I hadn’t gone to a dentist for almost a decade before I found Dr Lee. I wouldn’t have neglected my oral hygiene for so long if I had found Dr Lee’s practice earlier! His thorough yet gentle cleanings have made me a loyal patient. The staff are all genuinely kind and courteous at the office. I’m patiently advised to floss each time without judgement when they can see evidence that I am admittedly lax in that area. The office is semi-private with each dentist chair located in its own room with an open doorway. I also appreciate being able to visit for Saturday appointments. My only wish is for the restrooms to be located within the office but Dr Lee’s skill is enough to keep me coming back.

They'll be your best friend if they think they can sell you something, but if they can't find anything wrong, they'll make excuses to drop you. Be careful not to get talked into unnecessary services. That was my experience.

Dr. Lum has been my dentist for over a decade. He's professional, trustworthy, and practical—always explains pros and cons before any treatment. Hygienists Agnes and Chelsea are thorough with cleanings. Front desk is friendly and accommodating. Appointments are always on time. Couldn't ask for better cosmetic dentistry care in Cupertino.

Highly recommend this office! I see both Dr. Lum and Dr. Lee—they're honest and caring. I'm a grinder and they've really helped me manage it. Staff is great too. Feel lucky to have found them in Cupertino for my dental needs.

Worst experience. Dentists were rude and didn't even go over my x-rays. Waited forever to be seen. Very unprofessional. Wish I'd done more research on Dr. Lee and Dr. Lum before going.

Got a cleaning that was the laziest I've ever had. Usually takes 30 minutes to an hour with a good hygienist, but this was about 10 minutes. Barely removed calculus—I can still see and feel it. The assistant's polishing and flossing were poor, and he hurt my tongue. Not what I expected from a dental clinic in Cupertino.
Owner Response
We're sorry your cleaning was not up to our standards. At Arnel Lee and Gary Lum, DDS in Cupertino, we take pride in thorough care. We'll address this with our team to ensure better experiences. Please reach out if you'd like to come back for a complimentary touch-up.

Been coming to Dr. Lee and Lum's office for about a year now. Usually just pop in for cleanings—Aggie is super careful and efficient. Had to come in for a filling once too, and they were quick to work with my schedule. Friendly staff, clean space, and they send prompt reminders. Parking's easy. Office is on the second floor with stairs or elevator. Great place for family dentistry in Cupertino.
Owner Response
Thanks for the kind words! We're glad you've had a good experience with our team at Arnel Lee and Gary Lum, DDS in Cupertino. Aggie takes pride in her cleanings, and we always aim to accommodate your schedule. See you next time!

Awesome service and doctors (and assistant). I highly recommend this clinic. I had pain and I didn’t understand from where is going - doctor fixed it and she didn’t do anything superfluous (I mean some doctors in other clinics just want charge from you extra money for superfluous service, but not here). Very careful, knowledgeable, I didn’t feel any discomfort during procedure. Thank you very much!

Dr. Lum is the best. Followed him from San Francisco to Cupertino. He's thorough and honest—doesn't suggest unnecessary fillings. Another dentist told me I had 7 cavities, but Dr. Lum said none. I've trusted him ever since. Great for cosmetic dentistry and general care.

Started seeing Dr. Lum last year. It had been years since college since I'd seen a dentist, so I expected a lecture. But Dr. Lum was motivating instead, telling me what I could do to improve. After a couple of fillings, I've been cavity-free for over a year! Great experience for family dentistry in Cupertino.
Owner Response
We're so glad you felt motivated rather than lectured! Dr. Lum loves helping patients get on track. At Arnel Lee and Gary Lum, DDS in Cupertino, we focus on positive care. Keep up the great work—see you at your next cleaning!
