A Different Kind of Orthodontic Practice

PureSmile Orthodontics was founded on a simple belief: every patient deserves a beautiful, healthy smile — achieved with precision, care, and the most advanced techniques available. Located in Chicago, IL, our practice combines Dr. Qingshan Li’s three decades of international orthodontic expertise with a warm, patient-centered environment where you and your family feel genuinely welcome.

We treat patients of all ages, from children as young as seven receiving early Phase 1 treatment to adults who have waited years to finally pursue their ideal smile. Whatever your situation, Dr. Li designs every treatment plan with three goals: optimal function, beautiful aesthetics, and long-term stability.

Dr. Qingshan Li

Dr. Qingshan Li is a board-certified orthodontist with over 33 years of experience across three countries. His career began in China, where he first practiced dentistry before pursuing advanced training in Germany. At the University of Kiel, he earned his PhD in dentistry and completed postgraduate training in restorative dentistry and orthodontics, where he also became a certified orthodontist.

Dr. Li further refined his expertise through an orthodontic residency at the prestigious Eastman Institute for Oral Health at the University of Rochester Medical Center in New York — one of the most respected orthodontic programs in the United States.

Now based in Chicago, Dr. Li treats patients across multiple locations while remaining active in orthodontic research and education. His work has been featured in renowned academic journals, and he regularly presents at both domestic and international orthodontic seminars. In addition to his clinical work, he serves as a faculty member at the University of Illinois at Chicago (UIC), mentoring the next generation of orthodontists.

Treatment Philosophy: Dr. Li’s philosophy goes beyond simply straightening teeth. He designs every treatment plan with a focus on functional bites, facial aesthetics, efficiency, and long-term stability. Using advanced digital planning and an efficient case management process, Dr. Li completes treatments in less time than traditional approaches — achieving non-extraction results for over 90% of his patients. His goal is always the same: to create a smile that lasts a lifetime.

Beyond the Office: Outside of orthodontics, Dr. Li enjoys swimming, traveling, and photography. Most importantly, he cherishes time with his family.
