For root canal treatment in Encinitas, Craig Deagle operates as an endodontist within the Encinitas Smiles Dentistry practice at 415 Santa Fe Drive near Encinitas Community Park. A magna cum laude DMD from Boston University School of Dental Medicine and a chief residency at the University of Virginia anchor a specialty focus on complex pulpal pathology, with endo-perio lesion cases co-managed alongside periodontists including Encinitas Periodontics & Dental Implants. The MMSc credential adds a research-level foundation to clinical endodontic practice, informing evidence-based treatment decisions for calcified canals, resorptive defects, and traumatic pulp exposures. The practice sits on the Santa Fe Drive medical corridor in New Encinitas, serving referred patients from general dental offices across North County San Diego. Referred pain patterns from cervical and TMJ sources that mimic endodontic symptoms require differential diagnosis, and the practice's myofascial assessment protocol may incorporate complementary evaluation at Acupuncture Continuum for concurrent jaw-tension management. Retreatment of previously failed root canals employs operating microscope magnification with ultrasonically activated sodium hypochlorite irrigation and warm vertical condensation obturation for calcified and C-shaped canal morphologies.
