Allen Wei, DDS operates a dedicated endodontics practice on Lake Murray Boulevard in La Mesa, specializing exclusively in root canal therapy, endodontic retreatment, and dental trauma management near the Lake Murray residential corridor. General dentists across East County refer complex molar and multi-canal cases to this Lake Murray office, including practices such as Espire Dental whose patients return for crown fabrication after endodontic clearance. The practice specializes in treating teeth with tangled, calcified, or previously failed root canal anatomy, using magnification-assisted instrumentation to locate and debride accessory canals that conventional treatment may miss. A conservative diagnostic approach emphasizes tooth preservation over extraction, with cone-beam imaging guiding treatment decisions for cracked-root differentials and periapical pathology assessment. Post-endodontic restorative coordination returns patients to their referring general dentist for permanent crown placement, a workflow that cycles through La Mesa practices including Authentic Dental Designs on the East County referral network. Highest-complexity cases involve retreatment of previously instrumented canals with separated file fragments, apicoectomy with retrograde MTA fill for persistent periapical lesions, and emergency stabilization of avulsed permanent teeth requiring splinting and pulp vitality monitoring over sequential follow-up visits.
