About Dr. Keith D. Sonntag, DDS

Endodontics occupies a specialized niche within dental care, addressing issues that extend beyond routine cleanings or fillings. When root canals, traumatic dental injuries, or complex pulp infections arise, patients often seek out practitioners who focus exclusively on these procedures. Dr. Keith D. Sonntag, DDS operates within this field, offering targeted treatments that include root canal therapy, endodontic retreatment, and the management of dental trauma. The practice is situated at 1345 E 3900 S Suite #112 in Salt Lake City—a stretch of the city where medical offices and quiet residential blocks intersect. Unlike general dentistry, endodontic work demands precision tools and techniques designed to preserve natural teeth; this distinction shapes both the patient experience and the scope of care provided.

Salt Lake’s east-side corridors host a mix of healthcare providers, and this endodontic office fits neatly into that professional landscape. Questions about treatment options or scheduling are handled directly; patients can reach the office at (801) 274-6900 for details. While the nature of endodontic work might not require frequent visits, the procedures themselves—like apical surgeries or diagnosing cracked teeth—often serve as critical interventions. For those mapping out their route, the office’s location is pinned here; it’s a straightforward stop in a neighborhood where practicality tends to outweigh flash.
