Welcome to the neighborhood! As Sterling Ranch continues to grow into one of Colorado’s premier smart communities, families are looking for healthcare providers that match the area's innovative and high-standard lifestyle.

At Sierk Children’s Dentistry, we are proud to serve as the premier pediatric dental home for families in the 80125 zip code. Whether you are settling into Providence Village or Ascent, our nearby offices in Highlands Ranch and Castle Pines offer the specialized, kid-focused care your children deserve. We're a short 15-minute drive away.


Why Choose a Board-Certified Pediatric Specialist?

Many parents wonder if a general dentist is good enough for kids. While general dentists are talented, a board-certified pediatric dentist is a specialist who has completed two to three years of additional residency training beyond dental school. This training focuses exclusively on the unique oral health needs of infants, children, and adolescents, including those with special healthcare needs.

Establishing a dental home early ensures that your child’s oral development is monitored by experts who understand the nuances of growing primary teeth and developing jaws.

Meet the Experts Behind the Smiles

At Sierk Children’s Dentistry, we believe every child deserves a dentist who is not only an expert in clinical care but also an expert in kid-speak.

Dr. Jon Sierk: Board-Certified Pediatric Dentist

With over 20 years of experience, Dr. Sierk is dedicated to making dentistry fun and fear-free. He understands the importance of patience, clear communication, and a gentle touch. His vision for a tech-forward, patient-centered practice is why families from all over Douglas County, and Sterling Ranch, trust him with their children’s dental health.

Our Specialized Support Team

Our dental team is specifically trained to work with children of all temperaments. From our comfort specialists (our hygienists) to our front office team who helps you navigate insurance, we are all here to make your trip from 80125 as smooth as possible.


Your Child’s First Visit: Establishing Healthy Milestones

sierk children's dentistry logoWhen should your child first see a dentist? Both the ADA and the AAPD recommend the first visit by age one. These early visits are about more than just checking for cavities; they are about education, prevention, and getting your child comfortable in a dental environment.

We focus on:

  • Prevention: Fluoride treatments and BPA-free sealants to protect young enamel.
  • Education: Teaching Sterling Ranch parents the best ways to navigate brushing and nutrition during the toddler years.
  • Growth Monitoring: Ensuring that teeth are erupting correctly and identifying potential orthodontic issues early.

Care That Grows With Them: Specialized Dentistry for Teens

Many parents assume that once a child hits their teenage years, it’s time to move to a general dentist. However, the adolescent years bring unique dental challenges; from wisdom teeth monitoring to the oral health impacts of braces and high-performance sports.

We provide a sophisticated environment that respects our teen patients' maturity while providing the specialized expertise their developing smiles require.

  • Orthodontic Monitoring: We work closely with local orthodontists to ensure that while teeth are being straightened, they are also staying cavity-free.
  • Wisdom Teeth Guidance: We provide early assessment of third molars to prevent crowding or impaction before they become a problem.
  • Sports and Lifestyle: We offer custom-fit mouthguards for high school athletes and guidance on how nutrition and energy drinks impact teen tooth enamel.

Comfortable Care: Safe Sedation Options

We understand that for some children, and even teens, the dental chair can feel overwhelming. Whether your child has a severe gag reflex, high dental anxiety, or requires extensive restorative work, we offer safe, controlled sedation options to ensure a positive, trauma-free experience.

Laughing Gas (Nitrous Oxide)

This is our mildest form of sedation. It is a breathable gas that helps your child feel relaxed or "giddy." It wears off almost immediately after the mask is removed, meaning your child can return to school or play right away.

In-Office General Anesthesia

For children with significant dental phobias or those with special healthcare needs who cannot safely sit for a long procedure, we provide in-office general anesthesia.

  • Safety First: We partner with a board-certified anesthesiologist who monitors your child’s vitals (heart rate, blood pressure, and oxygen levels) throughout the entire procedure.
  • A One-and-Done Approach: This allows us to complete all necessary treatments in a single visit, sparing your child from multiple stressful appointments.

Serving the Active Sterling Ranch Community

We know Sterling Ranch families are active. Between hiking near Chatfield State Park and biking the neighborhood trails, accidents can happen.

  • Sports Mouthguards: If your child is participating in local youth sports, we provide custom-fit mouthguards that offer superior protection compared to "boil-and-bite" store versions.
  • Dental Emergencies: If a tooth is chipped or knocked out during a weekend adventure at Roxborough State Park, we are here to provide fast, compassionate emergency care for our patient family.

Frequently Asked Questions

Do you take my insurance?

Yes! We are in-network with many major providers, including Delta Dental, Cigna, and UnitedHealthcare. Our team is happy to help you navigate your benefits to ensure you maximize your coverage.

Is sedation safe for my child?

Absolutely. Safety is our top priority. Dr. Sierk has over 20 years of experience, and when deeper sedation is required, we bring in a specialist anesthesiologist to ensure your child receives hospital-grade safety in a comfortable office environment.

At what age should my child switch to an adult dentist?

There is no magic age, but we typically see patients through high school graduation. We find that teens appreciate the continuity of care and the fact that we already know their dental history and comfort levels.

Is the drive from Sterling Ranch worth it?

While there are general dentists closer to home, our offices are designed specifically for children. From overhead movies during treatment to our No Cavity Club and specialized behavioral techniques, we provide an experience that turns scary dental visits into something kids actually look forward to.

Can I stay with my child during the appointment?

Absolutely. We have an open door policy. We believe parents are our best partners in their child’s health, and you are always welcome to be present during exams and treatments.
