Reducing anxiety in instances of dental phobia – a key concern of our practice
Treatment of Anxious Patients and Patients with Dental Phobia
Since its launch in 2001, our clinic has specialised in treating patients suffering from anxiety. Over the years, we have supported over 2,000 patients with dentist-induced anxiety. Our overarching goal is to reduce the anxiety caused by visiting the dentist in a phased manner. This can happen only by building a sound relationship of trust between patient and dentist. When treatment comes to an end, it is not just the patient’s teeth that should have been restored; the patient’s mental state should also be rendered robust enough for him to be able to approach dental treatment with a perfectly normal mindset, free from anxiety. We know from our wealth of experience with numerous cases that we have handled successfully that this is an achievable goal. By no means do we rely solely on treatment being carried out under general anaesthesia; instead, we consider a variety of interventions and options that have been tried and tested in our clinic over the years.
Dental phobia or the fear of seeking dental care is a widespread phenomenon. Even if the predominant part of the population regularly sees a dentist, between five and ten per cent suffer from such a strong fear of the dental office, that they only attend when the pain becomes too much to bear. This pronounced form of anxiety is known as dentophobia or dental phobia. Symptoms observed during dental treatment are tachycardia (rapid heartbeat), trembling, excessive sweating, choking, nausea, dropping blood pressure, to the point of circulatory collapse.
It may only be a small minority who suffer from this extreme form of anxiety. Nonetheless, according to surveys, almost 70% of the total population report having a distinctive fear of the dental office.
If you are interested in specific topics or if you want to read the chapter in sections, please choose from the following bullet points:
- Traumatising experiences during childhood or adolescence
- Scaring narrations from others, often from own parents
- General fear of pain
- Needle phobia (fear of injections)
- Fear of losing control
- Shame about the condition of the teeth
- Strong gag reflex during dental treatment (e.g. impression taking)
- Generalised phobias, psychosis and anxiety disorders
Frequently, no specific reason for the dental phobia can be established. Then it is the matter of a primordial fear like the fear of spiders (arachnophobia).
Dental fear often has a disastrous effect on both oral and general health. Inflammation and pain in teeth, gums, and jaw can undermine masticatory and digestive functions.Untreated periodontal diseases are considered a significant risk factor for cardiovascular disease and for diabetes.
One’s appearance also suffers and many dental phobia sufferers are ashamed of their poor teeth and the bad breath they cause. The patient’s often already damaged self-confidence takes a further blow. It is more than likely they cannot talk openly about their anxiety, having been laughed at in the past by friends or even the dentist. This creates a vicious circle that just makes the situation worse.
Our strategy against dental phobia is based on the following elements:
- Reduction of psychological stress
- Gentle, painless treatment
- Laughing gas treatment
- Conscious sedation treatment
- Treatment under general anaesthesia
Building a relationship of trust between patient and dentist is crucial to the success of therapy countering dental anxiety. The first step towards establishing contact is often a huge hurdle for the traumatised, anxious patient. The first impression garnered by such a patient upon arriving at the clinic is therefore all the more important. A stress-free, relaxed atmosphere before, during, and after treatment plays an important role here. That includes preventing unnecessary waiting times, a comprehensive and interesting range of reading material in the waiting room, unobtrusive music in a bright, modern surgery, where the typical smell of “dentist” is nowhere to be found.
When treating pronounced dentophobia patients, it makes sense to carry out early counselling in a neutral conference room without the presence of dental equipment, rather than in the surgery itself.
Of course, a gentle, pain-free treatment technique is vital. And so it is that we dispensed with the traditional anaesthetic needle for treating individual teeth (fillings, crowns). Instead, the tooth is anaesthetized using the modern intraligamentary (Peripress) technique. Advantage for the patient:
- No inserting needles into the oral tissue
- Nearly painless administration
- Immediate effect
- Lips, cheeks and tongue remain unanaesthetized
The dental drill sound dreaded by many can be almost completely eliminated by specially shielded headphones playing relaxing music.
