We are technologically advanced and strive to provide warm and professional service. Quality, joy, and safety are our guiding principles. Scroll down to get to know us better.
Our Story
The start of Tannlæknaþjónustan can be traced back to 1990 when the first clinic was founded in Selfoss. Two years later, the clinic in Hella was added, and in 2013, operations began in Reykjavík. Our goal from the beginning has been to provide warm and excellent dental services for clients of all ages.
Services in Three Locations
For many people, it is a big advantage to be able to receive services in more than one place, adapting to different life stages and residential situations. The clinics are interconnected with a powerful computer system, making it easy to receive treatment at more than one clinic—even from the same dentist.
Our Guiding Principles
We live by the principles of Safety, Quality and Joy. For us, this means we want you to feel confident that when you visit us, you are in safe hands, and that you receive top-quality dental care. We enjoy our work and are committed to ensuring that our clients leave satisfied after every visit.
