Special Needs Dentistry for All Ages

Education in pediatric dentistry is accompanied with working with individuals that have special needs. Dr. Sierk understands that a warm, patient, caring and compassionate approach is necessary to soothe anxiety and help them feel safe in the dental chair.

Sedation dentistry services can help when treating children with special needs. Sierk Children’s Dentistry has an in-office anesthesiologist to help us administer sedatives. We also offer nitrous oxide (laughing gas), IV sedation, and more.

A Warm & Inviting Atmosphere

Our office is equipped with amenities such as televisions, headphones, and movies designed to help your child relax. Blankets and quiet rooms help children stay calm and focused. We also provide weighted blankets upon request for our special needs patients.

Scheduling at Sierk Children’s Dentistry is optimized to fit a parent’s busy lifestyle. With appointments available throughout the day, we accommodate your schedule.

Emergency Dentistry

Emergencies are unpredictable, so our 24 hour, on-call emergency services give your child access to the care needed. Dr. Jon Sierk is a member of a call group comprised of a group of pediatric specialists. This means that you will be able to get the best of care, even after normal office hours.
