This means that our whimsical space is equipped with the safest, state-of-the-art equipment and materials to ensure that we treat each child with the highest standards.

Our Approach

Preventive Care

Routine dental appointments are at the heart of every preventive care routine. With regular visits, we’ll help your child avoid common dental issues.

Protect Little Teeth

Dental Fillings

Studies show that almost half of American children develop cavities. Dental fillings restore damage and prevent further decay.

Repair Cavities

Special Needs Care

We want everyone to feel comfortable in our office. We are sensitive to children with special needs, dietary restrictions, and allergies.

Accommodating Care

Dental Emergencies

Dental emergencies can be scary and stressful. Help your little one get the care they need, when they need it most with same-day emergency appointments.

Same-Day Care

"We had our first visit today with my son who is four years old. The office is beautiful and clean and everyone is very professional and kind. My son was nervous since it was his first time, but they made sure he had a good experience and finish the cleaning. We will be going here for many years to come!"

- Noelle


"We love treehouse pediatric dentistry. My daughter is 5 and is always so excited for her visits. Last time she was there she asked if she could schedule another appointment next week because she didn't want to wait 6 months. Everyone is extremely friendly and most importantly they explain everything they are doing to my daughter so she knows what to expect."
