Endodontists are Dentists who have received an additional 2-3 years of advanced training in root canal therapy procedures (residency) after graduating from Dental School. The training is typically 10 years after high school! They perform routine as well as complex root canal procedures, including endodontic surgeries. Endodontists are experienced with diagnosing oral and facial pain and understand the science of healing and regeneration. All Dentists, including your General Dentist, received training in root canal therapy in Dental School. General Dentists often refer patients needing root canal therapy to Endodontists due to complexities and expertise.
