We want all our patients to be informed decision makers and fully understand any health issues you may face. This website is loaded with information about periodontal disease, dental implants, periodontal treatment and as well as links to related topics.

Feel free to browse any of our menu options for more about our periodontists, staff, office hours, appointment procedures, forms, maps, directions to our offices and other useful information.

We invite you to email or call our offices at any time to request an appointment or ask any questions. Our offices are located in Sioux Falls and Aberdeen.

At Midwest Periodontics, we only treat periodontal disease and related disorders. It’s what we’ve been doing for more than 25 years. That has allowed us to develop enormous experience and knowledge in our field. As a patient, that means you are being treated by the specialists and staff who can best help you through your periodontal treatment.

As periodontal specialists, Dr. Kassube and Dr. Paul Johnson have received advanced training in dentistry, medicine, surgery, microbiology, and soft and hard tissue (gum and jawbone) physiology. In addition, they continually update their knowledge and techniques through a commitment to continuing education. By seeking the care of a specialist, you are ensuring that you receive the highest standards of treatment in the field of periodontology.

In addition to highly specialized doctors, the practice is proud of the expertise and training of our hygienists and dental assistants.

While expert technical treatment is a hallmark of Midwest Periodontics, we also focus on providing that human touch that means so much to our patients. Whether it’s the smiling face at the reception desk, the hygienist who assists you in maintenance of your teeth and gums, or the doctor who consults and completes your periodontal work, everyone at Midwest Periodontics is committed to providing you with quality care.
