The 10 Qualities of a Good Teacher (in Dentistry)

Through my years of training and clinical practice I was lucky enough to meet teachers who left an indelible mark on my professional path. Reflecting on what made them so special, I identified a handful of fundamental traits that separate a true master from someone who merely transmits notions.

Deep Competence: Knowing in Order to Teach

The first non-negotiable quality is a thorough command of the subject. A good teacher must master their discipline at least ten times better than their most prepared colleagues. That extended competence lets them carry few doubts — never zero, because the total absence of uncertainty breeds arrogance, the enemy of effective teaching.

Knowledge must be broad enough to give exhaustive answers to students’ questions. And yet one of the best teachers I ever had, Professor Jan Lindhe, taught me the value of a sincere “I don’t know”.

That answer, spoken without hesitation, carried a deep message:

even masters are human beings, and knowing that you don’t know is a sign of intelligence and intellectual curiosity.

After all, Socrates already told his pupil Plato that he “knew that he knew nothing”.

A Passion for Passing It On

Competence is not enough; you need a real desire to teach and to hand knowledge over. A professor “parked” in a chair for connections rather than merit, who simply “warms the seat” to collect a salary, will rarely become an effective educator. Teaching demands intrinsic motivation, a push that comes from somewhere deeper. It is the same push that turns a technique into a method worth handing to others: the Bonebenders method was born exactly that way — from the need to make teachable what one has learned.

Practical Skill: Hands That Teach

In medicine and dentistry, the best teachers are the ones who “can do something with their hands”. That practical competence is passed on through direct demonstration, by physically guiding the student’s hands, or by letting them “steal with their eyes” — watching every gesture closely.

This is not just rhetoric. The meta-analysis by Görücü and colleagues (Nurse Education Today, 2024), pooling fourteen controlled studies, shows that repeated practice on a simulator measurably improves the ability to decide in front of the patient — not the mere recall of facts, but clinical judgement. The hand that repeats learns to think. It is the reason certain techniques, such as graftless ridge expansion, are taught beside the chair and not in front of a blackboard.

Contagious Enthusiasm

Good teachers know how to inspire because they themselves feel a strong love for what they do. They believe deeply in their work and know they can make a difference. That authentic passion becomes contagious, spreading to students naturally, with no need for tricks or “special effects”.

Authenticity: No Show, Just Substance

A true master needs no spectacle to capture attention. The “special effects” live inside them and inside the things they do, which become engaging on their own. Authenticity is more powerful than any didactic marketing strategy.

It is worth saying right now, while virtual reality enters the classroom. The meta-analysis by Bevizová and colleagues (BMC Medical Education, 2024) compared VR with traditional teaching in dental anatomy: the effect is moderately positive before clinical experience, but — and I quote — virtual reality “falls short compared to clinical experience, training with physical teeth, or quality printed models”. The screen helps you warm up. It does not replace substance. Which is exactly what a good teacher knows by instinct: the shiny tool is never worth the real gesture.

Human Closeness

While keeping their role as a guide, the best teachers shorten the distance with those who want to learn. They consider students more as brothers than as mere pupils, building a learning environment based on mutual respect and sharing. Sometimes the shortest distance is the one between father and son, between one generation and the next: it is from that passing of hands that certain ideas keep living.

A Constructive Approach to Mistakes

A good teacher does not “crucify” students for their mistakes, knowing full well that we learn precisely by getting things wrong. They always have a word of comfort for whoever errs, but they also know how to steer toward more suitable paths when certain mistakes repeat too often.

There is a striking convergence in the data on how a mistake gets corrected. The Cochrane review by Ivers and colleagues (2025), which brought together 292 studies, shows that feedback truly changes clinical practice — but only under certain conditions: it must measure the individual, not the group; it must come from someone with whom a relationship exists; it must point to a concrete action, not a grade. Translated: a mistake is corrected within the relationship, not within the reproach. And when you work on error in a structured way — debriefing — the review by Duff and colleagues (Simulation in Healthcare, 2024) warns that even the most widespread techniques rest on still-fragile evidence. Which means the “how” is dictated largely by sensitivity and by the alliance with the learner, more than by any protocol.

Professional Ethics

It is essential to keep the utmost fairness in interpersonal relationships, respecting professional and ethical boundaries. The teaching relationship must stay pure and focused on learning.

Students at the Center: The Real Protagonists

The best teachers know they are not the protagonists. They recognize that real success lies in making protagonists of those who give them their attention and time — the most precious thing they own.

The Final Lesson: Always Stay a Student

Finally, a trait I consider fundamental:

a good teacher will always also be a student.

Curiosity, the desire to learn, the humility to admit there is always something new to discover — these are the traits that keep the love of teaching alive and make it authentic.

And one last thought:

Good teachers have no ius primae noctis over their students’ partners (because this, too, has happened!).

These reflections come from direct experience with masters who knew how to leave an indelible imprint on my training. I hope they can be useful to anyone in the role of educator, remembering that to teach is, before anything else, an act of love toward knowledge and toward those who wish to grow.