These measures alone are not enough to overcome the anxiety that many patients have built up over the years. Despite positive experiences (“it really doesn’t hurt”), the nightmare of a visit to the dentist still holds much of its horror.
Therefore, our dental office has facilities that provide anxiety-free treatment even in more difficult cases.
This 27-year-old man suffered from extreme dental anxiety stemming from traumatic childhood experiences. He had not been able to summon up the courage to visit the dentist for over 10 years.
He was in severe pain when he checked in at our clinic: deep carious lesions had already partially destroyed and disfigured his teeth, also resulting in the patient becoming socially isolated. The complete restorative work that was needed was carried out using nitrous oxide (laughing gas), to which the patient responded very well: the initial fear of the treatment sessions, some of which were lengthy, subsided appreciably. We were even able to carry out the last few procedures without using any nitrous oxide whatsoever.
Today, the patient has completely overcome his dental anxiety and undergoes treatment in our clinic in a perfectly normal manner.
The analgetic (painkilling) and sedative (calming) effect of laughing gas (chemical formula N2O, dinitrogen monoxide, nitrogen oxide) was discovered in the Nineteenth Century. It has since been used million-fold as an anaesthetic. Before introducing routine local anaesthetics, the analgetic effect of laughing gas was in the foreground. Today, its sedative anxiolytic (anxiety reducing) characteristic makes it an excellent tool for treating anxious patients. In the US and many other countries (England, Australia, Scandinavia), over 50% of all dentists regularly use laughing gas. The use of nitrous oxide has experienced a veritable renaissance in recent years in German-speaking countries, and more and more dentists are offering this safe and effective method of treatment.
How does conscious sedation with nitrous oxide work?
A small nasal mask releases a mix of oxygen and laughing gas. The effect begins after just a few breaths: From a feeling of lightness and relaxation, the patient drifts into a comfortable, trance-like state. Constantly addressable and in charge of the senses, the patient feels a desire to close the eyes. Anxiety and tension make way to a relaxed feeling of security. The custom-made headphones dampen the sound of the surgery. Suggestive, relaxing music supports and intensifies the hypnotic effect of the laughing gas. The patient is able to let go and follow pleasant thoughts. Time flies by.
At the same time, sensitivity to pain ebbs away, as does anxiety. Injecting anaesthetic in the mouth, for many patients otherwise a nightmare, is hardly felt any more. The typical feeling of nausea (gag reflex) experienced by many anxious patients (for example during impression taking) and the strong reflex to swallow, which often make treatment more difficult, are forgotten under sedation with nitrous oxide.
The dentist can vary the depth of sedation, adjusting to suit each patient individually. After treatment, the patient breathes pure oxygen for around 5 minutes. The effect of laughing gas is reversed and the patient leaves the dental office alone with a clear head. This ideal controllability gives laughing gas a decisive advantage over other sedation methods (oral or intravenous).

Also ideal for treating children
Parents and dentist alike are faced consistently with the problem of children reluctant to have dental treatment. Many adults, even if they should know better, avoid essential dental appointments because of dental phobia; so how can appealing to a child’s reason be successful?
Laughing gas is an ideal tool in treating anxious children. However, the child must consciously be able to breathe through the nose (upward of six-seven years) and the nasal passage must be free. Furthermore, children treated with nitrous oxide should be reasonable enough to understand the necessity of their dental treatment. Thanks to the strong relaxing and anxiety-reducing effect of nitrous oxide, around 80% of children who would otherwise refuse normal dental treatment, can now be treated. Reducing gag reflex, nausea and the reflex to swallow while keeping complete receptiveness means treatment (for example fillings) can be carried out thoroughly. This is not always possible, especially with non-cooperative children (defensive reactions, persistently closing the mouth.). Often, the reliable laughing gas method can prevent the need for treatment under general anaesthesia.

