Childrens Preventative Treatment
When Should You Bring Your Child In?

If you think your child has a bite or orthodontic issues, early treatment is important. The younger your child is when you notice these problems, the easier the problem is to correct due to the growing tissues in the mouth.

Ages 6-9 are the ideal years for interceptive treatments to create space for permanent teeth,  align the jaws and bite, increase development of the airway.  Dr. Mergen is one of the few pediatric orthodontists in Eastern Iowa that offers early evaluation and prevention, which often results in fewer treatments in the future, less time spent in our office, less cost, and better results. Timing is key to prevention, and through early evaluation, you are taking a proactive step to eliminate complicated extensive treatment as well as the costs that go with it.  The great thing is Dr. Mergen uses Invisalign the most advanced orthodotnic care for all his patients.  He does not use bulky old school treatments such as headgear, expander, metal braces, and functional appliances.

What Types of Pediatric Issues Do We Treat?

When your child comes for their initial visit, we will evaluate their bite and make sure there’s enough room in their mouth for teeth to grow in and for the arch to develop. Frequently, children have alignment issues, such as:


  • Underbite
  • Overbite
  • Crossbite
  • Crooked teeth
  • Extra teeth that interfere with bite
  • Jaw growth problems or crowded teeth

We offer early treatment for these issues with options like Invisalign Teen that makes treatment easy for your child and eliminates bulky appliances like headgear, expanders, and spacers.

Invisalign First is used during interceptive and preventive treatment for children ages 6-10 for conditions such as narrow arches, severe crowding, impacted teeth, posterior crossbite and anterior crossbite (underbite). With Invisalign First, your child will have the advanced technology of the Invisalign system and its aligners, which are designed for patients who have a combination of baby and permanent teeth. LIke regular Invisalign, Invisalign First means no wires or brackets, fewer appointments, no food restrictions, and better results.
