Pediatric Dentistry of One Loudoun


The staff is friendly, courteous and very patient. Dr. Rivas-Cuello is knowledgeable, very professional and knows how to handle a child who might be afraid of a dental procedure. This is a great team of professionals providing outstanding service. The office is spotless and beautifully decorated. Thank you Dr. Cuello-Rivas and staff. You are the best and I am thankful for you.
Town Hall is now preparing Welcome Kits for new families that are moving into our community. Our Welcome Kits feature and direct these new families to a small number of local businesses for the goods, services & professionals that they need to find. Since our Welcome Kits are exclusive, and we can only accommodate one Dentist, I would ask you to kindly let me know if you are interested in being the featured Dentist in our local Welcome Kits. It is worthy to note that, according to Dr. Cathy Goodwin in her book “Making the Big Move”, 70% of new residents and families seek out a new Dentist shortly after their relocation. As such, 7 out of 10 recipients of our Welcome Kits are actively looking for a new Dentist. I would like to schedule a time when you are expecting me so that I may drop off a sample of our "Welcome Kit" and explain the program in greater detail. Please reply to this email with your availability or call me at your earliest convenience. For a faster response, or if you prefer, feel free to text me on my cell which is listed in my signature. Thanks. Andi Hyman (571) 550-0359 [email protected]

Providing genuine, conservative, and affordable pediatric dental care in a warm and friendly atmosphere to the families of Ashburn, Leesburg, & One Loudoun

The goal of Dr. Chiara Rivas-Morello and the Pediatric Dentistry of One Loudoun team is to provide high-quality pediatric dental care to families in Ashburn, Leesburg, and One Loudoun, VA in an inviting, friendly, and comfortable environment. We seek to educate our patients and parents on the importance of prevention of dental decay and disease, and strive to keep our kids cavity-free. We believe in the importance of treating all our patients as if they were our own family and are confident in our ability to them with the care and expertise they deserve. From routine exams and cleanings to restorative treatments and even orthodontics, the dental care we provide is tailored to the unique needs of growing children and adolescents. We also offer nitrous oxide and/or sedation as needed to limit anxiety for patients in need of a little extra TLC. We understand that every child is different and has a unique set of requirements for a positive experience. We will customize your child’s visits to suit his or her individual personality and needs. We also invite parents to participate in their child’s oral health, so parents are always welcome in the treatment areas. Your concerns are our concerns, and we promise to listen to and address your needs. Start your child on the path to lifelong oral health. Contact our Ashburn dental office to schedule an appointment with Dr. Rivas-Morello and our team today!

Interesting fact, a Narwhal's horn is actually a tooth that can grow longer than 8 feet. They use this horn to taste chemicals in the water to find food. HOW GNARLY IS THAT?!

Interesting fact, on average a woman smiles 62 times a day. Men smile on average 8 times a day. Here is a picture of the PDOL team sharing their smile with you :)

Happy Toothsday !
Interesting fact about snails such as Gary, they have 14,000 to 20,000 teeth organized in rows on their tongues. That is more teeth than any other animal !

Dive into Toothsday!

Did you know, a dolphin's age can be determined by counting the rings of bone that grow around a single tooth. Also, their 40 plus facial muscles give them the appearance of a smile that is simply contagious 🐬

Happy Monday, make it a Monday full of smiles. Special shout out to our phenomenal dentist Chiara Rivas-Morello, Happy Birthday !


Did you know? Giraffes only have one row of 32 powerful bottom teeth. The same number of teeth as humans! They use their long tongues to pull their food into their mouths.

Select healthier treats to prevent cavities! Avoid those treats that are sour, sticky or chewy. Healthier snack options include veggies,fruits, nuts or cheese.

"Our tongues are one of the strongest muscles in the human body. Just like our finger prints, our tongues have their own unique print!" So just as a reminder for all your kiddos, aside from brushing 2x a day for two minutes, and flossing, give your tongue a nice scrub to maintain your unique healthy smile.
