My girls had their first dentist appointment here at Childrens happy teeth today, they both did so well and the doctors were amazing and sweet and made all of comfortable and made it fun for my children. My girls were excited to be here and gave the doctor no problems. And the dentist was really gentle and went over every single step for my girls. I highly recommend this dentist for all children.! We will be back in 6 months!

I was referred to children’s happy teeth through another dental place to get second opinion and I was very happy with the time they took to explain and provide other options for my daughter who had previously had a lot of work done. For our first time visit here I had a good experience with my daughter Dr. And assistance was very caring and did anything to keep her entertained. Hope to continue experiencing the same treatment during our next visit.

Children’s Happy Teeth Is the best pediatric dentistry we have been to. The Dr.’s and staff are very friendly. The office is child-friendly, toys and tablets for kids to play while waiting. They also have movies on all the time. It’s very clean and organized. Before the procedure all questions were answered and everything was explained thoroughly. I definitely recommend them.

Kim V. from Riverside, CA (Source: Yelp)


This pediatric office is beautiful.  Dr. Zadeh was so kind & sensitive to my grand kids. They each had 3 cavities. Not my fault, I’ll blame the parents for giving them candy….no seriously the office staff were exceptionally attentive, the dr great & everything about Children’s Happy Teeth was perfect. I know we will be starting braces there as well! Thank you Tooth Fairy for recommending your office!!!

Best Dentist I’ve ever been to, they were very good with all of my children, made them feel so comfortable, my 2 year old didn’t even want me when she got her xrays and she loves the dentist now. I am able to stay with my kids through their procedures, and the Dr. Makes sure to give me a thorough list of options and walks me through each one so I can feel supported in choosing what’s best. So happy to have found this place.

This is the best Children’s dentist and I recommend for anybody who has kids to bring their little ones here. They are so welcoming and make my child happy to be going to the dentist. We are always excited and looking forward to it because they provide the best dental experience each and every time. I am very happy with children’s happy teeth and will continue to come here. Thank you for all that you do! And for giving children the best experience when it comes to dental care and hospitality!!

It’s hard for me to give any establishment a five star rating especially a dentistry but this one takes the cake. I’ve had such horrible experiences at the dentist from a young age (at now 28) and I only wanted to give my daughter the best experience possible so that she isn’t turned away as I am. We did have to wait a little bit in the lobby even though we had an appointment but that’s wait was nothing considering how great our appointment went. For reference, my daughter is a little over 2 and this was her first dentist appt. I was so nervous for my daughter because I wasn’t sure how she was going to react but I of course tried to make it sound like this place was going to be awesome even before walking in. Dr. Yasmin had my daughter lay on top of me which was very smart since there was little to no chance she would’ve just got on one of those dentist chairs herself. There were movies playing right in front of her but she was too distracted by the light and the tools that the Dr. yasmin used. She made all her tools come to life by telling a story and singing songs and my daughter happily obliged since I was holding her and she was so gentle with her. The checkup went by really fast and we were luckily enough to be informed she had zero cavities and that she had a few molars growing in. Dr. Yasmin gave her a certificate and then she got to go to this prize wall where she got to choose any toy of her liking. My daughter and I walked away so encouraged and pleased that an establishment like this exists for children. Can’t wait to go back in six months!

This is the most amazing dentist office around. From every member of the staff to each dentist and oral surgeon we have met they seem to be the absolute very best in the field they are in. My 5 yr old jumped up out of bed at 6 am for a 2 hour plus drive to come see here favorite ppl Maggie and her dentist. She absolutely loves them. My oldest had a very scary oral surgery today and as always the staff was amazing thank you all so much.

Our 3-year old daughter was crying and complaining of what we thought was a toothache.  We called the dentist that we had previously been to but could not get through.  We tried again later and got voice mail so we left them a message.  After not receiving a call back, we called Children’s Happy Teeth that same day and they took us in 45 minutes later!  They were very nice and professional.  They found that our daughter did not have any cavities and that it was an “aphthous ulcer” on her gum that was causing the pain.  They cleaned her teeth and told us that the ulcer would heal in 1-2 weeks.  Best of all, she did not cry at all!  When we got home there was a message from our previous dentist stating that they could see her in 2 weeks.  Needless to say, we have found a new dentist!

