Our fun and friendly team is dedicated to caring for you and your entire family’s orthodontic needs and well-being. At your first visit to our office, Dr. Polgrean will complete a no obligation orthodontic examination, evaluating many things relating to your face, your smile, the fit of your teeth and the amount of room for all your teeth. During your complimentary consultation appointment, Dr. Polgrean will give you her professional recommendations regarding your orthodontic care. From this initial visit, if you are ready for treatment, you will be given a personalized treatment plan, information on which treatment options are available, when your treatment would start, and an estimated treatment time.
