About De Smet Dental Services

With the consistent growth of the organization’s dental practice in recent years, De Smet Dental Services had outgrown their previous space, and now has its own section within De Smet Community Health Center. In August 2013, De Smet Community Health Center and Dental Services opened their doors to their new facility on the Northeast corner of Wilder Pass and Prairie Avenue. De Smet Dental Services offers digital intraoral panoramic x-rays, full family oral health services, including preventative care and restorative dentistry. The clinic is staffed with a full-time dentist and two hygienists.
