PATIENT REVIEWS

The care and compassion shown by Petite Dental & Orthodontics are hands down, the BEST! From day one of cleanings, to braces, to today, we have had a wonderful experience. Our children receive excellent care and feel important to all staff as soon as they walk in the door. Thank you for taking care of our family, Petite Dental! You are highly recommended!

I visited several orthodontist to see what was needed to correct my 11yr olds teeth. This was by far our favorite office. So far we have only been in a few times but I love the staff. Samantha (treatment coordinator) worked with me for several months to accommodate our financial needs, answered all of my questions about insurance coverage and directed me toward additional resources. Maddie (took scans and placed spacers for my daughter) was very sweet to my daughter. She spoke to her like a person and not a child, which was appreciated by us both. My daughter has dental anxiety but felt at ease here. Overall 5 stars. Thankfully all the offices we visited advised the same treatment plan so I feel confident we are on the right track. I do recommend visiting several offices to find the right fit for your family.

Petite Dental & Orthodontics is AMAZING! The staff is very kind, caring, and they make my kids feel comfortable. Taking my kiddos for their checkups is easy and very enjoyable! Dr. Hoang and Dr. Sint make a great team! I am thrilled that my kids can get all of their dental needs taken care of in one place by truly wonderful doctors 🙂 I wish I had had this kind of dental care when I was a kid 😉 I highly recommend Petite Dental & Orthodontics and more importantly, so do my kids!

Thank you for the wonderful care you provided for my 4-year-old son. He had a number of cavities to be filled and I was worried about how he’d do but you put him (and me) at ease and made the whole process go so smoothly. He did great and was feeling 100% the next day (even later that day I had a hard time keeping him resting ). Thank you! I’ve now switched all my children to your practice.

Both of my daughters have been going to Petite Dental since they were around 6 months old. We always have a wonderful experience!!! We feel so welcomed from the moment we walk in and until we leave. As an adult I have dental anxiety for myself and appreciate how comfortable they make my kiddos feel and how upbeat the atmosphere is.

UPDATED REVIEW: Petite Dental and Orthodontics are, as ever, an efficient, friendly and very professional operation. Our family uses them for both dental and orthodontic needs. Everyone, from the front desk to the assistants to the Dentist Kim (Dr. Hoang) and Orthodontist Noel (Dr. Sint) is friendly, informative, patient and really, really good at what they do. Extraordinarily kid-friendly environment, and yummy coffee for the parents. Our little boy has a blast when he visits. PD&O has proven to be a fantastic addition to our South Austin neighborhoods. Highly recommend.

My kids love this place. The staff is awesome. The kids are not scared but instead trust the Petite staff to take care of them, from a routine cleaning to a mini root canal to braces. The kids feel safe and not threatened. Very important for us when shopping for right dentist/orthodontist. Dr. Hoang and Dr. Stint are very knowledgeable and offer sensible oral healthcare advice. The facility is super clean with calming color palette and a kid friendly vibe. We were referred by a friend of the family to Petite. We are so happy that we have good friends:)

We had a great experience. My toddler wasn’t thrilled at times, no surprise there, but each time he started to get upset they were able to calm him down quickly. The dentist even sang the Thomas the Train theme song to him and he loved it! Left with a balloon in hand and a smile on his face.

Dr. Sint , Dr.Sint i was transfered over to him about 2-3 years ago.. He is an amazing Dr. he did everything he could possibly do for me. If i was late and i had to reschedule appointments he let me stay and finish.. He doesn’t  deserve lateness, but i am trying to show how much of a patient Dr he was. He made my smile look my mothers which was my dream since i started my braces road trip. He is an amazing Dr and i hope he continues that attitude i would refer anybody to him. BEST DR I ever Had!!!. I get compliments on how my teeth looks and its all because of him!!!!!.. He’s awesome

5 STARS BEST Children’s Dentistry & Ortho Care in AUSTIN!!! Dr. Stint was an answer to a prayer after my oldest daughter’s previous dentist retired. For my youngest daughter we had tried a couple of doctors, but they were not the right fit for our family. Doctors have to be both comfortable to the parents and the patient. In addition, the staff has to be amazing to handle the hassle of insurance too. Petite Dental works like a championship team with their friendliness, appointment reminders, follow ups, hip music in the waiting area, mannerism, patient bed side manners, media technology, coffee is always available for the tired parent, spotless waiting area, detailed dental plans, and teeth care. We found our home here, so I hope this review will give you an inside of Petite Dental from my experience. #petitedental #petitedentalfamily #bestpediatricdentist #bestorthodontist #atxdentist #atxortho #southaustin #braces #ortho #pediatricdentaloffice

I have been taking my 10 yr old son here for little over a year now and every single time has been the most wonderful experience. I’m allowed back with him but sit behind the doctor so I’m not in the way. My son (who is terrified of every doctor) is completely at ease each time. Time is taken to explain what is going on, what is being checked, what it may feel like and etc. Amazing pediatric dentist!!

