Good oral health is a big deal, and it starts at an early age. That tenet forms the cornerstone of our practice and drives everything we do.

Starting with your child’s first visit, we take extra care to build a relationship based on trust with our pint-sized patients, and collaborating with parents is a big part of laying that foundation. Together, we can create a comfortable and stress-free experience that will set up your child for a lifetime of great oral habits and healthy smiles.

When oral emergencies or unexpected dental issues arise, we are ready to deliver best-in-class pediatric dental care that comes with a huge dose of compassion. We also provide nitrous sedation and sedation dentistry to provide an added level of comfort for our patients.

Dr. Bienstock is a board-certified pediatric dentist who treats children of all ages. She operates her practice in two convenient locations: Lake Pleasant Kids' Dentists and Orthodontics in Peoria, and Norterra Kids’ Dentistry and Orthodontics in North Phoenix.

From an early age, Dr. Bienstock realized that pediatric dentistry was her calling. After gaining exposure to the field through her brother’s dental practice, she became keenly aware of the fears many people face when it comes to visiting the dentist and resolved to create a practice that creates a comfortable, stress-free experience.

Starting her career at one of the premier pediatric dentistry practices in New York City, she quickly established herself as an empathetic and gentle professional who delivers exceptional care. Sometimes this means finding creative solutions to helping meet children’s needs – whether in the exam room or alleviating fears in the waiting room. In addition to routine early treatment, her pediatric specialties also include emergency dentistry, preventative dentistry as well as dental restorations, extractions and frenectomies. Further, she has developed an expertise in treating children with special needs and intellectual disabilities.

Charitably minded, Dr. Bienstock has also used her professional experience to lend a compassionate hand to Arizona Mission of Mercy, Healthy Children Healthy Families, the American Dental Association’s Give Kids A Smile Program and the Somos Amigos Dominican Republic Dental Outreach Mission Trip.

Kieara (Kiki) Miller
Dental Assistant

Kiki has been making smiles brighter for eight years, seven of which have been by Dr. Bienstock’s side. Kiki is both a dental assistant AND an orthodontic assistant, which is a perfect fit at our kids’ dental and orthodontics office! Kiki is originally from California but made Arizona her home when she was 18 years old. Fun fact: Kiki is a lefty, but she does everything right-handed…which can likely be blamed on her position as a dental assistant! Kiki has a positive energy that our patients love, and a contagious smile that we love having on our team!
