Deep Dive: Root Cause (2019)
Film Lens

Root Cause is a documentary film produced by Frazer Bailey that examines the filmmaker's belief that his chronic fatigue and anxiety stem from root canal treatments. The film chronicles a decade-long search for answers, beginning with conventional medicine and moving through various alternative therapies, ultimately concluding that his previous root canals are the culprits behind his health issues.
The film makes controversial claims linking root canal therapies to serious illnesses, including cancer, and suggests that extracting infected teeth is a safer alternative. It asserts that 97% of breast cancer patients had a root canal on the same side as their cancer and that root canals are a leading cause of heart attacks, claims that have been widely criticized and dismissed by dental professionals and organizations as false and misleading.
