Björn graduated as a dentist from Erlangen-Nuremberg University, Germany, in 1997. After working  in a research group dealing with the causes of gum disease, he obtained a doctorate in periodontology in 2001. Since he gained his first work experience in a maxillofacial hospital department, his main interests have been in oral surgery and implants while he was working in a private practice in Germany.

Just as his mum years before him, Björn moved to the UK, initially for 2 years, to study. In 2005, he completed the Step-Wise-Dental Implant Course at Cardiff Dental School. Björn deepened his special interest in root canal treatments by gaining a Certificate in Advanced Endodontics from the Endoplus Academy in Cologne in 2008.

Björn’s interests also include orthodontics. He is a provider of Fastbraces® Technology and clear aligners, and he applies his knowledge in aesthetically demanding cases involving both orthodontic and restorative treatment while creating a relaxing atmosphere for his patients. Björn accepts referrals for root canal treatments, aesthetic dental treatments, complex prosthodontic treatments, and orthodontic treatments.
