Our services

Our office

Because we specialize in the treatment of infants and children we have created an environment where kids of all ages feel comfortable. Our office was planned, designed, and built specifically for children. Every component of the office – from the colors, the layout, the equipment we use, and the movies we show during treatment, to the highly trained staff – is ALL about making your child comfortable and at ease.

Dr. Becker and her staff are friendly, highly-qualified, and know how to make your child’s dental experience surprisingly fun!

  • We are proud to use only the most advanced dental technology, while at the same time minimizing environmental impact. Our use of electronic records allows us to use a minimum of paper and ink. Through smart and environmentally conscious design, we have also minimized the use of dental lights and, where possible, utilize energy-saving fluorescent and LED bulbs.
  • We have eliminated the use of photo-processing chemicals by employing state-of-the-art digital radiography. We use only lead-free aprons to protect your child while radiographs are taken. All of our dental procedures are completed with mercury-free materials. Our use of materials that contain BPA is extremely limited. We are happy to provide lists of materials used upon request.
  • Kids On 1st Dentistry has made a point of acquiring recycled materials as well as energy-efficient equipment. We use only green products for cleaning the office. These products are not only healthy for the earth, but also – and equally important – they provide a healthy environment for your child and our staff.
  • We strive to reduce the production of garbage. We have set recycling bins throughout or office. All our sanitizers, wipes and soaps are environmentally friendly.

Uncompromising safety

Infection control is very important to us! We maintain strict sterilization and cross-contamination protocols. Come tour our office and visit the sterilization “zone.” See how serious we take our sterilization procedures that are designed to protect your child and our staff!

Our philosophy

We provide comprehensive treatment planning using state-of-the art materials and instruments. We believe in a conscientious and conservative approach to dental treatment. Should an emergency occur, we will make every effort to see and care for your child as soon as possible.

We will not rush you, we will listen to your concerns, and will give your child time to adapt to our dental office and make your child’s visits as comfortable as possible. We encourage you to schedule a tour of the office before your child’s appointment to familiarize yourself with our facility. Call and make a tour-visit appointment!

"Love! Love! Love! The best kids dentist ever! The kids are at ease and her bedside manner is amazing! She not only treats the kids but the parents. Very informative. Explains in detail and sets my mind at ease! Go!!!!!"



"We love Dr. Becker and her wonderful team! She is very knowledgeable, great with the kiddos, and got us in when there was an urgent need for our son. Our 3 boys love going there, enjoy their own tablets, movies, and cool toy incentives they provide. The environment is very clean, simple, yet inviting. Our middle son had some teeth pulled, and everything was on point and went so smoothly. I'm so glad we found Kids On 1st"



"Dr Becker is an amazing dentist. Very knowledgable and amazing bedside manner. Not only did she address my daughters concerns and fears wonderfully but she also put my mind at ease. After finding her, I can't imagine taking my daughter anywhere else."