Donielle F. from Long Beach, CA (Source: Yelp)


This was my daughters first dental appointment and it was amazing. The front lobby had toys and movies playing to keep the kids entertained while you feel out paperwork. The dental assistant that gave my daughter her x-rays was amazing and so patient with her. The dentist was amazing and my daughter enjoyed the visit immensely. She was able to watch a movie while getting her teeth cleaned!! I am so happy to have found this dental office.

I ended up coming to this office because my insurance changed. I have to say it was a blessing  in disguised. My daughter (8 years old) loved it so much that when we had a chance to go back to previous dentist and we didn’t. I love that I get to go in with her for treatment. All dentist are so sweet and patient. They explain the plan before hand. My daughter didn’t even feel treatment. She always walks away happy. They also have the orthodontist there too. We love the orthodontist and staff as well. After having 3 consultations with other offices we choose this one. I loved that they explained the process and they didn’t start by trying to remove all teeth. So far everything has been amazing! I have to say they been doing great with accommodating patient through this pandemic as well. They sanitize everything constantly and take kids and parents temperature upon arrival.  With limited people in the office.  Great job Happy Teeth!!

Lizbeth R. from Long Beach, CA (Source: Yelp)


Great clean and kid friendly dentistry. my daughter unfortunately needed a baby root canal after her first check up and they couldn’t have made the process easier. The dentist was very nice and so was the stuff. Something so scary to me they were able to keep me and my daughter calm. The only downside I would say is when calling to confirm they only gave me about 4 hours to confirm appt or else I would be fined $50 and appt would be cancelled. I had to clock out of work for a bit to return their call and confirm . Other than that pretty great!

We would love to say “Thank You” to Dr. Yasmin Zadeh and Dr. Eshaghian for treating our son with tender loving care. Our son had his first dental surgery ( hopefully his last ) and needed to be put under (anesthesia). Both My husband and myself were nervous wrecks and both doctors were very professional, nice, explained every step and made us both feel comfortable and put us at ease. The office personnel very welcoming and very caring. We knew our son was in great hands. We appreciate you all and would recommend your dental office to anyone.  The La Voie Family

Say no more! For years I’ve been trying to find a dentist for both of my boys and each time I have been u successful. They were either A. Too rough/unsympathetic or B. Had hidden ridiculous charges for unnecessary dental work. I’m so glad my coworker recommended this Dentistry. I was recommended to the original office in La Mirada when my 6 year old was crying of pain. They were so awesome and he felt nothing. The staff was awesome and just a reflection of the dentist herself. Once I found out they were opening up this location in Lakewood (much closer to my home) I was ecstatic. Extremely apprehensive as there are some business’ that often fall short on other locations, I was hugely mistaken. I’ve grown to love this location if not more. Now my older son is receiving Ortho care, must I add how affordable and the plans they extend for braces. I always recommend this dentistry whenever anyone asks.

I had originally taken my 3 year old daughter to a very different regular dental facility nearby, and did not have a very pleasant experience. The dentist and workers there did not know how to work with kids at all. As my daughter has gotten older, I knew it was necessary to find a pediatric dental facility where the dentist and workers had a lot of experience working with children. I found Children’s Happy Teeth on Yelp, and am so glad I decided to bring my daughter here. Dr. Yasaman was so pleasant. She really helped to comfort my daughter and calm her anxiety about coming to the dentist. The front desk and dental assistants were very friendly as well. The lobby has three tablets available for kids to play with while waiting, along with several books and a table with some toys. The wall and furniture decor is super kid-friendly. Their facility is very clean – even the bathroom is spotless! I had originally scheduled my appointment with the Lakewood facility, however, I was unknowingly booked for the La Mirada facility. So, when I showed up for my 11am appointment, I was not on the Lakewood calendar. I was only showing up on the La Mirada calendar. I ended up having to wait 1 1/2 hours to see the dentist due to the mix-up, which was much longer than I had anticipated on waiting. I will say that the experience ended up being worth the wait. Just make sure when booking your appointment, you confirm the facility location so there’s no mix up! Thank you, Dr. Yasaman! I know my daughter won’t be feeling quite as anxious when it comes to her next dental check up.

