Case Study — Radent Dental Clinic
"The Leads Are Shit." Every clinic running Meta ads has said it. Here's proof they're wrong.
The leads aren't shit. Manual follow-up, done by humans, is the problem.
Here's how we fixed it — with evidence from 1,567 real calls.

“In the first 10 days, Anna booked 13–14 consultations — nearly double what our receptionist managed in the same period. Three patients had already come in. What really surprised us was that many of these were patients our receptionist couldn't convert. She simply couldn't handle the volume. If the AI keeps improving, it changes everything.”

See exactly where your money leaks
Evenings, weekends, Monday mornings before you open. This report shows you who's catching them for you.
What happens when every lead gets a callback in seconds

8 min read · Worth it if you spend money on Meta ads.
Is this report for you?
- ✓ You spend €1,000+/month on Meta ads (Facebook or Instagram)
- ✓ Your receptionist says "the leads are garbage"
- ✓ Your cost per booking is climbing, but the calendar stays empty
- ✓ You know leads are coming in — you just suspect most get lost before anyone calls them back
01 — Symptoms
The Monday Morning Problem
You open your laptop Monday morning. Forty-seven new leads from the weekend are sitting in your CRM. You don't feel excited when you see them.
Your stomach tightens.
Because you know what comes next.
The receptionist drops everything and starts dialing strangers. The first three don't pick up. The fourth says "What? I never asked for anything." The fifth hangs up. The sixth wants the price, hears the number, and disappears.
By lead fifteen, she's not qualifying anyone. She's surviving. She's been rejected nine times before lunch and she's mentally checked out.
And those forty-seven leads? By Wednesday they're cold. By Friday, they've already called your competitor — the one who picked up first.
You can't tell which of those 47 leads was ready to spend €5,000 on implants. They all looked the same in the spreadsheet. And your team treated them all the same — which means the €5,000 patient got the same rushed, annoyed, three-rings-and-voicemail treatment as the one who clicked by accident.

02 — Diagnosis
Follow-Up Failure Syndrome
The disease isn't in your ads.
It's in the gap between form submission and the first call.
of Facebook leads never answer the first call
Not because they're bad leads. Because they filled out the form at 11 PM in bed on their phone, and your team called at 10 AM the next day. By then, they've forgotten.
of all inbound calls to the clinic go unanswered
Not because the receptionist is lazy — because she's already on another call. That patient doesn't leave a voicemail. They Google the next clinic.
If your receptionist seems like she's given up, it's probably not laziness — it's from calling strangers who don't want to talk. Sound familiar? Then she starts telling you the leads are garbage. Stops calling after the first attempt. Cost per acquisition climbs. And you start wondering if Facebook ads even work.
Clinical Assessment
The problem is that you're asking a human to do a machine's job — dial 1,256 numbers, absorb 768 no-answers, endure 68 rejections — and still have empathy left for the ones who actually want to come in.

Without AI, this €3,000–5,000 patient calls your competitor Monday morning.

Transcripts from the Field
Patient
"I've lost several teeth. I can't eat. Another doctor said nothing can be done. I'm devastated."
Agent
"I understand, that's discouraging. We frequently treat cases that other clinics have turned away. A free evaluation with the Doctor will determine exactly what can be done."
Patient
"I'd like that, but I'm really afraid of being rejected again."
Agent
"It's completely normal to feel that way, especially after being turned away..."
Evaluation booked — Friday, 4:45 PM. Turned fear of rejection into a confirmed appointment.
Patient
"It's a lot. I can't afford it."
Agent
"You're not the only one with that concern. We can do the free evaluation so you have a clear picture — no obligation. Would you book, even just informally?"
Patient
"Let's book it."
This is the patient your team would have marked as "not interested."
Patient
"I'm not from your city. I can't get there."
Agent
"For patients from other cities, we offer a €150 travel bonus per arch, covering transport and accommodation."
No pre-programmed script could have done this — dynamic knowledge base extraction based on the caller's context.
Patient
"I had 5 implants placed last week, terrible pain, very swollen..."
Agent
"I understand this is urgent. I'm transferring you immediately. Please stay on the line."

07 — Financial Impact
Revenue at Risk
Here's what happens to a typical €2,000/month Meta ad budget without instant follow-up:
With Tellet AI
1,256 leads → 628 conversations → 25 bookings in 21 days
At 20% conversion rate:
€15,000–25,000 recovered revenue
Same leads. Same budget. Same campaign. Different operator.
How many €5,000 patients did you lose this month
because nobody called them fast enough?
08 — Common Objections
Answered
"Patients will know it's a robot and hang up."
272 people called KNOWING it's AI. 126 became real conversations. People don't care if it's AI — they care that someone picks up.
"Healthcare needs a human touch."
Agreed. The AI booked 25 AND transferred 14 complex cases to humans. Your team handles 14. The AI handles the other 1,553.
"We already have a receptionist."
Perfect. Stop making her cold-call strangers from Facebook. Let her do what she's actually good at. Let the AI do the part she hates.
"Facebook leads are low quality."
The AI found 25 ready patients in 1,256 leads. They weren't low quality. They were unfiltered. Now they're filtered.
