One of the kindest, and gentlest dentists you will ever go to. I was needing a couple of crowns and a root canal done and needed a new general dentist at the same time. At first glance I was a bit apprehensive because it wasn't a fancy office but I thought I'd give the place a shot and after meeting the doctor and his wonderful staff, I was so glad I found this office. Dr. Wu was very welcoming at the initial visit. He did the exam, found out exactly what needed to be done and although my case was a bit of a challenge, he worked with me and we went with what we were both comfortable doing. I was a dental assistant in the past for many years so I know how the procedure goes when examining patients, coming up with a treatment plan, and getting them to accept the treatment. I am no dentist but I knew based on my previous work experience that the treatment plan presented was the best route. It was for the longevity of my teeth, to save the teeth in question, and he gave very reasonable prices compared to what I've known offices to charge for crowns, root canals, etc. The treatment wasn't easy at times but I knew what to expect. I didn't numb easy when treating one tooth but doctor Wu took care of that as he didn't want me to feel any pain at all, which I appreciated very much. Even though I have a high tolerance for pain, a drill to a live nerve is never fun for anybody. He worked as gently as possible but very efficiently. I felt very comfortable in the chair and in fact I dozed off during treatment on the several visits to his office. I did have to come back several times to complete work on two teeth but the doctor and staff made that as painless as possible as well. It's been several months now maybe almost a year since I had those teeth treated and I must say I am very impressed. I still have those teeth which I thought I'd have to lose but Dr. Wu did struck an awesome job in saving what was left of my broken down bicuspid and a molar with a huge cavity. I can chew on both sides again with comfort and ease. Even though it wasn't one of those state- of- the- art looking offices, it's quite nice in there and the staff is very welcoming and caring. The quality of care is especially what's important and Dr. Wu's office definitely has that. I don't write many reviews but I felt that this office does such an awesome job but is very underappreciated here on Yelp. So, if you're from the Walnut area or nearby and you're looking for a dentist who will do the best quality of care for your teeth and not charge you an arm and a leg for it. Head on down to Dr. Wu's office and they'll take care of you, promise! read more
