Fear of the Dentist: What’s Really Behind It

Fear of the dentist is widespread. Estimates suggest that around 10 million people in Germany suffer from it. Many more at least feel uneasy when thinking about an appointment. Many are ashamed of it. Yet every fear of the dentist has an understandable cause. If you understand where your fear comes from, it becomes easier to find a way to deal with it.

Where does fear of the dentist come from?

Fear of visiting the dentist rarely starts with the dentist themselves. In most cases, it is rooted in earlier experiences that the nervous system has stored as threatening. These memories can still be triggered decades later—by a smell, a sound, or even just the thought of an appointment.

A study by the University of Hong Kong with over 1,000 patients showed that nearly half of those affected by dental anxiety had traumatic experiences with dental treatment in childhood. In another study, 86 percent reported distressing experiences in the dental chair, 70 percent of them during childhood.

These are not isolated cases. They are understandable reactions to real experiences.

The most common causes at a glance

Painful experiences in the past

Pain during a treatment that no one warned you about leaves a mark. Especially if it happens in childhood, it becomes deeply ingrained. The body learns: this situation is dangerous. And it reacts accordingly next time—even if the situation is objectively safe.

The feeling of loss of control

In the dental chair, you lie back with your mouth wide open, unable to speak, with instruments above your face, someone else’s hands or fingers in your mouth, and little ability to control the situation yourself. For many people, this feeling of being at the mercy of the situation is the most stressful part—not the potential pain of treatment itself. Loss of control is one of the most commonly cited causes of severe dental anxiety.

Learned fear from the environment

Fear of the dentist does not always have to be experienced firsthand—it can also be learned. Children who observe parents or caregivers reacting anxiously to dental visits often unconsciously adopt this pattern. Stories from friends, jokes about the dentist, or dramatic portrayals in films and TV reinforce this effect.

Shame and the vicious cycle

Those who haven’t been to the dentist for a long time often develop shame as well. Their teeth may be in poor condition, appointments have been repeatedly postponed, and now the fear of treatment is joined by fear of being judged. This keeps many people from even making a call.

But fear of the dentist is not a weakness. It has a cause—and it deserves to be taken seriously.

What happens in the body during dental anxiety?

When the brain evaluates a situation as threatening, the body activates its classic stress response. Stress hormones like adrenaline and cortisol are released. The heart beats faster, muscles tense up, and breathing becomes shallower.

This is not a sign of being overly sensitive—it is an ancient survival mechanism. The problem: in the dental chair, neither fight nor flight is possible. The stress has no outlet and manifests as tension, trembling, or the urge to cancel the appointment.

Why come early despite the fear?

Those who keep postponing the appointment make the problem worse on two levels. The fear itself increases because avoidance never gives it a chance to change. At the same time, the need for treatment grows. What could have been solved with a minor issue eventually requires a more extensive procedure.

A first appointment does not have to be a treatment appointment. Many practices offer the option to simply talk first: What am I afraid of? What happened in the past? What do I need to feel safe? These conversations help build trust and remove much of the perceived threat.

Every positive experience at the dentist changes what the brain has stored. It doesn’t happen overnight—but it does happen.

What helps with fear of the dentist?

There is no one-size-fits-all solution. What helps depends on the origin and severity of the fear. Some approaches have proven effective:

Talk openly about your fear: Mention your dental anxiety when making the appointment. A good practice will adapt, allow more time, and explain each step in advance.

Agree on a stop signal: A clear hand signal that immediately stops the procedure gives back a sense of control. Just knowing you can pause at any time significantly reduces tension.

Take it step by step: If you haven’t been to the dentist in a long time, you don’t have to do everything at once. Start with a consultation, then a check-up, then small treatments if needed. Every completed step is a success.

Use relaxation techniques: Slow, deep breathing activates the parasympathetic nervous system and reduces the body’s stress response. Inhale for four seconds, hold briefly, exhale for six seconds. This also works in the dental chair.

Seek professional support for severe dental phobia: Cognitive behavioral therapy shows strong results for dental anxiety. A German study with 160 participants found that after an average of five sessions, 70 percent were able to successfully complete dental treatment. Costs are usually covered by statutory health insurance.

Modern treatment methods: Today’s methods usually ensure that little to no pain occurs. If the fear is still too strong, treatments under sedation or even general anesthesia are options.

Summary

Fear of the dentist does not arise out of nowhere. It has causes—often rooted in earlier experiences, frequently from childhood. The feeling of loss of control, unexpected pain, or learned fears from the environment can leave a deep imprint. Understanding this helps you stop feeling ashamed—and start finding a way forward.
