I dread having to go to a dentist, so much in fact I've put it off for 5 plus years. It was finally time to go in for an oral evaluation. So with the recommendation of my sister I hesitatently made an appointment at Diamond Bar Dental Studio. From start to finish Diamond Bar Dental Studio went above and beyond to make me feel welcomed and comfortable every step of the way. With Lily at the front desk booking my appointment to answering all my questions about my visit. Then Angelic the manager breaking down my dental plan answering and explaining every question I had regarding it. This dental office has some of the coolest tech I've ever seen. They scan your teeth to give you a 3d image of your mouth that you can rotate, zoom in and out, switch to different orientations like what your bite looks like, what your gum health looks like. I never knew I had a crossbones and Dr. Jeon was right there with me explaing everything I was seeing on screen. TL:DR, Diamond Bar Dental Studio is hands down the best dental office I've ever been too. From the helpful and caring staff to the insightful Doctors to the cool "high tech" technology they utilize. I know without a doubt im in good hands and i dont dread coming to this dentist office. I have my battle plan now and I'm ready to get it done. I cannot recommend then enough.

Dr. Cho reviewed my 3D scan, and diagnosed me with a Comprehensive Invisalign case. I got my old Invisalign attachments removed by Dr. Jeon since my prior dentist misdiagnosed me with a limited case. Erika, the amazing assistant removed all excess bonding around my attachments , which was never done at my previous office. This office is dedicated to absolute perfection, and continuing to stay up to date with all current research in dentistry. I am referring all of my family and friends here.

I have had two treatments Dr. Blanco and he is fantastic. Very comprehensive with his review, explaining everything in layman’s terms and showing me pictures to better understand what was going on. I appreciated that he looked at the overall health of my dentaI care. He gave me options for my care, including short term and long term care. I opted to take care of everything and get a retainer also. I previously had a dentist make me a retainer and it hurt to apply. When I mentioned that to my previous dentist, he just claimed “that’s not how it should be”, but things did not resolve. I came to Dr. Blanco as I heard that dentists go to him to get their teeth fixed. My friend is a dentist and thought he was highly skilled and received Invisalign from him, so I decided to go to Dr. Blanco for a retainer. They use Invisalign technology, and with my prior issue with my prior dentist, I did not want to take a chance with another unfitting retainer. With regard to my dental care, I had many cavities as a child and the fillings I had done then had begun to crack. He redid my fillings and placed a temporary crown with expertise. When I mistakenly popped off my temporary crown (I was told not to floss with a particular floss and I completely forgot and was aggressively flossing haha), he fit me in same day to refit another one! My crown came in 3wks later and I now have a crown on my molar that is completely color matched to my other teeth! So happy! I also appreciate how Dr. Blanco interacts with his staff. Today he had a new dental assistant and he asked her to bring out her notebook to take notes, then while doing the procedure, asked her to rehearse the steps, then teach him. I’m a huge proponent of “see one, do one, teach one” for active learning so I was pleasantly surprised when Dr. Blanco deployed this method. He was always polite and respectful, and I saw through my appointment the assistant get proficient in each step in real time. She did amazing too! Needless to say, I will be coming here and referring my friends here for future dentist appointments!
😘 One of the best Dr Cho 🤍Doesn't hurt!

I brought my girlfriend here because of her wisdom teeth pain, and it was somewhat of an emergency. In my experience, this is the only place where you can have all four wisdom teeth extracted within 10 minutes, yet still very safely! I have met many dentists, but he is definitely the best for sure! Thank you, Dr. Cho, and all the staff; everyone was so kind!