It’s been 6 months since my 14 year old daughter got her braces off, and we are thrilled with how beautiful her teeth look. We were referred to Dr. Sint by a friend and so glad we chose here instead of another recommendation much further away. The deciding factor for us was they have early morning and school holiday appointments, so kids don’t have to miss school. Dr. Sint is a fantastic orthodontist and so easy to talk to. He always found a way to engage my daughter in conversation to help her relax. Everyone in this warm and welcoming practice always went out of their way to oblige our scheduling requests, and requests for my daughter’s favorite assistant, Alex. And I have to give a big shout out to Carly and Sammy, who were so warm, supportive and helpful when the unfortunate problem of breaking brackets and wires happened (only twice!). Love this practice and highly recommend!!!

I was deathly afraid of taking my two year old to the dentist because I had some traumatic dental treatments as a child.. After reading reviews for Petite Dental and hearing about a positive experience from a friend, we made an appointment. The staff was so friendly and great with our kiddo. We expected him to freak out but he was surprisingly good with the cleaning and exam. They did not rush and made him feel comfortable before doing anything. Singing songs during the cleaning made whole the experience fun… the balloon and prize at the end of the appointment had him smiling all the way home!

Love this place! My son and daughter have been going here for the last year. The staff is super on top of things and courteous. We never have to wait for more than 10 minutes to go to the back. The doctor is amazing! She always directs the questions towards the kids and makes them feel involved as well. Her and her staff has a lot of patience and even fillings take no more than 15-20 minutes to complete. I would for sure come here if you’re looking for a dentist for your little ones.

I came to Dr. Sint in Oct. 2012 for a consultation for braces. I was very reluctant to him, but he was wonderful with explaining everything that would be happening, all the instruments, how long it takes, and what’s going to be happening. Dr. Sint made himself available to me 24/7 for any problems or concerns I would have. It took us two years and two months to reach perfection, and I could not be happier with our end result. Since getting my braces off I can’t help but smile. I get compliments on my smile all the time and I have so much confidence now thanks to Dr. Sint. Thank you so much for being an amazing Orthodontist and making me comfortable with everything happening. Thank you my perfect smile and giving me all this confidence. Thank you so much!

I took my two year old here today and it was wonderful. We got there a little early so while we were waiting, the receptionist gave her an iPad to play with and then brought her a giant set of teeth and a giant toothbrush when she lost interest in the iPad. When they called us back, we were greeted by the super friendly dentist and her equally friendly assistant. They immediately let her pick out a tooth brush and made her feel so comfortable that she got right in the chair. They went out of her way to make everything seem fun and exciting to my daughter. The entire experience went 100% smoothly, which rarely happens when an almost-3-year-old is involved. Highly recommended!

So far, soooo good. First time patient registration process was easy and clear. Phone interaction for questions, setting appointment and follow up very easy with effective communication. Covid guide lines and safety assurance for patients and staff on spot. Staff very, very courteous, amicable and polite. In regards to the actual dentist’s activities my daughter didn’t complaint and felt comfortable the entire appointment. Information on what follows was clear and justified. In short I felt treated like a valued customer. Will definitely continue with treatments. This is a continuous process with people interaction, but so far, I’m impressed and very satisfied.

Both of my littles (3 and 1) are now patients here, and it has been nothing but positives for us so far. in fact, at our last visit, i was taking my 17-month old son for his first visit. i had wanted to get a picture of him during his first check up, but forgot. when we came back in to complete a part of the paperwork i had left blank, i mentioned the picture, and the staff was all over it. cleaned off a chair, gave him a little sign to hold and let me take my picture after the fact :-). it was very kind of them, and i felt valued. customer service lives!

We’re so grateful our friends recommended Petite Dental! Every visit is an amazing experience. The team is very talented and the culture in the office is genuinely kind & cheerful. They are quick without feeling rushed. And, each person is very knowledgable. Even if you have a dentist that you like, it’s worth going to meet the team to compare. 🙂  Thank You for being so great, Petite Dental! Sincerely, The Whitcomb Boys

If you’re looking for a kind, caring and progressive Orthodontist, who is also great with kids, check out Dr. Sint at Petite Dental & Orthodontics. He’s the real deal. My son just completed Phase 1 of his ortho treatment and I have nothing but positive things to say. Dr. Sint was always present and made sure to take special care in making my son feel at ease at each and every appointment over a 12 month period, with checkups occurring every month. He’s dedicated to his patients and precise and confident in his assessments, so I never had to worry. The team at Petite Dental are also top notch, always going above and beyond to make each patient feel like they’re a part of the family. We never have to wait more than a few minutes before being seen and our calls are always answered on the first ring. We’ve also had the pleasure of seeing Dr. Hoang for my son’s regular dental checkups. You’ll never catch her without a huge smile and sunny personality. She’s also progressive in her treatment strategies and extremely knowledgable. As an added bonus…they keep up with the times and play some great music in the office.

