Dr Sonja Britz qualified as a dentist from the University of Pretoria in 2005 and completed her community service the following year. In 2007, she started working in a private group practice in Pretoria. Endodontics and oral surgery are two subjects in dentistry that really appeal to her which she has focused on throughout her career thus far.

Assisting in theatre on a weekly basis since working in private practice encouraged her to complete a postgraduate diploma in oral surgery in 2012, during that time also doing session work at the University. In 2015 and 2016 she completed a 14-month basic implantology and soft tissue augmentation course, relocated to Cape Town, and became a member of the international team for implantology. She drives herself to save a tooth above replacing it with an alternative, which prompted her to recently complete her diploma in endodontics through the University of Pretoria.

As a Microscopic Endodontic Dentist, Dr. Sonja Britz aims to save teeth and restore them.
