Check out what some of our happy patients are saying about us:

Dr. Thomas Wu and Dr. Helen Lai both work at this practice even though Yelp only lists Thomas Wu, DDS. In fact, they are married! Dr. Lai was my first dentist. I have been seeing her since I was 7 (16 years ago). The Good. Dr. Lai is professional and experienced. She recruits great people into her practice. They are not out to get the money in wallet. They are really looking out for my teeth and my health. They don’t drill random holes in my mouth because of “cavities” to collect money. She is great with kids. If you have kids who are scared of the dentist, she is great with kids. She has 2 kids of her own. Dr. Wu has cleaned my teeth couple of times and I am satisfied every time. I don’t have any problems with the receptionist but I have known them since I was a little girl. The Bad. They are not covered with many insurance companies. When I purchased UCLA’s dental group, Dr. Lai was not under their network. FINAL VERDICT. Dr. Lai is still my favorite dentist. I hope one day I will be covered by her network again!

Dr. Wu and Dr. Lai are extremely attentive and caring doctor. They go above and beyond to care for his patient. They dont just stop at caring for the teeth, they also extremely passionate about encouraging a healthy diet and lifestyle to maintain healthy gums and teeth.  They always explains all the procedures thoroughly and always maintains a cheerful demeanor. Coming to them doesn’t feel like coming to see a dentist, more like coming to see a caring family friend. I highly recommend these dentists, you will leave with a Hollywood Smile!

I’ve been at this dentist office since I was born and Dr. Wu and Dr. Lai have been more than stellar at cleaning my teeth. I know many people don’t like the dentist because of the fear of pain or whatnot, but the dentists here are great at their job. They are extremely friendly, and multilingual, might I add. The receptionists are friendly and they definitely know what they’re doing. I would 10/10 recommend this dentistry, despite what the other “not so great” reviews may say, because they are out of date and a lot seems to have changed. This dentistry is great for kids and adults alike! Also, they have NONE reserved parking spots; that’s super awesome!

I have to give Dr. Wu 5 stars.  I got a root canal here, maybe 5 or 6 years ago. About 3 years later, I got a crown put on it by another dentist, who was amazed at the thoroughness of his root canal work.  Dr. Wu had found all the roots (4!), and the dentist was confident when he put in my crown.  I had a deep cleaning a few months ago with yet another dentist, and she also complimented my root canal!  Seriously, these dentists were in awe. It’s a strange thing to be complimented on – Dr. Wu’s handiwork shines on. The front desk people may be irascible and hard to handle (this was ever the case, even when I went there in 2008), etc., but Dr. Wu does a solid, thorough job – which is all you could ever ask for, considering anything less will leave you with a rotting crown and more painful dental work.  Dr. Wu gets it done right the first time. If I ever need another root canal (and I hope I won’t), I will drive all the way back to Dr. Wu.

This morning was my second visit to Dr. Wu for a wisdom tooth extraction. He is absolutely amazing!! Since my insurance doesn’t cover any procedures with this doctor I am a cash patient. However, this has not made me explore other options. Dr. Wu is very friendly and welcoming. He has a very gentle hand and makes sure his patients are well taken care of. I would highly recommend him to everyone!

I’ve been going to Dr. Wu for almost 2 decades now. 16 years to be exact, first time there was having my wisdom teeth removed. Dr. Wu is a very easygoing, and honest person with a lot of patience and exceptional skills. He always spends the time to understand my needs and provides professional opinions. Like there is this one time, I told him that I’m interested in getting veneers for my front teeth, and I want to know how much it costs. The first thing he answered was not the price, he first told me the procedures and facts of getting veneers could possibly do a lot of damages to my healthy teeth which he would not recommend; then he told me the prices. Not to mention about my hard learned lesson, I once thought he was trying to rip me off when he told me I was having 3 cavities between 6 teeth during a regular teeth cleaning, so the quote for the filling was based on 6 teeth. I didn’t believe him and discarded his advice. One day which was 2 years after I started to have toothache, I knew it was bad. But I didn’t go to him, instead I went to another dental office starts with a “P”, because they were having a grand opening discount. BAD IDEA! I ended up with more toothache and gum infection. Because that young dentist simply drilled too deep and the filling was not polished smooth enough, and also an occlusal problem on one of the molars. It was just chaotic. Anyway, so I went back to Dr. Wu and he fixed everything for me patiently. That was a hard lesson learned. Because of that, I could totally tell the differences between a well experienced and practiced dentist’s hands and a younger dentist with high tech gadgets and nice interior dental office but not skillful enough hands….It’s very hard to find a trustworthy with exceptional skills dentist, at the same time not trying to rip you off, so I guess I’m stuck with Dr. Wu until he had to retire one day lol.

I’ve been coming to Dr Wu & Dr Lai’s dental office as a kid and they have been great through out the years! The office staff is super nice, despite what the reviews say. Everyone is welcoming, friendly, never had any issues. I’ve had my baby teeth pulled here, 4 wisdom teeth pulled (easy and painless experience), and teeth cleaned every 6 months, with Dr Lai, then Wu, and now Shaw. My teeth are straight and white and I thank the the doctors and staff for their combined efforts!

I have been going to Dr. Wu’s office since 1996.  We were looking for a dentist for our three year old at the time.  I didn’t want him growing up with the same fears of the dentist I had. Our insurance, which happened to be an HMO at the time, referred us to Dr. Wu.  They explained that he and Dr. Lai had a great reputation with kids, and boy were they right on.  I was so impressed with Dr. Lai and her gentleness with my son, I myself became her patient.  I’d like to add, that if you’ve had an issue here because of pricing or an HMO, maybe the issue is in fact YOUR HMO and NOT Dr. Wu’s office. From the first time we called to make an appointment Niko was warm and friendly.  I completely disagree with any negative remarks regarding her being rude.  On the contrary, she often took interest in our family and always welcomed us with a smile.  Unfortunately Niko is now retired, and we miss seeing her on our visits, but wish her well. As for the current staff at Dr. Wu’s office, they too are warm and friendly.  I appreciate how comfortable they make me feel, as I had many awful experiences before I found Dr. Lai.  We always feel well taken care of by Dr. Wu, Dr. Lai and all their staff. Fast forward twenty-two years, and my son is still a patient of Dr. Wu’s office today, as am I.  We have referred many friends and family that have also been extremely pleased. Lastly, I’d like to say after being a patient for all these years, Dr Wu and Dr. Lai truly care about their patience.  Recently my father in law who has no dental insurance needed a procedure and Dr. Lai worked with us to make sure he could get the dental care he need. I’d highly recommend scheduling a visit with Dr. Wu or Dr. Lai.  You couldn’t be in better hands.

I’ve been going here since 2002, I love this place. The staff is basically like another family for me. They always remember me and treat me like I’m a part of their family. I wouldn’t trust ANYONE with my teeth other than Dr. Lai or Dr. Wu.
