Demko Orthodontics in St. Charles, MO, specializes in orthodontics, early orthodontic treatment, and airway-focused orthodontics. Dr. Jacqueline Demko, DDS, MS, is a fourth-generation orthodontist who takes a modern approach to orthodontics. Dr. Demko's goal is to improve facial harmony and symmetry while maintaining or creating a healthy airway, in addition to straightening teeth. By using orthodontic expanders, Dr. Demko can help patients avoid orthognathic surgery and tooth extractions. This means once your treatment is complete, you'll have a big, bold smile and an unobstructed airway. Demko Orthodontics also offers Invisalign, retainers, facial aesthetics, sleep apnea therapy, and Acceledent at our St. Charles office.
