Cookie policy
Cookies and similar technologies help our site work and help us understand how it's used. Essential ones are always on; everything else is your choice, and you can change it any time.

Use the panel below to turn non-essential cookies on or off. Your choice is saved on your device and applies across the site. You can reopen this from "Cookie settings" in the footer.

What cookies are
Cookies are small files stored on your device. "Similar technologies" such as local storage, pixels and SDKs work in comparable ways, and UK rules (PECR) treat them similarly. Non-essential technologies are only used with your consent.
The categories we use
| Category | Purpose | Consent needed? |
|---|---|---|
| Strictly necessary | Security, core functionality, remembering your cookie choice | No (exempt) |
| Analytics | Understanding how the site is used so we can improve it, including recordings of clicks, taps and scrolling with anything you type hidden. Provided by Google Analytics 4 and Microsoft Clarity. Clarity never runs on sign-in, invitation or payment pages | Yes |
| Functional | Remembering preferences you set, such as a location. None are in use today, the choice is here so it stays your decision if we add one | Yes |
We don't use advertising cookies, and we don't sell or share your data with advertising networks. Microsoft Clarity can set some cookies on Microsoft's own websites, listed below. We tell Clarity that you have not agreed to advertising storage.
Specific cookies
Our own two entries are stored in your browser's local storage rather than as cookies, but they do the same job, so we list them here too. The analytics cookies are only ever set if you accept analytics.
| Name | Provider | Purpose | Expiry |
|---|---|---|---|
| dl_cookie_consent | Dentist Locator | Records that you've made a cookie choice, so we stop asking | Stays until you change your choice or clear your browser |
| dl_cookie_prefs | Dentist Locator | Records which categories you accepted | Stays until you change your choice or clear your browser |
| _ga | Google Analytics | Tells one visitor's browser apart from another | 2 years |
| _ga_<id> | Google Analytics | Keeps track of a single visit | 2 years |
| _clck | Microsoft Clarity | Keeps the same Clarity visitor ID and preferences for this site | 1 year |
| _clsk | Microsoft Clarity | Joins the pages you view into one recorded visit | 1 day |
| CLID | Microsoft Clarity, on Microsoft's website | Records the first time Clarity saw this browser on any site that uses Clarity | Microsoft does not publish this |
| MUID | Microsoft, on Microsoft's website | Tells browsers visiting Microsoft sites apart. Microsoft uses it for advertising, site analytics and other operational purposes | Microsoft does not publish this |
| MR | Microsoft, on Microsoft's website | Tells Microsoft whether to refresh MUID | Microsoft does not publish this |
| SM | Microsoft, on Microsoft's website | Keeps MUID the same across Microsoft's websites | Microsoft does not publish this |
| ANONCHK | Microsoft, on Microsoft's website | Shows whether MUID is passed to an advertising cookie. Clarity does not use that cookie, so this is always set to 0 | Microsoft does not publish this |
Other ways to control cookies
Besides the panel above, most browsers let you block or delete cookies in their settings. Blocking strictly-necessary cookies may stop parts of the site working. Clearing your browser data will reset your saved choice, and we'll ask again.
