  • Dr. Charles  Praska, DDS Photo
    Dr. Charles Praska, DDS

    Dr. Praska grew up in a small farming town in North Dakota. He attended North Dakota State University and earned an undergraduate study in zoology. He spent six years at the University of Minnesota completing his dental studies and orthodontic residency. In July 1990, he joined the practice of Dr. Lloyd Truax, and they spent nearly 20 years practicing together.

    Dr. Praska’s orthodontic passion is changing skeletal problems and making room for crowded teeth during growth so patients can be treated on a non-surgical and non-extraction basis. Airway issues are also huge now relating to sleep apnea issues as adults, so early expansion of very narrow maxillaes or upper jaws can be life-changing! The appliances Dr. Praska uses are very specific to our practice and have been honed and developed over the last 25 years. Dr. Praska loves ortho!

Following her bachelor's degree, she immediately made the cross-country move to complete her dental education in Mesa, Arizona at AT Still University of Health Sciences at the Arizona School of Dentistry and Oral Health (ASDOH) where she earned her Doctor of Dental Medicine degree along with a Certificate in Public Health with a Dental Emphasis.

    Dr. Dickovich became interested in dentistry due to her familiarity with healthcare with a mother as a Physician in Prior Lake, as well as spending (her family would argue “too much”) time at dental and oral surgery appointments growing up.

    Ongoing bleeding, knocked out tooth, fractured or chipped tooth or a major infection. At Northwest Dental Group, we understand the panic that can set in during a dental emergency, so we work tirelessly to put your mind at ease.
