Google has dropped its plan to remove third-party cookies from Chrome. Instead, Chrome now lets each user choose whether to allow or block them. UK dental practices should still move towards first-party data and privacy-first marketing, because cookie tracking remains unreliable in the long run.
Google’s cookie plans have changed again. For years, dentists heard that third-party cookies would soon disappear. However, that never fully happened. This guide explains what actually changed, why it matters for your practice, and what to do next. It is written in plain English, so anyone on your team can follow it.
What Are Third-Party Cookies?
Third-party cookies are small files that websites other than the one you are visiting place inside your browser. Advertisers use them to follow people across different sites. Dental practices often use them for retargeting ads, such as reminding a website visitor about teeth whitening or Invisalign.
What Actually Changed With Google’s Cookie Plans
Google first announced plans to remove third-party cookies back in 2020. After that announcement, the deadline kept slipping. Many articles predicted 2022, then 2023, then 2024, and finally 2025 as the last date. Each delay left dental practices unsure of what to plan for.
Then, in April 2025, Google changed course completely. The company confirmed it would not remove third-party cookies from Chrome after all. Instead, Chrome now offers a “user choice” model. People can block third-party cookies in their own settings if they wish. Even so, cookies stay switched on by default for most users. Google did not add a new consent pop-up either, so the change happens quietly in the background.
Furthermore, Google shut down most of its Privacy Sandbox tools in October 2025. These tools were meant to replace cookies with newer, more private technology. Only a few small pieces survived this change, such as FedCM and Private State Tokens. Meanwhile, well-known tools like Topics and Protected Audience are now gone completely.
Meanwhile, other browsers tell a very different story. Safari and Firefox already block third-party cookies by default. Brave blocks them too. Together, these browsers make up a large share of UK web traffic. So, even though Chrome kept its cookies, a good number of your patients already browse without them. In short, the cookie problem never really went away. It simply became more mixed and more confusing.
Here is why this matters for your dental practice:
- Retargeting ads on Chrome will keep working for now
- Safari and Firefox users are already cookieless
- Most Privacy Sandbox alternatives no longer exist
- UK data protection rules still apply, regardless of browser settings
- First-party data remains the safest long-term strategy
Why Google Kept Delaying the Cookie Phase-Out
Google gave a clear reason for its reversal. The UK’s Competition and Markets Authority ran extensive tests on Google’s replacement technology. The results showed real problems. Advertisers reported large drops in accuracy when measuring which ads led to bookings. Because of this, Google decided the replacement tools were not ready for wide use. Rather than force a broken system onto the whole industry, Google chose to pause the entire plan. This decision affects every business that runs ads online, including dental practices of every size.
What UK Data Protection Rules Mean For Your Practice
Even though Chrome kept its cookies, UK GDPR and the Privacy and Electronic Communications Regulations still apply. Therefore, your practice still needs clear consent banners and an honest privacy policy. In addition, patients expect transparency about how their data gets used. This builds trust, which matters greatly in healthcare marketing. Also, the Information Commissioner’s Office can still take action against websites that mislead patients about tracking. So, staying compliant is not optional, whatever Chrome decides to do next.
Overall, dental practices should treat this news as a pause, not a finish line. Cookies remain part of the picture today. However, the direction of travel is still towards more privacy and less tracking across the whole web.
Step-by-Step Guide: How Dental Practices Should Respond
Step 1: Audit your current tracking
First, check which tools on your website use third-party cookies. Your web developer or marketing partner can run this check quickly. Knowing what you use today makes future changes far easier to manage.
Step 2: Build first-party data channels
Next, collect data directly from patients. Online booking forms, email sign-ups, and loyalty schemes all create first-party data. This data belongs to you, not to a browser or an advertiser. As a result, it stays useful no matter what any browser decides next.
Step 3: Review your privacy policy and consent banners
After that, update your cookie policy so it reflects reality in 2026. Make sure your consent banner gives patients a real choice, not just an “accept all” button. This small step protects your practice from complaints and fines.
Step 4: Diversify your ad platforms
Then, avoid relying on one single ad channel. Google Ads, Meta Ads, and local SEO all work well together. As a result, your practice stays visible even if one platform changes its rules again. This spreads your risk sensibly.
Step 5: Monitor browser-level changes
Finally, keep an eye on browser updates. Chrome, Safari, and Firefox all move at different speeds. Because of this, a marketing partner who tracks these changes can save you time and stress. It also means you hear about updates before they affect your bookings.
Key Benefits of Moving Away From Cookie Dependence
- Builds stronger, more direct relationships with patients
- Protects your marketing from future browser changes
- Improves the quality of your ad targeting over time
- Supports full UK data protection compliance
- Strengthens patient trust in your brand
- Reduces reliance on any single advertising platform
Frequently Asked Questions
Has Google removed third-party cookies from Chrome?
No. In April 2025, Google confirmed it would keep third-party cookies in Chrome. Users can still choose to block them through their own settings.
Do dental practices still need to worry about cookies?
Yes, to some extent. Safari and Firefox already block third-party cookies by default. So, a large part of your website traffic may already be cookieless, even on Chrome.
What is first-party data?
First-party data is information you collect directly from your own patients. Examples include booking forms, email addresses, and appointment history.
What happened to Google’s Privacy Sandbox?
Google shut down most Privacy Sandbox tools in October 2025. Only a small number of features, such as FedCM, remain active today.
Do UK dental practices need a cookie consent banner?
Yes. UK GDPR rules apply no matter what Chrome decides to do with cookies. Your website still needs clear, honest consent options for every visitor.
Should dentists still invest in Google Ads?
Yes. Google Ads still works well for dental practices. However, pairing it with first-party data and strong SEO gives better, longer-lasting results.
Will third-party cookies ever disappear completely?
Possibly, over time. Safari, Firefox, and Brave already limit them. So, the overall trend still points towards a more private, cookieless web.
What should a dental practice do right now?
Start small. First, review your current cookie banner. Then, set up one first-party data channel, such as an email sign-up form. Finally, ask your marketing partner for a plan that covers the next twelve months, not just the next campaign.
