The Problem With Training On the Job in a Dental Practice
Every dental practice owner has said some version of this at some point: "We'll just have Sarah show her the ropes."
It makes sense in the moment. Sarah's been there four years. She knows how things work. The new hire seems capable. How hard can it be?
Pretty hard, as it turns out — and more expensive than most owners realise.
Sarah Didn't Sign Up to Be a Trainer
Here's the thing about Sarah. She's good at her job. She's fast, she knows your systems, your patients like her, and she keeps the day moving. That's exactly why she's the worst person to train your new hire.
Not because she's bad at explaining things. But because every hour Sarah spends training is an hour she's not doing the job you're actually paying her for. If she's a dental assistant, she's not chairside. If she's your receptionist, she's not on the phones. If she's your treatment coordinator, she's not converting treatment plans.
You're essentially billing one staff member's salary to train another. It just doesn't show up that way on paper, so it's easy to ignore.
"Just Watch What I Do" Is Not a Training Program
On-the-job training in most practices follows the same informal pattern: the new person shadows, asks questions when they think it's okay to ask them, tries to absorb as much as possible, and then gets thrown in the deep end when the practice gets busy — which is always sooner than anyone planned.
The problem isn't that this produces bad staff. Sometimes it works fine. The problem is that it's completely inconsistent. What your new hire learns depends entirely on:
- Who they happened to shadow
- What that person remembered to cover
- How busy that week was
- Whether the new hire felt comfortable asking questions
- What assumptions your senior staff didn't even realise they were making
Two people onboarded six months apart at the same practice can end up with entirely different understandings of how things should be done. One learned to handle billing disputes a certain way. The other learned something different. Neither is wrong, exactly — but the inconsistency creates friction, and friction costs you.
The Situations That Matter Most Aren't Covered
On-the-job training is great for the routine stuff. Where to find things. How to log into the software. The flow of a standard appointment.
What it almost never covers — because it can't, by definition — is the hard stuff. The patient who refuses to pay. The emergency walk-in when you're already running 40 minutes behind. The family member who calls demanding information about a patient. The treatment plan presentation that goes sideways.
Your senior staff learned how to handle those situations through years of experience. Probably some uncomfortable trial and error. You can't replicate that by shadowing someone for a fortnight. And you can't wait for your new hire to rack up enough difficult moments to figure it out themselves — not when those moments are happening in front of your patients.
It Creates a Dependency You Can't Scale
If all your institutional knowledge lives in Sarah's head, what happens when Sarah leaves?
This is the part that catches a lot of practice owners off guard. You've invested months of Sarah's time into training a succession of new hires. But because none of that was documented or systematised, the knowledge doesn't accumulate — it just gets handed from person to person, degrading a little each time, like a game of telephone.
When you're running one practice and you've had the same team for years, you might not notice. But if you're growing, opening a second location, dealing with high turnover, or just trying to take a proper holiday without your phone going off, the cracks start to show.
A training system that lives in your platform instead of your best employee's head is one you actually own.
What It Actually Costs
Let's put some rough numbers to it. If your senior dental assistant earns $65,000 a year, that's about $31 an hour. If she spends two weeks meaningfully involved in training a new hire — not full-time, but a few hours a day — you're looking at somewhere between $800 and $1,500 in lost productivity, conservatively. Per hire.
In a practice with any kind of staff turnover, that adds up fast. And that's before you factor in the cost of mistakes made during the learning curve. The appointment that got double-booked. The instrument setup that wasn't right. The patient who didn't come back after a poor first impression.
None of those show up on a training budget line. But they're real costs, and they come directly out of your practice.
There's a Better Way to Think About It
The goal of onboarding isn't to get someone familiar with your practice. It's to get someone productive in your practice — and to do it without grinding your existing team into the ground in the process.
That means separating the "learn the fundamentals" phase from the "learn your specific practice" phase. The fundamentals — patient communication, triage, infection control basics, how to handle a billing dispute — don't need to come from Sarah. They can be taught systematically, consistently, and without pulling your best people off the floor.
What Sarah *should* be teaching is the stuff that's specific to your practice: your preferences, your rhythms, your patients. That's where her knowledge is irreplaceable. Let her focus on that.
The rest? That's what a proper onboarding system is for.
DentaPath is built to take the fundamentals off your team's plate. Staff complete structured daily modules — covering everything from chairside communication to billing disputes — before they need to apply any of it in front of a real patient. See how it works at dentapath.com.au.