Today was our first visit to Children’s Happy Teeth and all I can say is AMAZING! From the very first time I called to make the appointment the staff was amazing and when we arrived they were super helpful. The area as you walk in has toys and tablets with lots of games for kids to play while they wait. My son, who dislikes doctors, didn’t even realize he was at the dentist. Dr. Yasmin approached my son so friendly that he cooperated (he’s two) which I never thought was going to happen. She was gentle, caring, and acknowledged it was his first visit. The assistant was super friendly as well. We will definitely be back and we recommend this place to anyone!!!

A year back my daughter had a bad experience at the dentist. I was in a search for a caring and kid friendly dentist. Came here to Yelp and found Children’s Happy Teeth . The reviews captured my interest. I called Children’s Happy Teeth, the receptionist was very kind and informative. They scheduled me that same day even though they go by appointments which I was very grateful because I have a very tight schedule. They staff and Dr.Yasmine were so kind and friendly my daughter felt safe. Needless to say, we went back for a dental procedure couple of weeks later. My daughter was very calm. She was not worried about the procedure, she felt safe and trusted every decision Dr. Yasmine made. At the end of the day my daughter said ” mom never change my dentist, she is great!” When your kid trusts and feels safe with a Doctor you know you have found a good place.

I will write everything I have told my mom friends about this place. If you are looking for a dentist for your little one, you can stop now. Call and book an appointment. My daughter just turned four last week and her first dental appointment was only last month. I waited and waited to take her to the dentist because I have anxiety about visiting the dentist and I was scared that if I took my daughter too early that she might also be traumatized I found Children’s Happy Teeth on Yelp and was happy that they accepted my insurance. I was so excited to hear that they were accepting new patients. I brought my almost 4 year old daughter as well as my 20 month son. They loved this place! Upon entering you are welcomed with friendly staff and bright colors. Multiple flat screens playing children’s movies from Netflix, tablets for the kids, yes, electronic tablets for the children and other toys for the really littles. The staff are super friendly and sweet and all are really good with the kids. They use all types of diversions and cute stories to explain what they are doing. My daughter ended up having “sugar bugs” so we needed to come in a month later to get those “sugar bugs” out! While booking the initial appointment I shared with the receptionist that I was nervous that my kids would hate the dentist. She assured me that they wouldn’t want to leave. Wouldn’t you know it, upon leaving, both of my kids were hassling me to stay longer!! I have been bragging about this place for the last month to all my mom friends, especially the ones that haven’t taken their kids to see the dentist yet. I really urge you to try this place just as I have urged them. You won’t regret it.

I love this place! From the staff in the front, to the staff in the back, the service is outstanding! My daughter was comfortable and relaxed. She had to have one root canal and a filling done at the visit. The doctor was patient and sweet. Her assistant, Ruby, was so kind! I loved everything about our experience and will be returning every 6 months for their check ups. This will be our regular dentist from here on out.

Maria S. from Lakewood, CA (Source: Yelp)


After 2 weeks of a horrible  experience with Western dental I found this place on yelp and through my fears and worries, happy teeth has won me over.. all the staff are exceptional.  The environment and the Ambiance is extremely kid and family-friendly. I am overwhelmed and I appreciate the experience we received. Gisela greatest us as we walked in the door, giselle the assistant  was amazing in her care for my daughter and the doctor new her work and made myself  and my daughter happy. .. 5 stars are not enough to rate  the experience and care

Sashi A. from Signal Hill, CA (Source: Yelp)


Upon entering the office I was warmly and promptly greeted. Paperwork took just a matter of minutes and the girls t the from we’re  very friendly.It was my son’s first visit to the dentist and it went beyond awesome. I’m still new to the area and was so happy to have found Children’s Happy teeth. As soon as we came in my kiddo loved the place. Clean, bright colors everywhere and a wonderful kids corner with books, games, kids movies to entertain. We did not have to wait too long to see the doc. Doctor Yasmin was a peach and my son felt very comfortable. The assistants helped keep my son comfortable and happy.  Before leaving my son got a certificate of a prefect smile and a small toy (too cute)  an absolute thanks to Adrianna, Michelle, Victoria and Dr Yasmin for the awesome first visit.  See y’all in six months!