Risks and side effects
Laughing gas analgesia is an extremely safe method: With millions of recorded applications in the US, where around fifty-percent of all dentists use laughing gas, not one single serious incident has been reported. This method is not recommended, however, for patients with impeded nasal respiration, children under the age of three years or mentally handicapped people who cannot consciously breathe through the nose. In some rare cases, nausea or vomiting may occur as a side effect. Laughing gas is administered in our dental office under pulse oxymetric measuring. With this method, a finger sensor constantly measures the patients pulse and arterial oxygen saturation, as an extra safety precaution.
FAQs on Nitrous Oxide
Sedation is the term given to a state of immobilisation or semi-consciousness brought about by medication (sedatives). Today, many medical examinations and procedures are carried out under sedation; these include gastroscopy and colonoscopy. Sedation is playing an increasingly important role in dentistry, too. There are a number of medicines that have a markedly calming (sedating) effect when administered intravenously as an injection, or orally, for instance in the form of tablets or drops. Today, these are primarily active ingredients from the so-called benzodiazepine group.
With these drugs, depending on the dose, a sedation can be achieved ranging from mild relaxation to a deep twilight sleep. A welcome side effect is that normally patients have little memory of the procedure after it is over. For the most part, even the gag reflex that proves problematic in some patients (e.g. when obtaining a mould impression) disappears completely under sedation.
Controlling the dosage of these sedatives requires special experience as the individual dosage can vary tremendously. The dosage needed to put some patients into a relaxed state can be enough to anaesthetize others. Unlike the conscious sedation with nitrous oxide, the sedative effect usually lasts longer than the treatment itself. The patient is not able to leave the dental office alone, and always needs the help of a companion.
The use of sedative medication in our dental office is restricted to surgical interventions as well as anxious patients for whom laughing gas is not effective enough.
Once treatment is complete, we provide after-care to our sedated patients in our recovery room, where they can rest in comfort.
FAQs on Twilight Sedation
Particularly when major interventions or restorative procedures are indicated, many patients prefer not to be conscious during treatment. We can cater to this by carrying out treatment under general anaesthesia. We carry out treatment under general anaesthesia several times a week as a matter of course in our state-of-the-art operating theatre and recovery room. We are supported in our work by experienced narkose.ch anaesthetists, with whom we have been working successfully for over 15 years. General anaesthesia administered by an anaesthetist is now considered to be extremely safe, and complications are very rare.
We consider procedures carried out under general anaesthesia to be primarily indicated in the following:
- Major surgical and implant procedures
- Treatment of anxious patients who do not respond well to nitrous oxide or sedation or who express a preference for general anaesthesia
- Treatment of anxious and uncooperative children
FAQs on General Anaesthesia
Ms Esther Burckhardt, Thun:
Our 67-year-old patient Ms Esther Burckhardt from Thun relates her experience: “I suffered from advanced periodontitis and could barely eat any more with my teeth being so weak. As a result of the inflammation, I had chronic pain and had to regularly take strong painkillers. I have suffered dentist-induced panic attacks since I was a child. This is why I have always put off thinking about implants. Because my teeth were so appallingly bad, in the end I stopped socialising altogether and felt increasingly isolated and depressed. When my daughter told me about the All-On-Four method, I had a glimmer of hope. Fixed teeth in one day: until now, this had just been a pipe dream. One day, I got my act together and decided to undergo a complete restoration procedure under general anaesthesia. Not for an instant have I regretted my decision to resolve my dental issues once and for all. My attitude towards life has changed completely now that my teeth are so strong and attractive; I feel much younger and more self-assured. And I can eat what I want once again without any worries. He who laughs last laughs best!”.
The 2,000+ anxious patients treated in our clinic were asked to respond to a survey before, during and after treatment; we have used the results of this survey to compile statistics that allow us to review the success of our strategy to counter dental anxiety. This reveals that 74% of the patients treated experienced a significant decline in their original dental anxiety and 12% a perceptible decline. In just 14% of those surveyed was there absolutely no change. These data assure us that we are on the right path with our strategy to reduce dental anxiety.
