Do not suffer in unnecessary pain from a dental emergency. We offer emergency dentistry and will minimize your pain and suffering. We offer same day emergency dental appointments.
Root canals are a common procedure that our dentists use to save and repair a severely decayed or infected tooth. The inside of your tooth will be cleaned and sealed all in a comfortable setting.
Most patients have their wisdom teeth extracted because they are impacted and cannot come in. After removal, you will heal and be back to normal in a few days.
Start your children out early in life with good oral hygiene. Our gentle prevention, treatment, and education is the best way to keep your kids teeth and gums healthy.

We are driven to pursue excellence in their dentistry. On top of having acquired their DDS degrees, they both continue to study the field of dentistry. New techniques and methods are continually being developed, and the Diamond Bar Dental Studio team’s desire is to master every new development in the field.

As the years progress, we will continue to maintain a cutting-edge knowledge of dentistry as the field grows.

Before & After Smile Dentist Gallery

Did you know that your smile is your best accessory? In fact, when you are not smiling, it has a significant impact on how others perceive you. Are you unhappy with your smile? If you are, then there is a good chance you don’t do it often enough. If you avoid smiling, it is most likely because you are unhappy or ashamed of the appearance of your teeth. Many people have low self-esteem because of their smile confidence. Maybe you don’t feel your teeth are white enough, or they are crooked, chipped, or missing? Aside from feeling better about your appearance, did you know that smiling more tells your brain that you are happy? It is a boost to your health! 

At Diamond Bar Dental Studio, our Cosmetic Dentistry Treatments have helped many patients regain their smile confidence. Take a look through our Before & After Gallery and find out how you can be proud of your smile, too!

Like most people, I really don't like going to the dentist. And I avoid it whenever possible. Dr. Jeon made me very comfortable and put me at ease. I tend to be anxious and she explained everything that would happen and what she was doing. I would highly recommend Dr. Jeon to anyone looking for a knowledgeable, gentle dentist with an excellent bedside manner.


I called Dr. Cho because of a dental emergency. I was in so much pain and stress because I thought I would have to wait all weekend before seeing a dentist. Dr. Cho was accommodating, comforting, and really did everything he could to turn a bad situation into a manageable one. I can't thank him enough for his kindness and flexibility. I would highly recommend Dr. Cho to my family and friends (and anyone looking for an excellent dentist).


Best dentist I have ever been too, and that is truly the most genuine compliment that can be given as I am a practicing dentist myself. I trust no one else with my teeth and my own dental needs. He is an exceptional dentist and I truly love his work and attention to detail. He prides himself in quality and I value that a lot.

-Rhonda K

The staff is great and very welcoming and knowledgeable. I have moved around a lot and have been to many different dentists. Dr. Cho is great! He does great work in terms of quality and comfort. I have to drive 40 miles to see him, I'll keep doing that because great dentist's like him are hard to find!

- Jeffrey G

Only place I will ever go for my dental needs. The staff pays so much attention to little details and ensures that every client is satisfied with the service they get. I have sent many people to their office and every single one of them was amazed by the services provided by Diamond Bar Dental Studio!!!
