Endodontist Horst Dziura DDS in Carlsbad Village performs root canal therapy at Carlsbad Village Faire Dentists and Orthodontics, Suite 203 at 300 Carlsbad Village Drive inside the Carlsbad Village Faire Shopping Center. A Northwestern University Dental School graduate with a University of Notre Dame undergraduate degree, the endodontist has practiced since 2003, holds California Dental Board license 47253, and provides services in both English and Spanish for the Village's diverse patient base, including referrals from optometric providers such as Carlsbad Optometry when dental-origin pain mimics ocular or sinus symptoms. Operating within the Smile Generation and Pacific Dental Services network, the endodontist receives internal referrals from the group's general dentists for single-visit and multi-visit root canal therapy across the practice's multi-specialty caseload. The endodontic scope covers vital and necrotic pulp extirpation, retreatment of previously treated canals with persistent periapical pathology, and post-and-core buildup preparation for final crown restoration by the referring general dentist. Medically complex patients on anticoagulant therapy or bisphosphonate medication requiring endodontic treatment coordinate clearance through integrative medicine providers such as Quantum Functional Medicine to manage systemic risk factors before pulp extirpation. Molar root canals are instrumented with rotary nickel-titanium file systems using electronic apex locators for working-length determination, followed by warm vertical condensation obturation with gutta-percha and bioceramic sealer for hermetic apical seal.