Cecilia G. from Norwalk, CA (Source: Yelp)


Been bringing my kiddos here for a few years, every time we come we get excellent service. Now with Covid they take the best precautions in the office. I feel really confortable bringing my kids to their dentist appointments. Now that my daughter is getting ortho treatment the staff there is also awesome. And I love it that it’s in the same office no need to go somewhere else. I recommend this place 100% for kids of all ages

Highly recommend Children’s Happy Teeth My kids had amazing experiences both being terrified of the dentist. We got greeted by Angela whom send me all the paper work via text message and went over with me what to expect coming into the office with all the new changes they have done due to Covid-19. The X-ray tech Diana did such a good job and was very gentle while taking my kids X-rays. and my daughter by Dr.Yasi both assisted by Maria she was amazing with my kids such a great energy which made them feel so comfortable throughout the exams and cleanings and explained everything we should expect the day of treatment. On our way out Flor helped me with my insurance and helped me schedule both kids for treatment. My daughter saw Dr.Yasi Tran to get a tooth extracted both her and her assistant Rubi where so gentle and carrying with her During the extraction making sure she wasn’t scared and understood what was going they stopped when she needed a breaks and even sing a song to help her calm her nerves which was so sweet. Again I highly recommend this place!!

So happy with this place. We are new to Cali from North Carolina and I called them and they scheduled us immediately. Some other places I called before said they wouldn’t take new patients until weeks/months from when I called. So they made me feel welcomed from that initial call. The office was so cute it had things (toys and iPads) to keep my 14 month old and 7 year old entertained while we waited. The staff was so friendly and smiley. They make kids feel very confident and secure. The visit was informative and I did not feel rushed. All my questions and concerns were discussed. Not to mention my 7 year old LOVED the toy wall. I would definitely recommend them to anyone.

Tina A. from Lakewood Mutual, Lakewood, CA (Source: Yelp)


No cavities 3rd time in a row!!!!!!! Yay!!!!! Happy Teeth is awesome. My grandson loves coming and is always calm, they are wonderful working with special needs. My grandson has autIsm and Happy Teeth are great wIth helping him to be calm and at ease, they show him and explain things to him, he loves coming here, no screaming as he did  at the other place, finally a place that we can feel comfortable bring him to.

Sheena S. from Compton, CA (Source: Yelp)


Took my daughter Sophie in today for her first visit since she’s only two, the entire process was painless I filled out my welcome paperwork and was called shorty after. We were scheduled at 9am and were completely done by 9:35am dr. Yasmin and nurse Maggie were great at making Sophie comfortable and even singing and showing her the tools through the process, I recommend this office to anyone with children they will love it and so will u as a parent, see u guys in 6 months

Ana H. from Torrance, CA (Source: Yelp)


Staff and doctor were so friendly and great with my daughter. The customer service was extraordinary. I am so happy I found this office on yelp. My daughter is 2. Her 1 yr old appointment was scary and not good for her. I was scared of her seeing the dentist again because she had a hard time the first visit (somewhere else) but I was so happy and surprised it went well. The methods they use here are exceptional and I am so glad my daughter did good. She was still scared and crying but not like the first time where she was terrified of the other place. This office is so cute and kid friendly. So happy!

Nikki C. from Lawndale, CA (Source: Yelp)


I would definitely recommend this place for anyone with kids. They are absolutely amazing. Everything from the front desk girls, the dental assistants, and the doctor are phenomenal. I took my 2 1/2 year old to a dentist a few weeks before I found this place and it was an absolute disaster and he cried the entire time. I come here and not a single tear. They made him feel so comfortable he even went with one of the assistants without me to grab a toy. Thank you happy teeth for making the dentist a fun experience for my toddler.

