      I took my daughter for an initial consultation and 2nd option on some recommendations provided from another practice.  Dr Rubin and his assistants were incredible. Professionalism, knowledge, expertise and making my daughter comfortable.  She even gave Dr Rubin a hug after her check up.  Needless to say we are now proud patients of Dr Rubin & Lonestar Kids Dentistry

    Lonestar Kid’s is amazing! I brought my 1-year-old daughter in for her very first dental exam, and the entire experience was wonderful! I struggled with a lot of dental anxiety growing up, so finding an office that would help my daughter feel relaxed and comfortable during her visits was a huge priority for me.

Katie, the dental assistant, was so sweet and explained everything very clearly, and Dr. Sentelle was incredibly gentle and thorough throughout his exam. The entire team made us feel so welcome and cared for!

I highly recommend this office to anyone looking for high-quality, compassionate dental care for their littles!!

    We have been going to Lonestar Dentistry for over 10 years! They are amazing! Engaging and patient with the kiddos. Dr Rubin remains engaged and answers questions for both my 17 and 7 year old have in ways they both appreciate and understand. I am fortunate that I found them all those many years ago! I couldn’t ask for a better team to see and keep my kids on the right track with their dental needs. Thank you as always!

    Wonderful experience! My 4 month old required an evaluation for lip and tongue tie… we had his tongue tie addressed and it went very well. Dr. Sentelle was very professional, knowledgeable, and worked well with my baby. The staff were all very friendly and helpful. It was a breath of fresh air seeing how professional, and courteous everyone was. Thanks girls! I’ll definitely be moving my 3yr old over to seeing Dr. Sentelle too. I would recommend they rotate out some of the toys in the waiting rooms, some of them are pretty worn.

    We have seen Dr. Sentelle for both my kids the past year. We have been very pleased with the entire experience. From the booking, each staff member we have encountered and Dr. Sentelle have all been amazing and made the experience so smooth. Both my 5 and 2.5 year old have left their visits happy and enjoyed their experience as well which is saying a lot for kids getting their mouths checked etc. would definitely recommend!

    We have seen 6 different specialists trying to find answers for our infant’s feeding problem. They were by far the most diligent and kind of them all. Brina and Aubrey were nothing short of perfect and helped ease our worries as we got a lip and tongue tie resolved. Thank yall so much for everything!

    We had the best experience! We checked in with Myra & she was wonderful with both my kids. Our hygienists were so kind & patient. Dr. Sentelle was so helpful & answered all my questions. We checked out with Brina who was so sweet! Going to the dentist with little kids (3 & 18m) seems scary, but everyone was really amazing & made it a place my 3 year old was begging to go back to!

    So impressed with this dentist office.  From the dental assistant Myra and the hygienist Whitney who made my daughter feel so comfortable to Rachel and Stephanie at the front desk who were so nice and welcoming; I would absolutely recommend this office for your kids dental needs.  They are the best I have found in to whole DFW area and I love their more holistic approach which is extremely hard to find.

    We could not be more happy with our experience at Lonestar! My daughter had to get her tongue and lip tie revised and we could not have had a better experience. They walked us through the entire process and made us feel very comfortable with what the recovery process would look like.

    My son had another amazing visit to Lonestar Kid's Dentistry! It always feels like we are visiting family. 🙂 He saw Ms. V. today for a friendly dental cleaning. She complimented him  on his daily routine and encouraged him to keep up the good work. My favorite part was how excited he was to implement Ms.V's flossing and brushing suggestions. 😁👏👏
