  • Dr.
    Crystal Baik

    Dr. Crystal Baik has graduated from the University of Michigan, School of Dentistry in 2003, and in 2004, she has completed a residency in general dentistry at Evanston Hospital of Northshore Health System, where she received the advanced training in dental emergencies, prosthetics, pediatric dentistry, endodontics, periodontics, oral surgery, dental implants and cosmetic dentistry. Dr. Baik strives to provide comfortable and comprehensive dentistry to both children and adults. She spends ample time getting to know each patient and listening to their concerns because she believes dentistry is at its best when patients' dental fear or anxiety is first taken care of. When she is not in her office, Dr. Baik is most likely driving her son from school to sports and from sports to music lessons and she nags her son about flossing his teeth and drinking water instead of Gatorade just like many other moms.

    Dr. Baik is a great dentist! I first met her when I took my younger brother to take care of some cavities and then ended up going to her myself. I also recommended her to my older brother who went in and had two wisdom teeth removed. She was extremely friendly, good and quick! He had to get stitches put in and he literally walked in and out of her office. Extremely satisfied!

    Dr. Baik is very kind. She explains well very kindly about her treatment in order not that my kids feel scared of it. I asked her for my son's bracelet. She explained it well. In our position, she gives her opinion not for her profit. It's really great place.

    I will have to say this was by far the best dental experience ever! I went in to get two wisdom teeth pulled and it could not have been any better. I was EXTREMELY scared but the dentist was great throughout the whole appointment. The teeth were pulled with such ease and NO pain. Even afterward I still had no pain. Never thought this dentist visit could have been this awesome. Definitely recommend this dentist to my family and friends. And going back to get the other two pulled also!!!
