The Number Everyone Asks About — and Almost Everyone Misreads
Cost per lead is the number every dental practice owner asks about first. And it’s the number that’s most often misunderstood, misreported, or used out of context.
A £180 CPL for a dental implant campaign is excellent. A £180 CPL for a teeth whitening campaign is a disaster. The number without context tells you almost nothing.
This report pulls from the WordStream 2025 Google Ads Benchmarks — the largest publicly available data set, covering 16,000+ campaigns — and from aggregated UK dental campaign data published by specialist agencies running hundreds of live accounts. The aim is to give UK practices an honest picture of what performance looks like, by treatment type, by location, and by campaign quality.
01 — Industry Benchmarks: Where Dentistry Sits vs. Every Other Industry
WordStream tracks 23 industries across Google and Microsoft Ads. In 2025, dentistry sits in an unusual position: it has the lowest click-through rate of any industry tracked, but a conversion rate above the cross-industry average. That combination tells you something important about the nature of dental search intent.
| Metric | Dental (UK) | All Industries | Best Performer | What It Means |
|---|---|---|---|---|
| Click-Through Rate | 5.44% | 6.66% | 13.10% (Arts & Ent.) | Lowest of all 23 industries — the SERP is saturated and ads look the same |
| Cost Per Click | £5.80 | £3.88 | £1.18 (Arts & Ent.) | 2nd most expensive sector behind legal — reflects patient LTV |
| Conversion Rate | 9.08% | 7.52% | 14.67% (Auto Repair) | Above average — searchers are ready to book, not just browsing |
| Cost Per Lead | £62 | £52 | £21 (Auto Repair) | High CPL reflects high LTV — the economics still work strongly |

Dental ads have the lowest CTR in any industry — not because Google Ads doesn’t work for dentistry, but because the creative is largely undifferentiated. “Quality dental care in [City]” is running in a thousand campaigns simultaneously. When ads look identical, users stop clicking. This is a creative problem, not a platform problem — and it represents a real opportunity for practices willing to do the work.
The high conversion rate (9.08%) is the more telling figure. It confirms that when dental ads do get a click, the person clicking has high intent. They’ve searched for a specific treatment, they’ve self-qualified through a long decision process, and they’re ready to make contact. The job of the ad isn’t to create interest — it’s to get out of the way and let them through.
02 — UK Benchmarks by Treatment Type
CPL Varies Dramatically by Treatment — Here’s the Full Picture
The biggest mistake in dental PPC reporting is averaging CPL across an entire account. A practice running campaigns for general check-ups, Invisalign, and dental implants simultaneously will see wildly different CPLs per treatment — and they should. What matters is whether each CPL is appropriate for that treatment’s economics.
The following table uses aggregated UK data from Wise Agency (200+ campaigns, 2023–2025), Dominate Dental, and Dentree, cross-referenced with WordStream benchmarks. The “good CPL” column represents well-optimised, top-quartile performance — not a theoretical minimum.
| Treatment Type | CPC (UK avg.) | Conv. Rate | CPL Range | Good CPL Target | Patient LTV |
|---|---|---|---|---|---|
| General / check-ups | £2–£5 | 7–10% | £35–£85 | Under £50 | £2,500–£4,000 |
| Emergency dentistry | £3–£8 | 9–12% | £25–£70 | Under £45 | £500–£2,000 |
| Teeth whitening | £3–£8 | 6–9% | £35–£80 | Under £50 | £300–£800 |
| Composite bonding | £5–£12 | 6–9% | £60–£120 | Under £80 | £800–£2,500 |
| Invisalign / orthodontics | £5–£15 | 6–8% | £120–£200 | Under £150 | £3,000–£6,000 |
| Dental implants (single) | £8–£25 | 5–8% | £180–£350 | Under £220 | £3,000–£8,000 |
| Full arch / All-on-4 | £15–£40+ | 4–7% | £250–£500+ | Under £350 | £12,000–£17,000 |
Sources: Wise Agency (200+ UK dental campaigns, 2023–25); Dominate Dental UK benchmarks; Dentree 2025 data; WordStream benchmarks. “Good CPL” = well-optimised, top-quartile campaign performance.
A few patterns worth noting. Emergency dentistry consistently produces the lowest CPLs — searchers are in pain and need to book immediately, so conversion intent is extremely high. General dentistry CPLs are low in absolute terms but carry the most LTV potential through patient retention and referrals over years.
Implant campaigns appear expensive until you run the full maths (see Section 4). At £2,500–£8,000+ patient LTV per case, a £220 CPL represents one of the better-returning investments in any marketing channel.
London premium: CPCs in central London and other major UK cities typically run 20–35% above the ranges in the table. London implant-related keywords have exceeded £35 per click in highly competitive postcode areas. If you’re running campaigns in London, adjust your CPL targets upward accordingly — but also factor in the typically higher treatment fees London practices command.
