Around 60-80% of Austrians feel nervous at the dentist, 10-15% suffer from severe dental phobia. These fears are often caused by childhood experiences or negative experiences. The good news is that dental anxiety is widespread, but can be overcome with the right dental team and treatment options tailored to your individual needs.
Dental anxiety doesn't just manifest itself in the mind, but in the whole body. Many anxious patients experience palpitations, trembling, sweating or nausea days before their dental appointment. These physical symptoms are an expression of a deep-rooted stress reaction that has arisen in many patients as a result of traumatic treatment in childhood.
Transparency creates trust. Find out what you can expect from your dental treatment and how we respond to your individual needs.
No, absolutely not. The initial consultation at our dental practice in Vienna is exclusively for the purpose of getting to know each other and building trust. We take the time to take a detailed medical history, discuss your fears and draw up a treatment plan together. You decide when you are ready for the first procedure.
Yes, you are welcome to bring someone you trust with you, as this gives many anxious patients additional security. Your companion can stay by your side during the entire appointment. Emotional support is particularly valuable during the initial consultation and for major procedures under sedation or anesthesia.
We stop the treatment immediately and take care of you. Our team is trained in dealing with panic attacks.
You can:
Then: take a deep breath, drink water, calm down. We will only continue if you want us to.
This depends on the anesthetic procedure. After twilight sleep or general anesthesia, you will need about 2-4 hours to recover. You are not allowed to drive yourself afterwards, an accompanying person should take you home.

For extensive procedures or severe dental phobia, we offer treatments under general anesthesia with experienced anesthetists. You will sleep deeply and pain-free and wake up with healthy teeth.

This prescription sedative noticeably reduces nervousness and dental anxiety. You take it one hour before your treatment and should therefore arrive at our practice one hour early.

Not everyone needs sedation. Through honest discussions, transparency and a step-by-step approach, we help many patients to overcome their fear of the dentist without medication.

Whether you are slightly nervous or have had a dental phobia for decades, we will meet you where you are. Our treatment of anxiety patients specializes in individual solutions for every type of anxiety.
The better you know your fear, the easier it is to treat. We explain the different stages of dental phobia.
You feel a little uneasy before your dental appointment, but a visit to the dentist is manageable. Slight nervousness is completely normal and affects most people. A calm conversation, transparent explanations and a pleasant atmosphere are often enough to put you at ease. Together we can create a stress-free process.
Your anxiety is stronger: you put off appointments, brood days in advance and experience physical symptoms such as a racing heart. Gentle methods such as sedative drops or conversation-based anxiety management can help here. You remain conscious but feel much more relaxed during your dental treatment.
Have you been avoiding visits to the dentist for years, even when you have toothache? This is dental phobia, a serious anxiety disorder. Traumatic experiences are often the cause. We offer treatment under general anesthesia so that you can find your way back to healthy teeth and avoid tooth loss.
You will notice the difference as soon as you enter. Coffee house atmosphere, warm colors and an empathetic team. You can arrive here.
Quieter devices, gentler methods and a TV on the ceiling. So you can lean back in complete relaxation and enjoy a video of your choice.
No one is passed through here. We listen, take our time and adapt every step to you. Your pace counts.
Sometimes talking helps more than medicine. We explain everything to you beforehand, answer every question and only go further when you are ready.
Our team will treat you with understanding and patience. We know your concerns and take time to answer your questions.
Each treatment is divided into small, manageable steps. This means you remain in control and can pause at any time.
Make an appointment for your non-binding initial consultation, without any obligation to undergo treatment. Get to know our team and find out how we can help you. We look forward to meeting you.

If you don't like going to the dentist, I can only recommend this one - clean work, completely pain-free, and most importantly - the patient is cared for during the treatment instead of just drilling away. I don't know how he does it, but it works.

Dr. Quidenus and his team take the time to explain the treatment in detail, and my treatments were always pain-free - all in all, the most pleasant dentist I've ever been to!
Melina Neurath
Teeth are a delicate and sensitive subject - so it's all the more important to be in good hands. I felt well looked after, advised and looked after all round.Dr. Quidenus and his team were competent, friendly and empathetic. I can highly recommend them!
Markus Leich
I have received numerous implants and crowns from Dr. Quidenus and I am very satisfied! There is a wonderful atmosphere in the practice with a great team!!!
Sofia Haspel
Highly recommended for anxiety patients!You can't help but be impressed by both his extraordinarily easy-going manner and his skills! He can do so much more than many other dentists and you feel that you are in very good hands with him. He takes time for his patients and makes you feel that you are in good hands (which you are).
Crissy Koch
Dr. Quidenus is competent and friendly. He has new machines and I think that makes a big difference. I didn't have anything serious, just fillings, but I still felt very comfortable in the practice. The whole team is extremely nice and helpful.

The cost of dental treatment under general anesthesia or sedation varies depending on the extent of the procedure and the sedation method chosen. At our dental practice, we will advise you transparently about all the costs involved before you make your decision.
However, sedation procedures such as nitrous oxide, twilight sleep or general anesthesia for dental anxiety are usually considered private services and are not covered by statutory health insurance. There are exceptions in cases of medical necessity – talk to us and we will help you clarify the situation.
We know: High-quality treatments for anxiety patients can be cost-intensive. That’s why we offer flexible financing options and installment payments. So you can restore your dental health without overburdening yourself financially. Give us a call. We will discuss together which solution is right for you and provide you with a non-binding cost estimate.
Getting to know you is all about you: we listen, understand your fears and discuss what will help you. No examination, no drill, just an open discussion about your needs and wishes.
We only start the examination when you are ready. We explain every step, work with hand signals and take breaks whenever you need them. An X-ray helps us to determine the need for treatment.
Whether with nitrous oxide, twilight sleep or general anesthesia: you decide which sedation feels right for you. We are there for you throughout the procedure and monitor your well-being.
Treatment is just the beginning. We support you in the long term with regular check-ups, professional teeth cleaning and further anxiety management so that you remain anxiety-free.
Dr. Andreas Quidenus knows from over 20 years of practical experience: dental anxiety is real, and it deserves respect, not lectures. That’s why he has specialized specifically in treating anxious patients, with one clear goal: to make you feel more confident every time you visit the dentist than the last.
“I meet every anxious patient where they are. Some just need a calm conversation, others general anesthesia. Both are fine. What’s important to me is that you can laugh again without any pain or shame.”
