Meet our Team

Dr. Zack Goettsche, DDS
Endodontist + Owner

I am a Board-Certified Endodontist and the founder of Northern Plains Endodontics in Sioux Falls, South Dakota. After earning my dental degree from the University of Iowa College of Dentistry, I completed my advanced specialty training in endodontics and served as adjunct faculty at the University of Iowa while caring for patients in private practice.

In 2021, my wife, Lainee, and I relocated to Sioux Falls to establish Northern Plains Endodontics with a vision of providing exceptional patient-centered specialty dental care to the community. We fell in love with Sioux Falls, putting down lasting roots in the area, now raising our two young sons, Hugh and Simon.

My philosophy centers on compassionate, diagnosis-driven care and clear communication with every patient. From the first consultation to the completion of treatment, I prioritize education, transparency, and comfort every step of the way. At Northern Plains Endodontics, we have intentionally created a calming and welcoming environment designed to ease dental anxiety, with thoughtful touches such as soothing music, dim lighting, and a relaxed atmosphere so patients feel comfortable from the moment they walk through the door.

To my colleagues, my goal is to make referring to us the easiest part of your week. We get your patient in quickly, with same-week appointments typical and same-day for emergencies. You will stay updated with same-day reports and a phone call directly from me if I have any questions about how you would like to proceed. Your patient comes back to you completely satisfied with the experience they received.

Outside the office, I enjoy cooking (often with mixed reviews from the family), running, pheasant hunting, trout fishing, and of course the best times are enjoying family time with Lainee and the boys.

Technology

Advanced Technology

EdgePro Irrigation Device

New advances in fluid dynamics and laser energy have resulted in devices which are better able to clean and disinfect the root canal system. Our office is committed to utilizing the newest and most advanced technologies available which provide better outcomes and help preserve the natural tooth structure.

CBCT

Cone Beam Computed Tomography (CBCT) is a game changer in endodontics. This device allows our office to acquire a 3D X-ray of the area we are treating to better diagnose and treat the condition. Armed with the knowledge of what, where, and why the problem exists, we can accurately and conservatively fix the problem with fewer X-rays and a more predictable outcome.

Dental Operating Microscopes

Microscopes are crucial to identifying and treating the root canal system. They provide a level of precision during treatment that helps save natural tooth structure. Each microscope is equipped with LED illuminators and has up to 19x magnification. A high-definition camera is attached which allows for photo and video capture to better educate our patients and communicate with our referring dentists.

Ultrasonic Instrumentation

Conserving natural tooth structure is key to a successful root canal treatment. Ultrasonic instruments allow for precise removal of tooth structure only where necessary to clean the root canal system. These instruments vibrate over 30,000 times per second to gently smooth and polish inside the tooth.

Bioceramic Materials

Material selection is important to ensure that the body is allowed to heal and returns to a normally functioning state. Bioceramic materials are designed to mimic natural tissues within the body to allow for a healthy interface between the body and the root canal system.

Sedation

Dental anxiety is a common condition which can create a steep barrier to dental care. We specialize in alleviating anxiety and providing a relaxing and calming appointment. Our office offers oral sedation and nitrous oxide to patients who need a little extra help feeling comfortable. If you are interested, be sure to ask about this option when scheduling your appointment.

Sterilization

Patient safety is of the upmost importance in our office. We utilize the most stringent sterilization protocols to properly clean and disinfect all dental equipment. In addition, our staff is trained and follows all OSHA and CDC recommendations to prevent the spread of COVID-19.
