About us

Our philosophy: prevention over aftercare

At Cassius Dental, one thing is always at the centre of everything we do: your oral health – for a lifetime. We don’t see ourselves as a “repair shop”, but as a partner by your side, supporting you over the long term – from the very first baby tooth well into old age.

Our goal is to prevent problems before they even arise. That’s why preventive care plays a key role in our practice. With regular check-ups, professional teeth cleanings and clear, easy-to-understand advice, we want to help you keep your natural teeth healthy for as long as possible.

What matters most to us:

  • Early detection instead of treating pain
  • Individual preventive concepts for every age
  • Transparent, easy-to-follow recommendations
  • Time for your questions, so you can make decisions with confidence

Personal care

For children, we create a calm, playful atmosphere – so visiting the dentist feels positive from the very beginning.

Working adults benefit from clear processes, well-structured appointments, and the option to organise many things conveniently online.

We support seniors with care and sensitivity in everything related to tooth preservation, restorations and oral health as we age.

A close-knit team that knows you

We value a warm, familiar approach – within the team and in the way we care for our patients. Many faces will be the same each time you visit: at reception, in the treatment room, or during your dental cleaning.

We welcome you by name and with a smile, and we aim to ensure continuity in your treatment – so you always have familiar people you can rely on. We also take time to truly understand your situation – professionally and personally.

This is what matters to us most: a long-term relationship in which you can feel confident that your oral health is in good hands with us.

Advantages

What to expect at Cassius Dental

Gentle diagnostics with digital X-rays

With our digital X-ray technology, we can capture precise images of your teeth and jaw structures within seconds. Compared to traditional systems, radiation exposure is significantly reduced — while image quality remains excellent. The images are displayed directly on screen and reviewed together with you. This helps you understand your oral health more clearly and makes each step of treatment easy to follow.

More comfort with digital scanning & CEREC

Many patients find traditional impression material unpleasant. With our digital scanner, we can often avoid these impressions entirely: your teeth are captured contact-free in 3D – comfortable, precise and fast.
Using this data, we can create restorations such as crowns or inlays with CEREC in just one appointment in many cases. For you, that means: no temporary restoration for days, fewer visits, and a perfectly fitting, aesthetic result that can be placed immediately.

Evidence-based dentistry through DGZMK membership

Both dentists at Cassius Dental are members of the German Society of Dentistry, Oral and Maxillofacial Medicine (DGZMK). This membership stands for a strong focus on current scientific findings and clinical guidelines. Ongoing training and professional development are a given for us — so we can treat you according to modern standards. For you, this means: well-founded recommendations, transparent decisions and treatment concepts you can truly rely on.
