    Ill-mannered, inconsiderate, and expensive, not to mention hot-tempered. Everyone should look for another doctor but him.

    This Dr is extremely ill mannered and explosive. He has no patients with dealing with people and gets angry easily.

    Chang, and he told me that bone grafting is impossible (too much bone lose), but gum surgery can be tried.

    I had oral surgery and a dental implant done at the Ueno Center in Campbell, and I couldn't have…read moreasked for a better experience. Dr. Ueno is calm, confident, and clearly extremely skilled -- he explained everything thoroughly and made the entire process feel very straightforward and stress-free. The staff deserves just as much praise. From the front desk to the surgical assistants, everyone was warm, professional, and attentive. They checked on me constantly, made sure I was comfortable, and somehow managed to make oral surgery feel ... almost relaxing (which I never thought I'd say). The procedure went smoothly, recovery was exactly as described, and the follow-up care was excellent. You can tell this is a well-run practice where people genuinely care about their patients. If you need oral surgery or implants and want to feel confident you're in great hands, I highly recommend Dr. Ueno and his entire team.

    This review is for Lynna Bui, whom I saw last week regarding gum recession concerns. Unfortunately,…read moremy experience was deeply disappointing and, at times, unprofessional. Most concerning was a note included in documentation emailed to me after the appointment. The note stated: "I really hope that mean lady (my name) won't schedule. Such a mean person." The comment was attached to Lynna Bui's name and profile picture with her family, clearly indicating she wrote it. Receiving internal remarks of this nature in patient documentation is highly inappropriate and unethical, to say the least. When Lynna Bui entered the room, she stated that she had been informed I typically take prophylactic antibiotics before dental visits and told me that if I chose to take them and wait, she would no longer have time to examine me. This occurred after I had already spent nearly an hour in the office and completed the required imaging and photographs, including a CT scan, all of which required payment. I informed her that I am immunocompromised, which was clearly documented in my medical history forms, and asked whether I could periodically rinse during the examination to avoid swallowing plaque or debris. Lynna, however, told me there was not enough time for that accommodation. While I could elaborate on additional interactions during the visit, the overall experience left me feeling dismissed and uncomfortable as a patient. Based on my experience, I would strongly encourage others seeking periodontal care to consider alternative providers, as I will be doing.

    Dr. Kao came as a recommendation to complete some work after my periodontist fell ill and was…read moreunable to continue practicing. I had an implant done, and he added additional bone grafting and gum work in the time slot that he had for me at no additional cost to help make the area look great. After 2 other bone grafts leading up to this one I was expecting to have some discomfort and discoloration of my gums. Surprisingly, I barely even noticed I'd just had a titanium rod shoved into my jaw and was eating normally shortly after the surgery. It took some serious mirror usage to discover that any surgery had been done. As the other reviewer noted, he's not comforting. I wasn't interested in comfort, I was interested in high-quality professional work, and Dr. Kao is the best I have been to.

    I had excellent results (note I've since left Silicon Valley)…read more First, he is a specialist, very experienced, so don't expect his demeanor to be very comforting. Like many Asian professionals, he is very clinical and doesn't go out of his way to soften your fears. Came to him as a referral for bleeding gums, and later on, for a molar implant after the root canal had failed. For the bleeding gums, he got me on a routine to use the inter-teeth brush pick.. It made the difference so my gums are restored enough that surgery wasn't required. My implant was very positive. My molar was close to a jaw nerve, and my general dentist was concerned about it. Dr. Kao didn't flinch and just did the extraction (2 minutes for 2 teeth), and after healing and he did the molar implant, and transferred the specs to my general dentist who did the crown. The implant (in 2005) was $2,000. As I said, his demeanor is straight forward and he's not very chatty. I needed results and he delivered.
