What Colosseum Tannlege does

Colosseum Tannlege is Norway's largest dental clinic chain, operating 30+ owned clinics spanning from Tromsø in the north to Kristiansand in the south and serving over 700,000 patient visits annually. The company is headquartered in Oslo and employs 501-1,000 staff. It was founded in 1986 and operates as a private, for-profit entity, growing primarily via tuck-in acquisitions of established independent dental practices that join the network while retaining their local presence.

The company delivers a comprehensive dental service portfolio across preventive, general, cosmetic, and specialist dentistry. Offerings include annual check-ups (Tannsjekk), professional cleaning (Tannrens), orthodontics (traditional braces and Invisalign), dental implants, oral surgery (including wisdom teeth and cyst removal), endodontics (root canals), periodontics, prosthetics (crowns, bridges, dentures), cosmetic services (whitening, veneers), and sedation/general anesthesia. Underlying technology includes CBCT 3D imaging (deployed across more than 15 clinics), OPG panoramic X-ray, intraoral 3Shape digital scanning, AirFlow cleaning, and laser-assisted treatment. A specialist sub-brand, SpesDent Spesialistklinikk, provides maxillofacial surgery, periodontics, endodontics, prosthodontics, and radiology, while a mobile home-visit service ("Tannlegen Hjem") extends reach to elderly, disabled, dementia and dental-anxiety patients in the Gjesdal area. Advanced training is delivered through the Colosseum Academy in Oslo, described as one of Northern Europe's premier dental training facilities.

The revenue model is predominantly fee-for-service (transaction-based), with prices varying by clinic and treatment. Public pricing is not uniformly disclosed. Distribution is direct-to-consumer via owned clinics, supported by online booking (minside.colosseumtannlege.no), a central customer service line, public-dental-service referrals for orthodontic cases, general-dentist referrals for specialist services (digitally via Boneprox), and corporate/business agreements for employer groups. Helfo subsidies are leveraged for qualifying treatments (orthodontics for children/youth and selected specialist procedures). Patients span general consumers, cancer patients, those with dental anxiety (odontofobi), and orthodontic patients across all ages, with student discounts offered at select clinics.