03 — The Metrics That Actually Matter
CPL Is an Input. These Are the Outputs.
Practices that optimise purely for the lowest CPL almost always end up with the wrong leads — lower-intent, price-sensitive enquiries that don’t show up, don’t convert to treatment, and inflate the real cost of patient acquisition. The correct framework tracks the full funnel — CPL is only the entry point.
| Metric | Definition | UK Benchmark (well-optimised) |
|---|---|---|
| CPL | Total ad spend ÷ leads generated | £35–£500 depending on treatment |
| Show-up rate | % of leads who attend their consultation | 65–85% for quality campaigns |
| Treatment acceptance rate | % of consultations converting to paid treatment | 25–45% for high-value cases |
| CPA (Cost Per Acquisition) | Total spend ÷ booked treatments started (typically 3–5x CPL) | £175–£500 depending on treatment |
| ROI / ROAS | Revenue generated per £1 of ad spend | 300–500% for optimised accounts |
| LTV ratio | Patient lifetime value vs. acquisition cost | Target: LTV of 10x CPA minimum |
Sources: Dominate Dental UK benchmarks; Dentree 2025; Wise Agency aggregated campaign data.
Show-up rate is often where a campaign’s true performance is revealed. A high CPL with an 80% show-up rate is better than a low CPL with a 40% show-up rate. If leads are coming in but not attending consultations, the problem is usually one of two things: lead quality (the targeting is too broad) or front-desk follow-up speed — calls within 5 minutes of enquiry consistently outperform same-day and next-day callback approaches.
04 — The ROI Maths: Why £250 CPL Is a Good Result
Walk through a realistic implant campaign scenario to understand why a CPL that looks high in isolation often represents exceptional value when the full funnel is modelled.
| Monthly ad spend | £3,000 |
| Average CPL (implants) | £250 |
| Leads generated | 12 |
| Show-up rate (75%) | 9 consultations |
| Treatment acceptance (35%) | 3 new implant patients |
| Average treatment value | £2,500 per implant |
| Revenue (month 1) | £7,500 |
| ROI on ad spend (month 1) | 2.5x — before LTV |
| With 5-year patient LTV factored | 5x–8x |
Those three patients don’t disappear after their implant. They return for hygiene appointments, refer family members, consider additional cosmetic work. The 12-month LTV of an implant patient in the UK runs between £4,000 and £8,000 once the full relationship is costed. That makes the £250 CPL look even better — and explains why practices with a clear understanding of their patient LTV are willing to pay more per lead than competitors who are only looking at the first transaction.
The most important shift in dental PPC thinking: stop asking “is my CPL low enough?” and start asking “is my CPL low enough relative to the treatment value and funnel conversion rate?” A £150 CPL for a teeth whitening campaign is poor. A £300 CPL for a full-arch restoration campaign is excellent. The number without context is meaningless.
05 — Why CPL Goes Wrong: Six Reasons Dental Campaigns Overpay for Every Lead
The 2025 WordStream data confirms dentistry has the lowest CTR of any tracked industry. This is primarily a structural and creative problem — not a platform problem. Here are the six most common reasons dental campaigns produce inflated CPLs.
1. No Negative Keyword Management
Campaigns targeting ‘dental implants’ routinely pick up clicks from job seekers (‘dental nurse jobs’), students (‘dental school near me’), and DIY searches (‘how to fix a broken tooth at home’). Without a maintained negative keyword list, a significant slice of budget is wasted on zero-intent traffic.
Add exclusions immediately for: jobs / careers / training / courses / school / salary / free / NHS / cheap / wholesale / equipment / supplies. Review your Search Terms Report weekly for the first month, then fortnightly once campaigns stabilise.
2. Homepage as the Landing Page
Sending all paid traffic to the homepage is one of the most expensive structural errors in dental PPC. A homepage is designed to introduce a practice, not to convert someone actively searching for Invisalign. Dedicated landing pages per treatment consistently improve conversion rates by up to 50%. Google’s Quality Score algorithm rewards relevance too — a treatment-matched landing page lowers CPC directly.
The rule: one campaign, one treatment, one landing page, one CTA.
3. Geographic Targeting That’s Too Broad
Patients drive 5–10 miles for a dentist. Targeting the entire city generates impressions and clicks from people who will never book. Tighter radius targeting combined with location-specific ad copy (‘Invisalign specialists in Hitchin’) reduces irrelevant spend immediately. If you run multiple locations, each needs its own campaign, geo-specific keywords, and a dedicated landing page. Google rewards tight relevance with better Quality Scores and lower CPCs.
4. Generic Ad Copy
“Quality dental care in [City].” “Gentle dentist — book today.” “Family dentistry you can trust.” These are running in a thousand campaigns simultaneously. When every ad looks the same, CTR drops and the auction becomes a pure bidding war.
