I have visited Dr. Yu a couple times for different things, including endodontics and tooth cleaning. He is very kind and professional. No matter it’s a big job, small job, or even a job free of charge, he always does the best, careful and gentle. From my experience with multiple dentists, I can tell that Dr. Yu is a well-trained and outstanding dentist. His assistants are nice, pretty and professional too. I surely recommend Smile Back Dental Group to my friends

The best dentist’s office I’ve ever visited, we have been visiting this doctor for over ten years, we have very good experience with them, the employees are very friendly and good with people, my kids love to go there for their dental care. Thank you all so much for keeping our teeth clean and healthy.

I got my braces done with Dr. Yu and that was the best decision I’ve ever made. My teeth started showing progress the third month I had it on and ever since I got it off it has been perfectly straight. Dr. Yu is always so patient with me every month when I come back for check ups, he checks not only the braces but other problems with my teeth and recommends the best treatment.  His assistants are very nice and fun, too! Office is sparkly clean and the equipments aren’t like any where else. Definitely recommend Dr. Yu’s office if you need any thing regarding your oral health!

Two days ago, my daughter fell on the ground and got injured on her front tooth. I took photos and sent to Dr.Yu which showing  the tooth nerve exposed. It was off hour but Dr.Yu went back to his office to treat my daughter. He said it would be painful if not to treat urgently. Now my daughter feels no pain and I have much less worry during the weekend after Dr.Yu treated my daughter. Thank you Dr.Yu.

The best dentists ever, my friends and I were both treated our wisdom teeth here. Dr. Yu is very skilled, I pulled out two wisdom teeth at the same time, and recovered fast. And Doris, front desk, really helpful and friendly, she helped us to check our insurance coverage and always remind before the appointment. I would like to introduce this place to my friends.

My daughter solved her underbite problem by Dr Yu last year. Now she is very happy and thankful to Dr. Yu.  Dr, Yu :”Thanks for your magic hands !” You are the best !!!

Dave L. from Novato, CA (Source: Yelp)


I had some financial problems for a while last year and took advantage of some specials Dr. Yu was running on root canals and crowns. I ended up traveling from out of the area and each occasion went smoothly. I was also very fortunate, as others have alluded to, that he was able to accommodate me for longer appointments as necessary- I believe I was there for 5 hours on several occasions when I anticipated an hour or so due to unforeseen circumstances (needed additionaly work done on other teeth). Overall, Dr Yu is patient, honest, compassionate and skilled, speaks good English (but you should be patient), the office staff and location were wonderful, and I would highly recommend going here if you need work done.

Very nice and knowledgeable dentist. Great office location and staff. They truly helped my mother it was a great experience. They were willing to make payment options if necessary. Also, they were very accommodating with scheduling.

I am not a fan of the dentist and getting my mouth worked on. I absolutely loathe going. I got a mailer from this place when I was dealing with a broken tooth that I knew would need a root canal. I don’t have dental insurance or much flexibility in my finances for that matter and I needed to find a good dentist that wasn’t too expensive. I was weary about going somewhere new so I figured I would go in for a consultation and see what my initial instinct was before proceeding to the actual dental work. When I went in I felt very comfortable and asked to schedule my next appointment to get the actual dental work done and they said they do it on the spot. This has NEVER happened in all my years of going to the dentist. So I stayed and had the work done that day. I was scared because I have had some negative dental office experiences, but Dr. You was the most gentle dentist I’ve ever had. I felt no pain during or after the procedure. I have been back several times and continue to get quality care. I highly reccomend!

I’m impressed by Dr Yu’s professional skills & experience which demonstrated by his work on us customers. He has a great & kind attitude towards each and every patient that visits his dental clinic. And he’s always been very patient with every customer. Plus, the equipments of the dental clinic are mostly top-notch & very up-to-date. Also, the environment & ambience is very nice & upscale. Honestly, compared to some dental clinics with many old rusty out-of-date equipments which charges similar prices, I feel more like a perk going to this clinic that’s clean, tidy, modern & up-to-date with skilled dentist such as Dr Yu as well as his team members. I’d recommend this dental clinic.

I made an appointment with Dr.Yu’s office for the first time this month. I called and the girl spoke on the phone was nice and welcoming, it was east to get the appointment time I wanted! I got here on time and Dr. Yu was very helpful with the problem I had just by looking at the X-ray and in person. The process was quick and that goes to show how experienced he is! He’s really good at what he does and I decided to go with his treatment plan right there and then. Today I came back and got the procedure done, it was done fast and professionally! I’m happy with the tooth and I’d come back if my other teeth are acting up, lol!

DR Yu is AMAZING. Anytime I feel that things are an emergency he gets me in ASAP and treats my daughter so good. Thank you. I appreciate the entire staff in that office. All are amazing.

Roc C. from Chino Hills, CA (Source: Yelp)


Dr. Yu is very professional and nice, he takes your situation into serious consideration, and makes the best plan and rate for you! Whenever you have any question, just go back to ask him for double checking for free. I did my filling here, as well as taking off my wisdom tooth. I feel much better now! He takes all PPOs, so do not worried about the insurance. If you have dental problem, just comes to Smile Back Dental! You will smile as much as you want!

Johnathan A. from Newport Beach, CA (Source: Yelp)


Dr. Yu did an amazing job! He was very patient and understanding while I and my tongue moved around as I was a little nervous. It was a marathon dental appointment which lasted over 2.5hrs. He had to remove a old root canal, install a new one, put in a post, fix a broken inner tooth wall that went under my gums and get things ready for for a crown that I will have installed in about 2 weeks time.
No regular dentist could have undertaken this…. I would have had of visited 1 specialist first and then a regular dentist and wasted a lot of time and gas traveling around. I would recommend him for all dental work as he really is a specialist. Thanks again Dr YU!