The entire staff at Petite Dental are always excellent! My older daughter(11) has a lot of anxiety about medical procedures and they always answer all of her questions patiently and now she enjoys dental appointments. My youngest (almost 2) had her first appointment today and she was crying as to be expected, but she didn’t freak out because I could sit with her on my lap the whole time. It went as smoothly as a dentist appointment for a toddler could go. The receptionists are always very helpful with scheduling and appointment reminders.

They really know how to take care of the little kids from the moment you walked into the clinic. From the front desk staff, to nurses and dental hygienist to doctors. Everyone is always smiley and gentle with my boys, they calmed down my active toddlers by showing them those dental tools are like toys and they won’t hurt. I highly recommend taking kids there for any dental issue, they will take care of your babies!

This was my Son’s second visit the doctor had to shave between his teeth to stop a cavity. My Son is 4yrs old and was very calm and willing to get in the chair and lay back and let them do the work. The way the team works to make my child feel safe and have fun is amazing. He did not put up a fight or cry at all. I would recommend them to any of my friends with young children.

This dental office is amazing! The receptionist is a sweetheart that makes you and your children feel right at home. The whole process was fast and thorough and the dental assistants are very knowledgeable! I feel like this office was made for families and will stay with them for a long time! Never have I felt this great about bringing my kiddos to a dentist, and they are excited to go! Truly amazing.

Petite Dental is the BEST office by far!! They have made my two yong children feel at ease with going to the dentist, and they have ALL been so sweet. We love Miss Kim and Miss Lisa. Going to the dentist isnt easy especially for young children, so for me to have no worries or concerns taking my kiddos in is a BIG deal. My son loves that he can ask Miss Lisa for her tablet and play in the waiting room until he is called back, and after everything he gets a sticker and a small toy 🙂 My daughter is a little tougher since shes younger, but they are so patient with her and try their best to make a connection so she feels more comfortable. They treat them so nicely and we will love them forever for that. HIGHLY RECOMMEND ANYONE TO COME HERE!!!

This place makes going to the dentist fun for everyone! Dentists give me anxiety, and my son has always had a hard time with doctors so I was especially nervous about his first dental visit – this place was better than I ever could have expected! Everyone is nice, from the front desk, to the dental assistants (like Ms. Pat!) to the wonderful dentists themselves. The place is beautifully designed for kids; it’s bright and inviting, everything looks and feels safe and unalarming. I wish they saw adults!

All the staff at Petite are knowledgeable, friendly and patient. They’ve been great at getting my hesitant four year old comfortable with cleanings and X-rays and even kept my four month old entertained as well! Full family service! Their offices are cute, clean and they’ve put a lot of thought into the full experience.

My boys are 9 & 7 and had their first visit to Petite Dental this afternoon (we recently moved to Austin). We were seen on time. The front office staff was helpful and pleasant. The hygienists who cleaned their teeth were quick, kind, and informative. The dentist was also thorough and great with the boys. We are happy to have found a great pediatric dentist on the first try!

As a fellow dentist and colleague I can say with confidence that Petit Dental does pediatric dentistry right!!! It takes a special set of skills that include great chair side manner and exacting technical precision to work with young kids and they have it all!! Their staff is so friendly and office is so inviting!  I have 2 little boys and I bring them to Petit dental and will for years to come!! I highly recommend this office for all your pediatric dental needs! – Tiffany Paiva, DMD

Exquisite practice, setting the bar high not just in the dental field but all medical/professional practices. Clean, family friendly & welcoming- from being greeted/checked in, to patient care, all the way to scheduling next visit and consulting with financial coordinator. Despite where you live, the commute is worth the visit ! Superb staff A++

I took my 2 year old in for her first dentist appointment and we love this place. Everyone was super quick, patient, and super friendly. They made sure my daughter was calm and they were very understanding. They even let my daughter pick out a toy and gave her a balloon. By the time we were done my daughter didn’t even want to leave! Would highly recommend to anyone.

I love this office (the actual building) & team. The office is always clean, fun and inviting. The team is friendly, professional, and if any dentist office was going to be considered fun, this one sets the bar. I really appreciate how everyone understands and knows how to work with young children (My son has been a patient since he was a baby) and also parents. They are super supportive and accommodate my schedule as a working mom and send reminders in various ways (I love the text reminders).

Dr. Sint was our orthodontist at another office and I was so sad when he left. I had no idea that he moved to Petite Dental, which is so close to our home. After 10 years with the first office, it came time to find another office because it was a 15 mile drive each way. I reached out for suggestions and discovered Dr. Sint had been right around the corner these last several years!! Without hesitation, I scheduled appointments for both kids, and it was the best decision. Petite Dental and Dr. Sint exceeded every expectation I could have had. So much thought went in to every detail at this office, including the environment, the staff, etc. … even the music is great! If only every doctor’s visit could be this thoughtful and amazing! I highly recommend Petite Dental.

Everyone at the office is fantastic. You can tell everyone loves working at this office because they are always smiling and so polite. My 18 month old hates when I brush his teeth. They were very understanding and polite when he started throwing his little fit. He loves the ballon they gave him as well as the little toy. They truly try to make the experience fun and less stressful for everyone involved.
