Preventive Care

Root Canals



Dr. Sierk and his talented team of specialists in Highlands Ranch want your child’s first visit to their pediatric dentist to be both enjoyable and positive. The more informed your child is about dental care and the dental health services that they will be receiving, the more comfortable they will feel at our Highlands Ranch office. The AAPD, or American Academy of Pediatric Dentistry, says that children should seek pediatric dental care and first pediatric dental care services by their first birthday.  Your child’s newly-emerging teeth should receive proper pediatric dental care and benefit from dental care services in Highlands Ranch from the beginning of tooth emerging.

Dr. Sierk Pediatric Dentistry in Highlands Ranch's Guide to Effective Brushing and Flossing


  • At a 45-degree angle, place your toothbrush against your teeth
  • Brush gently back and forth in tooth-wide strokes
  • Move your brush to cover the chewing surfaces of every tooth, as well as the outer, and inner surfaces.
  • Using the tip of your toothbrush, brush the inner surface of the front of your teeth.
  • Replace your brush every three to four months, or if it begins to fray, as a frayed brush won't do a good job.
  • Use an ADA-accepted fluoride toothpaste


  • Take about 18 inches of floss and wrap most of the floss around your index finger. As the floss is used, you'll begin to unwrap this finger to use fresh sections on each gap, while wrapping the used floss around your other index finger.
  • Using your thumbs and forefingers, guide roughly one inch of floss between your teeth.
  • Gently glide the floss like a saw between your teeth, holding the floss tightly. Then, curving the floss into the shape of a letter "c" against one tooth, slide it beneath your gums.
  • Repeat process on each tooth, sliding up and down.
  • Contact Dr. Sierk pediatric dentistry in Highlands Ranch if you notice any signs of decay.

Preventing Tooth Decay with Dental Services

Many children in Highlands Ranch are not attentive to their dental care needs and are therefore at high risk for tooth decay. The routine of brushing and flossing, as well as regular visits to Dr. Sierk, a pediatric dentist in Highlands Ranch whose dental health services can help keep tooth decay at bay and their smile radiant.
