I will keep this review short, but stay away from his office Jump to the end for my recommendation.
I went to Dr. Cheung for 15 years and he did a lot of dental work for me. Despite my hesitation about how he worked on me, I continued to go because I thought the final work was good. Like others here, he argued with his staff in front of me many times, going from English to Chinese when the arguments really heated up. He left debris in my mouth after he finished working on me. He cut my lip and he refused to send me to an endodontist for my 5th root canal telling me that I didn't know what I has talking about, and that it was "no big fat deal" and that I should just go home and let it settle down. What he had missed was 4 absesses at the tips of my roots on the tooth in question. He had not taken an x-ray of the top of the tooth where the problem was.
I had a new crown crack on me after 10 days, which he promptly replaced, but it was always mis-shapen until my new and better dentist replaced it.
If you go to the 8th Floor of this same building, you will find a much better and more sensitive dentist at Oakland City Dental. The dentist on the 8th floor is a real find!
About Front Desk: Ended up going over my insurance amount without my approval and I was hit with $3K of charges. This office is poory run.
