Exceptional and Professional!

Dr. Kim and his staff are exceptional. He is professional, but also extremely gregarious. I appreciate his ability to provide a great wealth of knowledge during procedures, and to review options using explanatory devices such as images and videos. A really great experience.

Dr. Kim is amazing!

Dr. Kim is amazing, he's very patient and he explains you everything step-by-step. He's perfect for young millenials, too, because he's willing to explain insurance-related questions and stuff.He even shows you the xrays and pictures through the flat screen in front of the chair! I really appreciate the transparency by explaining to me what's happening and steps I can do to fix it. He doesn't push unnecessary operations because he does give you options and pros and cons of each one. I also like that he's nice but he doesn't sugarcoat anything. He will tell you if you're doing something wrong with your routine and tell you how to fix it! Will definitely visit again. He makes you comfortable!

Boston Dental was great!

Dr. Kim and his office were great! I was able to send all of the forms and paperwork prior to the visit eliminating the need to take time for that and it was typed and printed and ready for signature upon arrival. The front staff was helpful and immediately called my children back for x-rays. Dr. Kim did the cleaning, viewed the x-rays and discussed everything he saw with me in clear terms. He was sure to ask me if I had any questions and was great about discussing the importance for brushing and flossing to my children. No task was beneath him; he even scheduled our next appointments! He had a great approach, was quick, gentle and seems knowledgeable. He understands my insurance and is willing to work with me; we even discussed suggestions for future insurance decisions should I need to make a change. My children wee relaxed, happy, and he even fixed my daughter's slightly chipped tooth! I'm very pleased and glad that we found a great dentist in Rockville.

Award Winning Dentists

Boston Dental Group (BDG) was founded over 10 years ago to affordably and safely treat people with various dental problems and help patients maintain healthy teeth and a healthy life.

BDG offers a full line of dental services and procedures, including dental reconstruction, whitening, dental implants, dental cosmetics, crown bridges, and other general dentistry. Boston Dental Group differentiates itself from other practices by having three dental physicians on staff who provide more specialized and professional services.

Dr. Sung-Joo Kim, chief dental physician, and two other doctors, including our director, Dr. Jacqueline You, coordinate their specialized knowledge of dental medicine to provide detailed and effective solutions to patients' problems. As a full one-stop shop, BDG also has a dental hygienist on staff who helps in the treatment of patients. This elite team of dental professionals provides accurate early diagnosis and builds detailed and individualized treatment regimens based on daily team meetings.

Dr. Sung Kim

Dr. Kim graduated from University of Maryland at College Park with BS degree in Biology and received his D.M.D. from Boston University. Dr. Kim believes in a treatment system where the patient is an active participant in the process through patient education and thorough explanation. BDG utilizes sophisticated Caesy dental education system to help patients understand the dental issues and the logic behind each treatment. The result of this patient-centric approach is
significantly reduced problems during the post-op recovery as the patients understand their role in the overall dental care.  Dr. Kim believes even if the dental physician is sitting in the driver's seat and performs the procedures, the patients need to know why and where they are going.
