At Sebastian Smiles Pediatric Dentistry, our purpose and mission is to provide preventative and curative pediatric dental care, which is imperative for keeping children cavity-free. Our dentists and friendly staff are dedicated to providing the highest quality and most comfortable dental care in a fun and caring environment for your kids.

We take pride in doing so in a pleasant and fun way, but based on communication, care and trust to ensure a lasting relationship with our patients and their families. One crown and two fillings done and a happy kid the day after. I can't say enough about how amazing the entire office staff is! They go above and beyond and have so many tricks up theirs sleeves to get an uncooperative child fixed up.
Services
You never get a second chance to make a first impression! We take that very seriously. Your first encounter with us sets the stage for an unbelievable experience for the entire family. From the first phone call where you are greeted by a friendly voice to the moment that you walk into our state-of-the-art office you will know that you are in for something different.
Dr. Keren Castellucci was born and raised in Central Florida. She attended the University of Central Florida where she earned a Bachelor of Science in Molecular Biology and Microbiology. She then attended Nova Southeastern University College of Dental Medicine in Fort Lauderdale, Florida where she completed her Doctorate of Dental Medicine.
Our mission at Sebastian Smiles is to make sure that your child has a lifetime of great oral health, and we want you to be a part of that mission. Here at Sebastian Smiles, we offer a multitude of services that will ensure that your child has clean, healthy teeth that will last a lifetime.

During this basic exam, parents will learn the proper feeding habits and basic dental hygiene for their baby or infant child and how to specifically address the dental needs that babies and infants have.Preventive care consists of routine cleanings that occur six months, regular x-rays to assess any potential damage, and regular fluoride cleansings along with the application of sealant to prevent tooth decay.
Each dental appointment is a span of time that we have set aside in order to give you and your child the attention and consideration that they deserve. With the help of our Patient Care Coordinator, we make sure that all patients receive undivided one-on-one attention. Our dentist takes enormous pride in seeing patients at the appointed time and giving them the attention and care they deserve.
Good oral health habits should start at an early age. We strive to make our presentations have a positive impact on children and give them a good start on having healthy teeth and gums for a lifetime. With younger age groups, small group presentations work best. We provide a lecture-demonstration that may involve activities and playing games.

Dr.Keren just saw my daughter for her very first dentist appointment, and she was AMAZING! She was very kind, sweet, and gentle with my daughter. She made us both feel comfortable, and my daughter was able to get her cleaning and exam done without crying or getting scared. The staff is very friendly, and welcoming. I would definitely recommend coming to Sebastian Smiles for your children!

I took my child for the first time for his first dentist appt, he is one year old. First of all he loved it from the start the office is welcoming and child friendly. They emailed me the paperwork so I didn’t have to complete it when I arrived which was great. The wait was about 5 minutes which was awesome and the staff was so professional yet so wonderful and helpful. The dentist was amazing and she knew what she was doing. The energy the place and the staff gave out was so positive. The experience was just wonderful. Highly recommend it.

The entire staff went above and beyond to make my 2 and 4 year olds feel comfortable. The front desk ladies are kind and accommodating with scheduling, explain all charges, and what to expect as far as insurance/out of pocket expense for future appointments. They allow parents (at least of small kids, as is the case for my family) to go back with their kids. The dentist and hygienists eased my sensory-sensitive 4 year olds fears by explaining everything they were doing before/after each step. Dr. Castellucci is fabulous with young kids and sings to my 2 year old to keep her calm and happy. I cannot

Awesome pediatric dental practice! The entire staff was thorough, informative and provided feedback for caring for my sons’ teeth. They focused on their problem areas with brushing and gave education following it. This was the most pleasant dental visit we’ve ever encountered and it really seemed like they genuinely cared about my boys’ oral health.

Completely kid based and super clean! Every wall has something to look at and even the floors are amazingly decorated. The waiting room has an interactive game room, and above each treatment area is a TV with kids movies playing. The hygienists are wonderful and parents are allowed to be with the kids every step of the way. The dentist is knowledgeable and skilled, and of course great with kids. Scheduling is easy and we've always been seen promptly. 100% satisfied and so glad we found them!
