Endodontic care on El Cajon Boulevard in La Mesa comes from John C. Pawlak, DDS, MS, a member of the American Association of Endodontists practicing at the La Mesa Crossroads complex. The practice's root canal and retreatment caseload draws referrals from La Mesa dentists including Espire Dental, with each case diagnosed under the office's Cone Beam CT imaging system before treatment begins. That Cone Beam computed tomography unit generates three-dimensional images of root anatomy, fracture lines, and periapical pathology invisible on standard two-dimensional radiographs. Holding both a DDS and a Master of Science in endodontics, the La Mesa dentist treats multi-canal molars, calcified canals, and retreatments of prior root canal failures requiring microscopic reentry. Retreatment cases requiring surgical endodontic reentry pair with restorative follow-through, and the practice coordinates post-treatment crown sequencing with Authentic Dental Designs for permanent restoration after root-canal completion. The most technically demanding procedures involve apicoectomy with retrograde MTA fill and microsurgical root-end resection performed under an operating microscope at up to 20x magnification.