Specificity wins: treatment outcomes, pricing anchors, finance options, accreditations, turnaround times, consultation offers. The practice that says “Invisalign from £2,995 — free consultation, results in 6 months” will outperform “Straighten your smile today” in both CTR and CPL.
5. Quality Score Below 6
Google’s Quality Score (1–10) measures ad relevance, landing page experience, and expected CTR. Accounts with low Quality Scores pay more per click for worse ad positions. A 4-point Quality Score difference can mean a 2–3x cost multiplier on the same keyword. Any keyword scoring below 6 needs investigation — the root cause is almost always landing page mismatch, irrelevant ad copy, or low historical CTR.
6. Broken or Missing Conversion Tracking
If call conversions and form submissions aren’t tracked accurately, Google’s Smart Bidding algorithms optimise for the wrong signals — or nothing at all. Every dental campaign must track: inbound phone calls via dynamic call tracking numbers, form submission completions, and online booking confirmations.
Without this, CPL reporting is directionally wrong and optimisation is guesswork. Website updates commonly break tracking code without anyone noticing — verify your setup monthly.
06 — Budget Guide: What Should a UK Dental Practice Actually Spend?
Below minimum viable spend, campaigns rarely generate enough conversion data for Google’s algorithms to optimise effectively — producing higher CPLs, slower learning cycles, and wasted budget.
| Practice Type | Monthly Ad Spend | Expected Leads/Month | Focus |
|---|---|---|---|
| Solo / single-site (general) | £600–£1,200 | 15–30 | Check-ups, emergency, routine care |
| Solo / single-site (high-value) | £1,500–£2,500 | 8–20 | Implants, Invisalign, cosmetic |
| Multi-surgery group | £2,500–£5,000 | 40–80 | Mixed treatment portfolio |
| Large group / corporate | £5,000–£15,000+ | 100+ | Full funnel, multi-location |
Figures are ad spend only. Agency management fees are additional — typically £400–£2,000/month depending on account size and scope.
Practices generating £600k–£1.2m annually typically allocate £3,500–£8,000/month total marketing budget (including PPC, SEO, and content). Those scaling implant and Invisalign volumes often sit at 9–10% of target revenue during the growth phase — a figure that reduces as organic rankings mature and referrals compound.
07 — What Good Looks Like: The Well-Optimised Dental Campaign Checklist

- Monthly reporting covers CPL, CPA, show-up rate, and revenue per channel
- Search Terms Report reviewed weekly during month one
08 — Seasonality & Location: When and Where CPL Changes
CPL is not a fixed target — it shifts with competition, seasonality, and geography.
Seasonality
January is the highest-demand period for cosmetic treatments and Invisalign — ‘new year, new smile’ is a genuine search behaviour driver. Higher competition means higher CPCs. Increase budget going into January and expect CPLs to rise 15–25% during peak weeks.
September is the second-highest period for cosmetic enquiries. Back-to-school patterns drive Invisalign and cosmetic interest.
Summer (July–August) sees general dentistry slow but elective cosmetic searches hold reasonably. Emergency searches spike during holiday periods.
December slows significantly outside emergency care — a good time to reduce spend and reallocate budget to January preparation.
Location
| Market | CPC Premium | CPL Range | Notes |
|---|---|---|---|
| Central London | +30–60% | £100–£500+ | Implant CPCs regularly exceed £35. Corporate dental groups drive aggressive bidding. |
| Major cities (Manchester, Birmingham, Leeds) | +10–25% | £70–£350 | Growing corporate dental presence but still manageable. Strong implant and Invisalign demand. |
| Commuter belt / suburbs | Baseline | £50–£250 | Best ROI sweet spot — lower CPCs, strong demographic for cosmetic and high-value treatments. |
| Rural / regional | –15–30% | £35–£180 | Lower competition means lower CPCs. Watch for lower average treatment fees in some markets. |
09 — The Short Answer
A “good” CPL for dental Google Ads in the UK depends almost entirely on what treatment is being advertised and how the full funnel converts. As a working guide:
- General dentistry: under £50 is good. Under £35 is excellent.
- Cosmetic / whitening: under £60 is competitive. Over £100 needs investigation.
- Invisalign: under £150 is good. Under £120 is excellent.
- Dental implants (single): under £220 is good. Under £180 is excellent.
- Full arch / All-on-4: under £350 is good given the treatment value.
Anything 20–30% below these figures indicates a well-optimised account. Anything 30%+ above them warrants a structural audit of keyword targeting, landing pages, and Quality Scores.
The more important discipline is tracking what happens after the lead arrives. Show-up rate, treatment acceptance, and patient LTV determine whether your CPL is actually generating profit — and those metrics will tell you far more about campaign health than the CPL figure alone.
