Dr Williams has a referral practice dedicated to endodontics (root canal treatments) and is a lecturer and opinion leader (OPL) for a leading Swiss Endodontic company, FKG Dentaire. His passion for endodontics stems not only from a bad personal experience but also the lack of faith the general public and even his own colleagues have in successful endodontic outcomes.

He practices biologic endodontics incorporating an armamentarium of cone beam computed topography (CBCT/3D radiography), Dental operating microscope (DOM), three- dimensional instrumentation and irrigation.

He believes the game changer in his last 10 thousand cases has been the use of a biologic, bioactive and bone regenerative sealer viz Calcium Silicate phosphate.

All patients are monitored at 6 monthly intervals at no extra fee so as to monitor his prognostic success
