [gmp1] [gmpb] | 5/6 |
| ◐ | Google review volume Headline count read on the place page in a browser on 2026-09-08. The histogram sums to the same figure: 210 five-star, 5 four-star, 2 three-star, 2 two-star and 16 one-star = 235. The 235 the practice shows in its own Google review widget is therefore accurate. [gmpb] | 2.5/3 |
| ✓ | Review recency Browser 2026-09-08, 8 visible reviews, sort: Google's own "Most relevant" order. The newest visible review is three months old; the rest run 5 to 9 months and 1 to 2 years. [gmpb] | 3/3 |
| ✓ | Clinic responds to reviews Browser 2026-09-08, 8 visible reviews, sort "Most relevant": the owner has replied to all eight, including both one-star accounts, and both of those replies have been edited since posting. [gmpb] | 2/2 |
| ✓ | No recurring complaints Browser 2026-09-08, 8 visible reviews, sort "Most relevant". Two one-star accounts are present. Only one is fully readable: a patient who says he was advised to undergo expensive procedures a second opinion later found unnecessary and was charged for a session he had not been told about. The other is truncated after its opening lines and Google's "More" control does not expand to automation, so its theme cannot be established; the owner's reply to it concerns a temporary restoration carried out to save a broken tooth. One readable negative plus one unreadable one does not establish a repeated theme. One-star and two-star ratings together are 18 of 235, or 7.7 per cent of the base. [gmpb] | 2/2 |
| ✓ | No suspicious review patterns Browser 2026-09-08: histogram 210/5/2/2/16 with a mean of 4.664 against a published 4.7; a real critical tail is present and answered, dates are spread over years and the wording varies. No manipulation signature. [gmpb] | 2/2 |
| ✓ | Active Facebook presence The practice links its own Facebook page facebook.com/english.dentist.basel from its site. [s1] | 1/1 |
| ✗ | TripAdvisor presence No TripAdvisor listing found via its search for "Basel’s English Dentist" and "Basel’s English"; the clinic's site does not link to TripAdvisor (checked 2026-10-05). [basels-english-dentist-dr-garry-bonsall-basel-tripadvisor] [basels-english-dentist-dr-garry-bonsall-basel-tripadvisor-2] | 0/0.5 |
| ✓ | Other review platforms Has its own clinic profile on WhatClinic (20 verified patient reviews, 4.9). [basels-english-dentist-dr-garry-bonsall-basel-platforms] | 0.5/0.5 |
Medical Infrastructure
13 / 15

| ✓ | Oral surgery The published price list carries surgical extraction, wisdom-tooth osteotomy and gum flap surgery. [s3] | 2/2 |
| ✓ | Pediatric dentistry The team page publishes a named hygienist for children’s prevention and bleaching, and the price list carries fluoridation for children and fissure sealing per tooth. [s2] [s3] | 1.5/1.5 |
| ✓ | Emergency care "Emergency dental service" is one of the categories the practice publishes on its own Google Business Profile. [gmp1] | 1.5/1.5 |
| ✓ | Works with international patients The practice is published as Basel’s English-Swiss dentist, runs its site in English, German and Spanish and states it treats local and international patients. [s1] [s2] | 2/2 |
Communication & Service
3.5 / 10
How easy it is to contact the clinic, get answers, and book - especially for international patients.
| ✗ | WhatsApp / LINE available No WhatsApp, Line or comparable messaging channel is published on the practice’s own site; contact runs through the telephone numbers, the form and online booking. [s1] | 0/2 |
| ? | Response speed | 0/1.5 |
| ✓ | English spoken The practice publishes its site in English and describes itself as Basel’s English-speaking dentist. [s1] | 2.5/2.5 |
| ? | Pre-visit consultation possible | 0/1.5 |
| ✓ | Clear service explanations Each treatment family has its own page, and the price list states in plain terms what each price includes, that material and anaesthesia are covered and that figures may vary by up to ten per cent. [s1] [s3] | 1/1 |
| ✗ | Convenient opening hours The full published week was read on the practice's own Google Business record in a browser on 2026-09-08: Monday to Thursday 08:30-17:30 and Friday 08:30-15:00, closed Saturday and Sunday. No evening or weekend surgery. [gmpb] | 0/1.5 |
