Our Testimonials

I went to Bay Star Dental for a cleaning and wisdom tooth extraction. Both processes were very smooth as the front desk, assistant and doctor were super friendly and experienced.

During the exam in the cleaning, Dr. Zhang went over the xrays and photos with me and explained everything in detail. He took time to answer many questions that I had about my condition and that was really much appreciated.

For the extraction visit, I really enjoyed how both Dr. Zhang and assistant Joanne would help me distract myself from the needle and hold my jaw while pushing the tooth out. The procedure itself was really quick and overall almost painless (can't run away from the anesthesia pinch, right?).

I love how Bay Star Dental feels so cozy and will definitely come back for my future cleanings!

Years ago, I got in office zoom whitening and my teeth still look great!

I’ve visited many clinics throughout the years after that but at this clinic, the dentists are experienced and passionate about their work.This time my dentist, was able to combine his expertise with care. He also provided me with excellent aesthetic advice to help me achieve my dental health needs and aesthetics goals.

The office is small, clean, modern and tasteful. And the dental assistants are professional and kind.

I would highly recommend this clinic for regular check ups, fillings, crowns, zoom whitening and veneers.

Bay star dental is exceptional. I called with pain issues and was given an appointment the same day. Lynn returned my email and I was in. Dr Zhang was open and honest with my options. Highly efficient and quick, he made me feel comfortable and relaxed. I especially appreciated the classical piano in the background to distract from drill sound. Overall I would highly recommend Bay star dental and will certainly be returning for any future dental work.
