We (entire family now) have been coming to see Dra. Bangsil for almost 10 years now.  Even when moved out of state (we now live in Las Vegas), we still come to see her.  Her staff are all wonderful – from the front office personnel, assistants, the hygienist and even her office manager Ruby!  We have had any procedure you can imagine (implant, root canals, even teeth whitening, etc.), they can handle them all.  They are open every other Saturdays which makes getting an appointment easy.  If you are looking for a family dentist office, this is the place!

I was peer pressured to make this review by the desk guy (jk) to make this review, but I suppose it’s a great dentist place with good dentist tools and a nice bathroom. I’m no dentist expert but their equipment is really top of the notch stuff. The dentists are chill and funny. I come here basically every week and one of the dentist ladies calls me Trisha, but it’s cool. I’d say this dentist is family friendly as well. Also big shout out to Larry, the desk boy, for the wifi password. 10/10 would definitely come again.

Amazing experience!!! If I can only give 100 stars, I would. As soon as I walked in I was greeted by Larry at the front desk, he was very friendly and up until the end of my consultation he made sure that I was ok and I get my treatment plan squared. Next, Dr Lea Bangsil is just beyond – professional, friendly and gave me options. Dr Bangsil made me feel that I am in good hands and at ease…highly recommended!!!!

Dr. Lea Bangsil has been my doctor since I was 8 years old, I will be turning 21 this year and till this day I have not had one bad experience with them. I always leave very satisfied and happy with the way they work. The staff is also very friendly and welcoming! Celina attended me so well! Not to mention Larry the receptionist who makes my day with his jokes! He’s also so understanding and flexible with rescheduling. Thank you Larry! Overall I rate 10 out of 5 stars and definitely recommend it.

Dr Bangsil an her staff are extremely professional, friendly and competent. I’m very grateful to have found Dr. Bangsil and would highly recommend her practice to anyone looking for an outstanding dental office. Larry is funny and friendly, Ruby and Zoila are awesome.

Cai R. from Buena Park, CA (Source: Yelp)


I’m surprised nobody has ever reviewed this clinic. Dr. Bangsil and her staff are very friendly and their dental work is impeccable. The lady in front who explained to me the treatments that needed to be done never rushed me like other clinics and she even presented the treatments to me by priority as she wanted to work with my budget. I highly recommend this clinic as they are very honest and I felt their genuine concern. They weren’t after my money and they definitely made my smile better.

Enrique C. from Whittier, CA (Source: Yelp)


Dr Lea Bangsil has been my primary dentist for about 15 years and I couldn’t be happier. Her team is as amazing as she is. They make me feel right at home from the minute I walk in. They are friendly, professional, courteous, and they always do it with a smile. I completely recommend..

Jaclyn C. from Long Beach, CA (Source: Yelp)


We started coming here about 5 months ago.  I had a cracked tooth . The front office is so welcoming  and made it easy to understand all the paper work . Larry is seriously  the best he makes the time waiting go by fast. The back office is so nice and always makes sure your comfortable.  If you have any questions they will answer them for you.  Myself husband in laws and children all come to this office.

Claudine R. from La Palma, CA (Source: Yelp)


Everyone here is so friendly and the doctor was very helpful with my situation that I had. They’re very good at calling back and following up, which I very much appreciate. They called me about 3 times in a week, to follow up, referral me to another doctor for my wisdom teeth and to schedule an appointment for my fillings. I will definitely come back for their services. The staff was great. If you’re looking for a good dentistry and kind people, this is the place.

The experience here at Smile Big Dentistry has been nothing less than spectacular. There are very few words that can describe Dr. Bangsils work ethic and brilliant skills and talent. I’m so happy that I found the perfect dental office for my needs and more important the needs of my children. I have been coming here well over 10 years and I could not imagine going anywhere else. In addition to having a great doctor, staff is awesome. Where should I start? Well, Larry is the funnest person on the planet. Ruby is super professional and great with insurance and treatment plans. I’m so blessed to have them all in my life here at the dental office. Love you guys, thank you for everything.

I have been coming here for over 15 years! My husband now gets his work done here as well. Honestly  they are the best dentist  that I have been too! Dr. Bangsil is so good with her patients  and she does what is best ALWAYS! Its not everyday when you come across a office staff like this one, they really do care about there patients well being and also work with you with the financial stuff. My husband  was brought lunch at his work by one of the staff members here! If you need a great dentist this is the place!! Take my advice don’t think twice! 😉

Larry C. from Fullerton, CA (Source: Yelp)


I started coming here well over 10 years now. It is by far the best dental office I have ever been to. I could use words such as “amazing” or “fabulous” however they are insufficient as to how I personally feel about this office. I feel welcome and appreciated by the entire team, everyone is so nice and helpful. I could never go anywhere else, when I am in the care of Dr. Bangsil, I am at ease and I already know anything I get done will be painless. There are two Doctors there on some days which helps with wait times however I don’t care how long I wait for the best care possible. There is also a hygienist on site two days a week which is wonderful when I need to maintain my cleanings. Dr. Bangsil is always great and always very informative of what she’s doing during any procedure, even a simple check up!  I love coming here! I have had almost every procedure done here, from fillings to braces… If you want quality dental care, come here, I recommend it.

I have found a dentist worthy of the gods! This office is amazing, spectacular, efficient, professional, and I could go on and on with this all day (I’m not joking). I found this dental office over 8 years ago, they have been so good to me, my children, family and personal friends. I rage about this office to anyone that will listen, I’m telling you this place has set the standard for dental treatment for the rest of my life. Where do I start? Okay, Dr. Bangsil is skilled and knows how to take care of any type of procedure. She has a very light hand, the movement of a skilled heart surgeon. I’m amazing how I never feel a thing – she is wonderful. Ruby is professional and very knowledgeable with treatment plans and insurance. I love her to death. Now, Larry is from another planet. He is welcoming and makes us all feel like family – he has a beautiful heart. Thank you for everything Smile Big Dentistry. Love you all.

The people who work here are Great. They have great customer skills. Dr. Bangsil
is one of the best dentist my family and I have ever had. We are not afraid of going to the dentist anymore. Highly Recommended.

Roxanne C. from Buena Park, CA (Source: Yelp)


Dr Bangsil and her team are awesome. I’ve been coming here for over 5years, along with my kids. They do a great job with whatever is needed and I never have a problem. I will be recommending my friends and family to her and her team.

Cecilia H. from La Habra, CA (Source: Yelp)


My husband and I were so glad to have visited this clinic last year. Everyone is genuine and friendly. Definitely here to stay for a loooong time!

Teryn B. from Fullerton, CA (Source: Yelp)


I love this office. Everybody honestly treats you like you’re their family. I took my boyfriend here for a second opinion after another dentist told him he would need a second root canal (after performing one less than a week before on the tooth next to it) to stop the horrible pain in his mouth, costing us two thousand at least. Dr. Bangsil not only determined that he did not need a second root canal, but found a blister along his gum. She had it removed and the pain is now almost completely gone! She listened to what my boyfriend had to say and explained how the blister was more than likely the source of his pain. The procedure took less than 15 minutes. Not to mention the staff. Ruby the office manager is knowledgeable and helped me deal with insurance after I told her I had forgotten his insurance card. She was able to pull up his information without it, and Larry went over the cost of the procedure with us, cracking jokes the entire time! Bottom line, I love this office. The office staff is great, and Dr. Bangsil and her team of dental assistants really knock the ball out of the park. Thank you so much!!!
