Dr. Duy Bui

Just Laughs, Just Smiles, Just Kids!

Dr. Duy Bui

DDS,MS

I am from Orange County in California and am excited to come to the Bay Area to practice orthodontics. My interest in orthodontics began when I had braces at the age of 15, and it has never waned since then.

After receiving my Bachelor of Science degree in Human Biology at the University of California, San Diego, I relocated to Northern California to complete my Doctor of Dental Surgery degree at the University of California, San Francisco. While at UCSF, I explored my passions for leadership, research, and teaching. I served in numerous dental and outreach organizations while also contributing to research on the effects of social determinants on oral health.

I left sunny California to brave the harsh winters of Michigan to complete my training in orthodontics at the University of Michigan in Ann Arbor. I pursued my passion for education by conducting research on virtual reality teaching methods in dental education. I received extensive training on many different orthodontic treatment modalities including but not limited to, traditional braces, functional appliances, clear aligner therapy, surgical orthodontics, and much more. I am especially interested in the care of cleft lip/palate and other craniofacial anomaly patients.

Additionally, I received both the Aldrich Scholarship Award, as well as Rackham Block Grant award during my residency program. I have become a die-hard Michigan football fan who bleeds Maize and Blue. GO BLUE!

During my free time, I am an avid fan of basketball and tennis. My favorite players are LeBron James and Roger Federer, respectively. When not out on the court, you can find me playing video games with my family and friends. I also love to spend time trying new restaurants and attempting to cook with my fiancée. I am also a proud member of the American Association of Orthodontics.

Dr. Brian and the team are great with following up with families. We love the family-friendly environment in the office!
Reshma P.
Friendly. Explained everything. Answered questions. Tech was wonderful and engaged with my son. Dentist was wonderful and friendly and fun with my son.
Cindee C.
My 18 month old had his first dental appointment ever here and it was such an excellent experience. They are quick, they give options to the kids and parents to make them comfortable, the explain everything they do, and did I mention quick! I don’t think my son realized the doctor was doing anything to his mouth, he was so gentle. Dr. Brian sang softly to my son while he examined his teeth and gums and answered all questions we had about his dental care. We even got a commemorative photo to put on our fridge to mark the occasion. I’m so glad we came here.
Edith L.
Dr. Chang and the medical assistant were very friendly and accommodating. Thank you for being so gentle and understanding with my son, who is on the spectrum.
yien A.
My kids had a fantastic experience at their recent dental check-ups. Both had their teeth cleaned, and the staff was incredibly gentle and caring, especially with my son who had a cold sore. They were patient and made sure he was comfortable throughout the entire cleaning. The dentist and the team were also great about answering all of my questions and concerns. It's clear they genuinely care about their young patients. I highly recommend this practice!
Sandeep H.
My son and daughter have been patients at Just Kids Pediatric Dentistry & Orthodontics since their very first visits, and we’ve always had a wonderful experience. Dr. Rattan is kind, relatable (as a mom herself), and truly knows how to connect with kids.

Today, my son was cared for by Alondra, RDA, and Dr. Rattan, and they made what could have been a stressful visit into a comfortable one. My son was nervous, but with their patience, kindness, and encouragement, he felt at ease throughout the process. Dr. Rattan even gave him the confidence to have his loose tooth extracted, something he was completely opposed to before coming in.

At Just Kids, treating children with respect and nurturing them through the process comes naturally, and it shows in every interaction. I’m grateful for the care and highly recommend this practice!

P.S. the prizes help too :)

This was our baby’s first dental visit at 7 months old, and everyone here was soooo amazing! The office is definitely giving “just kids” vibe, which we loved. The tooth fairies here are super nice and friendly. Dr. Jeff was super friendly and sooo good with our baby!
Response from the owner:Thank you for your wonderful feedback! We are thrilled to hear that your baby’s first visit was such a positive experience. Our team is dedicated to creating a fun and welcoming atmosphere for all our little patients.

Great first time experience at this dentistry today. My son felt so welcomed seeing his name on the board when we arrived - great personal touch! The dental assistant and dentist were both very nice and professional. The space is clean and comfortable and I'm confident I made the right choice for my son's dental needs.

Yamaha Y.
My personal experience at Just Kids Pediatric Dentist office has been nothing but positive! especially for my two daughters who always look forward to going to their dentist for work. The staff and office vibe in the last few years of coming here with my two children has been nothing but exemplary. All staff members from front desk to to the doctors and assistants that work there are awesome and very caring to my kids and are the friendliest and most knowledgle workers I have meet. I'm glad to be part of this great family and I look forward to seeing them when I take my kids there. I have nothing but love and respect for their work which is not easy but they always have smile on their faces no matter what! my kids and I appreciate them very much. It has been an honor for me to write my review. thanks again and see you all soon!
