my experience was good and not bad but not great as well

Karl Lum is very nice and well treated and gave complete details about the dental treatment

Dr. Lum was very professional and answered all questions. Office staff was great and proactive.

Very polite and experienced doctor

An incredible experience! All the reviews were true. He is the kindest dentist I've ever had. He did a great job of walking me through all the processes and procedures. All the hard truths he laid down were done kindly and without judgment! He was also very good at answering and quelling all my curiosities. I have no anxieties about coming back. I'm glad I scheduled my next appointment with him! Now, time to floss so I can make doc proud!

Dr. Lum and his staff are personable and friendly, and they make you feel right at home at the office. They’re all knowledgeable and can explain anything in good detail. I especially appreciate the ample parking spaces in their office lot!

Awesome Dr. Felt better after appointment.

appointment was for my son and doctor was so caring . He gave us clear instructions and they were helpful. I would recommend him !!

This was my first visit and everything went through smoothly. Dr. Karl was patient and diligent with the treatment. I will definitely. refer friends.

Really awesome dentist! Left my teeth feeling whiter than ever before, and was detailed in explaining what/why behind procedures, and what to expect. Recommending my family and friends in the Fremont to this dentist soon.

Very good

Dr Lum was very professional and meticulous! I felt super cared for :D

Really easy to set up an appointment and verify my insurance. Dr. Lum was really friendly and so were the other staff members! Appointment was efficient. Got done with filling out forms, x-rays, and teeth cleaning within an hour.

Took x-ray even though I had one six-months ago, and took measurements such as teeth to gum distance, which seemed like a lot of diagnostics without cause, but I suppose it was the first time seeing him. He gave a mirror and showed me some things in my mouth, which a dentist has never really done before during a routine cleaning, which was nice. He stressed flossing technique, particularly behind the last tooth in the back of the mouth, which was the first time a dentist had told me that as well. At the end, his assistant put on a sticky layer of fluoride that was supposed to restore minerals, which is generally only given for children, but that they stated they are now doing for adults too for cavity prevention. He was a bit aggressive on the cleaning, and my gums were sensitive to cold water for the next couple of days, so not the best if you have sensitive teeth.

Very thorough, kind, and friendly atmosphere. Definitely knows his stuff, and does his best to make all patients feel comfortable.

Dr. Karl Lum was very patient with all my questions. He answered all my questions and provided good explanations. One of the best dental visits I had in the bay area!

I really enjoyed my visit starting with the receptionist,dental assistant, and Dental Doctor. Very clean ,friendly environment. Dental Doctor examined my teeth 🦷 Very professional . Was so enjoyable I made my follow up appointment for next 6 months.

Very insightful and cleaned my teeth really well!

Dr. Lum was very warm and welcoming for my first visit and was able to thoroughly explain the process. I was in and out with no issues! Great experience.

Dr. Karl is so nice and pro!!! I really like him. I think I will make him to be my dentist going forward

He is very nice, staffs also nice. Dr Karl explained things very through. Martha also patiently explained to me what I need to do. It was a great office visit experience.

Good doctor. Helps in understanding the process

Good staff.good detail description of the job to be done

Very professional. Staff is very personable and not just there to collect a paycheck. Martha is extremely friendly and helpful. Dr. Lum is amazing. Will definitely be back.

It was a good experience. The Dr. actually talked to me about my options for my dental care and let me make decisions. I didn't feel like I was being pressured into procedures that I wasn't ready for or weren't necessary unlike I have at other dentists.
