Union Dental has been my go-to for over 15 years. Silly me tried a fancy dentist that charged double. Came back here—the ladies are amazing, make me feel right at home. Real people. My husband goes too and loves their care. Best dentist in Oakland for sure.

Been coming here for a while and each visit is great. Dr. Nguyen is super knowledgeable and explains everything so I feel comfortable. He's gentle with numbing and procedures. Paola at the front desk is friendly and helpful with scheduling and insurance. Honestly, couldn't ask for better dental care in Oakland.

Had a fantastic experience at Union Dental thanks to Paola and Josefina. They were warm, welcoming, and professional from the moment I walked in. They answered all my questions and made sure I was comfortable during my cleaning. The aftercare instructions were helpful too. Really went above and beyond.

Hands down the best dentist in town! Started going about 5 years ago for ortho treatment when I lived in the Bay Area. Now I travel from the Central Valley just to see them. Staff is super friendly and they really care. Worth the drive for dental cleanings and more.

Some good assistants here but there's one who's extremely rude, always has an attitude and talks mean. The front desk girls are sometimes mean too, nice when they want to be. The only problem is that one assistant. Otherwise, the dentist is okay.
Owner Response
We're sorry you had that experience. At Union Dental in Oakland, we take feedback seriously and will address this with our team. We want every visit to be positive. Please give us a chance to make it right.

Not 100% happy with the dentist's service, but for the money and distance I had no other choice. Office manager always mean, you can feel it in her voice. She threatened to call the police when I questioned her attitude. Her name might be Cynthia. Good luck if you go.

Not a good dentist. Barely cleaned my teeth, said I had 4 cavities without testing, and I was out in 20 minutes with a $400 appointment to fix them. If you want to tell your mom you went but don't care about your teeth, this is the place. Otherwise go elsewhere.
Owner Response
We're sorry you felt rushed. At Union Dental in Oakland, we aim for thorough exams and clear explanations. We'll review our cleaning and diagnostic process. Your feedback helps us improve.

Staff not very efficient. Called to make an appointment and was told I owe money for not canceling. I left messages to cancel. If I missed an appointment in March, how was I allowed to make another in July? Every time I ask for the office manager they say she's busy or not there. Left a message but who knows.
Owner Response
We apologize for the confusion and frustration. At Union Dental in Oakland, we're reviewing our cancellation and communication process to prevent this. Please contact us directly so we can resolve the billing issue.