Manuel H. from Lakewood, CA (Source: Yelp)


Amazing place to bring your kids to their dentist appointment.  The lobby has iPads and toys for the kids to loosen up before they go in.  The dental technician personnel does a pretty good job in keeping your kids calm and cooperative.  The decoration is nice and does a good job smoothing our kids mood.  They even let my wife and I step inside while they we’re going thru the whole dental and check-up procedure.  We’ve been to other dental offices that don’t allow parents inside.  Also I like how they will text and call you to remind you of the appointment.  We will continue bringing our kids for their dental check-ups.  We definitely can recommend this dentist office to our friends and family.

Angela K. from San Francisco, CA (Source: Yelp)


We took our infant daughter for her first check up to this dentist office, and it was a wonderful experience! There was a little mix up with the insurance but the staff was extremely patient and helpful with the whole process. The visit itself was very smooth. Because of COVID-19, you need to call once you arrive before walking into the office for the social distancing which is completely understandable. Parking is easy and the staff were super friendly. They even gave my daughter a toy for her first visit! We will be coming back every six months for her routine check up! 🙂

Shameka B. from Lakewood, CA (Source: Yelp)


I have to say upon walking through the door of my first visit the entire staff was so welcoming. The entire staff has always made my entire family feel very welcomed. All  the information I was given was very thorough, I would definitely recommend this children dental to anyone who’s looking in the area. There was definitely a lot of things that stood out to me, but what made this particular children dental experience to me was unlike any other experience was how thorough they were about the billing prior to any dental work, explaining everything from top to bottom, no hidden agenda at all.

Mrs M. from Los Angeles, CA (Source: Yelp)


I would like to extend a HUGE THANK YOU. When my grandson  woke up this morning, one of his baby molars was hurting him so badly, he couldn’t eat breakfast. He and mom were on vacation. Mom called around 8:30 am and explained they were out of town visitors,  and couldn’t wait till they got home to see my grandson’s re regular dentist. I couldn’t believe it when they were able to squeeze him in by 10 am. Nothing is worse than a child in pain,  except being in pain, far from home on summer vacation. It turned out, the  molar needed to be pulled and another one needed a cap. Mom came home with a glowing report about the office, the dentist, and how well my grandson was taken care of. The best part of the visit, was this very cool souvenir. Thank you EVERYONE at Children’s Happy Teeth La Mirada.

Mikayla L. from Long Beach, CA (Source: Yelp)


My daughter was referred here by her Dentist for a consult. I called to make the appointment, and the scheduler on the phone was very sweet. She booked us for next week, but later in the day left a message asking if we wanted to come in at 9 am or 11 am, but unfortunately I did not call back on time and they were closed! But I took my chances and went to the office at 8 and called them in the parking lot & the women on the phone told me to come on in! We walked in, and greeted by 4 ladies. The staff is very welcoming!! Filled out paperwork, and less than 15 minutes probably quicker than that me and my daughter were pulled to the back and she was getting her Xrays done, then her cleaning. The dentist was so nice and calming, and she explained everything to me that was going on with my daughters teeth. We both will be back since she has treatment to be done! The clinic is very clean, and definitely a place designed to make kids comfortable at a dentists office!

Ben R. from Long Beach, CA (Source: Yelp)


After recently moving to the area, I brought my sons to Children’s Happy Teeth for a check-up/cleaning at the recommendation of another dentist.  My sons are 5 and 3 and experience some anxiety when it comes to dental visits.  Happily this visit was mostly anxiety free for them.  The staff is very friendly and good with kids.  The process involved a lot of transparency for the kids (showing the instruments, explaining the procedures), some nice imagination (ice cream toothpaste), as well as plenty of distraction and entertainment.  They even got rewarded with toys, balloons, and certificates.  My sons are happy and hopefully going to the dentist will now be a more stress-free experience.  I am happy to recommend Children’s Happy Teeth for your pediatric dental needs.

Nora H. from Lakewood, CA (Source: Yelp)


My 11 and 8 year olds already LOVE going to the dentist, but our original one retired. We were looking for somewhere close and had lots of options. Both kids had cleanings and some other work done. ALL the staff are friendly and knowledgeable. The kids really loved the time they spent there. My 11 year old also started his orthodontics at Happy Ortho, and everything made him feel comfortable and it went smooth. Looking forward to the next 2 years and beyond!
